“…The vector quantization scheme was employed to encode the secret images (Hu, 2003). Wu and Tsai (2000) proposed a method to embed a secret image into a cover image. This method was based on the similarity among grey values of consecutive image pixels, as well as the variation of human visual insensitivity from smooth to contrastive.…”

“…Experiments found that the peak values of signalto-noise ratios of the method were high and the resulting stego-images were imperceptible (Wu and Tsai, 2000). Haiping et al (2013) proposed a novel method of a blind, colour image information-hiding algorithm based on grey prediction to hide the image.…”

The main aim of this technique is to prevent the capture of secret data during the exchange/transfer between the source and destination, without the knowledge of intruder. A secret message is represented as an image, and the same image is encrypted by the Triple Encryption (TE) technique. This can be divided into three types of processes. These processes are Reverse Matrix (RM) encode, Alpha-Encryption (AE) and Hill Cipher (HC) encryption. In the RM process, the original secret image is hidden within a cover image. The encoded cover image pixels are converted as characters using a lookup table in the AE process. The encrypted cipher characters are once again encrypted in the HC encryption process. The main advantage of this proposed technique is that, to strengthen the proposed technique the pixels positions are interchanged in every stage. After the encryption, the cipher's data are sent to the destination for the reconstruction process. The Triple Decryption (TD) technique is divided into three processes of: Inverse Matrix (IM) decode, Alpha-Decryption (AD) and HC decryption. The received cipher data are decrypted by the HC decryption and AD processes. Finally, the decrypted data is decoded by the IM decode process. In this process, the original secret and cover images are obtained. In addition, to measure the performance of the proposed algorithm, the standard parameters are considered. The results show that the proposed algorithm provided a high Peak Signal to Noise Ratio (PSNR), good Correlation Coefficient (CC), minimum execution time and high CIA (Confidentiality, Integrity and Authentication) compared to existing encryption methods. Therefore, using this proposed method, we can obtain 100% of the original image and the secret data can be prevented from interception by intruders/third parties.

“…Digital watermarking technique is the process of embedding information into digital signals. In generally, digital watermarking technique can be classified into spatial-domain technique [4][5][6] and frequency-domain [7] technique. Spatial-domain technique embeds some information in pixels of an image.…”

“…VC technique is a special encryption technique to hide information in images in such a way that it can be decrypted by human vision, if a correct key image is used. However, Chen et al [4] pointed out the following two security problems. (1) When analyzing the value of low sub-band and high/middle sub-band while using DWT, an adversary can easily find out that the former is always equal or greater than the latter.…”

This paper proposes a new efficient and secure copyright protection scheme for digital watermarking by using visual cryptography technique. The proposed scheme has the following merits compare with previous related schemes: (1) The proposed scheme uses simple codebook to generate a watermarked image. (2) The proposed scheme does not need to expand the watermark image. (3) The proposed scheme eliminates two security problems on the previous Lou et al.'s scheme which that the problem of stability of relationship between discrete wavelet transform (DWT) coefficients and the problem of ambiguity of watermark verification. As a result, the proposed scheme is more efficient and secure compare with previous related schemes.
