Abstract
This 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 (klesn) can be used to reconstruct the secret image in lossless manner and ii) any (k-1) or fewer image shares cannot get sufficient information to reveal the secret image. It is an effective, reliable and secure method to prevent the secret image from being lost, stolen or corrupted. In comparison with other image secret sharing methods, this approach's advantages are its large compression rate on the size of the image shares, its strong protection of the secret image and its ability for realtime processing
