Description
Technical Field
The invention relates to the technical field of USB flash disks, in particular to a data self-destruction system of a USB flash disk with a fingerprint identification function.
Background
The USB flash drive is a universal USB flash drive and is named as 'USB-flash-disk' in English. The USB interface is used for connecting with a computer to realize plug and play, and is a miniature high-capacity mobile storage product without a physical driver. The U disk was originally named as a novel storage device produced by luckiness science and technology, namely a U disk, and is connected by a USB interface. After the USB flash disk is connected to the USB interface of the computer, the data of the USB flash disk can be exchanged with the computer. Since luck has already made patent registration, the device of similar technology produced later cannot be called "U disk" any more, but is called "U disk" of harmonic sound "
The USB flash disk is deeply loved by people, the shadow of the USB flash disk can be seen everywhere in people's daily life, and they keep a large amount of files that people need, but because the head of the USB flash disk is less, cause the loss of USB flash disk easily, because current USB flash disk does not have the setting that can self-protect, the USB flash disk of loss is picked up by other people easily to cause the leakage of the inside file of USB flash disk, cause the influence that to a certain extent is not good, also probably can directly lead to economic loss.
Disclosure of Invention
The invention provides a data self-destruction system of a USB flash disk with a fingerprint identification function, which has the advantages that the USB flash disk can protect the USB flash disk, prevents other people from knowing files in the USB flash disk, and solves the problems in the background technology.
The invention provides the following technical scheme: a data self-destruction system of a USB flash disk with a fingerprint identification function realizes the data self-destruction function of the USB flash disk so as to protect the data security of a lost USB flash disk, and comprises the following modules: the fingerprint detection device comprises a fingerprint management module, an input module, a detection module, a judgment module, an opening module and a self-destruction module;
fingerprint management module:
the USB flash disk protection device is used for storing fingerprints input by a user and realizing self-protection of the USB flash disk.
A logging module:
the fingerprint of the user is input into the fingerprint management module by acquiring, processing and extracting the fingerprint image of the user.
A detection module:
the user need carry out input once more to the fingerprint when using this USB flash disk to fingerprint when accomplishing the use once compares with the fingerprint before using, thereby detection module detects the inside user's fingerprint of fingerprint management module, and the fingerprint of type when the user uses.
A judging module:
when the detection module detects the fingerprints of the user during use and the fingerprints before use, the judgment module compares the fingerprints of the user and the fingerprints of the user simultaneously and judges whether the fingerprints of the user and the fingerprints of the user are consistent or not, so that whether the USB flash disk is opened or the files inside the USB flash disk are self-destructed is judged.
Opening the module:
when the judgment module judges that the fingerprints of the USB flash disk and the fingerprint of the USB flash disk are consistent, the module is opened to connect a circuit of the USB flash disk, so that a user can continue to use the USB flash disk.
Self-destruction module
When the detection module judges that the fingerprints of the USB flash disk and the USB flash disk are inconsistent, the self-destruction module directly starts an internal program to erase the data in the USB flash disk and the fingerprints recorded in the fingerprint management module, so that the file in the USB flash disk is prevented from being leaked.
Preferably, when the fingerprint is input for the first time, the input module needs to input the same fingerprint for three times, the input module has input of the auxiliary fingerprint, the input of the auxiliary fingerprint also needs to input the same fingerprint for three times, and when the input of the fingerprint for the first time and the input of the auxiliary fingerprint are completed, the input module automatically stores the fingerprint and the auxiliary fingerprint into the fingerprint management module.
Preferably, when the USB flash disk is used, a user needs to perform authentication three times, and the detection module needs to perform detection three times, so that the correctness of the input fingerprint during use is ensured, the problem of misjudgment is prevented, and the loss of files is avoided.
Preferably, after the fingerprints are successfully compared, the opening module sends information to the fingerprint management module, the fingerprint management module sends a semaphore for successful fingerprint comparison to the GD32, so that the circuit is switched on and a control semaphore is sent, the two pin circuits (D +, D-) of the usb disk data signal circuit are switched on through the CH440 series chips of the integrated circuit, the computer system can see that the usb disk is connected to the system, and at this time, a user can normally use the usb disk.
Preferably, after the fingerprint comparison fails, the USB flash disk starts the data self-destruction module to perform multiple rounds of coverage erasing on the data in the storage area, so that the data of the USB flash disk is protected from being read by unauthorized people, and the data security is protected.
Preferably, the main authorizer and the secondary authorizer can both perform successful fingerprint comparison, so that the U disk is only used by the two users.
The invention has the following beneficial effects:
1. this data self-destruction system with fingerprint identification function USB flash disk, through setting up fingerprint management module, type module and detection module, when the user takes this USB flash disk for the first time, can carry out the type-in of first fingerprint, make the USB flash disk authorize the use to this user, and there are a plurality of fingerprint management systems in the fingerprint management module inside, the USB flash disk can carry out fingerprint type-in to the second person, and authorize the second person, and type module and detection module all can use both, make the practicality of USB flash disk strengthen, the while USB flash disk further strengthens the consciousness of self-protection, when avoiding appearing other people and picking up the USB flash disk, the condition of the inside file of USB flash disk, detection module can carry out the detection of fingerprint to the people who uses this USB flash disk, thereby carry out the operation of opening the USB flash disk on next step, make the security of USB flash disk improve.
2. The data self-destruction system of the USB flash disk with the fingerprint identification function has the advantages that through the judgment module, the opening module and the self-destruction module, when a user compares the fingerprint with the fingerprint at the correct position through the detection module and the judgment module, namely, the information can be sent to the fingerprint management module through the opening module, the fingerprint management module, the GD32 and the integrated circuit switch chip CH440 are matched with each other, thereby opening the USB flash disk, enabling the computer to see the USB flash disk to be accessed into the system, thereby completing the use, the self-destruction module automatically starts the self-destruction program after the fingerprint comparison is unsuccessful, thereby repeatedly deleting the files in the U disk and the fingerprints in the fingerprint management module, ensuring that the files in the U disk and the fingerprints in the fingerprint management module are not leaked, therefore, the safety of the USB flash disk is effectively guaranteed, and the condition that the USB flash disk is lost and internal files are leaked is avoided.
