Yong Fang · Journal of Beijing Electronic Science and Technology Institute · 2011
Adding and management of secret level identification are the basis for multi-level security.Multi-level security system requires that secret level identification should be non-tampering or non-stripping.This paper presents a secret level identification adding method for binary document based on digital watermarking as the following steps:generating multi-identification based on the Chinese Remainder Theorem;realized the identification of non-tampering or non-stripping with binary document and corresponding to User rights by adopting the binary digital watermarking and encryption technology;and finally,the paper gives the security analysis of this method.
