Iris dynamic encryption and decryption system and method for electronic document circulation

Abstract

The present invention relates to an iris dynamic encryption and decryption system and method for electronic document flowing. The system is realized in a mode that a user accesses an electronic document flowing server through respective network communication terminal equipment, and the electronic document flowing server comprises an iris service module and an electronic document flowing module. The method disclosed by the present invention comprises the following steps: (1) registering an iris characteristic value of a receiver in advance; (2) encrypting an electronic document; (3) transmitting the electronic document encrypted; (4) receiving the electronic document encrypted; (5) requesting to decrypt the electronic document; (6) acquiring iris characteristic information; (7) extracting an iris characteristic value from the iris characteristic information; (8) comparing the extracted iris characteristic value with the iris characteristic value of the receiver; (9) judging whether the iris characteristic values are matched or not; (10) calling the iris characteristic value to decrypt the electronic document; and (11) finishing the decryption of the electronic document. The system and the method can meet the actual requirement of safely and confidentially flowing the electronic document.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and further relates to an iris dynamic encryption and decryption system and method for electronic document circulation in the technical field of network data communication. The invention utilizes the uniqueness of iris features to provide a system and method for dynamically encrypting and decrypting electronic documents using iris feature values. When the present invention supports encryption and decryption transfer of electronic documents based on local area network and wide area network, it can realize the uploading and distribution of electronic documents between departments in a safe and real-time manner, and meets the requirement of the security and confidentiality level of electronic documents. Background technique [0002] Electronic documents are the product of the development of terminal equipment and application systems such as computers, tablet computers, mobile phones...

Problems solved by technology

But the weak point that this method still exists is: first, the iris recognition that this method uses is just the first step as the encryption and decryption method, is used for verifying the identity of the person who encrypts and decrypts, and the iris device is actually used as the key The serial number of its own hardware means that the files encrypted on the same iris device all use the same key, which belongs to static encryption. Once the device is replaced, the key will be lost

However, this method still has the disadvantages that: the data security processing method is only aimed at the storage device described in this technology, encrypts the data flowing into the storage device, and decrypts the data flowing out of the storage device, and the encryption and decryption actions are performed by Completed by the same person, such an application is limited to personal use, and cannot be solved when uploading and distributing electronic documents

However, the shortcomings of this method are: this method is suitable for the client / server architecture based on the FTP protocol, it cannot realize point-to-point transmission between clients, and the timeliness cannot be guaranteed

However, the disadvantage of this method is that the file transfer in this system refers to the uploading and downloading between the client and the server, and it is necessary to install client management software on each network terminal, resulting in scattered waste of network terminal resources.
