Zusammenfassung Abstract Resumo

KI-Systeme konnen institutionell gestaltete Dokumente erzeugen, die offizielle Mitteilungen nahezu perfekt imitieren. Diese Fahigkeit fuhrt zu einer neuen Klasse von Betrugsrisiken: Dokumenten-Deepfakes, bei denen Authentizitat aus dem Erscheinungsbild statt aus uberprufbarer Herkunft abgeleitet wird. Dieser Bericht stellt ein Secure Origin Framework (SOF) fur KI-gestutzte institutionelle Dokumente vor, implementiert als WINDI DeepDOCFakes-Abteilung. Das Framework verankert jedes governierte Dokument an einem reproduzierbaren Provenienz-Record, einem kanonischen strukturellen Fingerabdruck und einem Verifizierungsprotokoll, das VALID / UNKNOWN / TAMPERED zuruckgibt. AI systems can generate institutionally styled documents that closely mimic official communications. This capability introduces a new class of fraud risk: document deepfakes, where authenticity is inferred from appearance rather than verifiable origin. This report introduces a Secure Origin Framework (SOF) for AI-assisted institutional documents, implemented as the WINDI DeepDOCFakes division. The framework anchors each governed document to a reproducible provenance record, a canonical structural fingerprint, and a verification protocol returning VALID / UNKNOWN / TAMPERED. A quantitative Deepfake Resilience Score (0–100) provides an audit-friendly language for comparing governance strength across institutional risk tiers. The result is a paradigm shift from "document looks authentic" to "document origin is verifiable." Sistemas de IA podem gerar documentos com estilo institucional que imitam de perto comunicacoes oficiais. Essa capacidade introduz uma nova classe de risco de fraude: deepfakes de documentos, onde a autenticidade e inferida da aparencia em vez da origem verificavel. Este relatorio introduz um Framework de Origem Segura (SOF) para documentos institucionais assistidos por IA, implementado como a divisao WINDI DeepDOCFakes.

1. Problemstellung 1. Problem Statement 1. Declaracao do Problema

1.1 Dokumenten-Deepfakes als aufkommende Bedrohung 1.1 Document Deepfakes as an Emerging Threat 1.1 Deepfakes de Documentos como Ameaca Emergente

Dokumenten-Deepfakes unterscheiden sich grundlegend von Video- oder Audio-Deepfakes: Sie nutzen das Vertrauen in institutionellen Ton, Layout, Symbole und Formatierung aus. Ein gefalschtes PDF kann uberzeugend sein, selbst wenn es nie in den Systemen der ausstellenden Institution existierte. Document deepfakes differ fundamentally from video or audio deepfakes: they exploit trust in institutional tone, layout, symbols, and formatting. A forged PDF can be convincing even if it never existed within the issuing institution's systems. This threat grows with three converging capabilities: high-fidelity text generation in institutional style, easy replication of visual identity, and weak provenance mechanisms in common PDF workflows. Deepfakes de documentos diferem fundamentalmente de deepfakes de video ou audio: eles exploram a confianca no tom institucional, layout, simbolos e formatacao. Um PDF falsificado pode ser convincente mesmo que nunca tenha existido nos sistemas da instituicao emissora.

Bedrohungsvektor — Dokumenten-Deepfake Threat Vector — Document Deepfake Vetor de Ameaca — Deepfake de Documento

Ein Angreifer verwendet ein KI-System, um ein PDF zu generieren, das den Ton, die Struktur, rechtliche Referenzen und Formatierung einer BaFin-Regulierungsmitteilung perfekt repliziert. Das Dokument ist durch visuelle Inspektion allein nicht von einer authentischen aufsichtlichen Mitteilung zu unterscheiden. Ohne eine Provenienz-Infrastruktur hat der Empfanger keinen Mechanismus, um die institutionelle Herkunft uber subjektive Beurteilung hinaus zu verifizieren. An adversary uses an AI system to generate a PDF that perfectly replicates the tone, structure, legal references, and formatting of a BaFin regulatory communication. The document is indistinguishable from an authentic aufsichtliche Mitteilung by visual inspection alone. Without a provenance infrastructure, the recipient has no mechanism to verify institutional origin beyond subjective judgment of "whether it looks right." Um adversario usa um sistema de IA para gerar um PDF que replica perfeitamente o tom, estrutura, referencias legais e formatacao de uma comunicacao regulatoria da BaFin. O documento e indistinguivel de uma aufsichtliche Mitteilung autentica apenas por inspecao visual. Sem uma infraestrutura de proveniencia, o destinatario nao tem mecanismo para verificar a origem institucional alem do julgamento subjetivo.

