[0026] Exemplary embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.
[0027] Embodiments of the present disclosure provide a file processing method, an apparatus, an electronic device, and a computer-readable storage medium.
[0028] The file processing method provided by the embodiments of the present disclosure can be executed by an electronic device such as a terminal device or a server. The terminal device can be a vehicle-mounted device, a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. The method can be implemented by a processor calling computer-readable program instructions stored in a memory. Alternatively, the method can be executed by a server.
[0029] Figure 1 A flowchart showing the file processing method provided by the embodiments of the present disclosure is shown. As Figure 1 shown, the file processing method provided by the embodiments of the present disclosure includes step S110.
[0030] In step S110, feature information of the nth registration file in the registration file sequence is obtained, and a registration code of the nth registration file is generated based on the registration code of the (n - 1)th registration file in the registration file sequence, a pre-obtained external registration code, and the feature information of the nth registration file;
[0031] wherein, the registration file sequence includes N registration files, and n is an integer greater than 1 and less than or equal to N.
[0032] For example, in the embodiments of the present disclosure, the registration file sequence can be a set of registration files generated by arranging multiple registration files in a certain order. Among them, the registration file can be an electronic file, specifically referring to all types of files stored on storage media such as a computer, including all binary sequences such as various electronic documents, video data, audio data, executable programs, etc.
[0033] In some possible implementation manners, in step S110, the feature information of the registration file includes, but is not limited to, the hash value of the registration file, and / or the generation time of the registration file, and / or the author of the registration file. That is, the feature information is not limited to the hash value. In some application scenarios with relatively strict requirements, other variables such as the file generation time and the file author can also be combined to generate the feature information.
[0034] In some possible implementation manners, the externally obtained registration code obtained in advance can be a registration code generated according to the signature information of the reviewer, or a registration code generated according to the number of registration file bags included in the registration file sequence and the reviewer information. The externally obtained registration code is used to add external information such as the reviewer-related information to the generated registration code.
[0035] In some possible implementation manners, an encryption algorithm can be used to encrypt the registration code of the (n - 1)-th registration file in the registration file sequence, the externally obtained registration code, and the feature information of the n-th registration file, to obtain the registration code of the n-th registration file.
[0036] In some specific implementation manners, the encryption algorithm can be MD5 (Message-Digest Algorithm).
[0037] MD5 is a widely used cryptographic hash function that can produce a 128-bit (16-byte) hash value, which is used to ensure the integrity and consistency of information transmission.
[0038] Certainly, other encryption algorithms are also within the protection scope of the embodiments of the present disclosure.
[0039] In some possible implementation manners, the n-th registration file can be any one of the 2nd to the N-th registration files in the registration file sequence. In the registration file sequence, there can be multiple registration files that generate the registration code of this registration file according to the registration code of the previous registration file, the feature information of this registration file, and the externally obtained registration code.
[0040] In some possible implementation manners, other registration files in the registration file sequence can use other methods to obtain the corresponding registration code.
[0041] In some possible implementation manners, the 1st registration file in the registration file sequence adopts a randomly generated GUID (Globally Unique Identifier) value, and uses an encryption algorithm with the feature information of the 1st registration file to generate the registration code corresponding to the 1st registration file.
[0042] In the document processing method provided by the embodiments of the present disclosure, a registration code is formed by registering a registration document, and the registration code corresponding to each registration document is associated with the registration code of the previous registration document. Therefore, any registration document in the registration document sequence cannot be tampered with, otherwise it will cause the logical verification of the registration code of the entire registration document sequence to fail, thereby achieving the purpose of verifying whether the registered registration document has been tampered with; in addition, when registering a document, generating a registration code does not require extracting the specific content of the registration document, which can ensure the security of the registration document.
[0043] The following specifically introduces the document processing method provided by the embodiments of the present disclosure.
[0044] As described above, the external registration code can be a registration code generated based on the signature information of the reviewer, or a registration code generated based on the number of registration document bags included in the registration document sequence and the reviewer information.
[0045] Figure 2 The flowchart shows an implementation method for generating an external registration code in the case where the external registration code is a registration code generated based on the signature information of the reviewer, as Figure 2 shown, it may include step S210.
[0046] In step S210, an external registration code is generated based on the registration code of the (n - 1)th registration document in the registration document sequence and the signature information of the reviewer.
[0047] In some possible implementation manners, in step S210, the signature information of the reviewer may be information generated based on the signature of the management personnel (i.e., the reviewer) who registers the registration document. For example, the signature of the reviewer is converted into a picture, and the features of the picture are obtained as the signature information of the reviewer.
[0048] Generating an external registration code through the signature information of the reviewer and generating the registration code of the nth registration document based on the external registration code can add a human intervention trace to the registration code. On the one hand, it can increase the complexity of the registration code, and on the other hand, it can also lock the registration code of the current registration document. As long as the registration code and the document of this registration document have not been tampered with, then the registration code of this registration document can be used to verify whether the registration codes of the registration documents before this registration document in the registration document sequence have been changed.
