Abstract

The invention discloses a image counterfeit deterrence method based on the chaotic feature, comprising: first, by the chaotic mapping system, using the information needed keep secret and counterfeit deterrence to generate the chaotic sequence which is used to encode the information, then, printing the encoded information to the two-dimension bar code image according to the PDF417 bar code; collecting the two-dimension bar code image by the scanner, and operating the preprocessing of image segmentation, filtration, geometric correction and stratified on collected image, then decoding the bar code according to the decoding rule of national standard PDF417 bar code to attain the chaotic encoded information carried by bar code image. The invention fully utilizes the features of chaotic system and two-dimension bar code technique which are combined for image counterfeit deterrence. The invention has the characters as strong secret-keeping property and large information carried, while it can recognize automatically.

Description

technical field

[0001] The invention belongs to the technical fields of information security and information hiding, and relates to an image anti-counterfeiting method, in particular to an image anti-counterfeiting method based on chaotic characteristics. Background technique

[0002] Information security and information hiding are currently hot issues that people are concerned about. People often need to hide some key information and take it out conveniently when needed, so as to realize information hiding and anti-counterfeiting. Cryptography is the core of information security. To ensure the confidentiality of information, using passwords to encrypt it is the most effective way. Encryption is one of the most important technical measures to ensure information security. It can not only be used to protect the confidentiality of information, but also can be used to detect data integrity, etc., and has a wide range of uses. However, with the development of cryptography and th...
