Abstract

With the proliferation of digitized media, the need of digital watermarks as a copyright protection, ownership identification and a secure way of embedding information has become important. A useful watermark technique should be robust against malicious attacks or tampering to remove the watermark and should not greatly affect the quality of the original file. In conventional cryptographic systems, once the information is decrypted, the recipent can misuse it. The reproduction and retransmission cannot be tracked easily. In these project, LSB watermarking technique for digital image is investigated. A software system, consisting of watermark embedding and recovery is implemented with single or multiple watermarks embedding. The robustness and effectiveness of this watermarking technique is tested using the GIF and JPEG file compression format. A comparator is designed and implemented to further enhanced the robustness when subjected to compression. All the results of the LSB watermarking techniques are tabulated.
