A technique for information security has been proposed in this paper.
Steganography is a technique which hides data in digital mediaso as not to
stimulate an eavesdropper doubt. Digital media includes image, audio, video
etc. An important thing to notice about this technique is that, it does not let
any third party to know that any data is hidden. Only the sender and intended
recipient could view the information. In this paper, Bit Insertion Technique is
used to hide data that is to be sent. Data is being hidden in high frequency
areas as well as in non-edge areas. Reason of hiding data in edges is that any
alterations made in edge areas of an image are invisible to naked human eye.
Presented algorithm preserves the quality of image after hiding data in terms
of PSNR. Experimental results show that proposed methodcaters both high
embedding capacity and preserves the visual quality of the stego image.
