Research And Application Of Digital Watermarking Algorithm For Embedded Platform

At the present time,the society has entered the era of mobile Internet,especially in the great trend that China has begun to deploy the base stations of the fifth-generation mobile networks,the communications using digital technology will become more and more frequent.In this context,the security of digital information has naturally become a real problem to be solved.Digital watermarking technology provides an effective and feasible solution.In the first place,this thesis explains the structure of digital watermarking technology,the various technical features and application scenarios,and the limitations of the technologies.In order to address these limitations and problems,this thesis proposes an algorithm that combines artificial intelligence technology with traditional digital watermarking algorithm.Based on the idea of classical digital watermarking algorithm,a digital watermarking algorithm combining the convolutional neural network and generative adversarial network model is proposed.Secondly,in this thesis,the theoretical principle,implementation process and training process of the algorithm are expounded in detail;then a set of performance evaluation system is proposed;and then the algorithm and scheme are tested;the results are analyzed in detail at the end of the chapter.Experiments show that the proposed algorithm not only has certain resilience to the existing conventional attack methods,but also can generate corresponding resilience through supplementary training if a new attack mode emerges in the future.On the basis,this thesis has developed a digital watermark management system that can run on the embedded platform combining the digital watermarking algorithm.The system can obtain the required content as close as possible,solve the congestion of the Internet,and ensure the confidentiality and integrity of image data at the same time.At first,this thesis has analyzed the users' specific requirements;then,this thesis has carried out a system design based on these requirements;and then,this thesis describes the environment and configuration of the system in detail;and then,this thesis complete the system functions,and elaborate the specific implementation method of the system core modules;finally,this thesis shows the operation of the system and tests the whole system.Through system testing,we can know whether the requirements of the actual application are met.In addition,the system test can provide the basis for the future improvement of the system.The main research work of this thesis is the development of digital watermarking algorithm,which improves the shortcomings of this field at home and abroad.It also provides new ideas and methods for the implementation of digital watermarking algorithm and system application in embedded platform.
