In this article are discussed techniques of hiding information messages in cover image using
direct spectrum spreading technology. This technology is based on the use of poorly …

Direct spread spectrum technology is traditionally used in radio communication systems with
multiple access, for example, in CDMA standards, in global satellite navigation systems, in …

This paper presents a method of embedding information in digital images and video, which
helps to trace illegal copies. This method of watermarking uses the principle of direct …

Cryptography and Steganography are the two popular methods for secure data hiding and
transmission available broadly. The techniques used information in order to cipher or cover …

We describe a reliable and accurate method for detecting least significant bit (LSB)
nonsequential embedding in digital images. The secret message length is derived by …

We present a method of embedding information within digital images, called spread
spectrum image steganography (SSIS) along with its payload capacity. Steganography is …

In this paper, we apply the theory of hypothesis testing to the steganalysis, or detection of
hidden data, in the least significant bit (LSB) of a host image. The hiding rate (if data is …

An overview of current steganographic methods for secret message hiding and digital
watermarking is presented. A general theory of message hiding is used to put various …

We present a new method of embedding information within digital images, called spread
spectrum image steganography (SSIS). Steganography, which means" covered writing" in …

This article reports on a lossless data hiding scheme for digital images where the data
hiding capacity is either determined by minimum acceptable subjective quality or by the …
