In recent years there has been a fast grow of various electronic services.Each service requires specif-ic credentials for authenticating and authorizing user ac-cess or specific subset of user's personal information for transactions the service offers.Such a situation causes problems with remembering multiple,service-specific authentication data,with controlling user's personal data spread across different services-problems with managing user's identities.This paper is an overview on Identity Management(IdM).It introduces basic terms connected with IdM,shows current and emerging appli-cation areas,enumerates the most important IdM activi-ties,describes the most representative identity manage-ment specifications and frameworks and at the end,it points out important problems in identity management which need to be addressed in the near future.
