The Research of Secret Image Sharing Based on RS Erasure Code

Secret image sharing is an attractive research problem in information security filed. After more than ten years of development, secret image sharing has become a relatively independent area. Most current secret image sharing scheme used Lagrange interpolation of Shamir scheme as the core idea, but which way will greatly reduce the computational efficiency and system availability without a doubt because of a huge amount of data in images. According to the internal relationship between coding theory and secret sharing technology, the paper proposed a secret image scheme based on coding theory. In addition to have advantages which most secret image sharing schemes based on Lagrange interpolation own, the new method which has a more simple idea reduced computational complexity and easy to extend the field of video and audio, so has a more obvious practical value; The design and realization of the new secret image sharing scheme has indirectly proved the internal relationship between coding and secret sharing scheme.
