Abstract
A method of accessing secure data on a user device, wherein authentication access of the user device is not available, including: receiving a request from a requester to access secure data in the user device; receiving authentication input from a user; authenticating a data input from the user using a control token; and providing access to secure data to the requester.
Claims18
A method of accessing secure data on a user device, wherein authentication access of the user device is not available, comprising:
- receiving a request from a requester to access secure data in the user device;
- receiving an authentication input from a user;
- authenticating the authentication input from the user using a control token;
- and
- providing access to the secure data to the requester;
- and
- wherein the control token comprises:
- a second factor for authenticating the authentication input when the user device is fully operational;
- and
- a single factor for authenticating the request when the user device is not fully operational.
A method of accessing secure data on a user device by a requester device, wherein the user device is in a low power mode and is incapable of performing local biometric authentication, comprising:
- sending a request to the user device to access secure data in the user device;
- receiving data from the user device including biometric verification data retrieved from a secure element of the user device using power harvested from the requester device;
- receiving a biometric input from a verifier device, where a user provides a biometric input to the verifier device;
- comparing, by the requester device on behalf of the user device, the biometric input from the verifier device with the biometric verification data;
- and
- accessing the secure data of the user when an input from the verifier device matches the biometric verification data.
A method of accessing secure data on a user device by a requester device, wherein the user device is in a low power mode and is incapable of performing local biometric authentication, comprising:
- receiving a request from the requester device to access secure data in the user device;
- sending data to the requester device including biometric verification data retrieved from a secure element of the user device using power harvested from the requester device;
- receiving proof of a biometric input into a verifier device from the requester device, where the user provides a biometric input to the verifier device;
- verifying the proof of a biometric input;
- and
- sending the secure data of the user to the requester device when the proof of a biometric input is verified.
