Description

[Detailed description of the invention]

The present invention relates to the technical field of electronic security systems for restricting access to premises and objects, such as buildings and computer programs. Private or public use! A number of electronic pica security systems have been designed to control access to fields and objects, such as proboscises, computer programs, stored computer information, and the like. All of these systems require the use of certain building preset codes to obtain the desired access. For example, many systems require that a person seeking such access submit a code or password to an electronic #ctIt, which the electronic device compares to a preset code and, if the two match, Open the operational or electronic lock to allow desired access. In such cases, the code is preset into the device and all authorized users are given the code. In other systems, the code is magnetically or otherwise encoded onto the card, the card is inserted into a reader, and the reader determines whether the encoded code is the same or older than the pre-existing ZT code. If they are the same, access is allowed. The problem with such systems is that once the code is known by a large group of users, it can be inadvertently given to t=j users. Even if possession of a physical device, such as an encrypted card, is necessary to gain access, such a card cannot be used once the card is known.

[Shima 5 and is easily given. The code is changed every time someone is suspected of having an unauthorized user's ρ゛ code, but the ijI code is all! 4F-t'
J must be given to the user. Furthermore, if fixed codes are used, methods have been found to break such codes. Once upon a time, 111 was not easy to break.
] There is a desire for a more sophisticated security system using threads. According to the invention, the security system generates a first variable that is displayed to the user. The user has a separate device into which this first variable is entered, and this device generates a second variable that has a specific relationship to the first variable. This second variable is entered into the security system by the user, and this system itself also generates the second variable. The second variables are compared and if they correspond, access is allowed. Thus, this system includes a first character generating mechanism for generating a first variable, and a second character generating mechanism for generating a related second variable having a predetermined relationship with respect to the first variable. a separate user-operated key mechanism for generating a corresponding second variable; a mechanism for the user to input this second variable into the system; and a separate user-operated key mechanism for generating a corresponding second variable; A character ratio flexible structure for comparing the second variable generated by the two-character generator MK and the second variable input by the user, and allowing access when the two variables correspond. and an access lock mechanism. The user-operated key mechanism for generating the second variable can take several forms, such as a numeric, alphabetic or similar table or a programmed dF calculator. In the system of the invention, the second variable, the code or password, depends on the first KKI, which is preferably randomly generated. Also, the relationship between the first variable and the second variable does not need to be known by the user, and is preferably not known. The user need only have access to a key or user operating mechanism to generate the second variable. This is a 61J with built-in program! When taking the form of a container, the relationship between the first variable and the second variable can be made very complex and almost impossible to decipher. Thus, the device for generating the second variable can be made almost impossible to copy, which makes it possible for only the person with this device to gain access to the protected property. Taste. Next, the manner in which the present invention is carried out will be explained with reference to the decorative drawings. Referring to FIG. 1, the basic components of the security system are shown in block form, and when access is desired, a first character generator generates characters or variables from a first set of variables. Occur. Such a first variable may be a single digit or a single letter of the alphabet, or multiple digits and or alphabetic characters, or other symbols. For example, the first letter or variable is the letter "EF". Preferably, the first character generator is a random character generator, and the first variable is randomly generated, or at least appears randomly generated to the user. Thus, the user does not know and cannot predict which variables will be generated by the first character generator. Once the first variable is generated, it is output from the system, such as by a display. Thus, the letters "EF" appear on an optical display such as a liquid crystal display or a light emitting diode display, or on a conventional cathode ray tube display used with computers. The second letter generator then generates the first letter. The first variable and the second variable can be related in a myriad of ways. They may be related by some function or mathematical relationship or The variables can be randomly associated by a preset table such as the table shown in Figure 1. In order for a user to "unlock" the system, the user must select the first variable displayed to him. and use the “key” to
An appropriate second variable must be determined. If the variables are related by tables, the authorized user will have a table such as the table of FIG. 2 in some form, for example on a cylinder as shown in FIG. 3. When the first variable is displayed as "EF", the user moves down the table of FIG. The user then enters the letter “T” into the system, for example through the keyboard, and the character comparator converts this user-generated second variable to the internally generated character “T” by a second character generator in the system. If both variables are the same, some type of locking mechanism is actuated and unlocked, allowing access to the infected object. Both numbers are not the same. If the user is given another opportunity to enter an answer, or a new first variable is generated, access is denied. For example, the first variable "CG" is generated and displayed. Now the user must type the character "D" to gain access.
must be entered. In the table of Figure 2, the first set of variables uses the letters A-1 (as the first character of the two character variables and the letters A-K as the second character).
