An approach for storing and maintaining data is disclosed. One or more sensors are provided for detecting unauthorized access to a first non-volatile storage. If unauthorized access to the first non-volatile storage is detected, then the data on the first non-volatile storage is deleted by overwriting the data on the first non-volatile storage with a predetermined value so that the data cannot be recovered. The first non-volatile storage is registered with a registration authority to provide authentication of the data maintained on the first non-volatile storage.

DETAILED DESCRIPTION According to one aspect of the invention, a method is provided for storing data on a storage unit in a manner that allows modification of the data only if a tamper signal is detected that indicates unauthorized physical access to the storage unit.
The method includes detecting the tamper signal and in response to detecting the tamper signal, deleting the data stored on the storage unit by overwriting the data with a specified value, and preventing any data from being written to the storage unit and preventing any data from being read from the storage unit.
According to another aspect of the invention, a data storage unit for storing and maintaining data is provided.
The data storage unit comprises a first non-volatile storage device and a processing unit communicatively coupled to the first non-volatile storage device.
The processing unit is configured to allow modification of the data stored on the first non-volatile storage device only if a tamper signal is detected that indicates unauthorized physical access to the first non-volatile storage device.
The processing unit is also configured to in response to detecting the tamper signal, delete the data stored on the first non-volatile storage device by overwriting the data stored on the first non-volatile storage device with a specified value, and prevent any data from being written to the first non-volatile storage device and prevent any data from being read from the first non-volatile storage device.
