P26-electronic-evidence-certificate.html" style="color:#3D61D2; text-decoration:underline;">Bharatiya Sakshya Adhiniyam 2023, Section 63 (and Section 65B of the Indian Evidence Act 1872). But it is important to be precise: e-Dex helps you prepare a strong, well-documented record. Admissibility always remains the decision of the court, and nothing here is legal advice. For internal audit and governance, the value is the same — a defensible, repeatable, independently checkable record that the data is unaltered.

Conclusion

"We have a backup" is a hope; "we can prove this backup is unaltered" is evidence. By pairing baseline-vs-recompute hashing with a sealed, signed, timestamped and registered certificate, e-Dex — the Digital Evidence Integrity Suite gives audit, compliance and data-governance teams a record they can stand behind. If you are responsible for archived or migrated data, try the Backup & Audit Integrity Certificate and turn your backups into something you can actually demonstrate.

Frequently Asked Questions

Does having a backup prove the data is unaltered?

No. A backup only proves a copy exists at some location. It cannot show the content is byte-for-byte identical to the original, because storage can degrade, migrations can transcode files, and edits or ransomware can change data silently. Proving the data is unaltered needs cryptographic hash verification, not just a backup catalogue.

What is baseline-vs-recompute hash verification?

It is a two-stage check. When you trust the data, you compute a hash (such as SHA-256) of every file and record it as a baseline fingerprint. Later, you re-read the same files and recompute their hashes, then compare. If all values match, the data is unaltered; if any differ, you know exactly which file changed.

What does a Backup & Audit Integrity Certificate contain?

It captures the backup job details (source, archive location, run and operator), the baseline and recomputed file hashes across multiple algorithms, a clear verified-vs-failed verdict per item, a declaration of what was checked, and signature blocks. e-Dex also adds a SHA-256 integrity seal, an optional digital signature, a trusted timestamp, and a register number.

Is this only for police or court use?

No. While the certificate uses a court-ready format, it is built mainly for enterprise audit, compliance and data-governance teams. Common uses include long-term data-retention checks, system-migration sign-off, internal investigations, and handing auditors a signed, timestamped verdict instead of an informal claim that the backup is fine.

Can the certificate be re-verified later without internet?

Yes. Because the SHA-256 seal, optional signature and timestamp travel inside the PDF, any reviewer can re-verify the certificate offline in e-Dex's Evidence Viewer. This confirms the signature is valid, the document is unmodified, and the timestamp token is sound, with no internet connection and no third-party tool required.
