Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At present, with the fast development of information technology more data and images are available on the internet. So there is a need to provide some kind of authentication to such significant data. When the sender transmits the image/data to the receiver, there may be intruders present in between who may capture the image/data. The usage of digital data in modern communication has been rapidly growing. In order to provide security for digital data the steganography is used. Steganography is popularly used for data hiding. The process of embedding data in to the cover medium is known as steganography. The key parameters namely imperceptibility, capacity, and security are used for data hiding. Imperceptibility is measured by using PSNR, capacity can be determined by using embedding rate and security is addressed by means of encryption. In this work the following methods have been implemented. (i) Threshold based Reversible Data Hiding (TBRDH) Method (ii) Distortionless data hiding using DCT (DDHDCT) Method (iii) Lifting Scheme Wavelet Transform for RDH (LSWT-RDH) (iv) Secure Force Algorithm for Data Hiding (SFADH) Method 116 pp. Englisch.
