Abstract:
The demand of security is getting higher in these days due to easy reproduction of digitally created data. Digitally hide the secret information in some media content like digitized identification card, student’s registration card, e-passport, etc is the emerging technique for security protection of these media. Information hiding techniques have recently become important in a number of application areas. Digital audio, video, and pictures are increasingly furnished with distinguishing but imperceptible marks, which may contain a hidden copyright notice or serial number or even help to prevent unauthorized copying directly. Military communications systems make increasing use of trace security techniques which, rather than merely concealing the content of a message using encryption, seek to conceal its sender, its receiver or its very existence. Similar techniques are used in some mobile phone systems and schemes proposed for digital elections. Criminals try to use whatever trace security properties are provided intentionally or otherwise in the available communications systems, and police forces try to restrict their use. In this system, a GA (Genetic Algorithm) based secret information hiding technique is presented for checking the security of student’s registration cards. This can check that the card is real or not for security assessment of examination. The secret code like (001, 002,) or secret image is hide into the contents (images’ pixels) of digitized student’s registration card and we employed GA to choose the best positions for hiding process.
