Protecting seaport communication system by steganography based procedures

Research output: Contribution to journalArticlepeer-review


Rival companies compete against each other in business and therefore they try to obtain data that is usually held in the hands of seaports. If a company succeeds to damage one of its rival companies, the company will increase in value. Therefore there is risk for any data in the hands of a port; in spite of this, there is no cybersecurity standard for the maritime industry or for enforcement agencies; despite the fact that the need of secure communication is indispensable. Still, using encrypted messages have a noteworthy disadvantage. Each person who sees the message recognizes that there is a cryptic message. This paper introduces a technique of Steganography, that is to say - transmitting encrypted messages in images compressed by the well known JPEG format. In point of fact, the system modifies the pictures a bit, but this modification is totally unnoticeable. The image seems to be an immaculate picture, while truly the picture does include some extra information.
