Watermarking is an important technique for protecting sensitive e-multimedia data and
intellectual property. Watermarking techniques are used for many applications such as …

In this paper, a novel robust color image watermarking method based on Discrete Cosine
Transform (DCT) and Discrete Wavelet Transform (DWT) is proposed. In this method, RGB …

Sending image in a plain form has a high risk for the data being vulnerable to steal. Thus,
due to reducing the risk, data security techniques should be implemented. Data security …

This research proposes a method to enhance the payload message by embedding
messages on the dilated edge areas by the Least Significant Bit (LSB) method. To add …

The security aspect is very important in data transmission. One way to secure data is with
steganography and cryptography. Surely research on this should continue to be developed …

Many people have used the internet in daily communication. The rise of internet data theft
makes the security of data transmission becomes very important. Cryptography and …

Imperceptibility and security are the two most important things in StegoCrypt techniques. In
this paper, we have proposed the technique of inserting messages to the edge of the image …

Public networks such as the Internet are becoming more sophisticated, faster, and cheaper,
so that more and more used for information exchange. This may increase the likelihood of …

This study proposed concealment of information through watermarking techniques using a
combination of Haar Wavelet Transform (HWT) and Chinese Remainder Theorem (CRT) …

In order to solve the contradiction between watermark transparency and robustness, this
paper combines Non‐subsampled Contourlet Transformation (NSCT), Discrete Wavelet …
