The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The embodiment of the application provides a signature information processing method, which is applied to a server side, as shown in fig. 1, and comprises the following steps:
Step S101: the method comprises the steps of obtaining original information to be signed, pre-analyzing the original information to be signed, generating the information to be signed, wherein the information to be signed accords with a transaction message format, and the information to be signed comprises a first hash value of the information to be signed.
It will be appreciated that the original transaction data may be information of the type of transaction, account number, password, transaction amount, transaction time, transaction serial number, etc. obtained from the bank server.
Optionally, in order to ensure that the transaction data to be confirmed is not tampered and improve the signature efficiency of the terminal, format analysis can be performed on the original transaction data at the server side in advance, optionally, the server side can be an upper computer, the upper computer refers to a computer capable of sending a control command, the computer for providing services can also be referred to as an upper computer, and the terminal can be signature authentication equipment.
The signature authentication equipment needs to communicate with the upper computer, and the signature authentication equipment and the upper computer interact in a command and response mode to cooperatively complete the transaction; specifically, after the upper computer obtains the original transaction data, the original transaction data is pre-parsed to obtain the data to be transacted, wherein the upper computer judges the message format of the original transaction data plaintext when the original transaction data is pre-parsed, and if the message format of the original transaction data plaintext is wrong, namely, the data to be transacted does not accord with the transaction message format, the error information can be returned to the bank server so as to enable the bank server to continue processing.
If the message format of the plaintext of the original transaction data is correct, the original transaction data is not tampered, and the original transaction data can be sent to a terminal such as signature authentication equipment for signature authentication by a user; the upper computer can also calculate a first hash value of the data to be transacted and send the first hash value to the signature authentication equipment for subsequent verification.
It should be noted that, the original information to be signed may also be directly sent to the terminal, the terminal pre-parses the original information to be signed, that is, performs judgment of the message format of the original information to be signed, calculates the first hash value thereof, if the message format is wrong, the message is wrongly and safely withdrawn, and if the message format is correct, the first hash value is cached for subsequent verification. It can be understood that the server, that is, the upper computer, is used for judging the message format and calculating the first hash value, so that the processing efficiency of the signature information can be improved.
Step S102: dividing the information to be signed to generate a plurality of sub-information to be signed, and adding identifiers for the plurality of sub-information to be signed respectively;
Step S103: and transmitting the sub-information to be signed meeting the preset condition to the terminal based on the identification of the sub-information to be signed, so that the terminal displays the sub-information to be signed meeting the preset condition.
It can be understood that when the terminal, such as the signature authentication device, displays the transaction data to be confirmed meeting the predetermined condition, since the buffer area in the signature authentication device is generally smaller, the terminal can display the transaction data to be confirmed, such as personal transaction data, with smaller magnitude; however, when transaction data to be confirmed, such as transaction data of a company or a school, with a large magnitude is required to be displayed, there is a case that the transaction data is not completely displayed, so that signature authentication cannot be performed on the transaction data with the large magnitude. Therefore, the transaction data to be confirmed can be subjected to segmentation processing, so that the sub-data to be confirmed generated after segmentation can be completely displayed on the signature authentication device.
It should be noted that, the dividing processing operation of the transaction data to be confirmed may be performed at the signature authentication device or at the upper computer, but in order that the signature authentication device may efficiently process the display situation, the dividing processing is generally performed at the upper computer to generate a plurality of transaction sub-data to be confirmed, and an identifier is added to the plurality of transaction sub-data to be confirmed, where the identifier includes not only which transaction data to be confirmed the transaction sub-data belongs to, but also an identifier number for belonging to the same transaction data to be confirmed.
After the upper computer obtains the identification of the transaction sub-data to be confirmed, the transaction sub-data to be confirmed meeting the preset condition can be sent to the signature authentication equipment according to the identification of the transaction sub-data to be confirmed, so that the signature authentication equipment can display the transaction sub-data to be confirmed meeting the preset condition, and then the user can conduct signature authentication on the displayed transaction sub-data to be confirmed meeting the preset condition, and the transaction is completed.
Optionally, when the server sends the sub-information to be signed meeting the predetermined condition to the terminal based on the identifier of the sub-information to be signed, the sub-information to be signed further includes a first hash value, and in the process of sending the first hash value of the sub-information to be signed to the terminal, the server may encrypt the first hash value by using a private key of a preset asymmetric key and then send the encrypted first hash value to the terminal in a ciphertext manner.
