Scalable secret image sharing

Signal Processing: Image Communication, 2007
In this paper, we propose an innovative scheme, namely the scalable secret image sharing scheme, for sharing an image O among n participants such that the clarity of the reconstructed image (i.e., the amount of information therein) scales with proportion with the number of the participants.

Secret image sharing with smaller shadow images

Pattern Recognition Letters, 2006
Secret image sharing is a technique for protecting images that involves the dispersion of the secret image into many shadow images. This endows the method with a higher tolerance against data corruption or loss than other image-protection mechanisms, such as encryption or steganography.

Secret image sharing with steganography and authentication

Journal of Systems and Software, 2004
A novel approach to secret image sharing based on a (k, n)-threshold scheme with the additional capabilities of steganography and authentication is proposed. A secret image is first processed into n shares which are then hidden in n user-selected camouflage images.
