Which practice is recommended to ensure that delivery records remain tamper-proof?

Using secure electronic systems with audit trails is highly recommended for ensuring that delivery records remain tamper-proof. This approach enhances the integrity and security of the records by utilizing technology that tracks and logs every change made to the documents. Audit trails provide a clear historical record of access and modifications, making it easy to identify any unauthorized attempts to alter the information. This system not only safeguards against tampering but also aids in compliance and accountability, as it can confirm who accessed or modified a record and when.

In contrast, options that involve allowing multiple employees to sign the same record can introduce uncertainty regarding accountability, as it becomes less clear who is responsible for the accuracy of the record. Keeping handwritten logs in an unlocked cabinet poses significant security risks, as these logs could easily be altered, lost, or destroyed without an auditable record of changes. Lastly, sharing documentation publicly would compromise confidentiality and security, opening it up to tampering by unauthorized individuals. Therefore, utilizing a secure electronic system with an audit trail is the most effective method for maintaining the integrity of delivery records.