1.2 Warum traditionelle Kontrollen unzureichend sind 1.2 Why Traditional Controls Are Insufficient 1.2 Por que Controles Tradicionais Sao Insuficientes

Wasserzeichen, Briefkopfe und "professionelle Formatierung" sind kopierbar. Selbst Unterschriften konnen simuliert werden. Ohne eine kryptografisch und registrierungsverankerte Provenienzschicht bleibt die Dokumentenauthentizitat eine Frage der subjektiven Interpretation. Die Schlusselerkenntnis ist tauschend einfach: Visuelle Ahnlichkeit ist keine Authentizitat. Watermarks, letterheads, and "professional formatting" are copyable. Even signatures can be simulated. Without a cryptographic and registry-anchored provenance layer, document authenticity remains a matter of subjective interpretation. The key insight is deceptively simple: visual similarity is not authenticity. Marcas d'agua, cabecalhos e "formatacao profissional" sao copiaveis. Ate assinaturas podem ser simuladas. Sem uma camada de proveniencia criptografica e ancorada em registro, a autenticidade do documento permanece uma questao de interpretacao subjetiva. Similaridade visual nao e autenticidade.

2. Forschungsbeitrag 2. Research Contribution 2. Contribuicao da Pesquisa

Dieser Bericht tragt ein operatives Framework fur die Authentizitat institutioneller Dokumente in KI-gestutzten Generierungskontexten bei. Der Beitrag ist keine visuelle Anti-Betrugs-Technik; es ist eine systemweite Provenienz-Infrastruktur fur institutionelle Dokumentation. This report contributes an operational framework for institutional document authenticity in AI-assisted generation contexts. The contribution is not a visual anti-fraud technique; it is a systems-level provenance infrastructure for institutional documentation. Este relatorio contribui com um framework operacional para autenticidade de documentos institucionais em contextos de geracao assistida por IA. A contribuicao nao e uma tecnica visual anti-fraude; e uma infraestrutura de proveniencia em nivel de sistema para documentacao institucional.

3. Bedrohungsmodell 3. Threat Model 3. Modelo de Ameaca

3.1 Angreiferfahigkeiten 3.1 Attacker Capabilities 3.1 Capacidades do Atacante

Ein Dokumenten-Deepfake-Angreifer kann institutionell gestalteten Text mit Tonimitation generieren, Layouts und Vorlagen replizieren, plausible institutionelle Attribute einfugen (Adressen, Abteilungen, Slogans) und uberzeugende PDFs mit kopierten Logos erstellen, wenn die Identitat unkontrolliert ist. A document deepfake attacker can generate institutionally styled text with tone mimicry, replicate layouts and templates, insert plausible institutional attributes (addresses, departments, slogans), and produce convincing PDFs with copied logos when identity is uncontrolled. Um atacante de deepfake de documentos pode gerar texto com estilo institucional com imitacao de tom, replicar layouts e modelos, inserir atributos institucionais plausiveis (enderecos, departamentos, slogans) e produzir PDFs convincentes com logos copiados quando a identidade nao e controlada.

3.2 Angreiferbeschrankungen (in Secure Origin Systemen) 3.2 Attacker Limitations (in Secure Origin Systems) 3.2 Limitacoes do Atacante (em Sistemas de Origem Segura)

Innerhalb eines WINDI-governierten Systems kann der Angreifer nicht: interne Provenienz-Records im autoritativen Register reproduzieren, kanonische strukturelle Fingerabdrucke rekonstruieren, die mit der aufgezeichneten Provenienz ubereinstimmen, oder verifizierte Registrierungsverknupfungen falschen ohne Zugang zur Ausstellungsinfrastruktur. Within a WINDI-governed system, the attacker cannot: reproduce internal provenance records in the authoritative registry, reconstruct canonical structural fingerprints consistent with recorded provenance, or fake verified registry linkage without access to the issuance infrastructure. The structural hash includes governance context, server identity, and timestamps that are invisible in the document itself. Dentro de um sistema governado pelo WINDI, o atacante nao pode: reproduzir registros de proveniencia internos no registro autoritativo, reconstruir impressoes digitais estruturais canonicas consistentes com a proveniencia registrada, ou falsificar vinculacao de registro verificada sem acesso a infraestrutura de emissao.

