Technology Behind the Record
Modern cryptographic technology designed to make digital records independently verifiable.
SHA-256 Digital Fingerprint
A cryptographic hash represents the exact digital file you registered.
When you register a work, APR computes a SHA-256 fingerprint of the file itself. Change even a single character, pixel, frame, or byte and the fingerprint changes. The fingerprint does not reveal the contents of your file — it simply represents it.
Trusted Timestamping
Timestamps help establish when the cryptographic record existed.
APR uses APR Timekeeper, its independent cryptographic timestamp authority, to anchor every fingerprint with a secure, RFC-3161 compliant timestamp. APR Timekeeper uses a dual-provider pipeline (FreeTSA + TrueTimestamp) to ensure reliability and long-term durability. It timestamps the fingerprint, returns a cryptographic token and serial number, records the timestamp in APR's evidence registry, and creates a permanent audit trail.
Independent Verification
Verification should not require simply trusting a database entry.
Anyone holding a file can compare it against the registered fingerprint. If the fingerprints match, the file corresponds to the registered digital record. If they do not match, the file is different. That comparison can be performed using the cryptographic evidence rather than relying solely on APR.
Verify a RegistrationAPR + APR Timekeeper
APR provides the creator-focused registration and verification experience. APR Timekeeper provides cryptographic proof infrastructure supporting independently verifiable digital records.
A SHA-256 fingerprint tied to the exact file you registered.
APR Timekeeper anchors every fingerprint with an RFC-3161 timestamp using a dual-provider pipeline for reliability and long-term durability.
Verification uses cryptographic evidence from APR Timekeeper, not just a database lookup.
For Technical Users
APR is an independent evidence and registration service. It does not replace registration with the U.S. Copyright Office, does not determine copyright ownership, and does not guarantee that any party will accept a particular record as evidence.
Submission Tracking Technology (Optional Feature)
APR uses the same timestamping and verification principles to maintain a protected record of your outreach.
Every submission is logged, timestamped, and tied to your certificate, creating a defensible history of where your work was sent and when.
This feature is optional — you can use APR for protection only.
Protection for creators in the AI era
APR proves what existed first, so you can document your originality when AI-generated or derivative work appears.
