Authentic Digital Evidence for Legal Professionals
Tamper-proof photo evidence with SHA-256 hashing and atomic timestamps. Admissible digital evidence for attorneys, paralegals, and law enforcement.
AI-Generated Evidence Is Contaminating Legal Proceedings
Courts across the world are facing an unprecedented challenge: AI-generated photos are being submitted as evidence in civil and criminal cases. Deepfake technology can now fabricate scene photos, injury documentation, and property damage images that are virtually indistinguishable from authentic captures.
A single piece of fabricated evidence can derail an entire case, waste thousands of billable hours, and undermine the integrity of the judicial process. Traditional metadata analysis is no longer sufficient — AI tools can replicate EXIF data, GPS coordinates, and device signatures with alarming accuracy.
Legal professionals need a verification standard that establishes an unbroken chain of custody from the moment a photo is captured. Without cryptographic proof of authenticity, any digital photo is now presumed suspect.
Cryptographic Chain of Custody for Digital Evidence
Proof.show creates an immutable chain of custody at the exact moment of capture. Every photo receives a SHA-256 cryptographic hash — the same standard used in federal digital forensics — paired with an atomic clock timestamp synchronized via NTP. This means the exact second a photo was taken is independently verifiable, not reliant on an editable device clock.
The live-only capture requirement eliminates gallery uploads entirely, ensuring no AI-generated image can enter the verification pipeline. Combined with screen photo detection (moire pattern analysis) and liveness checks, Proof.show produces evidence that meets the highest standards of digital authenticity for courtroom use.
Capture Evidence Live
Take a photo directly through Proof.show — no gallery uploads allowed, eliminating AI-generated image injection.
Hash & Timestamp
SHA-256 fingerprint and NTP atomic timestamp are generated instantly, creating an unbreakable chain of custody.
Present Verified Proof
Share the Proof Code with any party — opposing counsel, judges, or insurers can verify authenticity instantly at proof.show/v.

How It's Used
Frequently Asked Questions
Proof.show generates SHA-256 cryptographic hashes and atomic timestamps that provide strong evidence of photo authenticity. While admissibility depends on jurisdiction and case specifics, the cryptographic proof and chain-of-custody documentation are consistent with federal digital evidence standards (FRE 901).
Photos are hashed at the moment of live capture — before they ever leave the device. Any modification, even a single pixel change, produces a completely different hash. The atomic timestamp is fetched from independent NTP servers, not the device clock, making time manipulation impossible.
Yes. Any party can enter the 8-character Proof Code at proof.show/v to instantly verify the photo's authenticity, timestamp, and hash. No account or special software is required — verification is public and instant.
