What it is, what it is not, and why it matters more today than ever
New AI tools can clone your face, your voice, and your identity in minutes. When abuse occurs, the most critical challenge is proving who you really were before the fake content appeared.
DAPI (Digital Authentication for Personal Identity) is a controlled certification process that creates a verified, temporally documented identity baseline, designed to support legal and evidentiary use, with the flexibility to choose your level of privacy.
Establish your verified identity baseline with a completely private forensic evidence package. No public exposure: only you receive the certificate.
Ideal for: preventive protection, deepfake defense, impersonation disputes
Identity baseline plus public certification of your online content. Every publication gets a verifiable listing.
Ideal for: content creators, public figures, copyright protection, anti-manipulation
DAPI is also the identity verification path required before activating an EVIDE account. EVIDE is an evidentiary accountability platform designed to preserve, in structured and verifiable form, Declarations relating to decisions, declared authority, context, and declared responsibility.
DAPI verifies the identity of the person. It does not determine or validate their professional role, authority, or the correctness of what they declare. EVIDE preserves the declared context and evidentiary elements associated with the Declaration; it does not autonomously determine the substantive truth, correctness, or legitimacy of the decision.
Person → DAPI → EVIDE
Every EVIDE account requires preventive identity verification through DAPI.
Generates cryptographic evidence of your identity (always private) with the option of public certification of your online content
Designed for takedown requests, legal proceedings, and cooperation with law enforcement
Manually handled by a forensic expert with 24 years of experience, no automation, no AI processing
Source files deleted within 48 hours; only the elements set out by policy are retained (non-reversible cryptographic hashes, timestamp, metadata)
Qualified time evidence with legal effect throughout the EU and internationally recognized standards
We do not store, catalogue, or search your biometric data as a permanent repository
Your verified identity baseline always remains private. Only publications certified with DAPI-PUB have a public record
No algorithms, no AI validation, no mass processing: every certification is personally supervised
DAPI creates technical documentation for personal legal protection, not corporate identity verification
We provide elements useful in supporting your position; we cannot control platform decisions
DAPI packages may include FEDIS (Forensic Evidence Declaration & Integrity Statement), a technical statement documenting methodology, integrity elements, time references, and other elements useful for understanding and assessing the digital evidence.
FEDIS does not determine the admissibility, evidentiary weight, or outcome of a proceeding. Such assessments rest with the judge or competent authority according to applicable procedural and evidentiary rules.
Within the European Union, the qualified elements used in the process, such as the qualified electronic timestamp, produce the effects provided for by the eIDAS regulation. Use of the package in other jurisdictions must be assessed according to the respective applicable rules.

Anteriority, integrity, and identity consistency
When deepfake, voice cloning, or impersonation occur, platforms and authorities ask the same question: "How can we verify which is the authentic reference and which is the disputed content?"
Without a pre-existing verified baseline, answering this question becomes much more difficult. DAPI creates that baseline before you need it.
Verifiable proof of the existence of your identity materials at a specific date and time, before the fake content appeared.
Cryptographic hashes allow verification of whether files subsequently presented match the certified files: a change to the content produces a different hash.
Establishes a consistent baseline of your appearance, your voice, and your identity documents for verification and comparison purposes.
Cryptographically links your verified identity baseline to specific content you have published online, with a verifiable public record.
The files that establish your verified identity baseline and (optionally) your online content
DAPI certification is based on identity-related files that establish your verified identity baseline. With DAPI-PUB (Public certification of identity and certified content), you can also certify your published online content.
Valid government-issued ID (passport, national identity card, driving licence)
Frontal photo establishing your appearance for the baseline
Audio sample certifying your vocal characteristics
Short video for enhanced authentication (optional but strongly recommended)
Each file is processed to generate a SHA-256 cryptographic hash (fingerprint), which is then certified with an eIDAS-compliant qualified electronic timestamp. The qualified timestamp benefits from the presumption of accuracy of the date and time indicated and of the integrity of the data with which they are associated; the hash allows subsequent verification of the file's correspondence with the certified fingerprint.
In addition to the private identity baseline, you can certify specific content you have published online, creating verifiable public evidence of the link between your identity and that content.

Three controlled steps from request to certified delivery
Fundamental principle: no public upload of identity data. No permanent storage. No automation. Every step is controlled, private, and expert-supervised.
Submit a certification request through our website. No file is uploaded at this stage.
Your files are checked and processed using forensic methodology developed over 24 years of experience.
You receive the complete documentation, designed to support legal and evidentiary use. The source identity files are then deleted.
Your source biometric files are not retained as a permanent repository after certification delivery. DAPI does not retain the original source files as an archive: for certification, only the elements set out by policy are retained (cryptographic hashes, timestamp, and metadata necessary for verifiability), plus any elements voluntarily published through DAPI-PUB.
Complete package designed for legal use and verification
The complete certification package is designed to be immediately usable for legal proceedings, platform disputes, and cooperation with law enforcement. Contents vary depending on the path chosen.

