DAPI-PUB use cases: real examples of identity and content verification
DAPI-PUB is a public certification system that allows a verified identity to be associated with specific digital content and elements submitted for the certification process. It is not a social network or a publishing platform: it makes publicly consultable verification records available for certified elements.
The examples on this page are illustrative scenarios created to show possible ways of using DAPI-PUB. The names, situations, and outcomes described do not necessarily represent real cases or guaranteed results.
Why DAPI-PUB is different
Manual verification
Not automatic. Each identity is manually checked according to a verification and document review procedure.
Technical documentation
Designed for evidentiary contexts through technical elements such as cryptographic hashes, time references, and documentation signed according to the DAPI process.
Identity and content
Integrated certification: the verified identity can be associated with content specifically submitted for the certification process.
Public verification
Anyone can consult the public record via QR code or listing, without directly involving DAPI.
Content creator and YouTuber
Preventive video documentation and support in content-use disputes
The problem
Marta has a YouTube channel with 50,000 subscribers and creates photography tutorial videos. She discovers that at least 5 channels have re-uploaded her videos without permission, some translating the audio with AI voice cloning and appropriating her content in different languages.
The DAPI-PUB solution
- Certifies each original video via DAPI-PUB with a cryptographic hash and timestamp
- Adds a verifiable DAPI badge as a video overlay (digital watermark)
- Includes the link to verify.dapi-certification.com in the description of each video
- When she finds copies, she can submit a DMCA takedown with the per-video certificate and the link to the public record
- The DAPI record can be provided to the platform as a verifiable documentary element supporting the report
Usefulness in this scenario
Without a preventive baseline: handling a dispute may
require reconstructing evidence of the video's existence and original form.
With DAPI: a certified record and technical reference are
available that can be provided to the platform in support of the report.
Publicly exposed professional
Defense against fake profiles and professional impersonation
The problem
Dr. Paolo Rossi, a financial consultant, discovers 3 fake LinkedIn profiles using his photos, name, and credentials to contact his clients offering fraudulent investments. Confused clients contact him thinking it's really him, damaging his reputation.
The DAPI-PUB solution
- Creates a profile on verify.dapi-certification.com with certified identity
- Adds the DAPI badge to his legitimate LinkedIn profile and company website
- Sends a communication to clients: "Always verify the DAPI badge before responding"
- For the fake profiles, submits a report to LinkedIn with the DAPI certificate and the link to the public record
- The public DAPI record allows showing which profile is associated with the identity baseline verified and declared by the holder
Usefulness in this scenario
Without a preventive baseline: it can be more difficult to show which
account is actually associated with the identity declared by the professional.
With DAPI: a public record is available showing which profile is
associated with the verified identity baseline, usable in support of a
report.
Journalist and science communicator
Article protection and deepfake video prevention
The problem
Giulia, an investigative journalist, publishes reports on sensitive topics. A deepfake video appears in which she seems to say things she never said, intended to discredit her. At the same time, her articles are copied onto fake news sites that attribute false positions to her.
The DAPI-PUB solution
- Certifies her identity baseline with DAPI-IDS (face, voice) before deepfakes circulate
- Publishes a DAPI-PUB profile with all her original certified articles
- When a deepfake appears, she submits the baseline certificate as reference material for analysis and dispute
- The certified record provides a cryptographic and time reference for the content submitted for certification, usable for comparison with subsequently disputed versions
- The DAPI badge on legitimate videos helps followers distinguish certified content
Usefulness in this scenario
Without a preventive baseline: quickly having verified material to
use in comparison with a disputed video can be more difficult,
as can having technical and time references relating to previously
certified articles.
With DAPI: a certified baseline is available as
reference material for analysis and disputes, and publications with time references
usable in comparison with subsequently disputed content.
Artist and musician
Preventive documentation of creative works and audio tracks
The problem
Luca, an independent musician, publishes his original compositions on Spotify and YouTube. He discovers that at least 10 artists have sampled his tracks without credit, and some have registered his melodies as their own compositions.
