Improved File Security System Using Multiple Image Steganography

Abstract

Steganography is the process of hiding a secret
message within an ordinary message & extracting it
at its destination. Image steganography is one of
the most common and secure forms of
steganography available today. Traditional
steganography techniques use a single cover image
to embed the secret data which has few security
shortcomings. Therefore, batch steganography has
been adopted which stores data on multiple images.
In this paper, a novel approach is proposed for
slicing the secret data and storing it on multiple
cover images. In addition, retrieval of this secret
data from the cover images on the destination side
has also been discussed. The data slicing ensures
secure transmission of the vital data making it
merely impossible for the intruder to decrypt the
data without the encrypting details.
