摘要：
In this paper, a new secret sharing scheme based on the discrete fractional random transform (DFRNT) is proposed. In order to guarantee security, secret image first is permuted by means of discrete fractional random transform and then the algorithm transform the permuted secret pixels using module mechanism, after the scheme apply (t, n)-threshold secret image sharing model. In the decoder, the cover and secret images can be perfectly recovered. Experimental results demonstrate the effectiveness of our scheme.
