Problems solved by technology

However, this method of embedding a specific pattern in a picture has such problems: the content of the embedded pattern is not related to the content of the protected picture, and the embedded pattern is easy to be forged
However, this method of embedding an anti-counterfeiting digital watermark in a picture is limited by the picture format and content, and the digital watermark embedding capacity is not high

Abstract

The invention relates to methods and systems for generating and checking an electronic note with an anti-counterfeiting two-dimension code. The method for generating the electronic note with the anti-counterfeiting two-dimension code comprises the following steps that: an original electronic note picture is read, and a temporary electronic note picture with a defined two-dimension code embedding region is generated; for the temporary electronic note picture, an information abstract algorithm is utilized for calculating abstract data, and in addition, the obtained abstract data is encrypted for generating the anti-counterfeiting two-dimension code; and the anti-counterfeiting two-dimension code is embedded into the two-dimension code embedding region of the original electronic note picture, and the electronic note with the anti-counterfeiting two-dimension code is obtained. The methods and the systems provided by the invention can be used for effectively preventing the tampering and the counterfeiting of the electronic note, and in addition, the diversity and the practicability of the electronic note can be greatly improved.

Description

technical field [0001] The present invention relates to information security technology, and more specifically relates to a data processing technology for data processing images with two-dimensional codes. Background technique [0002] Electronic bills, also known as electronic commercial bills, are gradually produced and developed with the development of the economy. It is based on the functions of paper bills on payment, use, settlement and financing, and uses digital networks to transfer money from one account to another. An account that uses electronic impulses instead of paper for the transfer and storage of funds. It is based on computers and modern communication technology networks, stores capital information in the computer system in the form of data messages, and realizes the function of traditional paper bills in the form of electronic information transmission that is invisible and inaccessible through the Internet. The so-called "data message" refers to informati...
