Provided are a digital security system, method and program that are capable of reporting an emergency in terms of security without allowing a suspicious person to become aware of the reporting, even when the report is made right in front of the suspicious person, and to do so while also improving reliability by preventing report errors and failures. The digital security system is provided with: an abdominal muscle pressure signal acquisition unit (101) that acquires an abdominal muscle pressure signal from an abdominal muscle pressure sensor (10) which detects the abdominal muscle pressure of a user, and that also acquires a respiratory signal from a respiratory sensor (20) that detects the respiration of the user; an abdominal muscle pressure signal extraction unit (102) that cancels out the respiratory signal component from the acquired abdominal muscle pressure signal and extracts an abdominal muscle pressure signal for which the impact of respiration is suppressed; an abnormality determination unit (112) that determines whether there is an abnormality on the basis of the abdominal muscle pressure signal from which the respiration signal component has been cancelled out; and a warning transmission unit (203) that reports an abnormal state on the basis of the abnormal state occurrence determination results. |