The DAPI-PUB solution
- Certifies via DAPI-PUB the tracks he intends to document before publication.
- The cryptographic hash of the audio track and the timestamp document the existence of the file in that form at a certain date
- DAPI badge in Spotify/YouTube descriptions with a link to verify.dapi-certification.com
- When he detects possible unauthorized use, he submits the DAPI certificate as a documentary reference for the form of the file submitted for certification and the moment at which that certification was performed
- Rights management organizations can consult the public DAPI record
Usefulness in this scenario
Without a preventive baseline: it can be difficult to have an
independent technical reference for the version of the material available at a given
moment.
With DAPI: a cryptographic and time reference for the
certified track is available, usable as a supporting element in case of disputes.
Trainer and consultant
Preventive documentation of teaching materials and professional methodologies
The problem
Sara, a corporate trainer, has developed a proprietary leadership course. After training several companies, she discovers that 2 former participants are offering "their method" using her slides, exercises, and framework without authorization.
The DAPI-PUB solution
- Certifies all teaching materials (slides, workbook, video) with DAPI-PUB before distributing them
- Adds a DAPI watermark to each slide with a link to verify.dapi-certification.com
- The timestamp associated with the certification documents the existence of the certified materials by the attested time
- Submits a cease-and-desist letter with the DAPI certificates supporting her position
- The former participants are confronted with a verifiable documentary reference
Usefulness in this scenario
Without a preventive baseline: disputes over the use of materials may
rest solely on conflicting claims.
With DAPI: a documentary
reference on the existence of the certified materials is available, usable in support of
a cease-and-desist letter.
Academic researcher
Time documentation of pre-prints, datasets, and research materials
The problem
Prof. Giovanni Verdi is about to publish innovative research in a scientific journal. During the peer review process (6 months), a reviewer uses his preliminary data to publish a similar article in another journal, claiming priority for the discovery.
The DAPI-PUB solution
- Certifies the pre-print and dataset with DAPI-PUB before submitting to the journal
- The timestamp associated with the certification documents the existence of the specific version of the pre-print or dataset by the attested time
- Publishes a certified abstract on verify.dapi-certification.com with a "Research certified" badge
- When an article with similar content appears, he submits the DAPI certificate as a documentary element supporting a possible priority claim
- The technical documentation can be used to support the claim with the journal
Usefulness in this scenario
Without a preventive baseline: it can be more difficult to have an
independent technical reference for the version of the completed research at a given
moment.
With DAPI: a documentary element is available in support of
a possible priority claim with the journal.
Innovative medical protocol
Time documentation of methodologies and professional procedures
The problem
Dr. Marco Bianchi, a physiotherapist, has developed a post-operative knee rehabilitation protocol that reduces recovery time. After presenting it at a conference, he discovers that 3 competing clinics are offering a very similar "proprietary method" without ever crediting him.
The DAPI-PUB solution
- Certifies the complete protocol (PDF document) with DAPI-PUB before presenting it publicly
- The cryptographic hash and qualified timestamp document that the document already existed by that date
- Publishes a summary version on verify.dapi-certification.com with a "DAPI-certified protocol" badge
- Includes the DAPI link in presentations, scientific publications, and on the clinic's website
- When he detects similar methodologies, he submits the DAPI certificate as a verifiable time reference relating to the version of the document submitted for certification
- The public timestamped record provides an independently verifiable reference
Certification concerns the identity, the document, and the related technical elements; it does not constitute scientific or clinical validation of the methodology described.
Usefulness in this scenario
Without a preventive baseline: disputes over who first presented a
methodology may rest solely on informal reconstructions (e.g. "who presented first at
the conference").
With DAPI: a timestamped technical reference is
available for the version of the certified document, usable as a supporting
element.
