chain of custody
Step-by-step explanation:
It is an important aspect of forensic evidence and is used to ensure the integrity and reliability of the evidence. The chain of custody is established and documented through a series of steps, including the collection, transportation, storage, and analysis of the evidence. Each step in the chain of custody must be carefully documented, and the evidence must be handled and stored in a manner that preserves its integrity and prevent contamination or tampering. The chain of custody must also be clearly established in order to demonstrate the authenticity and reliability of the evidence in a legal setting.
