Yair Wiseman · International Journal of Security and Its Applications · 2014
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.
