Abstract

The invention discloses an image certainty encryption double-blind secrecy matching method and relates to data instability measuring and image matching technology. The image certainty encryption double-blind secrecy matching method can be used for conducting secrecy matching on an image with randomly disordered pixel positions by means of the characteristic that an instability measuring method can be used for measuring the stability of data streams. The image certainty encryption double-blind secrecy matching method has the advantages that the pixel positions of the image are disordered and encrypted, and under the situation that the random number of the positions is unknown, the image cannot be restored and image content cannot be identified; the encrypted image is difficult to decrypt; under the situation that a secret key is known, the image can be easily restored. The image certainty encryption double-blind secrecy matching method has wide application prospects in the fields of identity authentication, information security and the like.

Description

technical field

[0001] The invention relates to data instability measurement and image matching technology, in particular to an image deterministic encryption double-blind secret matching technology method. This technology has broad application prospects in the fields of identity authentication and information security. Background technique

[0002] In the era of big data, data security is a very important issue. Especially after the recent discontinuation of XP service by Microsoft in the United States, hackers may maliciously invade computers and steal various data, which will inevitably cause irreparable losses to the country, enterprises and other departments or individuals. Image is one of the important data types, how to keep its content secret and how to match it under the condition of confidentiality is a very challenging research topic. Based on the research results at home and abroad, at present, image matching and recognition methods can be mainly divided into t...
