The stored data in the device is protected in a number of ways from corruption or interference both physically and in hardware and software. An 8Mb on-board Flash memory, which does not need to be battery backed, will retain the data during power interruption. The saved data can be encrypted which ensures that it will not be tampered with to meet to the most stringent requirements of internal or external auditors. There is also an internal audit trail that logs al changes to the unit and can identify who made the changes and when.
In addition to password protection and to prevent unauthorized access of the removable memory, the media door includes a lock. To make the unit even more secure, the ability to fit a tamperproof seal is provided. A provision is made for reading encrypted data into standard PC spreadsheet applications. This allows off-line analysis and archiving while maintaining data integrity.
