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
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
applications to mix sound, images, and video and to interact with large amounts of information (e.g., in e-business, distance education, and human-machine interface). 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
Hiding Messages Using Motion Vector Technique In Video Steganography P.Paulpandi1, Dr.T.Meyyappan,M.sc.,M.Phil.,M.BA.,Ph.D2 Research Scholar1, Associate professor2 Department of Computer Science & Engineering, Alagappa University,Karaikudi. Tamil Nadu,India. Abstract- Steganography is the art of hiding information in ways that avert the revealing of hiding messages.Video files are generally a collection of images. so most of the presented techniques on images and audio can be applied to video
pixel benefits are changing in spatial area 1.9 Applications Of Image Encryption In the present world lot of multimedia data is exchanged on internet and the percent of image data in that is highest. So we need to securely transmit that and this can be achieved by Image encryption. • Image encryption has applications in internet communication, multimedia systems, medical and military imaging systems. • It is used in Digital Watermarking & Stenography. • It has been used by government and military to
Abstract An effective method for encryption of images using magnitude and phase manipulation of the image with the help of a carrier image is described. Although it involves traditional methods like magnitude and phase encryption, the novelty of this work lies in the fact that a private key as well as a carrier image is used for encryption. An image to be encrypted and a carrier image is chosen and row wise one dimensional DFT is taken for both the image. This is used for obtaining the row wise magnitude
would it?” - Albert Einstein (1879 - 1955) An image is a 2 dimensional representation of a 3 dimensional scene. A Digital Image is a graphical representation of an object. Digital Image Processing abbreviated as DIP is the manipulation of digital image by a processor. Image Registration is one of the techniques used in Digital Image Processing. Registration refers to merging and fusion of 2 or more data. Image Registration is a fundamental step in all image analysis tasks in which we find mapping for
David Maccarone Sheng Mao Security Issues with Databases 1. Current state of database security A database is a system that is specialized to manage data in a computer application system. Data has many forms, such as text, digital, symbols, graphics, images and sound. The database systems are integral components of current and future command, communication, control and intelligence information systems. (Lunt, 1992, p. 253) Databases are used widely in our life. Because of databases
