[en] Many information hiding techniques have recently been analyzed
as they could help manage part of the digital rights.
Among the general framework of information hiding, the
focus has been put on steganography and on watermarking
techniques.
This paper proposes an entropy based technique for data
embedding in images with a specific target, sometimes referred
to as feature location: inclusion of a maximum amount
of information instead of robustness against attacks.
After an introduction, we analyze the error that results from
a modification of the least significant bits. Then we describe
our embedding technique. Finally we examine the upper
bound of information that can be embedded in the least significant
bits by means of our technique and we conclude.
