Label Model Based Coverless Information Hiding Method

Abstract

Information hiding technology guarantees the security of information exchange in the internet. A highly secure information hiding method was presented recently -- Coverless information hiding and it attached many attention. But the low hiding capacity limits its application. A modified coverless information method called label model based coverless information hiding method was proposed in this paper. The new label model of the method use a tag to positioning the keywords as much as possible, and add a header file to hide the number of the keywords. The new method will hide more information compare with the coverless information hiding method before, because we usually hide fixed number of the information in the past. The experimental results show that the proposed method can improve the capacity of the method obviously.
