Strong threshold secret image sharing based on boolean operation

Secret image sharing is a method of dividing a secret image into number of shares according to valid participants. This paper discusses secure (n, n) strong threshold secret image sharing scheme, in which n number of encrypted (meaingless) shares are distributed to n number of participants and participants can reveal the lossless secret image when all n shares of secret image are available. With less than n shares participants are not able to generate the original secret image. In this Strong threshold scheme (n-1) or less than n shares should not reveal partial information about secret image.
