MONITOR INFORMATION PROCESSING DEVICE AND METHOD, AND PROGRAM AND RECORDING MEDIUM
First Claim
1. A monitor information processing device that detects illicit movement from one of a public area and a controlled area separated by a door to the other, on a basis ofauthentication result information indicating permission of movement from one of the public area and the controlled area to the other, generated as a result of a decision as to whether or not to permit the movement, the decision being based on identification information presented by the person attempting the movement,door open/close information indicating a state of the door, the opening and closing of which are controlled on a basis of the authentication result information, andencoded video data generated by encoding a video signal obtained by imaging a vicinity of the door,the monitor information processing device comprising:
- a data quantity measurement unit for measuring a data quantity, for each predetermined period, of the encoded video data; and
a comparison/determination unit for detecting the illicit movement on a basis of the door open/close information, the authentication result information, and a length of an interval during which the data quantity for each predetermined period measured by the data quantity measurement unit is continuously greater than a predetermined data quantity threshold.

Abstract
Illicit movement is detected on the basis of authentication result information (D3), door open/close information (D4), and changes in the quantity of encoded data (D2) of a video image of the vicinity of a door (9). An illicit movement is found to have occurred when the length of an interval during which the data quantity (D5) for each period is continuously greater than a threshold, or an integral (D80) of the data quantity (D5) exceeds a threshold, while the door is in an unlocked state. It is thereby possible to detect illicit entry into a controlled area with high precision, without decoding the encoded video data from the monitoring camera, and without carrying out complex image processing.
