Biometric notification system
The present invention provides a biometric notification system for selectively sending messages to interested recipients. In various embodiments, message trigger criteria, interested recipients, and message content may vary depending upon, among other things, the service being provided.
1. A site biometric notification system (“BNS”) with facial recognition and related services, the system comprising:
plural digital video cameras (C 1 . . . C n ) for monitoring respective zones (Z 1 . . . Z n ) at a first site and a network that interconnects the plural digital video cameras with a data processing system including a processing facility and a database facility;
the cameras for acquiring video frames from the respective zones, at least one video frame including a respective first content from which a first facial feature set can be derived;
a database of the database facility includes plural cases and each case identifies a person by linking a name, a second facial feature set, and a case group;
for each video frame, a comparison of the first facial feature set from C x , Z x with the second facial feature sets; and,
where the second facial feature set matches the first facial feature set, a message that includes the name of a person and an indication of Z x is sent to interested recipients indicated by the case group.
2. The system of claim 1 wherein each case identifies a person by linking a name, a second facial feature set, a case group, and a case location alert, the case location alert matching Z x .
3. A site biometric notification system (“BNS”) with facial recognition for identifying persons in zones from which they are excluded, the system comprising
plural fixed digital video cameras (C 1 . . . C n ) for monitoring respective zones (Z 1 . . . Z n ) at a first site and a network that interconnects the plural digital video cameras with a data processing system including a processing facility and a database facility;
a video frame acquired by camera Cx in zone Zx, the video frame including a first content from which a first facial feature set can be derived; and,
where some persons are not excluded from Z x , a database of the database facility limited to plural cases of persons excluded from Zx, each case in the database identifying a person by linking a name with a second facial feature set;
wherein a comparison of the first and second facial feature sets that produces a match causes a message to be sent to a receiving device, the message including the person named in the matched case and Z x .
4. A site biometric notification system (“BNS”) with facial recognition for identifying persons in zones from which they are not excluded:
plural digital video cameras (C 1 . . . C n ) for monitoring respective zones (Z 1 . . . Z n ) at a first site and a network that interconnects the plural digital video cameras with a data processing system including a processing facility and a database facility;
a video frame acquired by camera Cx in zone Zx, the video frame including a first content from which a first facial feature set can be derived; and,
where some persons are excluded from Z x , a database of the database facility limited to plural cases of persons not excluded from Zx, each case in the database identifying a person by linking a name with a second facial feature set;
wherein a comparison of the first and second facial feature sets that fails to produce a match causes a message to be sent to a receiving device, the message including the person named in the unmatched case and Z x .
