Wherein:
the attribute generation module 11 is used for extracting attribute information of the original document and associating the attribute information to the original document. The attribute information here includes information on the document such as operator information for operating on the document, document operation time, document operation address, and the like. Since the processing personnel, address, time, etc. for generating each document are different, i.e. each document has its own unique attribute information, each document corresponds to an attribute information that is unique from other documents. Furthermore, the authenticity of the document can be verified according to the unique attribute information of the document.
The attribute generation module 11 uploads the original document and the extracted attribute information to the server credentialing module 12. The server certificate storage module 12 stores the original document and the attribute information corresponding to the original document to realize certificate storage. The original document stored by the server storing module 12 and the corresponding attribute information thereof are both evidences that the printed paper document can be distinguished to be true or false.
The network address generation module 13 is configured to generate a network address, through which the original document and its corresponding attribute information stored in the server authentication module 12 can be accessed. That is, the network address generation module 13 generates each network address with which a unique original document and its corresponding attribute information are associated, and the associated original document and its corresponding attribute information can be found by the network address.
The first bitmap encoding module 14 is configured to generate a first bitmap according to the network address. That is, the corresponding network address can be identified through the first bitmap, and the original document associated with the network address and the corresponding attribute information can be found.
The second bitmap encoding module 15 is configured to process the first bitmap according to the ciphertext information to obtain a second bitmap. The first bitmap can be encrypted in such a way, and the generated second bitmap has encryption property, so that the attribute information of the document is safer.
In the present invention, the first bitmap and the second bitmap generated by the first bitmap encoding module 14 and the second bitmap encoding module 15 may be two-dimensional code, three-dimensional code, or customized bitmap.
The data synthesis module 16 is used for embedding the second bitmap into the original document to generate a printed document. The server authentication module 12 saves the print document. The printed document is operable to be printed as a paper file. The second dot matrix diagram contained in the printed paper file can verify the authenticity of the paper file.
In a preferred embodiment, the system 100 for tracing the printed document against forgery further includes: an original document storage module 10 and a printed document storage module 17. The original document storage module 10 is used for storing original documents, and the attribute generation module 11 receives the original documents stored by the original document storage module 10.

The preprocessing module 19 is used for preprocessing the image information to obtain a bitmap to be recognized and a document to be recognized.
The first bitmap identification module 20 is configured to identify a bitmap to be identified, so as to identify a network address to be identified.
The second bitmap identification module 21 is configured to identify a bitmap to be identified, so as to identify ciphertext information to be identified.
Further, the system 100 for anti-counterfeiting tracing of printed documents further comprises: a login module 22, a verification module 23 and a result output module 24. The login module 22 is configured to access the server authentication module 12 according to the network address to be identified to obtain the original document stored in the server authentication module 12. The checking module 23 is used for comparing the document to be identified and the original document to distinguish whether the document to be identified and the original document are identical, i.e. whether the documents are the same document. By the method, the anti-counterfeiting tracing can be performed on the printed paper file. The result output module 24 is configured to output a comparison result, that is, the comparison result is output for the user to review.
Further, the system 100 for tracing the printed document against forgery further comprises: a key storage module 25 and a ciphertext storage module 26. The key storage module 25 is used for storing the lattice key and the lattice scrambling key. The ciphertext storage module 26 is configured to store ciphertext information.
The second bitmap encoding module 15 obtains the dot matrix key, the dot matrix scrambling key, and the ciphertext information from the key storage module 25 and the ciphertext storage module 26, and processes the first bitmap according to the dot matrix key, the dot matrix scrambling key, and the ciphertext information to obtain a second bitmap.
Otherwise, the second bitmap is processed by the second bitmap identification module 21 according to the dot matrix key and the dot matrix scrambling key obtained from the key storage module 25 to obtain the ciphertext information.
The operation method of the above-mentioned anti-counterfeiting tracing system 100 for printed documents is as follows:
attribute information of the original document is acquired by the attribute generation module 11 and attributes are associated to the original document.
The original document and its corresponding attribute information are saved by the server attestation module 12. The original document and the corresponding attribute information are verification information for verifying the authenticity of the document, so that the verification information can be stored.
