Questions & Answers

As answered by people managing StampR.eu and StackMail.

Which are the primary technologies used for building your product?

StampR.eu's answer

Web application, SHA-256 cryptographic hashing, electronic timestamping, PDF certificate generation, QR-based verification and server-side certificate verification infrastructure.

What makes your product unique?

StampR.eu's answer

StampR combines an authorship declaration for a specific digital work with the SHA-256 fingerprint of that exact file version and a verifiable electronic timestamp. The result is a certificate that documents what was certified, who declared authorship, and when that specific version was recorded. Certificates include a unique identifier and can be checked through StampR’s verification workflow.

Why should a person choose your product over its competitors?

StampR.eu's answer

StampR is designed for people who want a simple way to create verifiable evidence before sharing digital work. It focuses on the exact file version being certified, uses cryptographic fingerprinting, provides a downloadable certificate, and supports independent verification. It also avoids presenting the service as copyright registration: copyright exists independently, while StampR creates evidence around authorship declaration, file identity, and time.

How would you describe the primary audience of your product?

StampR.eu's answer

StampR is primarily for creators, freelancers, professionals and organizations that need to document a digital work before sharing it externally. Typical use cases include music, photography, design, written works, source code, research, concepts, drafts and other digital files where proving the existence of a specific version at a particular time can be useful.

What's the story behind your product?

StampR.eu's answer

StampR was built around a practical problem: digital work is often shared with clients, collaborators, publishers or platforms before there is a clear, independently verifiable record of the exact version that existed beforehand. StampR turns that step into a straightforward workflow by combining file fingerprinting, an authorship declaration, timestamp evidence and a certificate that can later be verified.
