Abstract

A processor may process a video feed of a monitored area. The processing may include attempting to decrypt the video feed using a temporally-varying digital rights management key in a state corresponding to a time at which the encrypted video feed was received and encountering a decryption error during the attempting. The processing may include comparing the video feed with an output feed from a secondary sensor to determine that at least one object is indicated in the monitored area by the output feed and not visible in the video feed. The processor may indicate a problem with the video feed. For example, the processor may indicate that the encrypted video feed has been altered prior to the receiving of the encrypted video feed due to the decryption error and/or that the video camera is malfunctioning due to the at least one object being not visible in the video feed.

Claims20

Dependent claims

A monitoring system comprising:

a video camera configured to generate a video feed of a monitored area;
a secondary sensor configured to generate an output feed of the monitored area;
a processor in communication with the video camera and the secondary sensor;
and
a non-transitory memory in communication with the processor, the memory being configured to store instructions that, when executed by the processor, cause the processor to perform processing comprising:
analyzing the output feed to determine that at least one object is present in the monitored area, the analyzing comprising comparing the output feed with a known empty map of the monitored area to detect the at least one object as an object not within the map and determining a location of the at least one object relative to the map;
analyzing the video feed to attempt to detect the at least one object in the video feed, the analyzing comprising applying at least one object recognition algorithm to at least the portion of the image depicting the location of the at least one object;
based on the analyzing of the video feed, failing to detect the at least one object in the video feed due to the at least one object recognition algorithm outputting an indication that the location of the at least one object is empty;
and
locking access to at least one location due to the at least one object not being detected in the video feed.

7 more elements

A fraud detection system comprising:

a monitoring system comprising:
a video camera configured to generate a video feed of a monitored area;
a monitoring processor in communication with the video camera;
a monitoring transceiver in communication with the monitoring processor;
and
a non-transitory monitoring memory in communication with the monitoring processor, the monitoring memory being configured to store instructions that, when executed by the monitoring processor, cause the monitoring processor to perform processing comprising:
receiving, by the monitoring transceiver, a digital rights management key that changes over time;
encrypting the video feed using the digital rights management key;
and
transmitting, by the monitoring transceiver, the encrypted video feed;
and
a playback system comprising:
a playback processor;
a playback transceiver in communication with the playback processor;
and
a non-transitory playback memory in communication with the playback processor, the playback memory being configured to store instructions that, when executed by the playback processor, cause the playback processor to perform processing comprising:
receiving, by the playback transceiver, the encrypted video feed;
receiving, by the playback transceiver, the digital rights management key in a state corresponding to a time at which the encrypted video feed was received;
attempting to decrypt the encrypted video feed using the digital rights management key received by the playback transceiver;
encountering a decryption error during the attempting;
and
indicating that the encrypted video feed has been altered between the transmitting of the encrypted video feed and the receiving of the encrypted video feed due to the decryption error.

19 more elements

A method of detecting video feed problems, the method comprising:

receiving, at a processor, a video feed of a monitored area;
performing processing, by the processor, on the video feed, the processing comprising at least one of:
attempting to decrypt the video feed using a temporally-varying digital rights management key in a state corresponding to a time at which the encrypted video feed was received and encountering a decryption error during the attempting;
and
comparing the video feed with an output feed from a secondary sensor to determine that at least one object is indicated in the monitored area by the output feed and not visible in the video feed;
and
indicating, by the processor, a problem with the video feed, the indicating comprising at least one of:
indicating that the encrypted video feed has been altered prior to the receiving of the encrypted video feed due to the decryption error;
and
indicating that the video camera is malfunctioning due to the at least one object being not visible in the video feed.
