Watermarking and Information-Hiding
نویسنده
چکیده
Watermarking is the process of embedding a watermark into host signal that can be in the form of Audio, Video, and Image .The watermark can be embedded as Logo, Text, and String. The main objective of embedding watermark is to protect the data from unethical hackers over Internet. This watermarking scheme can be embedded in different domains which can be referred as Spatial and Transform domain. Further Transform domain is divided into different types which are DCT, DWT, DFT. Watermarking can also be said as Information-Hiding, because the main factor is to hide the original details from the people who are sitting on internet. KeywordsWatermarking, Audio, Image, SpatialDomain, Transform-Domain

A 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 کاملHigh capacity steganography tool for Arabic text using 'Kashida'
Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...
متن کاملInformation Hiding: User Point of View
Information hiding techniques have recently become important in a number of application areas. The information hiding scheme can be classified into two main application fields: steganography and watermarking. There is a considerable amount of published work in this field. However, little work addresses information hiding from the user's point of view. Potential problems, user requirements, eval...
متن کاملApplications of Information Hiding and Digital Watermarking
Digital watermarking denotes the hiding of information in general documents, where the embedded information can be exploited to combat copyright infringements or to verify the integrity of a document. We emphasize that blind watermarking, where the original document is not known to the watermark receiver, can be interpreted as communication with side information at the encoder. Significant impr...
متن کاملInformation Hiding and Its Criteria for Evaluation
Within information hiding technology, digital watermarking is one of the most important technologies for copyright protection of digital content. Many digital watermarking schemes have been proposed in academia. However, these schemes are not used, because they are not practical; one reason for this is that the evaluation criteria are loosely defined. To make the evaluation more concrete and im...
متن کاملPower: A Metric for Evaluating Watermarking Algorithms
An important parameter in evaluating data hiding methods is hiding capacity [3] [11] [12], [16] i.e. the amount of data that a certain algorithm can “hide” until reaching allowable distortion limits. One fundamental difference between watermarking [4] [5] [7] [8] [9] [13] [14] [17] [18] [19] [20] [21] [22] [23] and generic data hiding resides exactly in the main applicability and descriptions o...