[0049] In some possible implementation manners, an external registration code and the registration code of the nth registration document can be generated by generating a file from the signature of the reviewer and archiving the file.
[0050] Figure 3 The flowchart shows an implementation method for generating an external registration code and generating the registration code of the nth registration document, as Figure 3As shown, generating the external registration code and the registration code of the nth registration file may include steps S310, S320, S330, and S340.
[0051] In step S310, the registration code of the (n - 1)th registration file in the registration file sequence is displayed on the interaction device for the reviewer to input the reviewer's signature information on the interaction device, and an audit electronic file is generated based on the reviewer's signature information.
[0052] In step S320, the feature information of the audit electronic file is obtained, and the feature information of the audit electronic file is used as the external registration code.
[0053] In step S330, the registration code of the audit electronic file is generated according to the registration code of the (n - 1)th registration file in the registration file sequence and the external registration code.
[0054] In step S340, the registration code of the nth registration file is generated according to the registration code of the audit electronic file and the feature information of the nth registration file.
[0055] In some possible implementation manners, in step S310, the interaction device may be a handwriting board or other devices that can allow the reviewer to input the reviewer's signature.
[0056] In some possible implementation manners, the registration code of the (n - 1)th registration file in the registration file sequence may be displayed on an interaction device such as a handwriting board, and the reviewer reviews the registration code through the handwriting board and forms an audit electronic file with a signature.
[0057] In some possible implementation manners, in step S320, obtaining the feature information of the audit electronic file may include but is not limited to the hash value of the audit electronic file, and / or the generation time of the audit electronic file, and / or the reviewer information. That is, the feature information is not limited to the hash value. In some application scenarios with relatively strict requirements, other variables such as the generation time of the audit electronic file and the reviewer information may also be combined to generate the feature information.
[0058] In some possible implementation manners, in step S330, the registration code of the audit electronic file may be obtained in the same way as obtaining the registration code of the registration files in the registration file sequence, that is, the registration code of the audit electronic file is generated according to the registration code of the (n - 1)th registration file and the feature information of the audit electronic file.
[0059] In some possible implementation manners, in step S340, the audit electronic file may be used as the registration file before the nth registration file, and the registration code of the nth registration file is generated according to the registration code of the audit electronic file and the feature information of the nth registration file.
[0060] Therefore, in some possible implementation manners, the reviewed electronic file can be archived as a registration file included in the registration file sequence, that is to say, the reviewed electronic file can be inserted into the registration file sequence. Specifically, the reviewed electronic file can be inserted between the (n - 1)th registration file and the nth registration file. That is to say, the reviewed electronic file becomes the new nth registration file, and the file serial numbers corresponding to the original nth registration file and the registration files after the nth registration file are all incremented by 1.
[0061] As described above, in some possible implementation manners, an external registration code can be generated according to the number of registration files in the registration file sequence and the reviewer information.
[0062] Figure 4 The flowchart shows an implementation manner of generating an external registration code according to the number of registration files in the registration file sequence and the reviewer information and generating a registration file registration code according to the external registration code, as Figure 4 shown, which may include step S410, step S420, and step S430.
[0063] In step S410, an external registration code is generated according to the number of registration files in the registration file sequence and the reviewer information;
[0064] In step S420, an insertion registration code is generated according to the registration code of the (n - 1)th registration file in the registration file sequence and the external registration code;
[0065] In step S430, the registration code of the nth registration file is generated according to the insertion registration code and the feature information of the nth registration file.
[0066] In some possible implementation manners, in step S410, a string code can be generated as the external registration code according to the number of registration files in the registration file sequence and the reviewer information by using a certain algorithm. The specific process of generating the external registration code can be implemented by a dedicated software.
[0067] In some possible implementation manners, in step S420 and step S430, an encryption algorithm is used to generate an insertion registration code according to the registration code of the (n - 1)th registration file and the external registration code, and an encryption algorithm is used to generate the registration code of the nth registration file according to the insertion registration code and the feature information of the nth registration file.
[0068] Among them, the encryption algorithm can be the MD5 algorithm.
[0069] On the one hand, the external registration code is used for verifying the legitimacy of the reviewer, and on the other hand, it increases the complexity of the registration code to prevent the registration code from being rewritten.
[0070] As described above, in some possible implementation manners, other registration documents in the registration document sequence may use other methods to obtain corresponding registration codes.
[0071] Figure 5 The flowchart shows an implementation manner of obtaining the registration code of other registration documents. As Figure 5 shown, obtaining the registration code of other registration documents may include step S510.
