Fan Yu · Communications technology · 2009
By making use of the characteristics for shorter key and higher security of elliptic curve cryptosystem and improved LSB, a solution for combing the elliptic curve cryptosystem and information hiding is presented. This paper describes a secret information hiding scheme based on elliptic curve cryptosystem and improved LSB. And the processes of embedding and extracting secret information in the scheme are discussed in detail. The detection on whether there exists secret information embedding could be implemented according to the characteristics of BMP images. And the results of information hiding achieved by this scheme are also given.
