    In this paper, the effects of steganography in different image formats (BMP, GIF, JPEG and DWT coded) are studied. With respect to these formats, we try to give an answer to the following questions. (1) How many bits of noise (i.e. the textual secret message) can be injected without perceptually deteriorating the quality of the image? (2) How and where should one inject these bits in order to achi... View full abstract»

    Certain deterministic nonlinear systems may show chaotic behaviour. Time series derived from such systems seem stochastic when analysed with linear techniques. However, uncovering the deterministic structure is important because it allows to construct more realistic and better models and thus improved predictive capabilities. The paper provides a new approach for features of chaotic systems defini... View full abstract»
