Progressive authorization of information based on confidences of user identities

Abstract:

Systems and techniques are disclosed for progressive authorization of information. One of the methods includes obtaining information from a user device indicating a user identity of a user operating the user device, the user device being in communication with a content server. A confidence associated with the user identity of the user is determined. Requests from the content server for profile information associated with the user identity are responded to, such that authorization levels of requested profile information are determined to be satisfied based on the confidence. Upon a positive determination, use of the requested profile information is granted. Upon a negative determination, prompts for additional identifying information are provided on the user device.
