  A new technique for data hiding in digital image is proposed in this paper.
Steganography is a well known technique for hiding data in an image, but
generally the format of image plays a pivotal role in it, and the scheme is
format dependent. In this paper we will discuss a new technique where
irrespective of the format of image, we can easily hide a large amount of data
without deteriorating the quality of the image. The data to be hidden is
enciphered with the help of a secret key. This enciphered data is then embedded
at the end of the image. The enciphered data bits are extracted and then
deciphered with the help of same key used for encryption. Simulation results
show that Image Quality Measures of this proposed scheme are better than the
conventional LSB replacing technique. The proposed method is simple and is easy
to implement.
