தடயங்கள் பேசும்! நாங்கள் மொழிபெயர்ப்போம்!!
Kriyavan Cyber Forensic Service in Madurai is a private digital forensics lab serving all of Tamil Nadu. We examine phones, WhatsApp chats, CCTV, photos, emails and computers, and deliver hash-verified, court-ready reports with BSA 2023 Section 63(4)(c) certificates, signed by a certified digital forensic examiner. The court decides admissibility; we make sure the evidence is examined properly.
மொபைல், வாட்ஸ்அப் சாட், சிசிடிவி, புகைப்படம், மின்னஞ்சல் — முறையாகப் பரிசோதித்து, 63(4)(c) சான்றிதழுடன் நீதிமன்றத்தில் சமர்ப்பிக்கத் தகுந்த அறிக்கை. மதுரை கிரியாவன் ஆய்வகம்.
Please don't send evidence on WhatsApp — just tell us what you have and the case stage. The examiner replies personally.
If your WhatsApp chats are challenged in court
— you need a forensic examiner.
We export the chats from the phone in our lab, hash them on arrival and certify the output under Section 63(4)(c) — not a screenshot.

Signed by the examiner who produced the record on our own lab equipment — the requirement the Supreme Court set in Arjun Panditrao (2020) — and tied to a verifiable hash chain.

A screenshot alone is easy to challenge. A proper chat export, hashed on receipt, examined on the original device where possible and accompanied by a Section 63(4)(c) certificate is far harder to dispute. Whether it is admitted is the court's decision.
It is the certificate under the Bharatiya Sakshya Adhiniyam 2023 (successor to Section 65B) that accompanies an electronic record. It must be signed by a person responsible for the device that produced the output — at Kriyavan, the examiner who operated the lab workstation.
No. Identifying a person needs lawful process through the police and the platform. We examine and document the records you already hold so they are preserved correctly for court.
Yes — written expert opinion and, where the court requires, oral testimony in Tamil Nadu and Puducherry, or by video where permitted. Every opinion rests on our own examination.
Yes, across Tamil Nadu and Puducherry. Intake is on WhatsApp and hand-over of records is arranged per case.
