Which of the following is a method to provide secure recording in testimony?

Using confidence recording techniques is a method that enhances the security and reliability of testimony recordings. This approach is designed to ensure that the integrity of the recorded data is maintained throughout the process. Confidence recording often involves the use of specified practices and protocols that may include proper identification of the parties involved, timestamping during the recording, and the use of secure storage solutions. These methods help prevent alteration or tampering of the recordings, thereby safeguarding the accuracy of the testimony.

In contrast, other methods mentioned do not contribute to secure recording. Outdated equipment may not function reliably or may lack necessary features for secure data handling. Group recordings can introduce complexity and may make it difficult to attribute specific statements to individuals, increasing the risk of inaccuracies. Solo transcription, while useful for documentation purposes, does not inherently provide the same level of security and integrity for the original recordings.