[0072] In step S510, obtain the feature information of the m-th registration document in the registration document sequence, and generate the registration code of the m-th registration document according to the registration code of the (m - 1)-th registration document in the registration document sequence and the feature information of the m-th registration document;
[0073] where m is an integer greater than 1 and less than N, and the values of m and n are different.
[0074] In some possible implementation manners, in step S510, the feature information of the registration document may also include but is not limited to the hash value of the registration document, and / or the generation time of the registration document, and / or the author of the registration document. That is, the feature information is not limited to the hash value. In some application scenarios with relatively strict requirements, other variables such as the file generation time and the file author may also be combined to generate the feature information.
[0075] In some possible implementation manners, an encryption algorithm may also be used to encrypt the registration code of the (m - 1)-th registration document in the registration document sequence and the feature information of the m-th registration document to obtain the registration code of the n-th registration document. In some specific implementation manners, the encryption algorithm may also be MD5.
[0076] That is to say, among multiple registration documents in the registration document sequence, multiple registration documents may use external registration codes to obtain corresponding registration codes, and multiple registration documents may also not use external registration codes to obtain corresponding registration codes.
[0077] In some possible implementation manners, the registration codes of all registration documents included in the registration document sequence may be used to generate a registration data chain in the order of the registration documents.
[0078] The generated registration data is a data chain that is connected before and after and can be used for mutual verification. If any registration code in the registration data chain is changed, it will cause the logical verification of the registration data chain to become invalid, thereby helping to determine whether the registration code of the registration document has been modified.
[0079] In some possible implementation manners, the registration code of the review electronic file generated during the generation of the registration code and / or the inserted registration code can be inserted into the registration data chain to increase the complexity of the registration data chain. Specifically, it can be inserted between the registration code corresponding to the nth registration file and the registration code corresponding to the (n + 1)th registration file.
[0080] By inserting the registration code of the review electronic file and / or the inserted registration code into the registration data chain, external interference information can be added to the registration data chain to lock the registration data chain, so as to prevent the occurrence of a security accident where after a certain registration file is artificially tampered with, a new registration data chain is generated again through calculation to prove the validity of the tampered file.
[0081] In some possible implementation manners, after the registration files in the registration file sequence are archived, if it is desired to verify whether the registration file l (l is an integer greater than 1 and less than or equal to N) in the registration file sequence has been tampered with, the feature information of the lth registration file in the registration file sequence is obtained, and according to the registration data chain, the registration code of the (l - 1)th registration file in the registration file sequence and the registration code of the lth registration file in the registration file sequence are obtained.
[0082] In the case where the external registration code does not participate in the generation of the registration code of the lth registration file, the verification code of the lth registration file is generated according to the registration code of the (l - 1)th registration file in the registration file sequence and the feature information of the lth registration file; the verification code of the lth registration file is compared with the registration code of the lth registration file to determine whether the registration file in the registration file sequence has been tampered with.
[0083] In the case where the external registration code participates in the generation of the registration code of the lth registration file, the verification code of the lth registration file is generated according to the reviewer signature information or reviewer information, the registration code of the (l - 1)th registration file in the registration file sequence, and the feature information of the lth registration file; the verification code of the lth registration file is compared with the registration code of the lth registration file to determine whether the registration file in the registration file sequence has been tampered with.
[0084] In some possible implementation manners, if the verification code is consistent with the registration code, it indicates that the registration file l has not been tampered with.
[0085] Next, a specific embodiment is used to specifically introduce the file processing method provided by the embodiments of the present disclosure.
[0086] Figure 6 The process schematic diagram of a specific embodiment of the file processing method provided by the embodiments of the present disclosure is shown. As Figure 6 shown, the registration file 1, registration file 2, registration file 3... registration file N are arranged in sequence to form a registration file sequence.
[0087] Generate a randomly generated GUID random code R1, and use the hash value H1 of registration file 1. Use the formula V1 = F(R1, H1) to obtain the registration code V1 of registration file 1.
[0088] Use the registration code V1 and the hash value H2 of registration file 2. Use the formula V2 = F(V1, H1) to obtain the registration code V2 of registration file 2.
[0089] Use the registration code V2 and the hash value H3 of registration file 3. Use the formula V3 = F(V2, H3) to obtain the registration code V3 of registration file 3.
[0090] And so on. Use the registration code V(n - 1) of registration file n - 1 and the hash value H(n) of registration file n. Use the formula V(n) = F[V(n - 1), H(n)] to obtain the registration code V(n) of registration file n.
[0091] Where F is the algorithm function of the MD5 algorithm. The hash value H(n) of registration file n can be calculated using the formula H(n) = HashFile[File(n)]. HashFile is the function for calculating the file hash value, and File(n) is the file content of registration file n.
[0092] During the registration and archiving of the registration files, the auditor can randomly add artificial traces to the registration code of the registration file to increase the security of the registration code.
