Embodiment 1

[0015] Take the example of contract documents as paper documents. A method for preventing document contents / seals from being forged and tampered with, comprising the following steps:

[0016] a. Information collection: when editing a contract document, important words and digital information constitute the first collection information, and the seal position image information on the contract document constitutes the second collection information, and the seal image information on the contract document and the system reserved original The comparison information between the seal information constitutes the third collected information, and then the first, second and third collected information are processed and transformed into information of a matrix two-dimensional code, and the matrix two-dimensional code is a PDF417 two-dimensional code.

[0017] b. Information copy: print the above-mentioned matrix QR code on the contract document.

[0018] c. Information comparison: scan an...

Embodiment 2

[0021] Take a bank check as an example of a paper document. A method for preventing document contents / seals from being forged and tampered with, comprising the following steps:

[0022] a. Information collection: When editing bank checks, important words and numbers are used to form the first collection information, and the image information of the seal position on the bank check is used to form the second collection information. The image information of the seal on the bank check and the system reserved original information The comparison information between the seal information constitutes the third collection information, and then the first, second and third collection information (such as check code, amount, company name, bank system seal and seal image, etc.) are processed and transformed into a The matrix QR code information, the matrix QR code is a PDF417 QR code.

[0023] b. Copy information: print the above matrix QR code on the bank check.

[0024] c. Information c...

Abstract

A method for preventing file content / stamp from being forged and tampered comprises the following steps: when a paper file is edited, defining important words and numerical information to be first pick-up information, defining stamp position image information on the paper file to be second pick-up information, defining comparison information between the stamp image information on the paper file and the pre-remained original stamp information of a system to be third pick-up information, and transforming the first pick-up information, the second pick-up information and the third pick-up information to be a matrix two-dimensional code information via treatment; printing the matrix two-dimensional code on the paper file; and interpreting the first pick-up information, the second pick-up information and the third pick-up information in the matrix two-dimensional code after scanning by a terminal, and then comparing the interpreted first pick-up information, second pick-up information and third pick-up information with important words, numbers, stamping position and stamp image information in the paper file so as to quickly identify the authenticity. By the method, the possibility of forging and tampering file content and stamp is effectively avoided, the extracted information is targeted and little, the treating process is high, and the method is convenient to transmit and store.

Description

technical field [0001] The invention relates to barcode science and anti-counterfeiting technology, in particular to a method for preventing document contents / seals from being forged and tampered with. Background technique [0002] At present, in daily life, it is necessary to encrypt documents, certificates, bills, contracts, checks, vouchers, etc. that are encrypted with various seals. These stamped documents, certificates, bills, contracts, checks, and vouchers appear in large numbers in our work and life. Due to the large amount of information, it is impossible to build an information database and compare them one by one, resulting in the possibility of forgery and tampering of documents, certificates, bills, contracts, checks, vouchers and seals, disrupting social order and financial order. [0003] Take a commercial contract as an example. After the two parties sign and seal the contract, if a dispute arises during the execution process, malicious tampering of the con...
