The Study Of Sonar Image Information Hiding Algorithms Communication And Information System

For the development of folk and ocean Marine development all over the world, theapplication of Marine underwater communication becomes more and more widely. Themilitary communication security in the unsafe environment has been being very important asbefore. On one hand, the communication with froglocks who are working close to the enemy.On the other hand, with the ocean development, all kinds of civil underwater communicationnetwork will form in the future. It requires secrets safe in the communication underwater, thatcompetition between Countries and companies having different interests and protection theirown rights and interests. So it is very necessary achieving underwater stealth communicationusing the sonar image information hiding technique.This paper mainly researches several sonar image information hiding algorithm in theunderwater stealth communication aiming at the three key index: hiding capacity,concealment and robustness. And the characteristics of each algorithm are given throughsimulation analysis. Aiming hiding capacity it is researched that basing on the chaos mappinglesion thought scrambling Tabu optimization k-LSBs algorithm. Watson visual model is usedin order to improve the concealment of information hiding based on energy modulationalgorithm. Finally the research of spread spectrum sonar image information hiding project,greatly improves the underwater stealth communication robustness. Each algorithmmentioned is simulated in this paper through computer to simulate the real communication ofthe situation.It is should be noted that, any kind of information hiding algorithm can only be a balancein each performance index instead of getting best in all aspects. Therefore, in the practicalapplication the algorithm should be select appropriately according to the actual channel andthe main goal to realize, so as to obtain the best performance advantage.
