Design And Implementation Of Algorithm To Generate Electronic Documents’ Security Label Based On Information Hiding Technology

At present, the national security work gets more and more attention, some assessment guide involving state secrets points out the importance of security classification marked and Measurements rules that security classification marked is a necessary item. So the research of security classification marked is very important, but the algorithm to generate security classification marked in the electricity document is in the study phase and has no standards. This paper proposes an algorithm to generate security classification marked in the Word document based on information hiding technology. The algorithm proposes the concept of safety credible Base seed set. The Base seed can generate Work seed and it can make sure the algorithm is secure. In the algorithm, the security classification marked is to be hidden information, the Word document is information carrier. The algorithm hides the security classification marked securely and effectively, and keeps the security classification marked and information carrier entirety.This paper’s fourth part introduces the security system based on the algorithm and describes the design and implementation of security system. The fifth part introduces the test on the security system and proved the correctness of the security system and feasibility of the algorithm. The last part is summarizes and look into the distance of the author.
