01 / UNDERSTANDING DAPI
What it is, what it isn’t, and why it matters more than ever today
The Problem DAPI Solves
In 2025, deepfake videos increased by 900%.
And new AI tools in 2026 can clone your face, voice, and identity in minutes.
When abuse occurs, the most critical challenge is proving
who you actually were before the fake content appeared.
DAPI (Digital Authentication for Personal Identity)
is a controlled certification process that creates
verifiable forensic evidence of your authentic identity at
a specific point in time, with legal value and complete privacy flexibility.
Two DAPI Certification Pathways
DAPI-IDS (Private Identity Baseline Certification)
Establish your verified identity baseline with a completely private forensic evidence package.
No public exposure—only you receive the certificate.
- ✓ Certified identity baseline
- ✓ SHA-256 cryptographic hashes
- ✓ eIDAS qualified timestamp
- ✓ Forensic documentation
- ✓ Completely private
Ideal for: Preventive protection, deepfake defense, impersonation disputes
DAPI-PUB (Public Certification of Identity and Content)
Identity baseline plus public certification of your online content.
Each publication gets a verifiable listing on verify-dapi.com.
- ✓ Everything in DAPI-IDS (Private Identity Baseline Certification)
- ✓ Public verification listings
- ✓ Certificate per publication
- ✓ DAPI protection badge
- ✓ QR code for verification
Ideal for: Content creators, public figures, copyright protection, anti-manipulation
See Detailed Comparison Between PathwaysWhat DAPI Is
- Forensic certification with dual modes
Generates cryptographic evidence of your identity (always private) with optional public certification of your online content
- Legally-oriented documentation
Designed for takedown requests, legal proceedings, and law enforcement collaboration
- Expert-supervised process
Manual handling by forensic expert with 24 years of experience, no automation, no AI processing
- Zero-database architecture
Files deleted within 48 hours; only cryptographic hashes retained (non-reversible)
- eIDAS-compliant timestamps
Qualified time proof with legal value throughout the EU and internationally recognized standards
What DAPI Is Not
- Not a biometric database
We don’t store, catalog, or search your biometric data
- Does not expose private identity data
Your identity baseline remains always private. Only certified publications (if you choose this option) have public listings
- Not an automated platform
No algorithms, no AI validation, no mass processing—every certification is personally supervised
- Not a KYC service
DAPI creates forensic evidence for personal legal protection, not corporate identity verification
- Not a content removal guarantee
We provide evidence to strengthen your position; we cannot control platform decisions
International Legal Recognition with FEDIS
DAPI certificates (both pathways) include FEDIS (Forensic Evidence Declaration & Integrity Statement)—an
expert declaration methodology that extends legal recognition beyond the European Union.
How it works: The complete DAPI certificate package (with all cryptographic hashes,
timestamps, and technical documentation) is digitally signed with a qualified electronic signature by the
forensic expert. This expert declaration transforms the evidence package into a sworn technical statement with enhanced admissibility.
✓ Legal jurisdictions where FEDIS-certified evidence is admissible:
- European Union (automatic recognition via eIDAS + technical expertise)
- United States (Federal Rules of Evidence 702, 901, 902)
- United Kingdom (Expert Evidence under Civil Procedure Rules)
- Canada (Expert Opinion Evidence)
- Australia (Evidence Act 1995, Expert Opinion)
- Other common law jurisdictions with equivalent expert witness frameworks

02 / TYPES OF EVIDENCE
Priority, integrity, and identity consistency
Why DAPI Matters More Than Ever Today
When deepfakes, voice cloning, or impersonation occur,
platforms and authorities ask the same question:
“How do we know that this is the real you and that is the fake?”
Without pre-existing certified evidence, proving authenticity becomes
nearly impossible. DAPI creates that proof before you need it.
Proof of Priority
Proves that your authentic identity materials existed
at a specific date and time—before fake content appeared.
✓ Available in both DAPI pathways
Proof of Integrity
Cryptographic hashes ensure that certified files
have not been altered since certification—any modification produces a completely different hash.
✓ Available in both DAPI pathways
Identity Consistency
Establishes a consistent baseline of your appearance,
voice, and identity documents for verification and comparison purposes.
✓ Available in both DAPI pathways
Content Authenticity Proof
Cryptographically links your verified identity to specific
content you’ve published online, with instant public verification.
