Digital Copyright Protection Scheme Based On JUNA Lightweight Digital Signatures

With the rapid development of today’s society, the digital technology of ourcountry and the world develops more and more quickly, it brought great change inPeople’s Daily life, make our life more and more digital, people can share and spreadthrough the network, for example, documents, video, audio, and image, etc., but in theprocess of frequent network transmission. Some counterfeiters copy these resources,has made some good work to appear the phenomenon of piracy, seriously violatedlegal the legitimate interests of copyright owner,and it has great influence for theculture and the development of the network, so the digital copyright protectiontechnology research is particularly important.Traditional digital copyright protection are invisible watermark such as images,words, or common digital signature, it causes the watermark embedding process verycomplex. JUNA lightweight digital signature as visible watermarking, will be thedominant way to make the digital identity of16characters together in the right bottomcorner of the original works, without considering embedded location choice,meanwhile, in simplifying the process of digital copyright protection, it guarantees thesecurity of the system. The code of JUNA lightweight digital signature is only80bits,and the length of the signature code converted to32hexadecimal characters can onlyfor16characters, the length of the signature code can become shorter, it implementsthe system of low waste, low consumption and low cost requirements, combined withthe concept of cloud computing, this paper designed a digital copyright protectionscheme based on JUNAlightweight digital signature.Through the research on the field of digital copyright protection, first, this paperanalyzes the requirements of digital copyright protection system, includingrequirements analysis of each module function in the system, such as copyrightregistration function module, distributed function module, copyright tracking functionmodule and copyright authentication module; Second, by the specific requirementsanalysis of the four main functions, according to these requirements, from the systemsoftware architecture, the research object, data storage and digital signature algorithm,four aspects, designs the overall train of thought, a system and design the systemmodel, describes the corresponding overall plan; Again, it will put forward concretedescription of the program, according to the specific function modules, is described inalgorithm described in the form; Finally, this system compared with the existingcopyright protection system and the analysis, mainly from piracy and infringement,identification of copyright ownership, system security and ease of use four aspectscarries on the concrete analysis, fully shows the advantage of this system, can be avery good solution to solve the existing problems in the system of copyright protection.
