Given the large number of user profiles available on the internet, the safeguarding becomes problematic. This paper presents a technic of safeguard and of implicit construction of the user profile that is part of a distributed backup approach and a formal construction method using the user behavior as a source for predicting implicitly its need. Keywords: User profile, Formal context, Personalization, Information research systems. 1 INTRODUCTION The generalists information research models are based on the assumption that the user need is represented by its request, thus, for a given query, the information research systems (IRS) return the same results list, however users have different information needs. Work is now moving towards a broader definition of the user. It is a stream of research that seeks the implementation of usercentric systems by representing him by a profile. The Analysis of user behavior reveals particular importance. Indeed, it is with full knowledge of how the user will elaborate his strategies for information research, that it will be possible to propose to him the significant information for his research. The modelisation of profiles and how to adapt them to different users who do not have a clear idea of the .