Vine is created using the vine, which is all combinations of two characters. Although the table in FIG. 2 is shown as a simple table, in reality such a table could be much larger, making it difficult and time consuming to copy. Thus, the table can have h rows and columns for the entire alphabet and combinations of letters 1, ie uppercase and lowercase letters or letters and numbers 4. Very large dimples can be made. Furthermore, rather than being printed on a flat sheet of material, which is easily mechanically copied in chess printing, it can be provided in the form of a cylinder as shown in FIG. The cylinder is very difficult to copy with a copy machine, and 0)
Other shapes may also be used, especially those with curved surfaces such as spheres. The table surface may be coated with a colored material or filter that is difficult to copy, or the table itself may be made of a color that is not easy to copy. To increase the time and inconvenience of manually copying such tables, several sets of tables may be used. The sleight of hand variable may then refer to "CF", which means row "C', column"F" of the table "B". Instead of using a table, a program such as the handheld 74 instrument in FIG. A 7-gram embedded device may also be used. In such a case, when the system displays a first variable such as the number "15", this number is displayed on the keyboard 2.
1 is added to the calculator.岨J! The instrument is set to operate a preset program, which can be of any length and complexity, and to display the second variable via the display 22. The displayed variable is then entered into the system by the user, where it is compared to a second variable generated by the system's second character generator. On top of this, the ULF program is embedded h1°
Using calculators, the relationship between the first variable and the second σ) can be very complex, so it is difficult to determine such a relationship experimentally or to break the code. (
It is virtually impossible to "break the code".Also, depending on the temperature rise of the second variable, the first variable is actually two inputs into the instrument program. or 3 to be entered into the calculator as one entry.Thus, the first variant of the system is, for example, "2135".This means that in the preset program, the number 21 is entered into the calculator program. 1st σ) 11M was first put into the container as enF, and the salmon character 35 was ml-
This is entered as a second entry into the 1i-device program. However, this is all considered the primary variable in the system. Any type of programmable calculator may be used.5
However, a relatively simple circuit for use with the system is shown in FIG. National Sem1conductor C0
A single chip microcomputer ICI, such as PS 421L, is connected and programmed to handle all necessary machines. A 9 volt battery is connected through an on/off switch 24 to power the ICIK'. Any power source that provides ICI K positive voltage between 4 and 9 volts may be used. Resistor R1 and capacitor CI are ICI
is provided to set the frequency of the internal clock. In FIG. 5, the four 4825.26.27.28 are the four programmable output terminals A1 to ICI.
Connected to A4 and 4 programmed HJ'
tjtg input terminals B1 to D4 K-connected four conductors 291. phantom, 31 and 32 are arranged in a matrix to form a 4×4 matrix as shown. This matrix has 16 points where the conductor connected to the output terminal is opposite to the conductor converted to the input terminal. This matrix is physically located below the keyboard 21 (w, Figure 4) such that one key on the 16-key keyboard is above each of the 16 guiding points. Under normal conditions, the conductors touch at the intersection where they are shown reversing, so there is no contact between the output and input conductors. When a button is pressed, contact occurs between the input conductor and the output wire at the intersection below the button. This is the standard keyboard layout used on many hand-burning devices. The four output leads 125 to 125 are respectively connected to four single digit displays 133, 341, 35, and 38, which also constitute a display. Each single digit display is Li tr
onlx MAN-4. 7 additional programmable output terminals 01-C
7 are connected in parallel to each of the displays. Microcomputer ICI has 4 outputs 4 wires~28
ta: A program is installed to scan anti-temporarily,
A low signal, or zero volts, is applied sequentially to each of the four conductors while the remaining three conductors are at city volts, or +5 volts. This provides a single force to the keyboard matrix to sequentially activate each display. Each display is activated when its control input goes from +5 volts to zero volts. The scanning is rapid enough so that each display appears to be continuously turned on, although each display is activated sequentially. When a key on the keyboard 2 is pressed and the output conductor 6 to that one comes in contact with one of the input conductors 29 to 32, the input signal is transferred to one of the terminals A1 to A4 on the appropriate input terminal B1 to B4.