[0093] As Figure 6 shown, after obtaining the registration code of registration file m (1 < m < N), the generated registration code V(m) of the mth file can be displayed on the tablet. After the auditor signs on the tablet, an audited electronic file with a signature is formed, or the registration code of registration file m is printed out, and then scanned into an audited electronic file after being signed by the auditor.
[0094] Archive the audited electronic file as the (m + 1)th file in the registration file sequence, that is, use the formula V(S) = F[V(m), H(S)] to calculate the registration code of the audited electronic file, where H(S) is the hash value of the audited electronic file.
[0095] For the registration files after the audited electronic file, that is, registration file m + 1, use the formula V(m + 1) = F[V(S), H(m + 1)] to calculate. The calculation method for calculating the registration code of the subsequent registration files does not change.
[0096] After obtaining the registration code of the registration document q (1 < q < N), the authorization code Kq (i.e., the external registration code) can be generated using a certain algorithm based on the number of registration documents included in the registration document sequence and the reviewer information. The external voucher lock code Lq (i.e., the inserted registration code) is generated using the authorization code Kq and the registration code of the registration document q. Specifically, the external voucher lock code Lq can be calculated using the formula Lq = F[V(q), Kq], and the registration code of the registration document q + 1 is generated based on the hash value of the registration document q + 1, that is, the registration code of the registration document q + 1 is calculated using the formula V(q + 1) = F[Lq, H(q + 1)].
[0097] After completing the archiving of the registration documents and the review electronic documents (i.e., registration document 1, registration document 2, registration document 3... registration document m, review electronic document, registration document m + 1, registration document m + 2... registration document N) and generating the registration code V(N) of the registration document N, the registration codes of each registration document, the registration code of the review electronic document, and the external voucher lock code are saved as a registration data chain in the generation order, that is, V1, V2, V3... V(m), V(S), V(m + 1), V(m + 2)... V(q), Lq, V(q + 1), V(q + 2)... V(N).
[0098] When anti-tampering verification of the registration document is required, only the registration code S of the file to be verified and the file to be verified need to be provided.
[0099] Specifically, obtain the registration code of the registration document ranked one position before the file to be verified and the hash value of the current file to be verified, and then calculate the verification code of the file to be verified through the algorithm used in the above process and compare it with the registration code of the file to be verified recorded in the system.
[0100] When the registration code found in the registration data chain is consistent with the calculated verification code, it indicates that the file to be verified provided is consistent with the content of the registered registration document archived and has not been tampered with; otherwise, it indicates that the file to be verified provided is inconsistent with the content of the registered registration document archived and has been tampered with.
[0101] Of course, in some occasions with stricter verification requirements, information for registration verification (including but not limited to) the generation time T of the registration document, the author W of the registration document, etc. can also be added to the calculation variables, that is:
[0102] V(n) = F[V(n - 1), H(n), T(n), W(n)……];
[0103] And so on,[[]]END]]
[0104] V(S) = F[V(m), H(S), T(S), W(S)……], where T(S) is the generation time of the reviewed electronic document, and W(S) is the reviewer information;
[0105] V(m + 1) = F[V(S), H(m + 1), T(m + 1), W(m + 1)……];
[0106] Lq = F[V(q), Kq]; V(q + 1) = F[Lq, H(q + 1), T(q + 1), W(q + 1)……];
[0107] ……
[0108] V(1) = F[R1, H(1), T(1), W(1)……].
[0109] Based on the same principle as the method shown in Figure 1 Figure Figure 7 shows a schematic structural diagram of a file processing device provided by an embodiment of the present disclosure. As Figure 7 shown, the file processing device 70 may include:

[0111] where the registration file sequence includes N registration files, and n is an integer greater than 1 and less than or equal to N.
[0112] In the file processing device provided by the embodiment of the present disclosure, by registering the registration file to form a registration code, the registration code corresponding to each registration file is associated with the registration code of the previous registration file. Therefore, any registration file in the registration file sequence cannot be tampered with, otherwise it will cause the logical verification timeliness of the registration codes of the entire registration file sequence, thereby achieving the purpose of verifying whether the registered registration file has been tampered with; in addition, when registering the file, generating the registration code does not require extracting the specific content of the registration file, which can ensure the security of the registration file.
[0113] In some possible implementation manners, the file processing device 70 further includes: a second registration module, which obtains the feature information of the mth registration file in the registration file sequence, and generates the registration code of the mth registration file according to the registration code of the (m - 1)th registration file in the registration file sequence and the feature information of the mth registration file; where m is an integer greater than 1 and less than N, and the values of m and n are different.

[0116] In some possible implementations, the file processing device 70 further includes: a registration code generation module, configured to generate an external registration code according to the registration code of the (n - 1)-th registration file in the registration file sequence and the reviewer's signature information.
