Cryptography And DRC Visualization In Digital Copyright Work Management Based On DOA

Information security faces new challenges in present open data environment,although the increasingly mature digital copyright protection technology has ensured the security of digital works to certain extent.As per the issue of data ownership,there is still unauthorized access and unlicensed use because of unclear division of rights and responsibility,and the security of digital works is still threatened.Data Oriented Architecture(DOA)explores an authorization mechanism in data applications,and proposes the concept of data ownership.This paper explores a kind of authorization mechanism in data application,and puts forward the concept of data ownership.In this paper,the AES symmetric encryption algorithm and RSA asymmetric encryption algorithm are deeply studied,and a cryptographic procedure of combining AES decryption of fast speed with RSA algorithm of high security,is applied to the authority confirmation and authorization process in the digital copyright works management under the DOA architecture.The main research contents of this paper are as follows:(1)The constituent elements of DOA and the basic structure of each module are analyzed in depth,and the process of authorization and authorization between data producers,data owners and data users are studied in the DOA logic.(2)The mathematics and encryption process of AES and RSA algorithm are studied.Through the analysis of the efficiency of encryption and decryption,the authority confirmation and authorization scheme of AES and RSA is determined,and is applied to the encryption of the works in the management of digital copyright works under the DOA framework,and to the processes of authorizing by author to the distributor,and authorizing by publisher to the user.(3)Based on DOA architecture,the processes of authorization,confirmation and distribution of digital copyright works are realized.The interface between the client and the platform is designed,and data registration center(Data Registration Center,DRC)is initially established to manage the information and the key of the digital copyright works,and the copyrighted works are stored in the third parties.(4)The performance of the process of confirmation and authorization of digital copyright works are analyzed in the paper,and systematic stress tests both on single and distributed structures are carries out.The research results and innovation of this paper are as follows:(1)The DRC data registration center has been designed to record the addresses and Hash values of the works in the DRC,which ensures the uniqueness and non change of the transaction process of the digital works,and tracks the transaction status of the works.(2)The data samples in DRC can be used to generate visual views,and the users and authors' interest in different works and the agent preference of the publishers are analyzed through those data.
