Embodiment Construction

[0015] The present invention will be further described below by specific embodiment:

[0016] 1) Suppose a company has a construction contract management system, hereinafter referred to as the contract system. All sales contracts of the company need to be registered through the system, and the contracts can only be printed after being approved by the company leaders;

[0017] 2) The paper contract printed by the salesperson is handed over to the parties to the contract to sign and seal it, and then both parties keep it separately;

[0018] 3) The office has full-time staff who are responsible for keeping and archiving the completed contracts. Every contract received needs to be carefully screened, which is time-consuming, labor-intensive and error-prone. A simple and effective contract verification method is needed to ensure the authenticity of the received contracts Credible and consistent with the content registered in the contract system;

[0019] 4) In order to meet the ...

Abstract

The invention relates to a contract anti-counterfeiting watermark and mobile fingerprint recognition method, and relates to the field of contract printing and mobile fingerprint recognition. The method comprises the steps of drawing a watermark pattern having discretely distributed irregular shapes by utilization of random variables, equally dividing acquired fingerprint characteristic values of 256 bytes into 8 segments, performing multiple encryption on the random variables and contract key information points by using the fingerprint characteristic values serving as secret key Key values of AES encryption, and performing SHA-1 encryption to prevent the information from being tampered. The encrypted information is printed on contract texts in a two-dimensional code manner, the two-dimensional code and the watermark pattern are commonly used to guarantee anti-counterfeiting of the contract texts, the real information and watermark pattern of the contract can be rapidly restored by scanning the two-dimensional code and acquiring fingerprint information by using a cellphone App, the problem that in the prior art, a complex professional identification method is required for the text contract is solved, safety management of the contract texts is improved, and contract authenticity identification capability is enhanced.

Description

technical field [0001] The invention relates to a contract anti-counterfeiting method based on mobile terminal fingerprint identification, and relates to the fields of contract printing and mobile fingerprint identification. Background technique [0002] At present, contract anti-counterfeiting technology generally uses anti-counterfeiting official seals, anti-counterfeiting paper, anti-counterfeiting digital blind watermarks and other methods to add security to contracts. Such methods are costly and require professional identification devices or professionals for anti-counterfeiting identification. [0003] Smartphones with fingerprint functions are rapidly popularizing. Due to the security, reliability and convenience of fingerprint identification and authentication technology, mobile application contract anti-counterfeiting App developed by using mobile phone fingerprints can conveniently and effectively identify and authenticate contract texts, allowing users to Verify t...
