Document encryption method and device, document decryption method and device, electronic equipment and medium

Abstract

The invention relates to a document encryption method, a document decryption method, a document encryption device, a document decryption device, electronic equipment and a non-temporary computer readable storage medium. The document encryption method comprises: obtaining a to-be-encrypted document and a plurality of content characters of the to-be-encrypted document, obtaining a content coding sequence of the to-be-encrypted document, acquiring an encrypted iris image, obtaining a key vector of the to-be-encrypted document through feature extraction, and obtaining an encrypted document based on the content coding sequence and the key vector. The document decryption method comprises: obtaining an encrypted document, obtaining a decrypted iris image, and obtaining a decryption vector according to the decrypted iris image so as to decrypt the encrypted document. According to the method provided by the invention, the characteristics of uniqueness, high stability, strong anti-counterfeitingproperty and the like of the iris are utilized, and the content of the document to be encrypted is combined to encrypt the document to be encrypted. Therefore, the decrypted and encrypted document has uniqueness, the possibility of document content leakage is reduced, and the information security of the encrypted document can be effectively guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of data information processing, and in particular to a document encryption method, a document decryption method, a document encryption device, a document decryption device, electronic equipment, and a non-transitory computer-readable storage medium. Background technique [0002] In related technologies, with the continuous development of electronic information technology, most information is transmitted in the form of electronic documents. In order to ensure the security of document information, the encryption key of the document is often created in the form of typing, and the document that needs to be kept secret is encrypted. But with this type of encryption, decryption is possible as long as you have the correct decryption key. There is no way to determine whether the person who decrypted the document was a genuine viewer of the document or someone with malicious intent. A malicious person is a...