Specific benefits for the medical field
- Time reference: a verifiable reference relating to the version of the document and the moment of its certification
- Pre-publication protection: certification before conferences or journals
- Credibility element: the DAPI badge signals documentary rigor
- Dispute support: technical documentation in disputes between professionals or clinics
- Value for licensing/training: a certified protocol has a stronger documentary reference
- Methodology: technical documentation inspired by recognized forensic standards
Professional photographer
Verifiable watermarking and counteracting unauthorized use
The problem
Andrea, a wedding and portrait photographer, publishes his portfolio on Instagram and his website. He discovers that stock agencies, other wedding planners, and competitors use his photos to promote their own services, easily removing traditional watermarks with AI tools.
The DAPI-PUB solution
- Certifies each original photo with DAPI-PUB before publishing it
- The cryptographic hash allows verification of whether a compared file is identical to the certified file; modified, resampled, or cropped versions may require further technical comparison elements
- DAPI badge embedded in the image with a QR code to verify.dapi-certification.com
- When he detects unauthorized use, he can submit the certificate as a supporting element for a DMCA request
Usefulness in this scenario
Without a preventive baseline: traditional watermarks can be
removed, making it more difficult to have a technical reference for the original photo.
With DAPI: a cryptographic hash of the original file is available,
usable to verify correspondence with identical copies and as a supporting element for a
report.
Registered trademark holder
Trademark-identity linking and abuse prevention
The problem
Elena has registered the trademark "EcoVita" for organic products. She discovers that at least 5 companies use similar names (EcoLife, EcoVitale, BioVita) selling non-organic products and creating confusion among consumers, who mistake them for her brand.
The DAPI-PUB solution
- Certifies a DAPI-PUB profile linking Elena's verified identity to the documentation of the "EcoVita" trademark submitted for certification.
- Publishes the trademark registration certificate and all official products with DAPI badges
- A QR code on each package links to verify.dapi-certification.com
- Consumers can consult the public DAPI record to verify the certified elements and references associated with the declared holder
- For confusingly similar trademarks, she submits a cease-and-desist letter with the DAPI certificate as a documentary reference associated with the verified identity and the declared ownership of the registered trademark.
Usefulness in this scenario
Without a preventive baseline: it can be more difficult to show which
trademark elements are associated with the declared holder's identity.
With
DAPI: a publicly consultable record with certified references is available,
usable in support of a cease-and-desist letter against confusingly similar trademarks.
Cultural association
Certification of public projects and events
The problem
The association "ArteLibera" organizes cultural events and publishes articles on its blog. A fake association, "ArteLiberaItalia," appears, collecting donations using a similar name and reusing photos and articles from their site, deceiving donors.
The DAPI-PUB solution
- Certifies a DAPI-PUB profile for the association with its statute, tax code, and the president's identity
- Publishes all official events and articles with a verifiable DAPI badge
- Launches a communication: "Always verify the DAPI badge before donating"
- Reports the fake association by submitting the DAPI certificate as a reference supporting the impersonation report
- Payment platforms can assess the report using this documentary reference
Usefulness in this scenario
Without a preventive baseline: it can be more difficult to document
which content and communications are actually traceable to the authentic association.
With DAPI: a verifiable public record is available, usable as a
documentary element in support of a report or complaint; the final assessment
remains up to the platform or competent authority.
Politician and public figure
Defense against election deepfakes and false statements
The problem
Mayoral candidate Roberto Neri, a week before the election, finds himself the subject of a deepfake video in which he "promises" an unrealistic abolition of taxes. The video goes viral, damaging his election campaign.
The DAPI-PUB solution
- Certifies his identity baseline with DAPI-IDS (face, voice) at the start of the campaign
- Publishes a DAPI-PUB profile with all official certified statements
- DAPI badge on all official videos: "This video is DAPI-certified"
- When the deepfake appears, he submits the baseline certificate as reference material for technical analysis, disputes, and verification
- Social platforms can assess the report using this technical reference
Usefulness in this scenario
Without a preventive baseline: responding quickly to a deepfake and
showing which videos are certified can be more difficult.