According to the method, the original information to be signed is obtained, the original information to be signed is pre-parsed, the information to be signed is generated, the information to be signed accords with a transaction message format, and the accuracy of the original information to be signed is guaranteed; the information to be signed comprises a first hash value of the information to be signed, and the first hash value is used for subsequent verification; and the server divides the information to be signed to generate a plurality of sub-information to be signed, so that the processing efficiency of the information to be signed can be improved, the identification is added to the information to be signed, and the sub-information to be signed meeting the preset condition is sent to the terminal, so that the terminal can display the sub-information to be signed meeting the preset condition in a segmented manner, signature authentication of the large-scale information to be signed is completed, and the integrity of signature authentication of the information to be signed is ensured.
Optionally, based on the identification of the sub-information to be signed, the sub-information to be signed meeting the predetermined condition is sent to the terminal, so that the terminal displays the sub-information to be signed meeting the predetermined condition, including:
and receiving a page turning instruction sent by the terminal, and sending first sub-information to be signed corresponding to the first identifier to the terminal based on the first identifier included in the page turning instruction so as to enable the terminal to display the first sub-information to be signed.
It can be understood that, after the to-be-confirmed transaction sub-data sent to the signature authentication device by the upper computer is confirmed by the user, the page turning instruction sent by the terminal may be received, and specifically, the upper computer may send the first to-be-confirmed transaction sub-data corresponding to the first identifier to the signature authentication device for the user to confirm continuously based on the first identifier included in the page turning instruction.
The segmentation request of the signature authentication equipment is transmitted by the segmentation of the upper computer, so that large-magnitude transaction data to be confirmed can be displayed in the signature authentication equipment.
Optionally, based on the identification of the sub-information to be signed, the sub-information to be signed meeting the predetermined condition is sent to the terminal, so that the terminal displays the sub-information to be signed meeting the predetermined condition, including:
acquiring a second identifier of second sub-information to be signed currently displayed by the terminal;
And determining at least one third identifier with a number larger than that of the second identifier based on the number of the second identifier, and sending at least one piece of third sub-information to be signed corresponding to the at least one third identifier to the terminal so that the terminal displays the third sub-information to be signed.
It can be understood that when the user needs to turn pages and browse, the signature authentication device reports the identification of the transaction sub-data to be confirmed, which is required to be displayed and corresponds to the page turning instruction, to the upper computer, and the upper computer sends the transaction sub-data to be confirmed to the signature authentication device based on the identification of the transaction sub-data to be confirmed.
In order to reduce the workload of the signature authentication device and improve the working efficiency of the signature device, the embodiment also provides an optimized scheme, and the upper computer can actively send the transaction sub-data to be confirmed, which is required to be displayed by the signature authentication device.
Specifically, the upper computer can actively acquire the identifier of the transaction sub-data to be confirmed currently displayed by the signature authentication device, and because the identifier contains the number information, at least one third identifier larger than the identifier number can be confirmed according to the identifier number of the transaction sub-data to be confirmed currently displayed, and then the third transaction sub-data to be confirmed corresponding to the third identifier is sent to the signature authentication device, so that when the signature authentication device needs to display the third transaction sub-data to be confirmed, the identifier can be directly acquired inside the signature authentication device without sending an acquisition request to the upper computer, and the display time is saved.
The embodiment of the application provides a signature information display method, which is applied to a terminal, as shown in fig. 2, and comprises the following steps:
Step S201: receiving sub-information to be signed, which is sent by a server and meets a preset condition, wherein the sub-information to be signed, which meets the preset condition, comprises a first hash value.
After receiving the sub-information to be signed meeting the preset condition sent by the server, the terminal can send the sub-information to be signed meeting the preset condition to the display storage area, and when the terminal, namely the signature authentication equipment has a display requirement, the sub-information to be signed stored in the display storage area is displayed.
In one embodiment of the invention, the sub-information to be signed meeting the preset condition sent by the server is received, the sub-information to be signed meeting the preset condition accords with the format of the transaction message,
And analyzing the transaction message format of the signature sub-information meeting the preset condition, and extracting displayable information of the sub-information to be signed meeting the preset condition.
It can be understood that after the terminal receives the sub-information to be signed, which satisfies the predetermined condition and is sent by the server, the terminal can extract the displayable information in the sub-information to be signed by analyzing the format of the transaction message in the sub-information to be signed, then store the displayable information in the display storage area, and when the terminal, that is, the signature authentication device has a display requirement, display the displayable information stored in the display storage area.
It can be understood that when receiving the sub-information to be signed, the terminal also receives the first hash value in the sub-information to be signed. Specifically, the terminal may obtain the first hash value of the sub-information to be signed by decrypting the sub-information to be signed.
In one embodiment of the present invention, the terminal may decrypt the ciphertext segment in the sub-information to be signed using the preset public key to obtain the first hash value in the sub-information to be signed, corresponding to the server encrypting and transmitting the first hash value.
Optionally, the terminal may further store the decrypted first hash value in a specific hash cache area for subsequent verification.