Appears with the output in . When button 121 on keyboard 2 is pressed, a high signal is generated on input conductor 30, which goes low when output conductor 27 goes low. represents the number "2" to the computer. Similarly, when other buttons on the keyboard 2 are pressed, other combinations of output signals and human input signals representing the respective number keys are generated. The scanning of the output conductors is Because it is so fast, the computer ICI is programmed to recognize several similar inputs as a single input and not require several input scans to separate consecutive inputs. Preliminary microcomputer ICI accepts the first variable entered by the user via the keyboard, and generates a variable that has a predetermined relationship with the first variable. For example, a given relation doubles the input, adds the relation, rotates it to the left, i.e. moves the leftmost digit of the answer to the rightmost position, and rotates the other digits. Thus, if the first variable was ``15'', the second variable would be (15X2) + (equity) =
Closed or 4 digits becomes 0080. After a left rotation, this second variable will be 0800K. The complexity of the relationship between the first variable and the second variable is limited only by the capabilities of the particular microcomputer used. The second fi determined by ICI is display 2
2 will be displayed on the screen. 7 output terminals 01~C7
Each of the seven segmen 1 that makes up each digit
Controls one segment of the target. Thus, a signal appears on terminals C1-C7 which causes each display to output the first digit of the calculated second variable on conductor δ.
The digit appears on display 33 as the leftmost digit of display 22. A signal appears on the terminals C1-C7, from which the display K forms the second position of the calculated variable at the same time as a low signal on conductor 2 (), from which K the digit is the first from the left side of the display 22. Similarly, the displays 35 and 3 forming the display 22 in the third and fourth positions from the left side of the display 22
6 appears at the same time as conductor 27 and public low (i4). The chip for the ICI is ordered from the chip manufacturer along with memory containing a specific program designed by the system manufacturer. The programs described above are designed by a system designer for use with a particular system or set of systems, and then supplied to a system designer and supplied to a system user as a pre-programmed unit. Microcomputer chips with field-programmable memory but otherwise similar to ICIK, e.g., National Semicon
ductor C0P402 is used, which is not programmed by the chip manufacturer according to the system designer's specifications, but is actually programmed by the system designer himself and then used in the system as a pre-programmed unit. The same can be supplied to persons with disabilities. A similar hand-held, programmed calculator may be used without a keyboard or display. That is,
The user plugs the calculator directly into the socket associated with the system, the system supplies the first variable directly to the calculator, and the calculator generates the second variable and sends it to the system. so that it is directly supplied back to the In this case, the user simply plugs the ``key'' into the system to unlock it, but the user is still concerned with the supply of Therefore, the calculator device or "Key 1" is still considered a user-operated device for determining the second variable, and the user applies human power to the calculator by plugging it into the calculator. and a second variable into the system. One useful use of the system of the present invention is to protect computer programs from unauthorized use. Most computers today are general purpose computers. They are not programmed to perform specific tasks and are not specially wired to perform these tasks.
Programs that make computers more capable of doing certain tasks are of great value. however,
Most programs are distributed on 1i tapes or disks, and therefore programs can be easily copied from one tape or disk to another. moreover,
Once a program is installed on a computer, that computer can, in some cases, transfer the program to another computer. Prior art program security systems make it difficult to copy a program from one disk or tape to another by placing the program code in areas of the disk that cannot normally be copied. I am trying. However, such systems are generally easy to break. The present system is not intended to prevent the actual copying of programs, but rather limits access to programs to those who can use them. Thus, a program may be copied from disk or tape but cannot be used unless it passes through the disclosed security one-hit system. To use such a system with a computer program, when the program is called for use in the computer, the program itself generates and displays a first variable. The type of display will vary with the computer equipment used. After displaying the first variable, the user must then determine the second variable and enter it into the computer. The computer is programmed to generate the second variable on its own and compare it to the second variable entered by the user. If they do, the program effectively unlocks itself and the computer begins operating the program. If they do not correspond, the computer can generate a second first variable or can be set to dump the program from its memory or take other reasonable action. can. It has generally been found that satisfactory security is obtained if the user is given three opportunities to present the correct second variable to Di that dumps the program from its memory. this is,
Even if the user has the correct "key," it allows for mistakes the user may make in determining the second variable, but does not allow for infinite trial and error. The program may be set up in a preset manner for use in a computer so that it needs to be supplied at various other locations and activated only at certain times. For example, a program is called for use in a computer and functions normally, but at some random point during use it generates a first variable and sets a second variable before continuing its operation. can be pressed. It has been found particularly useful to request system behavior at critical functional points in a program. for example,