With
DAPI: a certified baseline and official statements with badges are available,
usable as reference material for technical analysis, disputes, and verification by
platforms.
Documentary testimony
Technical documentation of content associated with a testimony
The problem
Laura witnesses a car accident. She records a video on her smartphone but fears that, in legal proceedings, the opposing party might dispute the video's authenticity, claiming it was altered or created afterward with a manipulated date.
The DAPI-PUB solution
- Laura certifies the video with DAPI-PUB within a few hours of the accident
- The eIDAS qualified timestamp documents the date and time of certification
- The cryptographic hash allows verification that the file matches the certified one and has not been altered since certification
- She submits the DAPI certificate as technical documentation in support of her testimony
- The competent authority assesses the evidentiary value according to the rules applicable to the proceeding
Usefulness in this scenario
Without a preventive baseline: the video's authenticity can be more
easily disputed, potentially requiring a technical expert assessment.
With
DAPI: technical documentation on the file's certification is available, usable
in support of the testimony; the evidentiary value remains subject to assessment by the
competent authority according to applicable rules.
Activist and whistleblower
Identity protection and documentation of sensitive materials
The problem
Marco, an environmental activist, publishes documents reporting possible environmental violations by a company. The company claims the documents are fake, fabricated, and that Marco is an impostor paid by a competitor.
The DAPI-PUB solution
- Certifies his personal identity with DAPI-IDS, with a baseline verified through a certification process
- Certifies the original documents with DAPI-PUB before making them public
- The qualified timestamp documents that the documents existed before publication
- The cryptographic hash allows verification that the documents correspond to those certified and have not been altered after certification
- Media and authorities can independently consult the technical elements
Usefulness in this scenario
Without a preventive baseline: the credibility of the identity and
documents can be more easily disputed.
With DAPI: verifiable
technical elements about identity and documents are available, usable in support of an
independent assessment by media and authorities.
Important note
In cases involving sensitive materials, the level of publication and the elements to make consultable must be assessed based on the type of certification requested and the rules applicable to data processing. DAPI does not require source biometric files to be published on the website.
External evidentiary deposit with EVIDE
Independent temporal anchoring of identity, events, and certified content
The problem
In some cases, certifying an identity or content is not enough. It is also necessary to preserve an independent, temporally documented reference relating to a digital verification, approval, publication, declaration, or decision. This is particularly relevant in legal, audit, dispute, document governance contexts, and preventive protection against subsequent repudiation.
The solution with DAPI-PUB + EVIDE
- The identity verified through DAPI can be used as a reference to associate a person with a specific digital event
- EVIDE allows recording an external documentary reference, independent of the public website alone or the visible publication
- The deposit can verifiably reference identity, content, approvals, declarations, verification events, and time references
- In case of a subsequent dispute, it is possible to show that the event had been recorded, with which elements, and that it was associated with a specific verified identity
- This provides documentary elements usable in legal, governance, and audit contexts, the assessment of which nonetheless remains up to the competent authority
Usefulness in this scenario
Without EVIDE: it can be more difficult to show that a verification,
approval, or publication had already been recorded at a given moment.
With
EVIDE: an external documentary reference is available, usable to show that
a specific event, declaration, verification, or approval had been recorded in the
EVIDE process by a given moment.
When it is particularly useful
- For verified DAPI identities: to document that a reference to a given verification had already been recorded.
- For certified content: to strengthen the documentary reference over time
- For audits and disputes: when an external, independent trail is needed
- For document governance: when a decision or approval needs to remain documentable
- For legal and reputational scenarios: when online publication alone is not considered sufficient
EVIDE preserves what has been declared or recorded and when it entered the relevant evidentiary process; it does not autonomously determine the substantive truth of the event, the correctness of the decision, or the legal authority of the subject.