Optionally, receiving sub-information to be signed, which is sent by the server and meets a predetermined condition, includes:
sending a page turning instruction to a server so that the server obtains first sub-information to be signed corresponding to a first identifier based on the first identifier included in the page turning instruction;
and receiving the first sub-information to be signed sent by the server.
It can be understood that, when the transaction sub-data to be confirmed displayed on the signature authentication device is confirmed by the user, the user has a need to view the next transaction sub-data to be confirmed, so that the user clicks the page turning button displayed on the signature authentication device, and then the signature authentication device sends a page turning instruction to the upper computer.
The page turning instruction comprises an identifier of next transaction sub-data to be confirmed, so that the upper computer can acquire first transaction sub-data to be confirmed corresponding to the first identifier based on the first identifier included in the page turning instruction and send the first transaction sub-data to the signature authentication equipment, and the signature authentication equipment can store the first transaction sub-data to be confirmed into a display storage area and then display the first transaction sub-data to be confirmed when acquiring the first transaction sub-data to be confirmed corresponding to the page turning instruction.
Optionally, receiving sub-information to be signed, which is sent by the server and meets a predetermined condition, includes:
Transmitting a second identifier of the second sub-information to be signed which is currently displayed to a server, so that the server determines at least one third sub-information to be signed corresponding to at least one third identifier with a number greater than that of the second identifier based on the number of the second identifier;
And receiving at least one piece of third sub-information to be signed sent by the server.
It can be understood that, in order to reduce the workload of the signature authentication device and improve the working efficiency of the signature device, the identifier of the second transaction sub-data to be confirmed currently displayed can be sent to the upper computer, and because the identifier contains the number information, the upper computer can confirm at least one third identifier larger than the identifier number according to the identifier number of the second transaction sub-data to be confirmed currently displayed, then send the third transaction sub-data to be confirmed corresponding to the third identifier to the signature authentication device, the signature authentication device acquires the third transaction sub-data to be confirmed and stores the third transaction sub-data in the display storage area, and when the third transaction sub-data to be confirmed needs to be displayed, the third transaction sub-data to be confirmed can be directly acquired in the upper computer, and the acquisition request is not required to be sent to the upper computer, so that the display time is saved.
Optionally, when the total memory size occupied by storing the sub-information to be signed in the preset buffer area exceeds a preset threshold, sequentially deleting the sub-information to be signed which is ordered to be front according to the number from small to large based on the number of the identifier of the sub-information to be signed.
It can be appreciated that, because the display storage area in the signature authentication device is limited, if the continuous transaction sub-data to be confirmed is stored in the display storage area, the subsequent transaction sub-data to be confirmed cannot be displayed, so that when the stored transaction sub-data to be confirmed in the display storage area reaches a certain threshold, for example, exceeds eighty percent of the memory in the display storage area, a part of the transaction sub-data to be confirmed is deleted, so that the service performance of the signature authentication device is maintained.
Optionally, a part of the transaction sub-data to be confirmed may be deleted according to the identification number of the transaction sub-data to be confirmed, specifically, the transaction sub-data to be confirmed stored in the display storage area may be sorted according to the order of the identification numbers from small to large, and the transaction sub-data to be confirmed with the smaller identification number may be deleted.
It can be understood that the smaller the identification number is, the smaller the identification number indicates that the transaction sub-data to be confirmed corresponding to the identification number has been confirmed by the user, so that the part of data can be deleted, and further, the signature authentication device can display the transaction data to be confirmed with infinite length.
Step S202: and calculating a second hash value of the sub-information to be signed, which meets the preset condition, and displaying the sub-information to be signed, which meets the preset condition, under the condition that the first hash value is matched with the second hash value.
It will be appreciated that to ensure the security of the transaction data, the transaction data may also be verified at the signature authentication device to ensure that the accurate transaction data is displayed to the user. Specifically, after receiving the transaction sub-data to be confirmed sent by the upper computer, the signature authentication device can calculate a second hash value of the transaction sub-data to be confirmed, after calculating the second hash value of the transaction sub-data, the signature authentication device can decrypt the transaction sub-data with the terminal and store the second hash value in the hash cache area for matching, when the calculated hash value is consistent with the decrypted hash value, the signature authentication device indicates that the transaction sub-data has uniqueness and reliability, the signature authentication device can display the transaction sub-data to be confirmed for a user to confirm, and the user can perform signature operation, so that the effect of 'what you see is signed' is truly achieved.
In one embodiment of the present invention, when the first hash value matches the second hash value, the signature authentication device may further display displayable information stored in the display storage area, so that the user may confirm, and the user may perform a signature operation, so as to achieve the effect of "what you see is what you sign".
Optionally, in order to improve the checking efficiency of the signature authentication device, before calculating the second hash value of the transaction sub-data to be confirmed, compression processing may be performed on the transaction sub-data to be confirmed, then the second hash value of the compressed data is calculated, the hash value of the compressed data is matched with the first hash value, the signature sub-data to be confirmed that is successfully matched is displayed for the user to confirm, and the user may perform a signature operation to realize "what you see is what you sign".
