Evidence built at every step

CertiPhoto does more than add a date to a file. It controls the capture, consolidates useful data and produces a signed document whose integrity can be verified without any time limit.

Controlled capture

The photo or video is created inside the app so checks can be applied when the evidence is produced.

Enhanced geolocation

The position is consolidated by cross-checking available GNSS/GPS, mobile cell, Wi-Fi network and IP address signals.

Signed certificate

Evidence data and SHA-256 fingerprints are brought together in an electronically signed PDF/A-3B certificate.

Long-term verification

The identifier, QR code and signature make it possible to check the integrity and status of the certificate later.

Secure archiving in France

Certificates are securely and redundantly archived across three data centres located in France, in accordance with NF Z42-013 and ISO 14641.

Retention and verification

Photographs are retained for 3 years for individuals and 10 years for businesses. Videos are retained for 90 days. In all cases, the PDF/A-3B certificate and its verification remain available without any time limit.

What CertiPhoto evidence establishes

CertiPhoto documents the creation of a photo or video inside the app, its available technical context, timestamp and integrity. These elements trace the file from capture to certificate.

A CertiPhoto certificate establishes a complete technical chain of evidence: document origin, file integrity, timestamp, capture context and performed checks. These objective, verifiable and durably accessible elements strengthen its evidential value and provide solid support in the event of a dispute.

Photo proof for building permit

Photo, video, certificate: complete evidence

CertiPhoto supports both occasional use and professional deployments: mobile capture, PDF certificate, portal access and public verification.

Certified photo

A picture taken from the app, timestamped, geolocated when available and sealed in a PDF certificate.

Certified video

A video sequence linked to digital fingerprints, proof artifacts and a signed certificate.

Public verification

Each certificate can be checked online using its identifier, QR code or verification link.

Take a picture

Take a shot easily as you would with any smartphone, and add a comment to your photo if you want or need to.

Geolocate

Enhanced geolocation does not rely on GPS alone. Depending on availability, CertiPhoto cross-checks GNSS/GPS data, mobile cells, Wi-Fi networks and the IP address to detect inconsistencies and consolidate the capture location. Certification remains possible without geolocation when no usable signal is available.

Certify

Confirm your choices, send the picture and... that's all! You'll get the picture certificate by email in a few seconds.
Take a shot, geolocate, certify

Digital picture certificate

Each certificate is self-contained, which means all cryptographic data are embedded to be checked with no limit in time. There is no dependency whatsoever with an external entity which could potentially be corrupted, as a Blockchain for instance.

More than just a PDF document

When it comes to documents management, PDF/A ISO standard has established itself worldwide since its launch in 2005. It is platform independent and designed to achieve long-term archiving of electronic documents.

  • QR-code validation(1)

    By flashing this code, you can instantly get an attestation of conformity containing the picture details, at any time.

  • Electronic signature and secure timestamp(2)

    This inset provides access to the signature properties of the document, including information from the trusted third party that provided the secure timestamp. All certificates used are embedded in the document.

  • Picture data(3)

    Data related to the picture are recorded in this paragraph along with a cyphered security chain. They are included in the EXIF metadata as well.

  • User data(4)

    The distinctive details of the device which took the picture, as well as the identity of its author, are captured here.

Privacy and access control

Photos and certificates are not publicly indexed. Access relies on account permissions, certificate-specific identifiers and the sharing mechanisms selected by the user.

No ads

The interface does not disturb your user experience with advertising, and your personal data will never be exploited by third parties or for commercial purposes.

24/7 support

Depending on your requirements, CertiPhoto can provide technical support by e-mail and/or phone, as well as several service level agreements.

Scalable REST API

CertiPhoto is a complete information system with a proprietary storage cloud, a powerful API and multiple database management user interfaces.

Business solutions

Businesses use a portal to attach team members, share credits, define quotas and retrieve certificates created in the field.

CertiLink simplifies mobile deployment, while the API provides authorised access to certificates, metadata and files from an external information system.

Workflows can be adapted to business applications by pre-filling context, controlling access and connecting existing operational tools.
