Abstract: Methods, systems and computer program products to allow a user to identify himself to a content provider, without having to explicitly perform a log in process or other identification and authentication process. By manipulating a user device such as a remote control, a profile of the user may be constructed, where the profile includes a representation of how the individual user typically manipulates the device. The profile includes a feature vector that is a function of the number of times that individual buttons are pressed. The construction of the feature vector may be viewed as a training or learning phase. Once the profile and feature vector are constructed, the user's interaction with the device in a subsequent session may be captured and compared with the profile. This may allow identification of the user, in turn allowing content to be tailored in a manner specific to this user.