3.3 Sicherheitsziel 3.3 Security Goal 3.3 Objetivo de Seguranca

Sicherstellen, dass Authentizitatsanspruche durch uberprufbare Herkunft gestutzt werden, nicht durch Erscheinungsbild. Jede Manipulation oder systemexterne Generierung sollte als UNKNOWN oder TAMPERED durch deterministische Verifizierung erkennbar sein. Ensure authenticity claims are supported by verifiable origin, not appearance. Any tampering or off-system generation should be detectable as UNKNOWN or TAMPERED through deterministic verification. Garantir que reivindicacoes de autenticidade sejam apoiadas por origem verificavel, nao por aparencia. Qualquer adulteracao ou geracao fora do sistema deve ser detectavel como UNKNOWN ou TAMPERED atraves de verificacao deterministica.

4.2 Struktureller Hash 4.2 Structural Hash 4.2 Hash Estrutural

Ein kanonischer struktureller Hash wird uber die Governance-Entscheidungspayload berechnet: Governance-Level, Policy-Version, Konfigurations-Hash, ISP-Profil, Organisation, regulatorische Metadaten und Identitats-Governance-Status. Der Hash verwendet einen versionierten Kanonisierungswrapper (_canon_version: 1.0) mit deterministischer JSON-Serialisierung. A canonical structural hash is computed over the governance decision payload: governance level, policy version, configuration hash, ISP profile, organisation, regulatory metadata, and identity governance status. The hash uses a versioned canonicalisation wrapper (_canon_version: 1.0) with deterministic JSON serialisation (sorted keys, no whitespace variation). If any governance parameter changes, the fingerprint changes — creating a structural identity that deepfakes cannot replicate because it depends on system-internal state. Um hash estrutural canonico e calculado sobre a carga de decisao de governanca: nivel de governanca, versao da politica, hash de configuracao, perfil ISP, organizacao, metadados regulatorios e status de governanca de identidade.

4.3 Provenienz-Record 4.3 Provenance Record 4.3 Registro de Proveniencia

Jedes governierte Dokument erhalt einen Provenienz-Record — eine "digitale Geburtsurkunde" — der das Dokument mit der geltenden Governance-Policy-Linie, Identitats-Governance-Beschrankungen (lizenziert vs. model_only), Metadaten-Vollstandigkeit, Zeitstempeln, Versiegelungszustand und der kryptografischen Beweiskette verknupft. Each governed document receives a provenance record — a "digital birth certificate" — that links the document to the governance policy lineage in effect, identity governance constraints (licensed vs. model_only), metadata completeness, timestamps, sealing state, and the cryptographic proof chain. The record includes system identity (WINDI, version, jurisdiction: DE, Strato infrastructure), ensuring that provenance is bound to a specific installation and jurisdiction. Cada documento governado recebe um registro de proveniencia — uma "certidao de nascimento digital" — que vincula o documento a linhagem da politica de governanca em vigor, restricoes de governanca de identidade (licenciado vs. model_only), completude de metadados, carimbos de data/hora, estado de selagem e cadeia de prova criptografica.

4.4 Verifizierungsprotokoll 4.4 Verification Protocol 4.4 Protocolo de Verificacao

Die Verifizierung gibt eines von drei deterministischen Ergebnissen zuruck: Verification returns one of three deterministic outcomes: A verificacao retorna um de tres resultados deterministicos:

Status Meaning Trigger Condition
VALID Record exists and structural fingerprint matches Structural hash recomputation equals stored hash
UNKNOWN No authoritative record exists Submission ID not found in provenance registry
TAMPERED Record exists but fingerprint mismatch detected Recomputed hash differs from stored hash

Table 2 — Verification protocol outcomes: the document equivalent of HTTPS certificate validation

Dies ist das Aquivalent eines Authentizitats-Handshakes: nicht "sieht richtig aus", sondern "nachweislich ausgestellt". This is the equivalent of an authenticity handshake: not "looks right," but "provably issued." Este e o equivalente de um handshake de autenticidade: nao "parece certo", mas "comprovadamente emitido".

