Proximity based authentication using bluetooth
View Patent ↗Techniques for securing communications between fixed devices and mobile devices. A mobile device management server mediates communications between the fixed device and mobile device. The mobile device management server enrolls mobile devices and then assists with pairing the mobile devices to fixed devices in an out-of-band manner. This enrollment, coupled with out-of-band pairing, improves the speed and security of authenticating communication between fixed and mobile devices. If the mobile device has appropriate capabilities, the mobile device management server may request that the mobile device obtain and verify biometric data from a user prior to enrollment and performing authentication procedures.
1. A method for securing communications between a first device and a mobile device, comprising:
performing an enrollment operation that comprises verifying enrollment credentials received from the mobile device;
requesting that the mobile device verify first biometric data at the mobile device;
receiving an indication from the mobile device that the first biometric data was verified at the mobile device;
obtaining a first security token associated with the mobile device and a first security certificate associated with the mobile device from the mobile device;
obtaining a second security token associated with the first device and a second security certificate associated with the first device from the first device; and
performing an out-of-band pairing between the first device and the mobile device based on the first security token, the first security certificate, the second security token, and the second security certificate, the out-of-band pairing also being based on receiving the indication from the mobile device that the first biometric data was verified at the mobile device.
2. The method of claim 1 , further comprising causing the mobile device to perform an authentication operation in response to receiving the indication that the first biometric data was verified at the mobile device.
3. The method of claim 1 , wherein performing the enrollment operation further comprises:
causing the mobile device to verify second biometric data; and
in response to receiving an indication from the mobile device that the second biometric data is verified, storing an indication that the mobile device is enrolled with biometric data.
4. The method of claim 3 , wherein performing the enrollment operation further comprises generating a security certificate associated with the second biometric data in response to receiving the indication from the mobile device that the second biometric data is verified.
5. The method of claim 1 , wherein the first biometric data comprises one of fingerprint data and retinal scan data.
6. The method of claim 1 , wherein performing the out-of-band pairing comprises:
transmitting the first security token and the first security certificate to the first device; and
transmitting the second security token and the second security certificate to the mobile device.
7. The method of claim 1 , wherein:
the first device comprises a private first device, and
the out-of-band pairing is performed in response to verifying the enrollment credentials.
8. The method of claim 7 , further comprising:
in response to verifying the enrollment credentials, transmitting a first media access control address (MAC address) associated with the first device to the mobile device and transmitting a second MAC address associated with the mobile device to the first device.
9. The method of claim 7 , further comprising:
performing a scan for mobile devices, by the first device, via a local wireless network;
receiving, via the local wireless network, a response to the scan from the mobile device to the first device, the response including the second MAC address;
determining that the first device has previously received the second MAC address; and
performing an authentication task between the first device and the mobile device, via the local wireless network.
10. The method of claim 1 , wherein:
the first device comprises a public device, and
the out-of-band pairing is performed in response to an identification inquiry from the public device that includes a first media access control address (MAC address) of the mobile device for identification.
11. The method of claim 10 , further comprising:
performing a scan for mobile devices, by the first device, via a local wireless network, to receive the first MAC address from the mobile device;
in response to verifying the enrollment credentials, transmitting a second MAC address that is associated with the first device to the mobile device;
receiving the first MAC address;
performing the out-of-band pairing in response to determining that the first MAC address corresponds to the mobile device, which is enrolled; and
performing an authentication task between the first device and the mobile device, via the local wireless network.
12. A system for securing communications between a first device and a mobile device, comprising:
a mobile device management server configured to:
perform an enrollment operation that comprises verifying enrollment credentials received from the mobile device;
request that the mobile device verify first biometric data at the mobile device;
receive an indication from the mobile device that the first biometric data was verified at the mobile device;
obtain a first security token associated with the mobile device and a first security certificate associated with the mobile device from the mobile device;
obtain a second security token associated with the first device and a second security certificate associated with the first device from the first device; and
perform an out-of-band pairing between the first device and the mobile device based on the first security token, the first security certificate, the second security token, and the second security certificate, the out-of-band pairing also being based on receiving the indication from the mobile device that the first biometric data was verified at the mobile device.
13. The system of claim 12 , wherein the mobile device management server is further configured to:
in response to receiving the indication that the first biometric data was verified at the mobile device, cause the mobile device to perform an authentication operation.
14. The system of claim 12 , wherein the mobile device management server is configured to perform the enrollment operation by:
causing the mobile device to verify second biometric data; and
in response to receiving an indication from the mobile device that the second biometric data is verified, storing an indication that the mobile device is enrolled with biometric data.
15. The system of claim 14 , wherein the mobile device management server is further configured to perform the enrollment operation by:
generating a security certificate associated with the second biometric data in response to receiving the indication from the mobile device that the second biometric data is verified.
16. The system of claim 12 , wherein the first biometric data comprises one of fingerprint data and retinal scan data.
17. The system of claim 12 , wherein the mobile device management server is configured to perform the out-of-band pairing by:
transmitting the first security token and the first security certificate to the first device; and
transmitting the second security token and the second security certificate to the mobile device.
18. The system of claim 12 , wherein:
the first device comprises a private device, and
the mobile device management server is configured to perform the out-of-band pairing in response to verifying the enrollment credentials.
19. The system of claim 18 , wherein the mobile device is further configured to:
in response to verifying the enrollment credentials, transmit a first media access control address (MAC address) associated with the first device to the mobile device and transmit a second MAC address associated with the mobile device to the first device.
20. A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:
