A digital real security system, method and program reliably report the occurrence of an emergency situation in real time. The digital real 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, and a storage unit (105) that stores a normal-time number of breathing times and abdominal pressure pattern of the user detected by the abdominal pressure signal acquisition unit (101), and an abnormality determination unit (112) matches a number of breathing times and abdominal pressure pattern detected by the abdominal pressure signal acquisition unit (101) to that user's normal-time number of breathing times and abdominal pressure pattern stored in the storage unit (105), and determines whether it is abnormality based on the match result.