5. Deepfake-Resilienz-Score 5. Deepfake Resilience Score 5. Pontuacao de Resiliencia a Deepfake

Ein Score zwischen 0 und 100 kommuniziert die Governance-Starke in Audit-Sprache. Der Score wird aus aktiven Sicherheitsfunktionen berechnet, einschliesslich Provenienzanforderungen, Registrierungsverankerung, strukturellem Hashing-Modus, eingebetteten Metadaten, Manipulationsnachweis, Identitats-Governance-Status und Jurisdiktionsbindung. A score between 0 and 100 communicates governance strength in audit language. The score is computed from active security features including provenance requirements, registry anchoring, structural hashing mode, embedded metadata, tamper evidence, identity governance status, and jurisdiction binding. Uma pontuacao entre 0 e 100 comunica a forca da governanca em linguagem de auditoria. A pontuacao e calculada a partir de recursos de seguranca ativos, incluindo requisitos de proveniencia, ancoragem de registro, modo de hash estrutural, metadados incorporados, evidencia de adulteracao, status de governanca de identidade e vinculacao de jurisdicao.

7. Bewertung 7. Evaluation 7. Avaliacao

7.1 Empirische Validierung 7.1 Empirical Validation 7.1 Validacao Empirica

Das Framework wurde durch 15 automatisierte Tests validiert, die am 02. Februar 2026 in der Produktion ausgefuhrt wurden. Diese deckten Reproduzierbarkeit (gleiche Payload erzeugt gleichen strukturellen Hash), Manipulationserkennung (Payload-Modifikation lost TAMPERED aus), Abwesenheitserkennung (unbekannte Submission-IDs geben UNKNOWN zuruck), Governance-Tier-Ordnung (HIGH > MEDIUM > LOW Resilienz-Scores), PDF-Metadaten-Generierung und Registry-Integritatsuberprufung ab. The framework was validated through 15 automated tests executed in production on 02 February 2026, covering reproducibility (same payload produces same structural hash), tamper detection (payload modification triggers TAMPERED), absence detection (unknown submission IDs return UNKNOWN), governance tier ordering (HIGH > MEDIUM > LOW resilience scores), PDF metadata generation, and registry integrity verification. O framework foi validado atraves de 15 testes automatizados executados em producao em 02 de fevereiro de 2026, cobrindo reprodutibilidade (mesma carga produz mesmo hash estrutural), deteccao de adulteracao (modificacao de carga aciona TAMPERED), deteccao de ausencia (IDs de submissao desconhecidos retornam UNKNOWN), ordenacao de niveis de governanca (pontuacoes de resiliencia HIGH > MEDIUM > LOW), geracao de metadados PDF e verificacao de integridade do registro.

15/15 tests passed. DeepDOCFakes module ready for production.

Self-test output from deploy_deepdocfakes.sh on Strato DE server (87.106.29.233). Tests executed against all three governance levels with HIGH (BaFin, 100/100), MEDIUM (Bundesregierung, 60/100), and LOW (TUV, 30/100) configurations. Registry integrity check: HEALTHY.

7.2 Praktische Kriterien 7.2 Practical Criteria 7.2 Criterios Praticos

Das Framework erfullt vier praktische Anforderungen: Verifizierbarkeit (unabhangige Prufung liefert deterministische Ergebnisse), Ruckverfolgbarkeit (Record verknupft mit Governance-Zustand bei Ausstellung), Manipulationsnachweis (Modifikationen sind durch Hash-Abweichung erkennbar) und Pruffahigkeit (Scores und Verifizierungsergebnisse sind fur nicht-technische Prufer und Regulatoren erklarbar). The framework satisfies four practical requirements: verifiability (independent check returns deterministic results), traceability (record links to governance state at issuance), tamper evidence (modifications are detectable through hash mismatch), and auditability (scores and verification outcomes are explainable to non-technical auditors and regulators). O framework satisfaz quatro requisitos praticos: verificabilidade (verificacao independente retorna resultados deterministicos), rastreabilidade (registro vinculado ao estado de governanca na emissao), evidencia de adulteracao (modificacoes sao detectaveis atraves de incompatibilidade de hash) e auditabilidade (pontuacoes e resultados de verificacao sao explicaveis para auditores e reguladores nao-tecnicos).

