Data protecting system and method for protecting data

A data secret protecting system comprising:

• data holding means received in a case for holding data;
• distortion detecting means disposed in said case for detecting a distortion value of said case to produce a detected distortion value;
• temperature measuring means received in said case for measuring a temperature value of said case to produce a measured temperature value;
• distortion correcting means connected to said distortion detecting means and to said temperature measuring means for correcting, utilizing said measured temperature value, said detected distortion value to calculate corrected value of said detected distortion value;
• distortion comparing means connected to said distortion detecting means for comparing said corrected value of said detected distortion value with a reference distortion value to produce a compared distortion signal when said corrected value of said detected distortion value is greater than said reference distortion value;
• and
• data erasing means connected to said data holding means and to said distortion comparing means for erasing said data held in said data holding means when said data erasing means is supplied with said compared distortion signal.

A data secret protecting method comprising the steps of:

• holding data in a case, said case having inner surfaces
• detecting a distortion value of said case with a distortion detector disposed on less than all of said surfaces at a discrete location inside said case to produce a detected distortion value;
• comparing said detected distortion value with a reference distortion value to produce a compared distortion signal when said detected distortion value is greater than said reference distortion value;
• and
• erasing, in response to said compared distortion signal, said data.
