Summary/Abstract: The report presents a model for declarative disclosure of authorship and time attestation of digital works using a qualified electronic time stamp. It is shown how the cryptographic fingerprint (SHA-256) enables unambiguous identification of a digital original without storing its content, while the RFC 3161 time stamp issued by a Qualified Trust Service Provider (QTSP), in accordance with eIDAS and ETSI EN 319 421/422, provides a verifiable moment of existence and integrity. The engineering implementation within the StampR platform is described: local hashing, a request to the TSA, receipt of the Time-Stamp Token (TST), and generation of a PDF certificate with public verification instructions. The approach is compared to traditional offline practices across dimensions such as accessibility, time-to-result, cost, cross-border applicability, and privacy. It is shown how the model reduces transaction costs for rights protection and accelerates the path from idea to market for authors, ICT teams, and SMEs. The legal framework and TST validation are also examined.
