StampR сертифицира произведения без да съхранява оригиналните файлове

StampR uses an architecture based on the privacy-by-design principle, which allows authorship and creation time to be certified without storing the original digital content in the system.

When you use the service, the file is processed locally on the user’s device. A cryptographic SHA‑256 hash is calculated as a unique digital fingerprint that identifies the work. Only this hash value is sent to the server; the original file is never uploaded, viewed or stored.

This approach provides strong evidence of existence and integrity while minimising the risk of content leakage. It is particularly suitable for source code, patent concepts, unreleased literary and musical works, sensitive drawings and internal documents.

If the user wishes, StampR can also operate in a mode where the original file is stored as additional evidence, but this is not a prerequisite for the legal value of the certificate.
