الملخص الإنجليزي

Digital Watermarking is a technique for embedding personal or confidential information within an image, video or text.

This paper proposes an embedding method that implements multiple pseudo random number generators (PRNGs).The cover image file will be segmented into number of blocks, each contains a specific pixel 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 be used for randomly selecting the pixels from each block to be modified with watermark bits by LSB embedding method.

Two seed keys were implemented, one for each PRNG, and they will represent the personal or the private keys for the watermarking process.

The randomness of these keys has a strong impact on the system’s security strength for being difficult to be predicted, guessed, reproduced, or discovered by a cryptanalyst.

Experimental results of applying the proposed technique on embedding and extraction of logos of various types and sizes into vast number of images were satisfactory, as they resulted into fairly acceptable level of peak signal to noise ratio and low error values.

Hence, this technique would be suitable for applications that involve cryptography, steganography, and copyright protection.
