“…Various DWT based watermarking techniques have been proposed which provide greater robustness [6,7,10,12,13,14]. Hsieh [6] proposed an approach by using the concept of Zerotree from Embedded Zerotree Wavelet (EZW) coding introduced by Shapiro [3].…”

In recent times, digital watermarking has become one of the advanced technologies to protect images from illicit manipulations. A non-blind robust Discrete Wavelet Transform domain watermarking approach for images is introduced in this paper. Based on the parent-child relationship between wavelet coefficients, the Set Partitioning in Hierarchical Trees (SPIHT) algorithm is applied on the transformed host image to find out the significant coefficients for embedding binary patterned watermark image. Higher level of security is achieved by scrambling the watermark using Arnold transform. The selected significant wavelet coefficients are adapted using Noise Visibility Function (NVF) to achieve enhanced imperceptibility. The scheme is tested against various image processing operations including JPEG compression, noise addition, filtering, cropping, histogram equalization and contrast adjustment. The experimental results showed that the proposed algorithm is highly robust. Keywords-Arnold transform, digital image watermarking, discrete wavelet transform (DWT), noise visibility function (NVF), set partitioning in hierarchical trees (SPIRT).

“…Now all of them are key based whose strength depends on the key size and also the executions of such techniques are computationally intensive. Moreover they convert plaintext to cipher text, thus attracting the attention of attackers with more seriousness [6,7]. The conventional encryption techniques require message block sizes of 64 bits or higher and requires intensive mathematical operations which make it less vulnerable to crypto analysis.…”

Abstr act. Effective and light weight, in terms of computational requirements robust encryption algorithms are preferable for data hiding and data security applications. Steganography data hiding, watermarking for copy right protection, secure transmission of biometric data to local or remote sites for validation and recognition, and secure data storage in a digital system are such few applications. We report in this paper an encryption algorithm which is simple and light weight in implementation but robust in its capability to hide or secure the message data. The algorithm requires small block and code based substitution of binary message data before embedding, storage or transmission. We report our work on steganography and watermarking using our proposed encryption algorithm and then simple LSB encoding, and data storage and data transmission applications with our encryption algorithm on the data. We observe higher performance compared to almost all LSB encoding techniques. The encryption algorithm thus provides both data security and data hiding capability and may be applied on all types of binary data processing as an optional and additional step.Keywor ds: LSB encoding, watermarking, Biometrics, Security Almost every information today, be it text, audio, music, image, video or multimedia are dealt with digital techniques for storage, transmission, or protection. Modern communication systems or storage systems are heavily dependent on computer systems and internet and hence are prone to attack. Also as most of the user information is in digital domain, digital signal processing for storage, compression, hiding and security are most prevalent now a day. The message information often needs encryption like processing techniques before they are put to sto-1 MD. A. Hussain ()
