Data encryption and decryption method, device and electronic equipment

Abstract

Data encryption and decryption methods and apparatuses, an electronic device and a readable storage medium relate to the field of data processing. The data encryption method comprises: obtaining an iris image of a user; generating an iris template according to the iris image; generating a data key according to the iris template, and encrypting the iris template; and encrypting an obtained file to be encrypted according to the data key. As an iris template can be generated according to an iris image, a different data key can be generated for each different file to be encrypted according to a different iris template generated each time. Therefore, the security of data keys and the security of data are improved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data encryption and decryption method, device and electronic equipment. Background technique [0002] With the development of science and technology, computers, mobile phones, radio frequency cards and other storage media are used more and more widely, in which a large number of electronic documents of different types and involving highly confidential information are stored. Once this information is illegally stolen, it will cause immeasurable losses. , and the current common practice is to use various document security software to encrypt data. The mainstream encryption systems in the industry, such as PGP and True Crypt, use a mixture of multiple encryption algorithms to improve security, but these encryption systems have a significant defect, that is, if the key is forgotten or lost, the Encrypted files cannot be decrypted normally and become obsolete data that cannot...

Problems solved by technology

The mainstream encryption systems in the industry, such as PGP and True Crypt, use a mixture of multiple encryption algorithms to improve security, but these encryption systems have a significant defect, that is, if the key is forgotten or lost, the Encrypted files cannot be decrypted normally and become obsolete data and cannot be used

And in the prior art, the iris image is used to encrypt the file, and the encryption key generated by this method has the same identity. Therefore, the security of the key generated by this method is relatively poor, and the security of the data cannot be truly guaranteed.
