Problems solved by technology

[0003] In addition, at present, electronic signatures in paper anti-counterfeiting documents are at risk of being imitated, especially handwritten electronic signatures are easier to be imitated
Therefore, there is such a situation: when the signer of the electronic signature of the paper anti-counterfeiting document faces a paper document signed by himself, due to various reasons, he may not recognize that the paper anti-counterfeiting document is signed by himself , that is, the phenomenon of denial by the signer
However, according to the prior art, there is no objective method to verify whether the paper anti-counterfeiting document is signed by the person himself.

Embodiment 1

[0078] figure 1 It is a schematic flow chart of the method for generating a paper anti-counterfeit document provided in Embodiment 1 of the present invention. Such as figure 1 As shown, the generation method of the paper anti-counterfeiting document comprises the following steps:

[0079] S101. Generate signature evidence information for the signer to sign on the electronic document:

[0080] The signature evidence information of the signer's signature on the electronic document is the information indicating the signing relationship between the signer and the electronic document signed by the signer.

[0081] As a specific embodiment of the present invention, the signature evidence information may be the recording information of the electronic document signed by the signer. For example, the signer can declare when and where a XX document was signed, so as to indicate the signing relationship between the signer and the electronic document. When the signature evidence inform...

Embodiment 2

[0114] It should be noted that the paper anti-counterfeiting document applicable to this identification method is generated using the generation method described in the first embodiment above.

[0115] figure 2 It is a schematic flowchart of a method for identifying paper-based anti-counterfeit documents provided in Embodiment 2 of the present invention. Such as figure 2 As shown, the identification method includes the following steps:

[0116] S201. Convert the paper anti-counterfeiting document into an electronic image file:

[0117] Convert paper anti-counterfeiting documents into electronic image files by means of scanners or photographs. In layman's terms, the paper anti-counterfeiting document is converted from a paper version to an electronic version.

[0118] It should be noted that the information contained in the electronic image file is exactly the same as that contained in the paper anti-counterfeiting document. Since the paper anti-counterfeiting document i...

Embodiment 3

[0147] image 3 It is a schematic flow diagram of the device for generating paper anti-counterfeiting documents provided by Embodiment 3 of the present invention. Such as image 3 As shown, the generating device includes the following units:

[0148] A first generation unit 301, configured to generate signature evidence information for the signer to sign on the electronic document;

[0149] A first loading unit 302, configured to load the signature evidence information into a data storage carrier;

[0150] The output unit 303 is configured to output the signed electronic document to generate a paper anti-counterfeit document, and the paper anti-counterfeit document is attached with the data storage carrier.

[0151] The paper anti-counterfeiting document generated by the first generating unit 301 , the first loading unit 302 and the output unit 303 has the function of preventing repudiation.

[0152] In order to make the generated paper anti-counterfeiting document also ha...

Abstract

The invention provides methods and devices for generating and distinguishing an anti-counterfeiting paper document. In the method for generating the anti-counterfeiting paper document, document information, an electronic signature, an anti-counterfeiting ciphertext, an anti-counterfeiting signature picture and a data storage carrier are bound together, so that the generated anti-counterfeiting paper document has functions of preventing repudiation, preventing tampering and preventing copying. In addition, the distinguishing method can distinguish whether the anti-counterfeiting paper document is signed by a signer, tampered and copied; further, the anti-counterfeiting paper document can be comprehensively protected, and the safety of the anti-counterfeiting paper document is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for generating and identifying paper-based anti-counterfeiting documents. Background technique [0002] The security of electronic documents can be guaranteed by technologies such as digital signatures, but when electronic documents are output as paper documents, the digital signature data with anti-counterfeiting function will disappear. In order to ensure the security of paper documents, it is necessary to carry out anti-counterfeiting protection on paper documents. [0003] In addition, at present, electronic signatures in paper anti-counterfeiting documents are at risk of being imitated, especially handwritten electronic signatures are easier to be imitated. Therefore, there is such a situation: when the signer of the electronic signature of the paper anti-counterfeiting document faces a paper document signed by himself, due to various reasons, he may ...
