Color visual multi-secret sharing scheme with dynamic and verifiable threshold
Zhuojun Liu · Journal of Computer Applications · 2007
A dynamic and verifiable threshold color visual multi-secret sharing scheme was proposed.The scheme shared many secret images so that any t or more sub-secrets could recover the secret image,but any t-1 or fewer of them gained no information about the original secret image.In the scheme,multiple secrets can be shared in one sharing session.The sub-secret of each participant can be used by many times,and the secrets can be renewed without renewing the sub-secrets of the participants.What is more,a participant can be flexibly accepted or fired.
