A Survey on Data Hiding and Compression Schemes
Data hiding has a vital role to play in information security. Using a data hiding technique, secret information is hidden into cover digital content. Compression techniques and data hiding techniques received much less attention from the research community and from industry than cryptography. In past research many data hiding and image compression techniques has been developed, it works indepen...
متن کاملA survey on digital data hiding schemes: principals, algorithms, and applications
This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...
متن کاملSemantic image compression based on data hiding
This study proposes a novel scheme of semantic image compression. A compressor firstly creates a compact image by gathering a part of pixels in an original image, and calculates estimation errors of the rest pixels. Then, a compressed image is produced by embedding the estimation errors into the compact image using data hiding techniques. This way, the compressed image are made up of a small nu...
متن کاملSurvey of SIFT Compression Schemes
Transmission and storage of local feature descriptors are of critical importance for mobile visual search applications. We perform a comprehensive survey of Scale Invariant Feature Transform (SIFT) compression schemes proposed in the literature and evaluate them in a common framework. Further, we compare the different schemes to the recently proposed low bit-rate Compressed Histogram of Gradien...
متن کاملSecured Data Hiding based on Compression Function and Quantization
Data hiding is the process of secretly embedding information inside a data source without changing its perceptual quality. In this paper, Quantization Index Modulation and the compression function of μ-Law standards for quantization are used. The proposed method transforms the host signal into the logarithmic domain using the μ-Law compression function. Then, the transformed data is quantized u...