Candy processing programs generally require that after a new document is created or an edit to a document is completed, the new or edited document must be archived and stored. After the creation of a document or the writing of that document, it is desirable to generate a second vibration and to require its input into the computer by the user. (difficult), if the user is unable to manually set the exact variables,
The user will not be able to memorize the document and his work will be lost. Instead of requiring a variable every time a document is to be stored, it may be desirable to manually request the second variable only sometimes when a document is to be stored. The second variable σ) Whether an input is required depends on the length of the document to be remembered or on the number of keystrokes that are moved in the creation or editing of the document, so that the program is shortened. It works fine for documents, but only after the user has expended a lot of time and energy is the user actually used by manual labor of precise variables and 70) is the result of the effort. Require the user to demonstrate that he or she stands to lose. It should be understood that there are an endless variety of ways to actually use or implement a security system with a computer program. The actual programming of the system varies from program to program and with the equipment into which the protection program is folded. However, such programming will be obvious to those skilled in the art from the above description of the system and will therefore not be detailed here. Although the actual relationship between the first variable and the second variable is determined by the programmer and included in the program when written or determined by the computer unit supplier, the same relationship may be ”
disclosed to the programmer for inclusion in the program. The complexity between the first variable and the second variable and the way in which the user generates the second variable will vary with the value of the program being stored. Thus, in a computer game program where the cost of the program itself is only about $100,000, the user is allowed to use an inexpensive computer chair like the table υ) type mentioned in h11 along with the program. will be supplied to If a complex data processing program costing more than 1,000 dollars is to be maintained, a digital chair such as a push-button calculator with a programm installed in advance may be used and Brokram's w+
hj is supplied to the user. A presently preferred embodiment of an eyeliner unit for use with a computer is illustrated in FIG. Not hand-held, this calculator 40 requires no connection to a computer and is designed to be surfaced on a computer keyboard 41, and the unit 40
can be mounted at any location around the keyboard that does not interfere with normal computer operation. Unit 40&'
It may be secured to the keyboard or other area of the chestnut station by packaging means such as adhesive or other adhesives. Unit 40 may also be stored as a portable unit and not secured at all. The unit 40 is designed to be used by many different programs that can be protected by the system and operated on the same computer. Although additional keys may be provided, it has been found that six keys are sufficient for the purposes of the present invention. In addition to the keyboard 42, the unit 40 has a receiving pocket 45 for receiving and retaining an enter key, a display 44, and an integrated circuit package 46 in the connection system. A program generally has its own individual formula relating the first and second variables.In the calculator unit shown in Figure 6, instead of separate dL calculator units for each program, the same unit However, instead of a pre-programmed formula and sometimes other optical calculators for each program, the user is supplied with an individual integrated circuit package 4b for each program. When a program is to be used on a computer,
COGRAM's related integrated circuit packages are common total JI1. is plugged into the device unit 40. The circuit of the meter unit 40 is similar to that shown in FIG. 5 for the itN unit 2iJK of FIG.
The number of moths in the key is 16 in the 10-meter scale, but N1
There is an obvious change to the number of keys in the JL device 40, which is seven, so there is a slight difference in the number of keys. The multiplier-sum circuit microcomputer unit ICI of FIG. 5 is the removable integrated circuit package 46 of FIG. 6.7. It will be understood that the circuit shown in FIG. 5 is merely exemplary and that many obvious changes may be made to adapt the invention to a computer unit or divine circuitry in the form of a yuzu. Should. In the basic system described above, the computer program or other locking device generates m variables and prompts the user to generate and input a second variable, thereby causing each time the second variable is requested. Kuuse Nagisa requests that the variables of 絽 be inputted into the temporary calculator unit. In some cases it is desirable to eliminate some of the steps and automatic generation of variables is provided for this purpose. In the self-ktJ generation of a variable, not only is the second variable related to the first variable by a certain predetermined relationship, but also the subsequent first variable and second variable are also related by a certain rectangular connection thread. s1',n, so that both the instrument and the computer know whether the following variable should be . Thus, once a first variable is generated by the program and entered into the ttN generator unit by the user, the corresponding second variable totals 1. Once generated by the calculator unit and entered into the computer, the program and the calculator are synchronized. The program and calculator are one, and the user sets the first variable to 1i.
