As far as security of data in text form is concerned it becomes necessarily important to use appropriate technique so that aim of security can be achieved. „Steganography‟ has proved itself to a greater extent that it can perform such a task successfully. Steganography deals with enclosing the message in an image privately. In this paper, a brief way of placing message bits in the image by replacing the pixel of image has been proposed with the help of Matlab. The information is unexpected to a third party rather than the sender and receiver which are hidden in the image using this technique.Keywords

In this paper, the various technical aspects (such as image acquisition, imaging used, iris localization and pattern matching)used in Iris recognition technology have been discussed and elaborated. The three cameras can be used to capture the picture of the entire torso of a person in which one of the three cameras will capture the image of eye only including upper and lower eyelids. Then two techniques Near Infra Red (NIR) and Visual Wavelength (VW) can be used for imaging purpose. NIR is widely used as most of the people of world have black eyes, whereas VW is used for colored eyes. After imaging, iris’s picture is localized and ultimately the pattern of iris is encoded to generate 512 byte human bar code.