✓ Only with DAPI-PUB (Public Certification of Identity and Content)
03 / WHAT YOU CERTIFY
The files that establish your biometric baseline and (optionally) your online content
What You Certify with DAPI
DAPI certification is based on identity-related files that establish your authentic biometric baseline.
With DAPI-PUB (Public Certification of Identity and Content) pathway, you can also certify your published online content.
Identity Baseline (Both Pathways)
Identity Document
Valid government-issued ID (passport, national ID card, driver’s license)
- High-quality PDF or JPG
- Clear and readable text and photo
- Current and not expired
- Private file—used only for certification
Face Photograph
Front-facing photo that establishes your authentic appearance
- Frontal pose, natural lighting
- No sunglasses or obstructions
- Neutral background preferred
- High resolution (min 1280x720px)
Voice Recording
Audio sample that certifies your authentic vocal characteristics
- 30-60 seconds duration
- Reading of provided standard text
- Clear audio quality (MP3/WAV)
- Quiet environment, no background noise
Verification Video
Brief video for advanced authentication (optional but strongly recommended)
- 10-15 seconds, MP4 format
- Looking at camera, face centered
- Slight side-to-side head movement (left/right)
- Provides strongest proof against deepfakes
Optional but Recommended
a SHA-256 cryptographic hash (fingerprint), which is then certified
with an eIDAS-compliant qualified timestamp. This creates legally admissible evidence
that cannot be forged or backdated.

Critical: You Must Preserve Your Original Files
The DAPI certificate contains ONLY cryptographic hashes (fingerprints)
of your files, not the files themselves. If you need to use the certificate
for legal purposes, you must present:
- The DAPI certificate (with hashes, timestamp, and digital signature)
- Your original files (document, photo, audio, video)
Third parties (courts, platforms, authorities) can then recalculate
the hashes of your files and verify they match the certified hashes, proving
the files are authentic and existed at the certification date.
Recommended preservation: Multiple backups (local + encrypted cloud),
offline storage (USB/external drive), never modify the original files.
06 / WHEN DAPI IS NEEDED
Real-world scenarios where forensic identity proof matters
When DAPI Is Useful
DAPI provides defensive evidence for a wide range of digital identity misuse scenarios, from everyday impersonation to sophisticated AI attacks, establishing the baseline for deepfake detection.
Once the deepfake exists, proving who is the real “you” becomes nearly impossible without pre-existing, preventive certification.
DAPI establishes your authentic baseline BEFORE abuse occurs, creating the only evidence that can distinguish the original from the fake with cryptographic certainty.

07 / HOW TO USE YOUR CERTIFICATE
Practical guide for legal and defensive use
How to Use Your DAPI Certificate
The DAPI certificate package is designed for immediate use in
defensive and legal contexts. Usage methods vary based on the pathway chosen.
Platform Reports and Takedowns
Use case: Fake profile, unauthorized image use, social media impersonation
With DAPI-IDS (Private Identity Baseline Certification):
- Submit standard platform abuse report (Instagram, Facebook, LinkedIn, etc.)
- Attach DAPI certificate PDF as supporting evidence
- Reference the certificate in text: “Certified proof of authentic identity attached (DAPI-[code])”
- If verification requested, provide original files + certificate for hash comparison
With DAPI Certified Publications:
- Follow the same steps as DAPI-IDS (Private Identity Baseline Certification)
- Additional advantage: Include link to your verify-dapi.com/[identifier]/ page in the report
- Platform can instantly verify your identity and authentic publications without further requests
- Further accelerates response times by eliminating need for document exchanges
Impact: Certified evidence typically accelerates platform response
from weeks to days. With Publications, instant verification can reduce times to hours.
Legal Proceedings and Criminal Complaints
Use case: Deepfake defamation, identity theft, fraud, revenge porn
How to use DAPI (Both Pathways):
- Provide DAPI certificate to your attorney
- Include in formal complaints to law enforcement (Postal Police, FBI IC3, etc.)
- Present as exhibit in civil or criminal proceedings
- Use for cease-and-desist letters to prove legitimate identity claim
Certified Publications Advantage:
If the case involves content you’ve published (e.g., manipulated videos, falsely attributed articles),
the public listing with timestamp provides immediate and verifiable proof of original authorship.
