Ubiquitous systems will integrate computers invisibly and unobtrusively in everyday objects. Information will appear in new forms, i.e. data will be catched from single or multi-sensor devices and will be used for context extraction. New location-based services will be adapted to user preferences. For this the ubiquitous system needs to know user profiles, likings, and habits. As the user moves these information have to be sent to the new location of the user. Either the user carries her data on wearable or portable computers or the ubiquitous environment takes responsibility for transporting them. The amount of new devices and services makes an efficient use by centralized systems very difficult. The idea presented in this paper is that a virtual reflection of the user represented by a mobile agent accompanies her in the ubiquitous environment. Mobile agents offer a possibility to encapsulate information of a person and her preferences and perform location-based services of the ubiquitous system in the name of the user. Because of the personal data security and privacy are major concerns of such an agent system. This paper describes a ubiquitous mobile agent system named UbiMAS which has security extensions to provide high protection of agents and significant personal data. UbiMAS is used in a smart office environment with smart doorplates.
