If someone creates fake versions of your content, certified original proves authenticity. Temporal proof shows your version pre-dates manipulated copies.
🔗 Public Verification for Stakeholders
Media, clients, partners can instantly verify your content authenticity. Builds trust without requiring them to contact you or DAPI directly.
🔐 Technical Foundation (Both Pathways)
Why SHA-256 Hashing Is Legally Useful
The Technical Foundation of Digital Evidence
A SHA-256 hash is a unique digital fingerprint of a file. If a single byte changes—even one pixel in an image or one character in a document—the fingerprint changes completely. This mathematical property makes hashing one of the strongest practical tools to support integrity verification and to demonstrate that a file presented later is identical to the file certified at a specific point in time.
How Hash Verification Works
- At certification time: DAPI generates SHA-256 hashes of your original files and includes them in the certificate with a qualified timestamp.
- When you need to prove authenticity: You present both the certificate (with hashes) and your original files to a third party (court, platform, expert).
- Independent verification: The third party recalculates hashes of your files and compares them to the certified hashes. A match proves the files are authentic and unaltered since certification.
Timestamp Verification
Every DAPI certificate includes an eIDAS-qualified timestamp that proves when the certification occurred. This timestamp can be independently verified using RFC 3161 validation tools, ensuring transparency and preventing any possibility of backdating.
🔍 Verify Your Timestamp Certificate
DAPI uses qualified timestamp services compliant with eIDAS Regulation (EU) No 910/2014. You can independently verify the authenticity and validity of your timestamp certificate using our public verification tool.

❓ Frequently Asked Questions
Is DAPI certification legally admissible in court?
DAPI certification uses forensic standards (ISO/IEC 27037) and eIDAS-qualified timestamps recognized across EU jurisdictions and admissible in courts across the European Union, the United States, the United Kingdom, Canada, Australia, and other jurisdictions with equivalent legal frameworks. However, final admissibility depends on your specific case, jurisdiction, and how the evidence is presented. Consult with legal counsel to ensure proper introduction of evidence.
Which package do I need for platform takedowns?
DAPI-IDS (Private Identity Baseline Certification) is sufficient for impersonation and fake profile reports. DAPI-PUB (Public Certification of Identity and Content) strengthens claims by providing public verification listing that platforms can check instantly without requiring you to submit files.
Which package do I need for content copyright protection?
DAPI-PUB (Public Certification of Identity and Content) required. DAPI-IDS (Private Identity Baseline Certification) certifies your identity baseline but does not link specific content to you. DAPI-PUB (Public Certification of Identity and Content) creates per-content certificates with public verification, timestamps, and DAPI badges proving your authorship.
Can I upgrade from Private to Publications later?
Yes. Your DAPI-IDS (Private Identity Baseline Certification) certification remains valid. You can add Publications certification at any time to create public verification listings for specific content. Your identity baseline does not need recertification.
What if I lose my original files?
The DAPI-IDS (Private Identity Baseline Certification) certificate contains only cryptographic hashes—not the actual files. If you lose your original files, the certificate alone cannot prove authenticity (because third parties need to verify that your current files match the certified hashes). This is why we strongly emphasize preserving your original certified files in multiple secure locations.
Are my publications publicly searchable?
With DAPI-PUB (Public Certification of Identity and Content): Yes, each certified publication gets a dedicated verification listing at verify-dapi.com/[your-identifier]/ accessible via direct link, QR code, or DAPI badge. However, these listings are not indexed by search engines and only contain information you explicitly certified—no additional personal data is exposed. DAPI-IDS (Private Identity Baseline Certification): No public listings whatsoever.
How long does DAPI certification remain valid?
The cryptographic hashes and timestamp remain technically valid indefinitely. However, practical validity depends on whether your identity materials remain current. If your identity document expires or your appearance changes significantly, consider updating your certification. For legal purposes, temporal proof is strongest when the certification date is reasonably close to the dispute timeframe.
Can platforms reject DAPI certification?
Platforms have discretion in their moderation decisions. However, cryptographically certified evidence significantly strengthens your position by removing ambiguity about identity and authenticity. In our experience, platforms respond more quickly and favorably when provided with structured technical proof rather than unverified claims. DAPI-PUB (Public Certification of Identity and Content) further accelerates response by providing instant third-party verification.
⚠️ Important Legal Disclaimers
- DAPI provides technical evidence, not legal guarantees. The certification creates a technically sound proof package with forensic methodology and qualified timestamps. However, it does not guarantee specific outcomes in legal proceedings, platform moderation, or law enforcement investigations.
- Legal counsel is recommended for complex disputes. While many users successfully use DAPI certificates independently for platform reports and informal disputes, complex legal matters require professional guidance.
- DAPI-PUB (Public Certification of Identity and Content) creates public listings. If you choose Publications certification, your certified content will have public verification listings on verify-dapi.com. Only certify content you are comfortable making publicly verifiable.
- You must preserve your original files. The DAPI-IDS (Private Identity Baseline Certification) certificate contains only cryptographic hashes—not the files themselves. To use the certification in legal or platform contexts, you must present both the certificate and your original files so third parties can verify that the hashes match.
- Outcomes depend on jurisdiction and circumstances. DAPI uses internationally recognized standards (RFC 3161, SHA-256, ISO/IEC 27037), but legal systems vary. eIDAS-qualified timestamps have automatic legal recognition across EU member states, but international recognition depends on local laws.
- DAPI-IDS (Private Identity Baseline Certification) is private by design—zero public exposure. Unlike DAPI-PUB (Public Certification of Identity and Content), DAPI-IDS (Private Identity Baseline Certification) does not create public profiles, publish data online, or maintain searchable databases. Your certified materials remain completely private—only you receive the evidence package.
- Timestamp verification is independently available. All DAPI timestamps can be independently verified using public RFC 3161 validation tools at tsr-viewer.certifiedpressreleases.com. This independent verification strengthens evidentiary value.
