Abstract

Multimedia messaging services (MMS) enrich the user experience and create a major new source of revenue for network operators as well as for content and service providers. The capability of multimedia messaging service center (MMSC) in delivering different types of digital content, such as music, images, and video, presents a huge opportunity for its use in mobile e-commerce. But in current e-commerce, separate logins are needed to access different service providers. This limitation prevents MMS to closely cooperate with other service providers. The Liberty Alliance standards are intended to solve the problem of signing on repeatedly for each service provider. The Liberty Alliance defines the specifications to share identity information across service providers. However, these specifications have not been integrated into MMS. This thesis is concerned with the design of a system wherein the MMS works with other service providers, MMS acting as Identity provider. When the user federates his/her account in MMS with the account at any of the service providers, he/she can send a service request to a service provider (SP) without being asked for his/her password with the service provider, and at the same time can have access to the MMS from web page of that service provider. To demonstrate the feasibility of this design, a simulation system in compliance with Liberty single sign-on and federation protocol is developed in Java using a single service provider based on Liberty identity federation framework (ID-FF)
