A high-capacity watermarking technique for audio signals based on MDCT-domain quantization
Watermarking is a technique that consists in hiding/embedding binary information within a signal in an imperceptibly way, meaning in the present context of audio signals that the mark is inaudible. Watermarking was first used for the protection of digital contents as part of the DRM (Digital Rights Management). In this context of secured applications, important efforts were devoted to ensure ro...
متن کاملA Novel Technique for Steganography Method Based on Improved Genetic Algorithm Optimization in Spatial Domain
This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...
متن کاملA Spatial Domain Reversible Visible Watermarking Technique for Textured Images
Digital watermarking is widely used as one of the techniques to identify ownership and protect copyrights of digital images. The watermark inserted may be visible or invisible. A Visible watermark, which is nothing but a digital pattern logo or trademark, directly convey ownership information on the media, while invisible watermarks do it indirectly after being extracted with the help of extrac...
