A method and system for tamper-proof verification of paper contracts

Abstract

The invention discloses a tamper-proof verification method for a paper contract. The method is implemented based on a system. The system includes an input unit, an OCR identification unit, a storage unit, a reading unit and a verification unit. The method includes the following steps: Step S1 , save the original electronic document of the paper contract in the storage unit; step S2, obtain the scanned copy of the paper contract; step S3, the OCR recognition unit uses OCR recognition technology to perform text recognition on the scanned copy, and save the recognized text information as target file; step S4, the reading unit obtains the original electronic document from the storage unit, then reads the text information of the original electronic document and saves it as a reference file; step S5, the verification unit performs a step-by-step process on the text information in the target file and the reference file Perform a comparison and mark the text in the target file that is different from the reference file. The invention realizes the automatic verification function of the paper contract, and the realization process not only saves time and effort, but also has high inspection efficiency and accurate and reliable inspection results.

Description

technical field [0001] The invention relates to a document verification method, in particular to a paper contract tamper-proof verification method and system. Background technique [0002] In the existing technology, in the process of production and operation, enterprise units often need to sign various contracts with other units. For important contracts, the two parties generally need to negotiate and communicate with each other, and finally the paper version with the seals of both parties shall prevail. . But in fact, the stamping time of both parties is inconsistent, and the other party is often stamped after one party has stamped the seal. When Party A receives the contract that Party B has stamped, in order to avoid the content of the contract being tampered with in advance and cause performance The risk is that manual inspection is generally used to verify whether the content of the contract is consistent with the electronic version that has been agreed in advance.

But in fact, the stamping time of both parties is inconsistent, and the other party is often stamped after one party has stamped the seal. When Party A receives the contract that Party B has stamped, in order to avoid the content of the contract being tampered with in advance and cause performance The risk is that manual inspection is generally used to verify whether the content of the contract is consistent with the electronic version that has been agreed in advance. This process is time-consuming and laborious, and a comprehensive inspection cannot be guaranteed, especially for some contracts with many pages and a large number of clauses. It is difficult to achieve accurate verification, which is not only inefficient, but also affects the signing process
