Design and Implementation Criteria for a Secure Steganography System from the Passive Defense Perspectives

The parameters of being secret and remaining secret contribute to the mitigation of vulnerability and enhancement of resistance and facilitation of security management against enemy's military threats and actions. Apparent normalization of communications is one of the most significant and obvious issues of steganography. Therefore; steganography is inclusive of the principles and laws of passive defense in countering software and electronic threats and enemy's other new threats in order to maintain and safeguard information, communications and computer systems. An unsafe communication channel by which the transmission of sound-digital, image and video medias is possible and access to the communication of the other side(the same relevant receiver) is made possible, as well, steganography can also be practically implemented on such a domain which safeguards the relevant information considering the special conditions and criteria, regardless of the origin of threat.This article is intended to review the special conditions and criteria which have to be observed before designing the steganography product(design limitations) accompanied by a case study.
