Abstract (in Japanese) (See Japanese page) 
(in English) Due to the development of information technology, many types of data including documents, image and audio, etc. is digitized easily and stored on computes. It is worth to consider the content security of digitized media because important media data is also digitized. Information security is one of important technical issues under such environment. Secret sharing is one of the information security techniques to protect content security. Shamir’s (k,n) threshold secret sharing is typical one. Original information is divided into some piece called a share. The original information can be reconstructed by collecting k shares completely, and can’t be reconstructed when the number of shares is less than k at all. Data size in each share is equal to the original size. This means that the total size of all shares equals the size of original times n. In this paper, we study to reduce the size of share for image data secret sharing, and report the experimental results for the secret shareing (k,L,n) threshold secret sharing based on (k,n) secret sharing and image representation using compressed sensing.