The network address is generated by the network address generating module 13, and the original document and its corresponding attribute information stored in the server authentication module 12 can be accessed by the network address.
And generating a first bitmap according to the network address through the first bitmap encoding module 14.
And processing the first bitmap through the second bitmap coding module 15 according to the ciphertext information to obtain a second bitmap.
The second bitmap is embedded into the original document by the data synthesis module 16 to generate a printed document.
The original document and the corresponding attribute information can be associated with the printed document as the verification information through the method, and the document is encrypted by setting the ciphertext information, so that the anti-counterfeiting tracing of the paper document printed by the printed document can be realized through the second dot matrix.
Further, the operation method of the printed document anti-counterfeiting tracing system 100 further includes:
image information of the paper document to be recognized is acquired by the image acquisition module 18.
The image information is preprocessed by the preprocessing module 19 to obtain a bitmap to be recognized and a document to be recognized.
The first bitmap identification module 20 identifies the bitmap to be identified to obtain the network address to be identified.
And identifying the bitmap to be identified through the second bitmap identification module 21 to obtain ciphertext information to be identified.
Further, the original document stored in the server authentication module 12 is obtained by accessing the server authentication module 12 through the login module 22 according to the network address to be identified. The document to be recognized and the original document are compared by the verification module 23 to discriminate whether the document to be recognized and the original document are the same document.
As an implementation manner, the second bitmap encoding module receives a dot matrix key, a dot matrix scrambling key and ciphertext information input by a user to process the first bitmap to obtain a second bitmap. Otherwise, when the user needs to obtain the ciphertext information, the user inputs the dot matrix key and the dot matrix scrambling key again, and the second dot matrix pattern recognition module receives the dot matrix key and the dot matrix scrambling key input by the user and recognizes the second dot matrix pattern to obtain the ciphertext information to be recognized. And then whether the obtained ciphertext information to be identified is the same as the ciphertext information set by the second dot-matrix coding module before is judged manually so as to verify the printed paper file, and then whether the paper file is directly printed by the printed document is distinguished, so that the anti-counterfeiting traceability can be carried out on the paper file, and the situation that the paper file directly printed by the printed document is falsified by people is avoided.
As a specific embodiment, the key storage module 25 stores a lattice key and a lattice scrambling key, and the ciphertext storage module 26 stores ciphertext information. The second bitmap encoding module automatically obtains the dot matrix key, the dot matrix scrambling key and the ciphertext information from the key storage module 25 and the ciphertext storage module 26. The second bitmap encoding module 15 processes the first bitmap according to the automatically acquired bitmap key, the bitmap scrambling key and the ciphertext information to obtain a second bitmap. On the contrary, when the user needs to obtain the ciphertext information, the second bitmap identification module 21 processes the second bitmap according to the dot matrix key and the dot matrix scrambling key automatically obtained from the key storage module 25, so as to obtain the ciphertext information. The ciphertext information to be identified and the ciphertext information are compared by the checking module 23 to verify whether the ciphertext information to be identified and the ciphertext information are consistent, that is, whether the document to be identified and the original document are the same document and are falsified or not is distinguished. Through such embodiment, the printed paper file can be verified to judge whether the paper file is directly printed through the printed document, namely, the anti-counterfeiting tracing can be carried out on the paper file, and the situation that the paper file directly printed through the printed document is falsified by people is avoided.
By the mode, the situation that a user needs to actively input the dot matrix key and the dot matrix scrambling key to obtain the ciphertext information can be avoided. The problems that the operation of actively inputting the dot matrix key and the dot matrix scrambling key by a user is complicated, the efficiency is low, and the memory errors of the dot matrix key and the dot matrix scrambling key corresponding to the corresponding ciphertext information can occur are solved.
The original documents in the scheme include WORD documents, EXCEL documents and PDF documents, but are not limited to WORD documents, EXCEL documents and PDF documents, and may also include other forms of documents.
As a specific embodiment, the image acquisition module 18 is a scanner.
As an alternative embodiment, the image capturing module may also be a camera or other device capable of capturing images.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
