Once the validation information is stored in the database, the data may not be altered in any way. The validation system database must be encrypted or password-protected and should possess a non-alterable user audit trail to prevent unauthorized access. Further, the normal operation of any device that holds ticket information shall not have any options or methods that may compromise ticket information. Any device that holds ticket information in its memory shall not allow removing of the information unless it has first transferred that information to the database or other secured Component(s) of the validation system.
