A Digital Watermarking Base On C#.NET Framework

Information hiding refers to the process of information transmission,storage-specific information contained within a module, other modules do not need thisinformation, it is unknowable. Digital watermarking technology is an importantresearch focus of the direction of the field of information security, information hidingtechniques, has played an important role in protecting the copyright of digitalpublications.As vigorously promote military information, digital publications as one of theimportant part, how to efficiently and effectively protect the copyright of the mediaworks from infringement, demand for digital watermarking system gradually prominent.In this paper, the research and learn communication theory techniques as the algorithm,C#. NET Framework development platform, the development of a stable and efficientIn this paper, from digital watermark technology overview describes the basis ofthe digital image, Turbo coding in C#NET Framework applications in four areas, threelevels described watermarking system development from a theoretical basis, algorithmdesign, system development.Digital watermark embedding and extraction algorithms from the digital imageRGB three components to start, combined with human visual characteristics, draw oncommunication diversity technology, in the different components embedded in differentstrength of the watermark information, and combined with the data transmission framestructure mode, design and development of a watermark embedding and extractionalgorithm.Transform algorithm in the watermark information, this paper is a communicationerror correction code technology, especially in conjunction with the Turbo codestructure, combined with the scrambling code and interleaved code, designed a robust,robust and strong noise resistance watermarking algorithm.C#.NET Framework-based characteristics of system development, from C#tostart digital image computing data amount and more, the complexity of thecomputational complexity of the problem, compared draw on the C language and C++ language of the pointer, developed based on memory method of digital imageprocessing algorithms.
