Abstract

Provided are a digital security system, method and a program that prevent erroneous reports and failed reports to improve reliability, while allowing reporting an abnormal situation in security, even in front of a suspicious person, without the suspicious person'"'"'s awareness. The digital security system comprises an abdominal pressure signal acquisition unit (101) that acquires an abdominal pressure signal from an abdominal pressure sensor (10) for detecting a user'"'"'s abdominal pressure and acquires a respiration signal from a respiration sensor (20) for detecting the user'"'"'s breathing, an abdominal pressure signal extraction unit (102) that subtracts the respiration signal component from the acquired abdominal pressure signal to extract an abdominal pressure signal with suppressed influence of respiration, an abnormality determination unit (112) that determines whether it is abnormality based on the abdominal pressure signal from which the respiration signal component has been subtracted, and an alarm sending unit (203) that reports an abnormal situation based on a determination result as being the occurrence of an abnormal situation.

Claims

1. A digital security system comprising:

abdominal pressure signal acquiring means for acquiring an abdominal pressure signal from an abdominal pressure sensor for detecting an abdominal pressure of personnel and for acquiring a respiration signal from a respiration sensor for detecting breathing of said personnel to which these sensors are fitted;

abdominal pressure signal extracting means for subtracting the respiration signal component from the acquired abdominal pressure signal to extract an abdominal pressure signal with suppressed influence of respiration;

abnormality determining means for determining whether it is abnormality based on the abdominal pressure signal extracted by the abdominal pressure signal extracting means; and

control means for reporting an abnormal situation according to the abnormality determination result by the abnormality determining means.

2. The digital security system according to claim 1, wherein the abnormality determining means determines that it is abnormality if the abdominal pressure signal extracted by the abdominal pressure signal extracting means is consistent with a predetermined abdominal pressure pattern.

3. The digital security system according to claim 1, wherein the abnormality determining means finally determines that it is abnormality if the abdominal pressure signal extracted by the abdominal pressure signal extracting means is repeatedly determined that it is abnormality in a predetermined range.

4. The digital security system according to claim 1, wherein the control means makes a different report according to the abnormality determination result of the abnormality determining means.

5. The digital security system according to claim 1, comprising:

positional information acquiring means for detecting existing positions of a plurality of communication terminals, and acquiring positional information of the communication terminals; and

jurisdiction retaining means for retaining a jurisdictional district for receiving an emergency telephone call where a building under security exists, wherein

the control means refers to the jurisdiction retaining means in response to the abnormality determining means having determined that it is an abnormal situation, and if any of the plurality of communication terminals exists in the jurisdictional district, reports preferentially to the communication terminal existing in the jurisdictional district.

6. The digital security system according to claim 1, wherein the reporting means transmits an e-mail message and an image.

9. A tangible non-transitory computer-readable storage medium having a program stored therein, wherein the program configures a computer to perform as the digital security system according to claim 1.

7. A digital security method comprising:

an abdominal pressure signal acquiring step of acquiring an abdominal pressure signal from an abdominal pressure sensor for detecting an abdominal pressure of personnel and of acquiring respiratory information from a respiration sensor for detecting breathing of said personnel to which these sensors are fitted;

an abdominal pressure signal extracting step of subtracting the respiration signal component from the acquired abdominal pressure signal to extract an abdominal pressure signal with suppressed influence of respiration;

an abnormality determining step of determining whether it is abnormality based on the abdominal pressure signal extracted by the abdominal pressure signal extracting step; and

a control step of reporting an abnormal situation according to the abnormality determination result by the abnormality determining step.
