Digital security system, method and program
First Claim
1. A digital security system comprising:
- abdominal pressure signal acquiring means configured to acquire an abdominal pressure signal from an abdominal pressure sensor that detects an abdominal pressure of a person, the abdominal pressure signal acquiring means is configured to acquire a respiration signal from a respiration sensor that detects breathing of the person;
abdominal pressure signal extracting means configured to generate an abdominal pressure signal with suppressed influence of respiration by subtracting the respiration signal from the abdominal pressure signal;
abnormality determining means configured to use the abdominal pressure signal to determine whether or not an abnormality exists; and
control means configured to report an abnormal situation when the abnormality determining means determines that the abnormality exists,wherein the abnormality determining means is configured to determine that that the abnormality exists either when the abdominal pressure signal is consistent with a predetermined abdominal pressure pattern or when the abdominal pressure signal is in a predetermined range.

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.
