In order to solve the problem of non-restoration of PVSS, in this paper, we propose a method to recover the secret image without using the Boolean operation of the matrix matrix. In the lossless recovery process, each column base matrix will be "and" and "exclusive or" operation to get the original image anti-color image, and then the image can be obtained by the lossless secret image, this method can be applied to the general ( k, n ) threshold lossless recovery. In the absence of a computing device, it can be decrypted by superimposing, in the XOR computing device, it can realize lossless recovery. Experimental results show that the proposed algorithm can guarantee the gradual visual secret sharing, complete the restoration of the secret image, the operation is simple and efficient, and has a strong practicability.
