With the rapid advancement and extensive application of artificial intelligence technology,
large language models (LLMs) are extensively used to enhance production, creativity …

In the past, video recording and video databases were relatively small. This makes the
manual keyword indexing and retrieval easy. However, in recent years, videos are now a …

In this paper, a multipurpose blind watermarking algorithm for color image based on discrete
wavelet transform (DWT) and discrete cosine transform (DCT) is proposed according to the …

In this paper a novel blind watermarking technique for color images using DCT has been
proposed. Inproposed technique cover image is decomposed into 3 planes, namely R, G, B …

A novel 3D watermarking algorithm by combining use of computational integral imaging (CII)
and cellular automata transform (CAT) is proposed in this paper. In this proposed scheme …

The area of optical color picture encryption has recently emerged as one of the most talked-
about subjects in the pitch of data security. Although it has been suggested that certain …

In today's hyper-connected globe, safe and secure interaction is becoming increasingly
essential, which has raised the need for trusted verification systems. The expanding …

A new scheme is proposed which uses the features of Discrete Cosine Transform (DCT) for
the embedding of the watermark coefficients and uses a pseudo-random sequence for …

In the past few years many new techniques and concepts based on data hiding have been
introduced for image authentication and copy right protection. With a lot of information …