8. Regulatorische Ausrichtung 8. Regulatory Alignment 8. Alinhamento Regulatorio

EU AI Act — Article 12: Record-Keeping

Provenienz-Records bieten eine vollstandige Audit-Trail von Dokumentengenerierungsentscheidungen, einschliesslich Governance-Level, Policy-Version, Identitats-Governance-Status und kryptografischem Nachweis. Jeder Record wird mit atomaren Schreibvorgangen persistiert und fur effizienten Abruf indexiert. Provenance records provide a complete audit trail of document generation decisions, including governance level, policy version, identity governance status, and cryptographic proof. Each record is persisted with atomic writes and indexed for efficient retrieval. Registros de proveniencia fornecem uma trilha de auditoria completa das decisoes de geracao de documentos, incluindo nivel de governanca, versao da politica, status de governanca de identidade e prova criptografica.

EU AI Act — Article 14: Human Oversight

Das Vier-Augen-Prinzip in HIGH-Governance erfordert Dual-Control-Verifizierung vor der Dokumentenversiegelung. Das Framework erzwingt dies als Voraussetzung fur forensische Provenienz und stellt sicher, dass menschliche Aufsicht strukturell eingebettet ist, anstatt prozedural optional zu sein. The four-eyes principle in HIGH governance requires dual-control verification before document sealing. The framework enforces this as a prerequisite for forensic-grade provenance, ensuring human oversight is structurally embedded rather than procedurally optional. O principio de quatro olhos na governanca HIGH requer verificacao de controle duplo antes da selagem do documento. O framework impoe isso como pre-requisito para proveniencia de grau forense.

EU AI Act — Article 50: Transparency Obligations

Das Verifizierungsprotokoll erweitert die Transparenz von "Ist dies KI-generiert?" zu "Ist dies institutionell autorisiert?" Die Identitats-Governance-Integration (Abschnitt 10) stellt sicher, dass die Nutzung institutioneller Identitat explizit kontrolliert, offengelegt und durch die Provenienzkette verifizierbar ist. The verification protocol extends transparency from "is this AI-generated?" to "is this institutionally authorised?" The identity governance integration (Section 10) ensures that institutional identity usage is explicitly controlled, disclosed, and verifiable through the provenance chain. O protocolo de verificacao estende a transparencia de "isso e gerado por IA?" para "isso e institucionalmente autorizado?" A integracao de governanca de identidade (Secao 10) garante que o uso de identidade institucional seja explicitamente controlado, divulgado e verificavel atraves da cadeia de proveniencia.

Das Framework ist auch auf die Anforderungen der BaFin KI-Orientierungshilfe (18. Dezember 2025) fur Lifecycle-Governance und Risikodokumentation bei KI-gestutzten Finanzdienstleistungen ausgerichtet. The framework also aligns with BaFin's KI-Orientierungshilfe (18 December 2025) requirements for lifecycle governance and risk documentation in AI-assisted financial services. O framework tambem se alinha com os requisitos do KI-Orientierungshilfe da BaFin (18 de dezembro de 2025) para governanca de ciclo de vida e documentacao de risco em servicos financeiros assistidos por IA.

9. Einschrankungen und offene Fragen 9. Limitations and Open Questions 9. Limitacoes e Questoes Abertas

Provenienz-Frameworks erfordern eine autoritative Wahrheitsquelle, was bedeutet, dass die Registrierungs-Governance zu einer kritischen Abhangigkeit wird. Interoperable Verifizierung uber Organisationen hinweg benotigt Standardisierung uber das WINDI-SOF-Protokoll hinaus. Visuelle Identitatskontrollen (behandelt in Abschnitt 10) bleiben notwendig, sind aber allein unzureichend. Offline-Verifizierung und langfristige Archivierungsformate erfordern sorgfaltiges Design fur Dokumentenlebenszyklen, die uber die Betriebszeit des ausstellenden Systems hinausgehen. Provenance frameworks require an authoritative source of truth, meaning registry governance becomes a critical dependency. Interoperable verification across organisations needs standardisation beyond the WINDI-SOF protocol. Visual identity controls (addressed in Section 10) remain necessary but are insufficient alone. Offline verification and long-term archival formats require careful design for document lifecycles extending beyond the issuing system's operational period. Frameworks de proveniencia requerem uma fonte autoritativa de verdade, significando que a governanca do registro se torna uma dependencia critica. A verificacao interoperavel entre organizacoes precisa de padronizacao alem do protocolo WINDI-SOF. Controles de identidade visual (abordados na Secao 10) permanecem necessarios, mas sao insuficientes sozinhos. Verificacao offline e formatos de arquivamento de longo prazo requerem design cuidadoso para ciclos de vida de documentos que se estendem alem do periodo operacional do sistema emissor.

10. Zukunftige Arbeit 10. Future Work 10. Trabalho Futuro

Vier Richtungen sind fur das Secure Origin Framework geplant: ein externes Verifizierungs-Endpoint ("WINDI Verify") fur Prufer und Regulatoren, Cross-Validierungs-Attestierungen durch den Witness Dragon (Gemini) Mechanismus, SDMX-ausgerichteter Provenienz-Export fur regulatorische Berichtskontexte und ein standardisiertes Provenienz-Schema fur institutionelle Dokumentenokosysteme, das organisationsubergreifende Verifizierung ermoglichen konnte. Four directions are planned for the Secure Origin Framework: an external-facing verification endpoint ("WINDI Verify") for auditors and regulators, cross-validation attestations through the Witness Dragon (Gemini) mechanism, SDMX-aligned provenance export for regulatory reporting contexts, and a standardised provenance schema for institutional document ecosystems that could enable cross-organisational verification. Quatro direcoes estao planejadas para o Framework de Origem Segura: um endpoint de verificacao voltado para o exterior ("WINDI Verify") para auditores e reguladores, atestacoes de validacao cruzada atraves do mecanismo Witness Dragon (Gemini), exportacao de proveniencia alinhada ao SDMX para contextos de relatorios regulatorios, e um esquema de proveniencia padronizado para ecossistemas de documentos institucionais que poderia permitir verificacao entre organizacoes.

Fazit Conclusion Conclusao

Dokumenten-Deepfakes verschieben das institutionelle Vertrauen von Evidenz zu Asthetik. Das Secure Origin Framework antwortet, indem es Authentizitat in verifizierbarer Provenienz neu verankert: kanonisches strukturelles Hashing, registrierungsverankerte Provenienz-Records und deterministische Verifizierungsergebnisse. DeepDOCFakes bietet eine skalierbare und prufungsfreundliche Architektur fur KI-gestutzte institutionelle Inhalte in regulierten Umgebungen. Document deepfakes shift institutional trust from evidence to aesthetics. The Secure Origin Framework responds by re-grounding authenticity in verifiable provenance: canonical structural hashing, registry-anchored provenance records, and deterministic verification outcomes. DeepDOCFakes provides a scalable and audit-friendly architecture for AI-assisted institutional content in regulated environments. Deepfakes de documentos deslocam a confianca institucional da evidencia para a estetica. O Framework de Origem Segura responde re-ancorando a autenticidade em proveniencia verificavel: hash estrutural canonico, registros de proveniencia ancorados em registro e resultados de verificacao deterministicos. O DeepDOCFakes fornece uma arquitetura escalavel e amigavel para auditoria para conteudo institucional assistido por IA em ambientes regulados.

Dieses Framework verbindet die WINDI-Governance-Architektur von Ende zu Ende: Das ISP-Register (TR-006) definiert institutionelle Profile, die Identity Governance Layer (Abschnitt 10) kontrolliert die institutionelle Identitatsnutzung, und das Secure Origin Framework (TR-007) garantiert, dass governierte Dokumente uberprufbaren Nachweis ihrer institutionellen Herkunft tragen. Zusammen etablieren sie eine vollstandige Provenienzkette von der institutionellen Identitat bis zur Dokumentenverifizierung. This framework connects the WINDI governance architecture from end to end: the ISP Registry (TR-006) defines institutional profiles, the Identity Governance Layer (Section 10) controls institutional identity usage, and the Secure Origin Framework (TR-007) guarantees that governed documents carry verifiable proof of their institutional origin. Together, they establish a complete provenance chain from institutional identity to document verification. Este framework conecta a arquitetura de governanca do WINDI de ponta a ponta: o Registro ISP (TR-006) define perfis institucionais, a Camada de Governanca de Identidade (Secao 10) controla o uso de identidade institucional, e o Framework de Origem Segura (TR-007) garante que documentos governados carreguem prova verificavel de sua origem institucional. Juntos, estabelecem uma cadeia de proveniencia completa da identidade institucional ate a verificacao de documentos.

"Wir schutzen nicht das Erscheinungsbild des Dokuments.
Wir schutzen die institutionelle Existenz davon."
"We don't protect the appearance of the document.
We protect the institutional existence of it."
"Nao protegemos a aparencia do documento.
Protegemos a existencia institucional dele."