ij! It is advantageous to actually enter the keystrokes 1'l='/', so that the subsequent 1'L catfish and their associated second variables can be generated on purpose. In use, after synchronization,
When the program requires input of the second variable, the user presses the enter button 4:3 on the machine and the correct second variable is displayed by the display 44. This saves the user the time required to enter the d1 specialized unit in the first kosaku naki operation. The user still has to enter the displayed second variable into the computer. I) 4 = constant 1 IAI for the first variable generated earlier
Instead of automatically generating the first ilx by the function and then generating the corresponding second variable, the second ih directly generates the previous second variable when the enter key is pressed. ) The second strange thing to be born! Father (Yortsu) ``You can spin one string and get one string.'' The actual method used to generate variables and manipulate the program is Programmer's Choice #4. If the computer program and the calculator unit are not synchronized and a wrong second variable is entered into the computer, or if for some unknown reason the user enters the wrong second variable. , the computer program generates a new first variable and requires the user to carry out the entire process of generating the second variable.The computer program also generates a new first variable and requires the user to carry out the entire process of generating the second variable. It is also possible to request that the entire process of actually keying in one variable be performed in sequence, so that the user is actually an authorized user and immediately before the set of consecutive second variables. In addition, the program keeps track of the number of times an incorrect second variable is entered, directing unauthorized use of the program as much as possible, and ensuring that the wrong engine of a certain ship is not entered.
It is programmed to take actions such as delaying or denying post-IJ operation 1-. Convenient operation-saving steps for generating the second variable (i.e., the indicator unit itself has an information processing function,
This also allows you to track specific events such as the number of times it was used, date, time, etc. In fact, the meter unit 40 also incorporates a standard calendar circuit, so that when the display gray 44 does not indicate a second variable, it appears to indicate the time and/or date. is preferred. An information processor or integrated circuit 46 allows the system to enable computer programs and calculators to actually communicate information between each other, in addition to simply generating first and second variables. It is composed of 5. For the purpose of information transfer, the computer program generates a message for the information, which is typically 7f on the first +4 number.
- and cannot be distinguished from the first variable by the user, but is distinguishable and beaten by the GI unit. "[The n-unit is responsive to the computer and is generally in a four-dimensional format with that of the second information and co-supplies the user with the required information which is also indistinguishable from the small variables. For example, If the computer program wants to know the date or time, it sends a request to the gF calculator and the calculator supplies the date and time information.The program sends a second IN information. If it wishes to know of a recovery in which the odometer unit has been used to generate a In addition to the direct information request and direct response, some information is encoded onto the actual first and second variables. encoded,
The computer program can determine whether the second variable being entered into it is a generated measure or comes from a list of previously generated variables. If desired, the program can require that all valid second variables entered also contain current date or time information. Second, once the time and/or date information encoded in variables is entered into the computer, it is possible to restrict access depending on the time and date. It is thus f5rM1 that the program can only be used during certain times of the day or only on certain days of the week or year.
In the case where sell. If a prohibited time is indicated, the appropriate step is taken by the program and access is not allowed ='1. In some cases, if the date, time encoded in the second variable is sent to the computer, it becomes a valid second variable, or the button occurs during another time. If it is, it is changed by the computer to the valid second variable VC, enough so that it is no longer f[a. Wl' calculator was used to generate the second variable 1
If broad tracking is possible, it can be programmed to stop generating the second variable after a predetermined number of uses. This percentage fee may be used advantageously in connection with the rental of software where only trial use of the software or use of a certain number of programs is permitted or paid. In a #1 calculator arrangement as shown in Figure 6, it is advantageous to have a master type integrated circuit available if the user has several programs stored by the system. It is. This integrated circuit is capable of absorbing and retaining the programs and program variables contained in each of the individual integrated circuits, which are supplied as individual integrated circuit packages 46 with each of the individual 7 grammes. In some cases, one integrated circuit package 46 may be used with several different insured programs. In order to program the master unit, the user's specialized equipment must incorporate the program to facilitate the absorption and transfer of programs and variables from each integrated circuit package into the master output circuit. There must be. If the user's tri-A device does not have that capability, the user may also use a master integrated circuit created by the software vendor or other competent party. can. In addition to providing computer programmatic protection, such systems are effectively used in computers to control access to certain data stored in the computer. Instead of having computer programs or information stored in a computer where the system's program is embedded in the computer, the system uses a microcomputer embedded with a program to operate as described above. 1 or each block of FIG. 1 can be easily configured to operate an electrically operated lock to protect property from unauthorized entry. A system (the door to the room must have an electrically actuated lock, non-explosion) is provided in close proximity to the lock or at a remote location, and a button is pressed to energize the system and the first variable is The person operating the system then determines a second variable and enters it into the system. If the second variable is accurate, the system activates the lock. This opens the door from K and allows access to a specific location.The components and routes suitable for such a system will be obvious to those skilled in the electronics technology and will not be described in detail here. Although the invention has been illustrated and described with respect to particular embodiments that are considered to be the best mode for carrying out the invention, there is no intention to depart from the broader inventive concept disclosed and claimed. It is to be understood that various changes may be made to adapt the invention to different embodiments.
