Abstract
Techniques of controlling access to a resource involve selecting an authentication scheme for authenticating a user based on an environmental context in which the user is requesting access to the resource. Along these lines, the access control server receives application usage data from a user and separates the data into current environmental factors and current usage factors. In response, the access control server compares the current environmental factors to expected environmental factors for each of multiple predefined environmental contexts. Based on measures of closeness between the current and expected environmental factors, the access control server computes a familiarity score indicative of whether the request to access the resource is recognizable within the particular environmental context. The access control server then selects, based on the familiarity score, an authentication scheme from a choice of multiple such schemes by which to authenticate the user before granting the user access to the resource.
