Embedding Algorithm using multiple pseudo random number generators with LSB technique

Digital Watermarking is a technique for embedding personal or confidential information within an image; video or text .The paper proposes an embedding method that implements multiple pseudo random number generators the cover image file will be segmented into number of block each contains a specific pixels length. The first PRNG is used to generate secret key by chaotic map for encrypting the logo image before the embedding process, the second PRNG generates random number that to be used for randomly selecting the pixels from each block to be modified with watermark bits by LSB method. The randomness of the keys has a strong impact on the system’s security strength for being difficult to be predicted, guessed, reproduced, or discovered by a cryptanalyst. Obtained results were satisfactory and suggest that, this technique would be suitable for applications involve cryptography, steganography, and copyright protection.
