The Research And Design Of Music Copyright Protection Encryption System

In recent years,with the popularity and development of mobile Internet technology and wireless communication technology,gradually digital music replaces the traditional music,becoming the main ways for users to listen to music.But changes have come to the model of music spread by Internet Industry.Due to music copyright issues in China since entities had not attached,domestic music market led to counterfeit.In case of record industry profits are eroded,the music works are more convenient to copy and spread.So copyright protection of digital music is becoming more and more important,which not only has a theoretical value,but also can bring considerable commercial value.The content of this dissertation is the studying and design based on encrypting music copyright protection system.Relevant technical standards about this system are the digital copyrights management system standards,the highest market share of smart phone operating system which is the Android operating system,and web server.This dissertation introduces the basics of the above technologies,a variety of encryption algorithm and based on them concludes with a new digital encryption algorithm for digital mobile music media and architecture which based on network server and the smartphone Android platform,it finally implement the encrypting system based on music copyright protection system.This dissertation firstly use sequential extraction method,cyclic shift method and select the encryption method to optimize Arnold chaotic encryption algorithm based on the traditional Arnold chaos algorithm and the feature of mobile digital music.So the Arnold chaos algorithm has simple structure,small amount of computation,high effect and high security features.Secondly,improved Arnold chaotic encryption algorithm is the music copyright protection encryption algorithm encryption system,and using the needs analysis,dividing system modules,this dissertation designs and implements the content server database,data processing interface and Android client.And finally,the content interface connect with Android client together through the Internet,into one unified system.The results of research implement the system infrastructure design and digital music searching,purchasing,managing,download and play on the design.Through the xampp server and AVD virtual environment on the windows platform,the system is functioning properly,which implement the design of system and functional requirements of the user.
