Abstract
Progressive authentication is generally employed to establish the authenticity of a user, such as a user of a computing device, or a user that wants to access a proprietary data item, software application or on-line service. This can entail inputting authentication factors each of which corresponds to one or multiple attributes associated with the user, or historical patterns of one or more attributes associated with the user, or both, and a confidence level that estimates a reliability of the factor. Sensor readings captured by one or more sensors are also input. Each sensor senses a user attribute and are used to quantify each authentication factor confidence level. An overall confidence level is established based at least in part on a combination of the individual confidence levels. A user is then designated as being authentic whenever the established overall confidence level exceeds a prescribed authentication level. This process can be continuous with the overall confidence level being continually updated.
