Challenge-response user authentication based on information collected by internet of things devices

Abstract:

Approaches presented herein enable challenge-response authentication of a user based on information captured by devices associated with the user. Specifically, in one approach, a plurality of devices associated with the user that each dynamically track and store on-device data points over a period of time are identified. A request initiated by a party claiming to be the user is received to authenticate the party as the user. An authentication question is generated in a natural language, the answer to which is a data point selected from data points on at least one device of the plurality, wherein the selected data point is discoverable by viewing data points on the at least one device. The requesting party is prompted to find the data point by presenting the authentication question to the requesting party. In the case that the requesting party returns the answer, the requesting party is authenticated as the user.