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:
Third parties (courts, platforms, authorities) can then recalculate the hashes of your files and verify that they match the certified hashes, allowing them to verify that the files correspond to those certified and that they were associated with the timestamp issued at the time of certification.
Real scenarios where forensic proof of identity matters
DAPI provides defensive elements for a wide range of digital identity misuse scenarios, from everyday impersonation to the most sophisticated AI-based attacks.
Once a deepfake exists, proving what your authentic reference is becomes much more difficult without pre-existing certification. DAPI establishes your verified identity baseline BEFORE the abuse, creating reference material that can be used in subsequent verifications, disputes, or specialist analysis.
Someone creates social media accounts, dating profiles, or business profiles using your name, your photos, and your personal information to scam your contacts or damage your reputation.
DAPI provides: a verified baseline of your appearance and identity, in support of takedown requests to platforms.
Recommended path: DAPI-IDS (Private certification of the verified identity baseline - suitable to support takedown requests)
AI-generated videos show you making statements you never made, appearing in compromising situations, or endorsing products/causes without your consent.
DAPI provides: your certified facial features at a specific date, usable as reference material in any disputes or analysis.
Recommended path: DAPI-IDS (Private certification of the verified identity baseline) + consider DAPI-PUB (Public certification of identity and certified content) if you are a public figure

DAPI provides: a visible badge and public record, allowing content verification without involving DAPI directly.
Required path: DAPI-PUB (Public certification of identity and certified content - maximum visibility and protection)
Children vulnerable to fake accounts, AI-generated explicit content, parental impersonation scams, grooming through fake identities, or custody disputes with fabricated evidence.
DAPI provides: a verified baseline of a minor's appearance (with parental consent), available before any abuse occurs, with a time reference useful for legal matters.
Recommended path: DAPI-IDS (Private certification of the verified identity baseline - maximum privacy for minors)
Executives, politicians, journalists, or public figures targeted with deepfakes, fake scandals, or voice-cloned statements that can cause reputational or market damage.
DAPI provides: a pre-existing verified identity baseline, available for crisis management and any legal action.
Recommended path: DAPI-PUB (certified public communications) + DAPI-IDS (private defensive baseline)
DAPI provides defensive technical documentation, but does not actively monitor or remove content. For complete protection, you can combine DAPI with these complementary services:
Optimal strategy: DAPI certifies your verified identity baseline before abuse occurs (preventive defense). If abuse occurs, you can use CertifyWebContent to capture the evidence, MonitoraggioDellaReputazione to monitor and remove fake content, and DAPI-PUB to make your certified content publicly verifiable.
DAPI's value is defensive: it does not control the internet, but strengthens your position when you need to act. Think of it as forensic insurance: material you hope you never need to use, but valuable when you need it.
Practical guide for legal and defensive use
The certified DAPI package is designed for immediate use in defensive and legal contexts. How you use it varies depending on the path chosen.
Use case: fake profile, unauthorized use of images, impersonation on social media
Note: the certified documentation can provide elements that platforms consider when assessing requests. It is not possible to guarantee response times or outcomes, which remain at the platform's discretion.
Use case: deepfake defamation, identity theft, fraud, revenge porn
With DAPI-PUB (Public certification of identity and certified content): if the case involves content you have published (e.g. manipulated video, falsely attributed articles), the timestamped public record provides verifiable proof that the content existed at a certain date.
Legal value: within the European Union, the qualified electronic timestamp produces the effects provided for by the eIDAS regulation. Admissibility, weight, and evidentiary effects in each individual case are determined by the competent authority according to applicable rules.
Use case: unauthorized data processing, right to erasure, personality rights violations
Note: DAPI can provide documentation supporting the identification of the data subject, without prejudice to the data controller's ability to apply its own verification procedures and request further elements.
Use case: disputed video/audio authenticity, forensic analysis required
Technical note: the certified baseline provides certified reference material that can support technical comparison by experts or specialist tools.
Use case: content theft, plagiarism, unauthorized republication, video/article manipulation
Distinctive element: the visible badge on original content acts as a deterrent before theft occurs. When it does occur, the public record can facilitate verification by third parties during resolution.
Proving who you were before, not who you are now
DAPI serves to demonstrate what your real identity was before any abuse, cloning, or impersonation.
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 the appearance of fake, manipulated, or unlawfully attributed content.
DAPI creates time evidence predating the abuse, based on cryptographic hashes and qualified timestamps, designed to support legal and evidentiary use with independent verifiability.
Having a certified baseline can allow you to act more promptly, reducing the need to reconstruct certain identifying or temporal elements after the fact during legal actions or takedown requests.
DAPI can help reduce the ambiguity that sometimes leads to hasty judgments by the public, the media, or platforms, by offering reference elements before a situation worsens.
With DAPI-PUB (Public certification of identity and certified content) - proactive public protection: in addition to the defensive baseline, DAPI-PUB adds a layer of proactive public protection: the visible badge and verifiable public record act as a deterrent before content theft occurs, and can facilitate verification by third parties when it becomes necessary to trace back to the certified content.
