Originally developed as part of forensics court-expert activities, CertiPhoto can date a photo securely and ensure that it has not been tampered with since the shot was taken. CertiPhoto hence gives probative value to your photographs by establishing a digital evidence of a visual situation, in a particular place, at a particular time.
Each picture you take with this app is encrypted, geolocated, stored on a secure remote server and then sent in a signed email to the user along with a certificate. This certificate is an unfalsifiable PDF document, signed and timestamped by a trusted authority, and has legal value in EU countries.
The electronic signature [must be] uniquely linked to the signatory, be capable of identifying the signatory, be created using means that signatories can maintain under their sole control, be linked to the electronic document to be authenticated. This is to ensure that any subsequent change in that document is detectable. ( Directive 1999/93/EC of the European Parliament and of the Council of December 13th 1999 on a Community framework for electronic signatures ).
CertiPhoto uses advanced cryptographic techniques to build a secure channel between your smartphone and certification servers.
