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, 2006Secret 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.

A hierarchical threshold secret image sharing
Pattern Recognition Letters, 2012In the traditional secret image sharing schemes, the shadow images are generated by embedding the secret data into the cover image such that a sufficient number of shadow images can cooperate to reconstruct the secret image. In the process of reconstruction, each shadow image plays an equivalent role. However, a general threshold access structure could

Secret image sharing with steganography and authentication
Journal of Systems and Software, 2004A 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.

Abstract In this paper, we propose a method such that a secret image is shared by n shadow images, and any r shadow images (r⩽n) of them can be used to restore the whole secret image. The size of each shadow image is smaller than the secret image in our method.

An Image Secret Sharing Method
2006 9th International Conference on Information Fusion, 2006This paper presents an image secret sharing method which essentially incorporates two k-out-of-n secret sharing schemes: i) Shamir's secret sharing scheme and ii) matrix projection secret sharing scheme. The technique allows a secret image to be divided as n image shares so that: i) any k image shares (k ? n) can be used to reconstruct the secret image

Progressive sharing for a secret image
Journal of Systems and Software, 2010Based on the wavelet transform, a new progressive sharing scheme is proposed to share a secret image into several shadow images using SPIHT encoding processes and Shamir's threshold scheme. Quality refinement of the recovered image is achieved by the data consumed from the threshold number (r) of shadow images and each single shadow image reveals no ...

An Image Secret Sharing Scheme with the Capability of Previvewing the Secret Image
Multimedia and Expo, 2007 IEEE International Conference on, 2007Some (k, n)-threshold image secret sharing schemes encrypt the secret image into n noise-like shadow images with size 1/k times that of the original secret image. The small size of shadow image makes this framework suitable for fast transmission in the distributed multimedia system where each shadow image is stored in the distributed storage node ...

Multiple secret images in multiple sharing images
SPIE Proceedings, 2012Internet based communications are evolving at a tremendous rate. Encryption of data has become an important way to protect data resources especially on the Internet, intranets and extranets. Steganography is a process of hiding data inside a sharing medium. A technique of hiding multiple images in multiple sharing images is proposed.
