A Highly Adaptable Secret Image Sharing Method

Abstract

The invention discloses a highly adaptable secret image sharing method, which includes: receiving a secret image sent by a first terminal that needs to be encrypted, and using the pixel values ​​of the secret image to construct a binary symmetric matrix on a finite field GF; According to the identifiers of k trusted participants and the binary symmetric matrix, k coefficient matrices are obtained, and the k coefficient matrices are sequentially converted into k eight-bit binary data; n masking images are obtained, and utilized The n masking images process the k eight-bit binary data to obtain n shared images, and send them to n participants respectively, so as to realize the splitting of the secret image; when reconstructing the secret image , obtain the unprocessed k pixel values ​​in the known k shadow images, and use the k pixel values ​​to obtain the original coefficient matrix; use the original coefficient matrix and the identifier of the holder of the k shadow images , to recover the secret image.

Description

technical field [0001] The invention belongs to the technical field of computer software, in particular to a highly adaptable secret image sharing method. Background technique [0002] With the advent of the industry 4.0 and 5G era, the amount of image data has increased dramatically; and in real life, the economic losses caused by image data leakage and loss are also increasing. According to the latest update of the global data field by the International Data Corporation (IDC), more than 59ZB of data will be created, captured, copied and used globally this year, and this data will continue to grow. The compound annual growth rate (CAGR) for the next five years is expected to be about About 40.3%, of which image data accounted for more than about a quarter, and the economic losses caused by image data leakage and loss have reached as high as 1.2 trillion US dollars. Therefore, in the security, personalization, efficiency and personal Finding the right balance between privac...

Problems solved by technology

[0005] The technical problem solved by the solution provided according to the embodiment of the present invention is that in the current image secret sharing technology, equating all participants cannot be well adapted to real life, and at the same time, some participants have unequal amounts of information, and This not only increases the transmission burden, but also is extremely vulnerable to attacks, and the security is not high
