Confidential information memory apparatus, erasing method of confidential information, and erasing program of confidential information

An erasing method of confidential information carried out by a confidential information memory apparatus storing confidential information, the method comprising:

• by a sensor related record memory,
• storing a plurality of sensor related records, in each of which at least one sensor is made related to confidential information specified as an erasing target and a detecting condition to be satisfied by the at least one sensor is specified, including at least two sensor related records of which the confidential information specified as the erasing target are different with each other;
• by a confidential information memory,
• storing a plurality of pieces of confidential information;
• and
• by a processing unit,
• inputting a detection signal from a sensor shown by the sensor related records stored in the sensor related record memory,
• extracting a sensor related record which satisfies all of the detecting conditions based on the detection signal inputted, and
• selectively erasing the confidential information specified as the erasing target shown by the sensor related record extracted from the plurality of pieces of confidential information stored in the confidential information memory.

A non-transitory computer-readable storage medium encoded with an erasing program of confidential information to have a confidential information memory apparatus being a computer including a confidential information memory and a sensor related record memory perform a method comprising:

• storing a plurality of sensor related records, in each of which at least one sensor is made related to confidential information specified as an erasing target and a detecting condition to be satisfied by the at least one sensor is specified, including at least two sensor related records of which the confidential information specified as the erasing target are different with each other in the sensor related record memory;
• storing a plurality of pieces of confidential information in a confidential information memory;
• and
• inputting a detection signal from a sensor shown by the sensor related records stored in the sensor related record memory, extracting a sensor related record which satisfies all of the detecting conditions based on the detection signal inputted, and selectively erasing the confidential information specified as the erasing target shown by the sensor related record extracted from the plurality of pieces of confidential information stored in the confidential information memory.
