ABSTRACT- In recent years, digital media are widely popular, their security related issues are becoming greater importance. Watermarking is the process of hiding digital data in a carrier signal. Embedding a digital signal such as audio, video or image with the information which cannot be removed easily is called digital watermarking. Digital watermarking mainly used to verify the authenticity, integrity of the carrier signal or to show the identity of its owners. In this paper, we present a survey on various digital watermarking techniques. This paper mainly concentrates a detailed survey of all watermarking techniques on image watermarking types in today’s world.
Index Terms – Digital watermarking, spatial domain, Least Significant Bit (LSB), Frequency domain, Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), and Discrete Fourier Transform (DFT).
INTRODUCTION
The term digital watermarking was first emerged in 1993, Tirkel introduce two watermarking techniques to hide the watermark data in the images [1].In recent years digital media are gaining widely popular, and their security related issues are becoming greater importance. The protection and
been developed rapidly. Digital media brings about conveniences to the people, because it is easy to be processed. At the same time, it enables the illegal attackers to attack the works. For the protection of data there has been growing interest in developing effective techniques to discourage the unauthorized duplication of digital data. Digital watermarking is the process of embedding information into a digital signal in a way that is difficult to remove. Protection of digital multimedia content has
The rapid invention going in internet usage has resulted in the media ownership and attention towards intellectual property rights among internet users. In this paper, a Multiwavelet Transform (MWT) based video encoding is proposed. Video watermarking is the practice of inserting an encode information known as the watermark, into an original video in an imperceptible approach. The watermark converts or represents information that can protect the watermarked video, typically identifying the source
AN EFFICIENT DATA CONCEALMENT APPROACH BASED ON PIXEL PAIR MATCHING AND ENCRYPTION TECHNIQUE
Abstract - This paper proposes a data hiding method using adaptive pixel pair matching and data encryption approach for secret data communication. Steganography is the science of hiding secret data in plain sight within cover data so that it can be securely transmitted over a network. The idea of PPM is to use the values of pixel pair as a reference coordinate, and search a coordinate in the neighborhood
proposed technique is powerful.
[35], DivjotKaurThind, et.al In this paper a ultra-modern digital video watermarking scheme is proposed which mixes DWT and SVD in which watermarking is achieved within the HF sub band and then various forms of attacks have been carried out. The watermark object has been embedded in each body of the original video. Since in each frame, watermark is embedded and it offers robustness towards attacks.

The industry is investing to deliver audio, image and video data in electronic form to customers, and broadcast television companies, major corporations and photo arc hivers are converting their content from analogue to digital form. This movement from traditional content, such as paper documents, analogue recordings, to digital media is due to
Security of information becomes one of the most important factors of information technology and communication because of the huge rise of the World Wide Web and the copyrights laws. Cryptography was originated as a technique for securing the confidentiality of information. Unfortunately, it is sometimes not enough to keep the contents of a message secret, it may also be necessary to keep the existence of the message secret and the concept responsible for this is called steganography [2]. Steganography

The hackers take benefit of the stolen non-public and crucial pictures to meet their dangerous and unethical intentions. The photograph statistics theft can be used to defame someone at the internet by means of posting the illegal and unacceptable photographs of that individual (internet user.
