Fixed Unmitigated Image Cryptography Schemes
V. Redya Jadav, Jonnalagadda Sravani · 2012
A image cryptography scheme (ICS) is a kind of secret sharing scheme which allows the encoding of a secret image into shares distributed to participants. The beauty of such a scheme is that a set of qualified participants is able to recover the secret image without any cryptographic knowledge and computation devices. An Extended Image Cryptography Scheme (EICS) is a kind of ICS which consists of meaningful shares (compared to the random shares of traditional ICS). In this paper, we propose a construction of EICS which is realized by embedding random shares into meaningful covering shares, and we call it the embedded EICS. Experimental results compare some of the well-known EICSs proposed in recent years systematically, and show that the proposed embedded EICS has competitive image quality compared with many of the well-known EICSs in the literature. In addition, it has many specific advantages against these well-known EICSs, respectively.
