In the era of high-speed Internet, 4G, broadband and MMS; Digital data in the form of text, images, videos and audios can be easily copied and distributed around the world. For protection against copyrights and illegal uses; The concept of watermarking techniques become popular. Logos on TV channels, special tags like time stamp on video playback and weak image in logo form behind document texture are some of the visible watermark examples that are frequently used in The real world. This is like printing on paper. The digital watermark technique allows you to embed an image or any hidden data in an original image without changing the perspective of the original (true) image. Various methods in the blind watermark technique do not require the original image, although some of the image properties may be affected. The frequency domain technique is robust and highly secure.
The digital watermark is a process for embedding information hidden in digital multimedia data by some method of signal processing, the information is generally unobservable, which is only drawn by special detector or reader with an author key. Digital watermark techniques gain advantage of the insensitive perceptual organs of the human eye with the part of the brain that manages it and idleness in the digital signal that looks the eye. The digital watermark does not alter the basic feature of the digital data and uses the value. A digital watermark system consists of two parts, watermark inlay and watermark detection. In Watermark's inlay algorithm, the symmetric key or public key is used to embed the watermark in the original carrier information and then obtain a secret carrier. Watermark detection algorithm uses the corresponding key to detect or recover the secret carrier watermark, without key decryption, attackers hard to find and check secret carrier watermark. If they try to do so then the original data is distorted. The watermark can be random digital sequence, digital identification data, text and image or audio, etc ....
The advancement of media systems frameworks and the explosion of the rapid correspondence system has demoralized and cushioned the media content provider, ie creators, distributors to allow the circulation of their file in the system environment. The watermark has been convened as a device for the insurance of the intellectual property right (IPR) of the interactive media substance. In view of their advanced nature, view and sound reports can be copied and broadcast effectively. In this context, it is vital to add a framework work for the security of copyright. Assurance against duplication and substance verification. The watermark is extremely valuable in the paper examination, since it can be used for dating, size recognition, trademarks and areas We are living in the data period in which billions of bits of information Is made in each part of a second and with the emergence of Web, creation and transmission of advanced information (images, videos and sound recordings, computer stores and libraries, distributed web) has been developed on numerous occasions. The innovation of computerized correspondence, similar to web innovation, resists different problems identified with the protection and security of information. Security methods are required as a result of unauthorized access to unauthorized information. In this way, it is important to ensure in web innovation.
