Digital Watermarking: Applications, Techniques and Attacks

International Journal of Computer Applications, 2012

As information transmission technology progresses, the technology to protect data from unauthorized users also needs to be enhanced. Data can be plagiarized, modified, deleted etc without proper authentication and authorization. Various security mechanisms have evolved that enhances the security of digital media. Each technology to be applied successfully should ensure a balance between the three pillars of security; confidentiality, integrity and availability. Digital watermarking is one such technique. It is a mechanism to monitor the digital media with the help of information residing within the content itself. To put it simply, digital watermarking is embedding of information into source content that can be detected and extracted. Digital watermarking can be applied to media like text, audio, image, video etc. This paper provides a comprehensive idea behind this technology and its usage.

IJERT-Review Paper on Security Measures in Digital Watermarking

International Journal of Engineering Research and Technology (IJERT), 2020

https://www.ijert.org/review-paper-on-security-measures-in-digital-watermarking https://www.ijert.org/research/review-paper-on-security-measures-in-digital-watermarking-IJERTCONV8IS10021.pdf Watermarking is the technique in which digital data is hidden in carrier signal. Steganography is the process in which digital data (file, message, video etc.) is embedded within another file, message and video. Steganography secures the information from intruders whereas watermarking algorithms are used for keeping the watermark robust to attack. When the intruder wants to penetrate the signal and tries to remove the watermark then quality of the signal is degraded and it becomes useless. There are many area in which information hiding is required. Two type of attacks are there. First one is active attack in which the attacker changes the whole content. Second one is passive attack in which the attacker tries to guess the secured information by eavesdropping. This paper presents different image data hiding attacks.

A Survey on Digital Watermarking Techniques

2013

A digital watermark is a kind of marker covertly embedded in a noise tolerant signal such as audio or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal. Embedding a digital signal (audio, video or image) with information which cannot be removed easily is called digital watermarking. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. In this paper, we present a comprehensive survey on various digital watermarking techniques such as robust, fragile and semi fragile watermarking techniques. This paper provides evidence that digital watermarking techniques are of increasing interest and are of gaining popularity. Keywords— Digital Watermarking, Robust, Fragile, Semifragile Watermarking

Watermarking presents the basic model for embedding and extraction of watermark. It is basically required to protect the information from the unauthorized access. The copyright protection, capacity, security, robustness etc are some of the important factors that are taken in account while the watermarking system is designed. This paper presents study of the digital watermarking process, concept, applications and its contributions in various other fields.

An Overview on Digital Image Watermarking and Its Techniques

The Digital image watermarking technology is being improved day by day, there are a lot of possibilities of reproduction and manipulation of digital multimedia such as digital image, digital audio and digital video. Hence the digital image watermarking methods have been designed and implemented for the purpose of protection. In this paper, we present an overview on Image Watermarking techniques. In digital watermarking techniques, we discuss the various factors used in watermarking, properties and application area where watermarking technique required to be used. The digital watermarking is a passive protection tool that used to secure the data of researchers and the information is hidden inside a signal which cannot be easily detected by unauthorized users. The digital watermarking can be defined as a stream of bits embedded in a data file. Digital watermarking has two basic concepts-first is content protection and second is copyright management. In this paper, two most commonly us...

A Review on Digital Watermarking Techniques, Applications and Attacks

In today's digital world, in every field there is massive use of digital contents. Digital documents can be copied and scattered easily to large numbers of people without any cost. People can download audio, image and video files, and they can share them with friends and they can influence or change their original contents. Due to this, there is more probability of copying of such digital information. So, there is an urgent need of prohibiting such illegitimate copyright of digital media. Digital watermarking (DWM) is the dominant solution to this problem. This paper aims to provide an exhaustive survey of digital watermarking techniques especially focuses on image watermarking types and its applications in today's world.

Digital Watermarking: A Tutorial Review

The growth of high speed computer networks and that of Internet, in particular, has explored means of new business, scientific, entertainment, and social opportunities. Ironically, the cause for the growth is also of the apprehension -use of digital formatted data. Digital media offer several distinct advantages over analog media, such as high quality, easy editing, high fidelity copying. The ease by which a digital information can be duplicated and distributed has led to the need for effective copyright protection tools. Various software products have been recently introduced in attempt to address these growing concerns. It is done by hidding data (information) within digital audio, images and video files. One way such data hidding is digital signature, copyright label or digital watermark, that completely characterizes the person who applies it and, therefore, marks it as being his intellectual property. Digital Watermarking is the process that embeds data called a watermark into a multimedia object such that watermark can be detected or extracted later to make an asertion about the object. Watermarking is either "visible" or "invisible". Although visible and invisible are visual terms watermarking is not limited to images, it can also be used to protect other types of multimedia object. This work is a tutorial review of the digital watermarking techniques appreared in the literature.
