What forensic technique should be used to ensure the admissibility of evidence when authorities are collecting evidence for fraud?

The correct answer emphasizes the importance of maintaining the chain of custody when collecting evidence for fraud cases. Chain of custody refers to the process of handling and documenting evidence from the moment it is collected until it is presented in a court of law. This procedure is critical because it establishes the integrity and authenticity of the evidence, ensuring that it has not been altered, tampered with, or contaminated during the investigation.

In legal contexts, evidence must be demonstrably reliable to be considered admissible. By maintaining a clear and thorough chain of custody, investigators can provide a reliable record of who handled the evidence, when it was handled, and the conditions under which it was stored. This documentation is essential for proving the evidence's integrity in court and for bolstering the prosecution's case against an individual accused of fraud.

While the other options have their own significance in the realm of digital forensics and security, they don't directly address the requirements for evidence admissibility in a courtroom setting. For instance, order of volatility relates to the sequence in which evidence should be collected based on its volatility, and data recovery addresses retrieving lost or deleted data. Non-repudiation refers to assuring that someone cannot deny the validity of their signature or the sending of a message, which is
