RESEARCH ON SECRET SHARING OF IMAGE BASED ON CODING THEORY
摘要
Abstract
Secret sharing of image is a research subject with unique attraction in information security technology filed .After developing almost 20 years, secret sharing of image has become a relatively independent technical domain , but far from perfect level .Most of the current secret sharing scheme for image uses Lagrange interpolation of Shamir ’ s scheme as their core idea; however for images with huge amount of data, this will greatly reduce the computational efficiency and system availability .According to internal relationship between the coding theory and the secret sharing technology , in the paper we propose a coding theory-based secret scheme of image .In addition to having the advantages which most secret sharing schemes for image based on Lagrange interpolation have , the new method reduces the computational complexity remarkably and has the features such as simple idea , easy to implement , convenient in extending to the field of video and audio , etc., therefore has more apparent practical value .Besides, the realisation of the coding-based secret sharing system for image indirectly proves the internal relationship between coding and secret sharing .关键词
