Abstract
The secret sharing is an important issue in confirming the security of confidential information. This paper proposes a generalized sharing and recovery scheme suitable for secret images. The scheme coalesces vector quantization (VQ) compression technique and conventional generalized secret sharing scheme to produce pseudo codebooks out of the secret codebook used for compressing the secret image. Every pseudo codebook is held by a participant of the generalized access structure for secret sharing. On the other hand, the secret image can be only recovered by all participants, who belong to the same qualified subgroup of the generalized access structure, to work together with their possessed pseudo codebooks
