Steganography is the art of secret communication between two
parties that not only conceals the contents of a message, but also
its existence. Steganography has advantages over cryptography since
message can be communicated to the desired recipient without
raising any suspicion. Steganalysis attempts to detect the
existence of embedded data in a steganographically altered cover
file. This book describes three JPEG steganography algorithms and
one steganalysis algorithm. The steganography algorithms are
primarily based on restoring the statistics of a JPEG image after
embedding data in them which results in low detection rate as
compared to other existing algorithms. The steganalysis algorithm
uses second order statistical features along with machine learning
to train and predict if an image contains embedded message.
Steganography can be used in many applications. In commercial
sector, data hiding techniques can be used to enforce copyright on
a digital medium. The access control information can be embedded
inside the digital medium which can eventually be verified by the
media player before playing the file.
