PAPPADIA® Music Digital Fingerprint (MDF) v2.3 — A Protocol for Mathematically Verifiable Musical Copyright

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ENGLISH━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PAPPADIA® Music Digital Fingerprint (MDF) v2.3 is a deterministicprotocol for mathematically verifiable musical copyright registration,based on the PAPPADIA® Theorem (© Umberto Junior Pappadia, 2025;DOI: 10.5281/ZENODO.17130066): d_m(1/p, 10) = floor( 10 × (10^(m-1) mod p) / p ) Each melody is encoded as a digit sequence embedded in the decimalexpansion of 1/p, certified via SHA-256 deposited on Zenodo with animmutable DOI. Version 2.3 introduces Compound Encoding (chromatic +interval concatenation, 2N-1 digits for an N-note melody) and minimumnote requirements for legal admissibility: 4-note compound → 7 digits → E[occ] ≈ 0.001 (Acceptable) 6-note compound → 11 digits → E[occ] < 10⁻⁶ (Bulletproof) The derivation algorithm (PAPPADIA® Framework, Tier 3) remains aprotected trade secret under Art. 98-99 D.Lgs. 30/2005 and is NOTpublished here. Tier 1 verification uses only Python built-in pow(). This record includes: · Bilingual scientific paper (EN/IT) on the MDF protocol (v1.3) · Tier 1 public library (AGPL-3.0): verification, encoding, search · Standalone verifier for court/CTU use (zero dependencies, updated) · Certified public demo registry (7 entries, public-domain works only) · DATABASE_LICENSE.txt (dual: CC BY-NC-SA 4.0 / Commercial) · SHA-256 integrity certificate (corrected edition) · README_ZENODO.md Properties: deterministic, court-admissible, audio-manipulation-invariant,pre-recording (certifies the musical idea before any audio recording),compliant with EU AI Act 2024/1689 Art. 50 (machine-readable watermarkingfor AI-generated audio), and with the opt-out mechanism of Art. 4(3)Dir.

La versione 2.3 introduce la CodificaComposta (concatenazione di cifre cromatiche e a intervalli, 2N-1 cifreper una melodia di N note) e requisiti minimi di lunghezza melodica perl'ammissibilità legale: 4 note compound → 7 cifre → E[occ] ≈ 0.001 (Accettabile) 6 note compound → 11 cifre → E[occ] < 10⁻⁶ (Inoppugnabile) L'algoritmo di derivazione (PAPPADIA® Framework, Tier 3) rimane segretocommerciale protetto dagli artt. 98-99 D.Lgs. 30/2005 e NON è pubblicato.La verifica Tier 1 utilizza esclusivamente la funzione built-in pow() diPython 3, senza dipendenze esterne. Questo record include: · Paper scientifico bilingue (EN/IT) sul protocollo MDF (v1.3) · Libreria pubblica Tier 1 (AGPL-3.0): verifica, codifica, ricerca · Verificatore autonomo per tribunale/CTU (zero dipendenze, aggiornato) · Registro demo pubblico certificato (7 voci, solo opere di pubblico dominio) · DATABASE_LICENSE.txt (doppia licenza: CC BY-NC-SA 4.0 / Commerciale) · Certificato di integrità SHA-256 (edizione corretta) · README_ZENODO.md Proprietà: deterministico, ammissibile in tribunale, invariante allemanipolazioni audio, pre-registrazione (certifica l'idea musicale primadi qualsiasi registrazione audio), conforme all'AI Act UE 2024/1689Art. 50 (watermarking machine-readable per audio generato da IA) e almeccanismo di opt-out dell'Art. 4(3) Dir.
