Image multi-secret transmission method, device and system based on bidirectional authentication

Abstract

The invention relates to the technical field of image secret transmission and discloses a multi-secret transmission method, device and system based on a bidirectional authentication image. The methodcomprises the following steps of: establishing an encrypted carrier image database, encrypting an image, establishing transmission channel authentication, performing encrypted transmission, decryptingdata and recovering an image. The device comprises a voice receiving terminal, a client, a server and a background database, the system comprises one or more processors, a storage device and a multi-secret transmission device based on bidirectional authentication images. The image is split and rearranged, so that the image transmission security and privacy protection capability can be improved, the image data is prevented from being maliciously eavesdropped or counterfeited, meanwhile, a relatively good maintaining effect of the image is ensured, distortion is avoided, and the method has a relatively good practical value.

Description

technical field [0001] The invention relates to the technical field of secure image transmission, in particular to a method, device and system for multiple secure transmission of images based on two-way authentication. Background technique [0002] With the rapid development of science and technology, the Internet industry has risen, and data transmission has become an indispensable communication method in people's daily life. In order to ensure the safety of the communication process, data is transmitted between the sender and the receiver. Whenever, the transmitted data needs to be encrypted. [0003] In some occasions with high security requirements, how to achieve unity from mutual authentication of data transmission to confidential transmission of data, while not only ensuring general security, but also overcoming various malicious active attacks and Data theft is also a key issue to be solved; [0004] At present, the digital images obtained by people have reached te...

Problems solved by technology

[0004] At present, the digital images obtained by people have reached tens of billions, which play an important role in the national economy and daily life. The transmission of images on the network is becoming more and more frequent, and the confidentiality and privacy of images are becoming more and more popular among users. At present, the information encryption method commonly used in image transmission and storage makes it impossible for others to know the content of the image itself, but after seeing the encrypted image, others think it is important and will decipher it. If it cannot be deciphered, it will be destroyed, which is not conducive to the protection of the image. Safety
