[Feat]: 4.2 ISO 27037: The Standard for Digital Evidence

[viru0909-dev]

• To further establish trust, Nyay-Setu should align its evidence handling protocols with
  ISO/IEC 27037, which provides guidelines for the identification, collection, acquisition, and preservation of digital evidence. This involves implementing rigorous Chain of Custody logs. Every interaction with a piece of
  evidence—upload, view, download, share—must berecorded as an immutable transaction.

• The current Blockchain implementation creates a "hash anchor" for the file , which is a strong start.
  However, to fully comply with forensic standards, the system must ensure that once a case is marked
  "Sub Judice" or "Filed" the records become WORM (Write Once, Read Many) compliant. This prevents even the uploader from modifying or deleting the evidence, preserving the integrity of the judicial record. The audit trail itself should be tamper-evident, potentially by hashing the log entries in a linked chain (a "blockchain-within-the-database") to ensure that the history of the evidence is as secure as the evidence itself.
