Method and system for contextual access control
Described embodiments provide systems and methods for contextual confidence scoring-based access control. The systems and methods can include one or more processors configured to receive a request from the client device to access an item of content. The one or more processors can select a first subset of authentication techniques. The authentication techniques identifiable with a score. The one or more processors can determine that a sum of the scores of the selected first subset of the authentication techniques exceeds a threshold. The one or more processors can transmit, to the client device, one or more authentication requests utilizing the selected first subset of authentication techniques. The one or more processors can provide, responsive to successful authentication by the client device, access to the item of content to the client device.
