Digital Forensics and Evidence Service: Expert Report and Court Validity

Quick answer: Emails, messages, logs and deleted files can decide a dispute, but digital evidence is valid in court only if collected properly. However striking the content, evidence that was altered by touching the original, has no hash or lacks a documented chain of custody can be rejected. DSET handles forensics without ever breaking the chain of custody, to international standards (ISO/IEC 27037) and Turkish procedure. Expert help: +90 536 662 38 09.

The golden rule, do not touch the original

Digital data is fragile, even opening a file changes its access time. So rule one is to never work on the original media. The expert takes a forensic image with a write blocker and works only on that copy, preserving the original as first acquired so the other side cannot claim tampering.

Hash, mathematical proof of integrity

How do you prove evidence never changed? With a hash (e.g. SHA-256), a data fingerprint computed at acquisition and recomputed at each step, same value means not a single bit changed. See hash verification.

Chain of custody

An unbroken record of who held the evidence, when and how, documented from acquisition to court, defined by ISO/IEC 27037.
