Audit Trail (WHO)
The audit trail is a form of metadata that contains information associated with actions that relate to the creation, modification or deletion of GXP records. An audit trail provides for secure recording of life-cycle details such as creation, additions, deletions, or alterations of information in a record, either paper or electronic, without obscuring or overwriting the original record.(TR80)

Data Integrity
The assurance that the data remains complete, consistent, accurate, trustworthy, and reliable throughout its life cycle. Maintaining data integrity is crucial for ensuring the validity of AI-driven insights, supporting regulatory compliance, and enabling reliable decision-making in pharmaceutical manufacturing.

Data Integrity (FDA)
Refers to the completeness, consistency, and accuracy of data. Complete, consistent, and accurate data should be attributable, legible, contemporaneously recorded, original or a true copy, and accurate (ALCOA).(TR80) (TR84)

Data Integrity (MHRA)
The degree to which data are complete, consistent, accurate, trustworthy, reliable and that these characteristics of the data are maintained throughout the data life cycle. The data should be collected and maintained in a secure manner, so that they are attributable, legible, contemporaneously recorded, original (or a true copy) and accurate. Assuring data integrity requires appropriate quality and risk management systems, including adherence to sound scientific principles and good documentation practices.(TR80) (TR84)

True Copy (FDA)
21 CFR 211.180(d) requires records to be retained "either as original records or true copies such as photocopies, microfilm, microfiche, or other accurate reproductions of the original records". Electronic copies can be used as true copies of paper or electronic records, provided the copies preserve the content and meaning of the original or raw data, which includes associated metadata and the static or dynamic nature of the original records.(TR80)(TR84)

True Copy (MHRA)
A copy (irrespective of the type of media used) of the original record that has been verified (i.e., by a dated signature or by generation through a validated process) to have the same information, including data that describe the context, content, and structure as the original.(TR80)(TR84)
Source:
True Copy (WHO)
A true copy is a copy of an original recording of data that has been verified and certified to confirm it is an exact and complete copy that preserves the entire content and meaning of the original record including, in the case of electronic data, all essential metadata and the original record format as appropriate.(TR80)(TR84)
