Embodiment Construction

[0044] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0045] like figure 1 As shown, the present invention provides a kind of authentication method based on documents, and the method comprises the following steps:

[0046] Step 1, the document issuer generates a document identifier, and sends the document identifier to the key generation center, wherein the document identifier includes unique authentication information of the document issuer.

[0047] Preferably, the unique identification information of the document issuer includes the code and / or code of the document issuer. For example, the identification information of the document issuer may be the name or abbreviation of the document issuer, or the digital code of the document issuer, or a combination of the two, and other forms of information may also be used .

[0048] The identification of the document may be in the form of identi...

Abstract

The invention provides a document identification method and system based on identity cryptograph. The document identification system based on identity cryptograph includes a cryptograph generation center, a document issuing party and a document verification party. The document identification method based on identity cryptograph effectively realizes anti-counterfeiting identification of a large number of objects, such as documents, by means of an identity cryptograph algorithm. Different from the prior art in which public and private key pairs are distributed to each document issuing party andthe each document issuing party uses the own private key to make a signature on each document, the technical scheme of the document identification method and system based on identity cryptograph generates the private key of the document by using the identification cryptograph algorithm according to the identity of each document and sends the private key to the document issuing party, and the document issuing party makes a signature by using the identity cryptograph algorithm according to the private key of the document so as to generate an anti-counterfeit document and when the signature is identified, the document identity can be directly used as the signature public key of the document for identification.

Description

technical field [0001] The invention relates to the technical field of information security and computer application, in particular to a method and system for identifying documents based on identification codes. Background technique [0002] Documents play a very important role in business and trade activities. Some lawbreakers forge documents to make profits, or use forged documents to commit fraud and fraud, which brings great economic losses to the country, enterprises or individuals. Therefore, the user of the document and the supervisory department need a complete document anti-counterfeiting identification method to judge the authenticity of the document and ensure the safety of the use of the document. [0003] Commonly used document anti-counterfeiting identification technologies mainly include anti-counterfeiting printing technology and encryption technology. Anti-counterfeiting printing technology can only be applied to paper documents, while encryption technolog...
