Research and Development in Type 1 IMS

 

According to current studies carried out e.g. by the Gartner Group, the Yankee Group and the Radicati Group, the market of IMS is expected to grow fast at least until 2008. Turnaround prognosis starts from 748 million US $ in 2004 and varies from 3 billion US $ in 2007 to 10.2 billion US $ in 2008. The expected turnaround is for IMS of type 1.

In general we observe two technical directions of development of IMS type 1: 

  1. Account management systems are integrating more and more in integrated solutions like enterprise resource planning (ERP). In addition to the described integration into human resource planning systems further integrations can be observed, e.g., customer relationship management systems (CRM).

  2. Integration of more organisations while distributing the administration:    
    To distribute the account administration concerning some personal data to different administrators, federated identity management systems can be used. With federated identity management systems and meta-directories (e.g. DirX by Siemens) implementations to support authentication, authorisation and accounting in groups of trusted organisations are becoming more and more available.

 

Scientific research concerning type 1 IMS currently is directed towards further development of advanced, centralised authentication and authorisation services. One example is the “Configurable Internet Directory and Authentication Service” (CIDAS) developed by F.-L. Holl et al. Basing on an LDAP server, CIDAS offers among others different levels of authorisation depending on the chosen type of authentication and anonymous authentication against an application server. Currently an early prototype of the planned Open Source implementation is available.
