Abstract

A computer system receives an authentication request from a user device and determines a determined device identification from a set of received device attributes. When the device is properly authenticated, the computer system generates an authentication token that is signed by the determined device identification and returns the authentication token to the user device. When the computer system subsequently receives a service request with an authentication token and a plurality of device attributes for a protected resource from a user device, the computer system determines a derived device identification from some or all of the received device attributes. When a signed device identification of the authentication token and the derived device identification are equal, the apparatus continues processing the service request. Otherwise, the service request is rejected.

Claims

1. An apparatus comprising:

at least one memory device;

at least one processor coupled to the at least one memory device and configured to perform, based on instructions stored in the at least one memory device;

receiving a service request for a protected resource from a first user device, wherein the service request includes a plurality of device attributes and an authentication token;

determining a derived device identification from a first attribute set contained in the plurality of device attributes;

when a signed device identification of the authentication token and the derived device identification are equal, continue processing the service request; and

when the signed device identification is not equal to the derived device identification, rejecting the service request.

2. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

when the signed device identification and the derived device identification are equal, sending a challenge to the first user device for authentication information; and

only when the authentication information is determined to be correct, servicing the service request.

3. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

receiving an authentication request from a second user device;

determining a determined device identification from a set of device attributes;

when a desired level of authentication for the second user device is achieved, generating a generated authentication token, wherein the generated authentication token is signed by the determined device identification; and

returning the generated authentication token to the second user device.

4. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

when a signed device identification of the authentication token and the derived device identification are equal, challenging the first user device for authentication information until a degree of authentication is achieved.

5. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

extracting an extracted authentication level from the authentication token; and

processing the service request based on the extracted authentication level.

6. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

receiving an expired authentication token with the service request;

challenging the first user device for authentication information; and

when the authentication is determined to be correct, determining a new expiration time;

inserting the new expiration time in an updated authentication token;

signing the updated authentication token with the signed device identification; and

returning the updated authentication token to the first user device.

7. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

determining a changed device identification from a different attribute set of the plurality of device attributes;

signing a changed authentication token with the changed device identification; and

returning the changed authentication token to the first user device.

8. The apparatus of claim 7, wherein the at least one processor is further configured to perform:

receiving an expired authentication token with the service request;

challenging the first user device for authentication information; and

when the authentication is determined to be correct, initiating the determining the changed device identification, the signing, and the returning when receiving an expired authentication.

9. The apparatus of claim 1, wherein the at least one processor is further configured to perform:

when the signed device identification is not equal to the derived device identification, generating an notification about an authentication failure for the first user device.

10. The apparatus of claim 3, wherein the at least one processor is further configured to perform:

when the determined device identification conflicts with an assigned device identification of another user device, altering the set of device attributes; and

recalculating a recalculated device identification, wherein the recalculated device identification is different from the assigned device identification of the other user device.

11. The apparatus of claim 3, wherein the set of received device attributes includes a browser attribute and a hardware attribute.

12. A computer-assisted method for authenticating a first user device the method comprising:

receiving an authentication request and at least one device attribute from the first user device;

determining a first determined device identification from a first set of device attributes;

when a desired level of authentication for the first user device is achieved, generating a generated authentication token, wherein the generated authentication token is signed by the first determined device identification; and

returning the generated authentication token to the first user device.

13. The method of claim 12, further comprising:

determining a second determined device identification for a second user device from a second set device attributes, wherein the first set and the second set differ by at least one device attribute.

14. A computer-assisted method for authenticating a user device, the method comprising:

receiving a service request for a protected resource from a user device, wherein the service request includes a plurality of device attributes and a received authentication token;

determining a derived device identification from an attribute set contained in the plurality of device attributes;

when a signed device identification of the received authentication token and the derived device identification are equal, continue processing the service request; and

when the signed device identification is not equal to the derived device identification, rejecting the service request.

15. The method of claim 14 further comprising:

when the signed device identification and the derived device identification are equal, sending a challenge to the user device for authentication information; and

only when the authentication information is determined to be correct, servicing the service request.

16. The method of claim 14 further comprising:

when a signed device identification of the received authentication token and the derived device identification are equal, challenging the user device for authentication information until a degree of authentication is achieved.

17. The method of claim 14 further comprising:

extracting an extracted authentication level from the received authentication token; and

processing the service request based on the extracted authentication level.

18. A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed, cause a processor at least to perform operations comprising:

receiving a service request for a protected resource from a user device, wherein the service request includes a plurality of device attributes and an authentication token;

determining a derived device identification from a first attribute set contained in the plurality of device attributes;

when a signed device identification of the authentication token and the derived device identification are equal, continue processing the service request; and

when the signed device identification is not equal to the derived device identification, rejecting the service request.

19. The non-transitory computer-readable storage medium of claim 18, wherein the computer-executable instructions, when executed, cause the processor to perform:

receiving an authentication request from the user device;

determining the derived device identification from the plurality of device attributes;

when a desired level of authentication for the user device is achieved, generating a generated authentication token, wherein the generated authentication token is signed by the derived device identification; and
