Abstract

A system for passive driver identification comprises an input interface and a processor. The input interface is configured to receive a collection of face data from a vehicle event recorder. The processor is configured to 1) determine a set of face data of the collection of face data that is associated with a trip; 2) determine a first album associated with the trip, wherein the set of face data associated with the trip is similar to face data of other trips in the first album, and wherein the set of face data associated with the trip is dissimilar to face data of a set of trips in a second album; and 3) assign an identifier that associates the trip to the first album.

Claims

1. A system for passive driver identification, comprising:

an input interface configured to;

receive a collection of face data from a vehicle event recorder; and

a processor configured to;

determine a set of face data of the collection of face data that is associated with a trip;

determine a first album associated with the trip;

wherein the set of face data associated with the trip is similar to face data of other trips in the first album; and

wherein the set of face data associated with the trip is dissimilar to face data of a set of trips in a second album; and

assign an identifier that associates the trip to the first album.

2. A system as in claim 1, wherein the input interface is further configured to receive is images.

3. A system as in claim 1, wherein the input interface is further configured to receive time information.

4. A system as in claim 1, wherein the input interface is further configured to receive vehicle identifier information.

5. A system as in claim 1, wherein the input interface is further configured to receive location information.

6. A system as in claim 1, wherein the input interface is further configured to receive ignition information.

7. A system as in claim 6, wherein the ignition information is used to determine a start time and a stop time for a trip.

8. A system as in claim 1, wherein a face data of the collection of face data comprises a set of numeric quantities calculated from a face image that is used to compare face images.

9. A system as in claim 1, wherein a probability is estimated that a first person in a first image is the same as a second person in a second image.

10. A system as in claim 1, wherein the processor is further configured to associate the identifier with a driver.

11. A system as in claim 1, wherein determining the first album associated with the trip comprises determining an existing album associated with the trip.

12. A system as in claim 11, wherein determining the existing album associated with the trip comprises determining a probability that the trip belongs to each existing album.

13. A system as in claim 1, wherein the identifier is assigned to the album based at least in part on a verified association database.

14. A computer program product for passive driver identification, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a collection of face data from a vehicle event recorder;

determining, using a processor, a set of face data of the collection of face data that is associated with a trip;

determining a first album associated with the trip;

wherein the set of face data associated with the trip is similar to face data of other trips in the first album; and

wherein the set of face data associated with the trip is dissimilar to face data of a set of trips in a second album; and

assigning an identifier that associates the trip to the first album.

16. A system as in claim 14, wherein the verified association database stores a driver identifier associated with one or more of the following:

a verified face data, a driver RFID, or a driver biometric.

15. A method for passive driver identification, comprising:

receiving a collection of face data from a vehicle event recorder;

determining, using a processor, a set of face data of the collection of face data that is associated with a trip;

determining a first album associated with the trip;

wherein the set of face data associated with the trip is similar to face data of other trips in the first album; and

wherein the set of face data associated with the trip is dissimilar to face data of a set of trips in a second album; and

assigning an identifier that associates the trip to the first album.
