Research And Implementation On Uniform Accessing Of User-Info In Moblie Internte

With the maturity of 3G and development of broadband mobile network, the convergency trend of mobile communications and Internet Technologies is becoming increasingly clear, and the mobility, personality, openness of Mobile Internet (MI) have made it become a global concern. However, the constrains of the mobile terminal and communication network, such as the inconvenience use of the mobile terminal to register services, the privacy of the use of the service, and especially the great negative effects of disclosing risk of user's private infomation all block the further development of the Mobile Internet greatly. All of things described above make the centralized storing and uniform accessing of user information in the Mobile Internet become more and more meaningful.The paper first introduces the research background and gives a brief overview of the related knowledge of Mobile Internet and the traditional Identity Management system. Then a new Identity Management system named MIDM (Mobile Identity Management) which is based on user information centralized storing and uniform accessing is proposed. Compared to other information management platforms, MIDM is based on the store and use of user information and takes the trusted mobile telecommunication operators as the management platform of user infomation, and does research on the privacy level of user information and trusted level of SP, and then quantify them to finish the authentication of the accessing process form SP to user information storing in the platform. Then the paper analyzes the basic architecture and main relevant elements of MIDM and presents a new multi-Attributes-based Dynamic Access control Model (ADAC) to complete the uniform accessing process in MIDM. At last, based on the proposed theoretical model,this paper gives the design and implementation of the user information uniform accessing function in the MIDM.
