Encryption and decryption method based on multi-biometric feature fusion and application

Abstract

The invention discloses an encryption and decryption method based on multi-biometric feature fusion. The encryption method comprises the following steps that various biometric feature data is combinedwith a password through a Hash hash function to generate an encryption key; the encryption key in combination with the private data may encrypt the private data. In the application of an encryption and decryption method based on multi-biometric feature fusion,the encryption and decryption method based on multi-biometric feature fusion is applied to network transmission of streaming media electronic files such as photos and videos. On the basis of original information encryption, a security authentication technology with biological characteristics such as irises, fingerprints and finger veinsfused with passwords is added; the technical difficulty of information encryption and decryption is greatly improved, the secret key is more unique, due to the uniqueness of iris, fingerprint and finger vein, the scanning and reading speed is high, and imitation and recognition are not easy, the safety and rapidity of information encryption and decryption are enhanced, and the data transmission encryption and decryption of the camera are safer and more reliable.

Description

technical field [0001] The present invention relates to an encryption and decryption method and application, in particular to an encryption and decryption method and application based on fusion of multiple biological features. Background technique [0002] With the advancement of science and technology and the development of the information age, "video information" as a resource has played a decisive role in today's rapid development of network and information technology. With the rapid popularization of computer networks and the rapid improvement of network performance, With the surge of cloud computing and big data, network video surveillance is showing a vigorous development trend in smart cities, smart transportation, and related enterprises and families with its good technology and cost advantages. A variety of smart camera products for home versions have emerged, which can monitor all aspects of the family at any time, which is convenient for people's lives, but also c...

Problems solved by technology

[0007] In the existing technologies and solutions, most manufacturers adopt back-end storage or cloud platform management. Clients of streaming media products such as audio and video are installed on various client terminals such as computers and mobile phones, and are distributed to multiple people for use. The key is transmitted to the back-end storage or cloud platform through the network, the data is stored centrally, and the key setting is simple. Information data such as images, voices, and videos can be easily cracked through a series of codes, so that the information data is exposed to the network environment, and there is a risk of being hacked.