Legal value: eIDAS qualified timestamp and forensic methodology
provide evidentiary weight recognized by courts throughout the EU and many international jurisdictions including US, UK, Canada, and Australia.
GDPR and Privacy Enforcement
Use case: Unauthorized data processing, right to erasure, personality rights violations
How to use DAPI (Both Pathways):
- Submit GDPR complaint to platform/website (Art. 17 – Right to erasure)
- Include DAPI certificate proving you are the legitimate data subject
- If ignored, escalate to Data Protection Authority (e.g., ICO in UK, CNIL in France)
- Reference certificate as proof of legitimate interest and identity
Advantage: Eliminates platform’s ability to claim they cannot
verify your identity; certified proof removes this excuse.
Deepfake Detection and Comparison
Use case: Contested video/audio authenticity, forensic analysis needed
How to use DAPI (Both Pathways):
- Provide DAPI certificate + original files to forensic expert or law enforcement
- Certified baseline enables technical comparison with contested content
- Facial/voice analysis can identify synthetic artifacts vs. authentic characteristics
- Timestamp proves your authentic materials predate fake content
Technical advantage: Certified baseline significantly improves
accuracy of deepfake detection tools and expert analysis.
Copyright Protection and Content Anti-Manipulation
Publications Only
Use case: Content theft, plagiarism, unauthorized republication, video/article manipulation
How to use DAPI Certified Publications:
- Prevention: Display DAPI badge on videos, posts, articles as visual deterrent against theft
- Public Verification: Followers, clients, partners can scan QR code to instantly verify authenticity
- DMCA Takedown: Submit per-publication certificate with takedown, including link to verify-dapi.com listing
- Priority Proof: Public timestamp proves your content predates infringing copies
- Copyright Disputes: Public listing serves as immediate proof of original authorship
Practical Example:
A content creator finds their video reuploaded without permission. Instead of weeks of back-and-forth emails,
they send a DMCA report with the publication certificate and verify-dapi.com link. The platform
instantly verifies original authorship via QR code and removes the infringing copy within 24-48 hours.
Unique advantage: Visible badge on original content deters theft
before it happens. When it does happen, instant verification drastically accelerates resolution.
General Best Practices
- Store certificate + originals together:
Archive the DAPI certificate and original files in the same secure location for easy access - Act promptly:
Submit reports/complaints as soon as abuse is discovered; temporal proximity strengthens the case - Document everything:
Make certified forensic captures of fake content since screenshots are weak evidence with no effective legal value, save URLs, record dates, combine with DAPI proof for strongest position - With Publications: Maximize badge visibility:
Embed DAPI badge in videos (watermark), social posts (bio/description), articles (footer), online portfolio - With Publications: Promote verification:
Include phrase like “This content is DAPI-certified – scan QR code to verify” to educate your audience - Seek legal counsel:
DAPI provides technical evidence, but attorney guidance ensures optimal legal strategy - Multiple use allowed:
One certificate can support multiple actions; no need to recertify for each incident - Update if needed:
If identity document expires or appearance changes significantly, consider updated certification
08 / THE CORE PRINCIPLE OF DAPI
Proving who you were before, not who you are now
The Core Principle of DAPI
DAPI serves to prove what your real identity was before any abuse, cloning, or impersonation occurred.
This temporal distinction is fundamental. When abuse occurs, the problem is not proving who you are today, but proving that your authentic identity existed before fake, manipulated, or falsely attributed content appeared. The THREE CORE PRINCIPLES OF DAPI:
- Certain and verifiable temporal proof
DAPI creates temporal proof prior to abuse, based on cryptographic hashes and qualified timestamps, with legal value and independent verifiability. - Drastic reduction in legal time and costs
Having a certified baseline enables immediate action, avoiding lengthy preliminary disputes and significantly reducing time and costs of legal actions or takedown requests. - Reputation protection and prevention of erroneous evaluations
DAPI eliminates the ambiguity that often leads to wrong judgments by public opinion, media, or platforms, protecting the person’s reputation before damage becomes irreversible.
With DAPI-PUB : Proactive Public Protection
Beyond the defensive baseline, Certified Publications add a layer of proactive public protection:
the visible badge and instant verification deter content theft before it happens,
and when it does happen, drastically accelerate resolution by immediately showing who the original author is.
