Digital image watermarking is the process of embedding an identifying piece of data in a digital image. In this study, a secure watermarking scheme for images with confident capacity is explored, based on fractal image coding and a chaotic function. In this paper an image encryption scheme is presented, in which shuffling the position of image pixels is performed using the Arnold's Cat Map to ensure...
Integrity measurement is an important attribute in trusted computing. An integrity measurement model for computing platform is proposed, which aims at providing effective measurement and security protection for the booting of the platform, the loading of the process and the running of the procedure. The trusted platform which is based on embedded system and virtual machine can tolerate untrusted components...
Most steganographic techniques use either LSB or DCT coefficients to secretly embed data inside images. The first technique, has the drawback of being able to encrypt only one bit per color pixel. Recently, two new techniques for hiding data using Fibonacci decomposition has been developed, which enable a more sophisticated approach. In this work, we present a new embedding method, which generalizes...