According to the method and the device for signing the sub-information to be signed, the received sub-information to be signed meeting the preset conditions is stored in the display buffer area, the service performance of the terminal for displaying the sub-information to be signed is guaranteed, the second hash value of the sub-information to be signed is calculated, and the sub-information to be signed is displayed under the condition that the calculated second hash value is matched with the decrypted first hash value, so that the signature is realized, and the reliability and the uniqueness of the sub-information to be signed are guaranteed.
An embodiment of the present application provides a signature information processing apparatus, which is applied to a server, as shown in fig. 3, the signature information processing apparatus 30 may include: a pre-parsing module 301, an adding module 302, and a sending module 303, wherein,
The pre-parsing module 301 is configured to obtain original information to be signed, pre-parse the original information to be signed, generate information to be signed, where the information to be signed conforms to a transaction message format, and the information to be signed includes a first hash value of the information to be signed.
It will be appreciated that the original transaction data may be information of the type of transaction, account number, password, transaction amount, transaction time, transaction serial number, etc. obtained from the bank server.
Optionally, in order to ensure that the transaction data to be confirmed is not tampered and improve the signature efficiency of the terminal, format analysis can be performed on the original transaction data at the server side in advance, optionally, the server side can be an upper computer, the upper computer refers to a computer capable of sending a control command, the computer for providing services can also be referred to as an upper computer, and the terminal can be signature authentication equipment.
The signature authentication equipment needs to communicate with the upper computer, and the signature authentication equipment and the upper computer interact in a command and response mode to cooperatively complete the transaction; specifically, after the upper computer obtains the original transaction data, the original transaction data is pre-parsed to obtain the data to be transacted, wherein the upper computer judges the message format of the original transaction data plaintext when the original transaction data is pre-parsed, and if the message format of the original transaction data plaintext is wrong, namely, the data to be transacted does not accord with the transaction message format, the error information can be returned to the bank server so as to enable the bank server to continue processing.
If the message format of the plaintext of the original transaction data is correct, the original transaction data is not tampered, and the original transaction data can be sent to a terminal such as signature authentication equipment for signature authentication by a user; the upper computer can also calculate a first hash value of the data to be transacted and send the first hash value to the signature authentication equipment for subsequent verification.
It should be noted that, the original information to be signed may also be directly sent to the terminal, the terminal pre-parses the original information to be signed, that is, performs judgment of the message format of the original information to be signed, calculates the first hash value thereof, if the message format is wrong, the message is wrongly and safely withdrawn, and if the message format is correct, the first hash value is cached for subsequent verification. It can be understood that the server, that is, the upper computer, is used for judging the message format and calculating the first hash value, so that the processing efficiency of the signature information can be improved.

Therefore, the transaction data to be confirmed can be subjected to segmentation processing, so that the sub-data to be confirmed generated after segmentation can be completely displayed on the signature authentication device.
It should be noted that, the dividing processing operation of the transaction data to be confirmed may be performed at the signature authentication device or at the upper computer, but in order that the signature authentication device may efficiently process the display situation, the dividing processing is generally performed at the upper computer to generate a plurality of transaction sub-data to be confirmed, and an identifier is added to the plurality of transaction sub-data to be confirmed, where the identifier includes not only which transaction data to be confirmed the transaction sub-data belongs to, but also an identifier number for belonging to the same transaction data to be confirmed.
After the upper computer obtains the identification of the transaction sub-data to be confirmed, the transaction sub-data to be confirmed meeting the preset condition can be sent to the signature authentication equipment according to the identification of the transaction sub-data to be confirmed, so that the signature authentication equipment can display the transaction sub-data to be confirmed meeting the preset condition, and then the user can conduct signature authentication on the displayed transaction sub-data to be confirmed meeting the preset condition, and the transaction is completed.

In order to reduce the workload of the signature authentication device and improve the working efficiency of the signature device, the embodiment also provides an optimized scheme, and the upper computer can actively send the transaction sub-data to be confirmed, which is required to be displayed by the signature authentication device.
Specifically, the upper computer can actively acquire the identifier of the transaction sub-data to be confirmed currently displayed by the signature authentication device, and because the identifier contains the number information, at least one third identifier larger than the identifier number can be confirmed according to the identifier number of the transaction sub-data to be confirmed currently displayed, and then the third transaction sub-data to be confirmed corresponding to the third identifier is sent to the signature authentication device, so that when the signature authentication device needs to display the third transaction sub-data to be confirmed, the identifier can be directly acquired inside the signature authentication device without sending an acquisition request to the upper computer, and the display time is saved.
