Riffyns' audit trail addresses the following section of 21 CFR:
11.10 (e) Use of secure, computer-generated, time-stamped audit trails to independently record the date and time of operator entries and actions that create, modify, or delete electronic records. Record changes shall not obscure previously recorded information. Such audit trail documentation shall be retained for a period at least as long as that required for the subject electronic records and shall be available for agency review and copying.
Riffyn's audit trail tracks all changes made to a process/experiment in a format that cannot be edited. Full details of changes made to a process/experiment can be viewed in the audit trail.
