Combatting identity fraud on the Internet

IDifier helps you make sure that people you meet online are who they claim to be. It convinces you of their identity as if you had met them in person at their home or work location and they handed you over their photo ID.

IDifier is an essential tool for any online service that needs identity verification, such as online marketplaces, online personals, as well as scores of others from the collaborative consumption and crowdsourcing movements.


IDifier asks you to input your personal information, along with documents, photos, and GPS signatures that can be used to audit it. It then performs automated and human-driven face and character recognition, as well as location detection to verify and connect all your claimed identity attributes.

Watermarking, cropping and elaborate algorithms are used to ensure that nobody has access to reusable or forgeable pictures of your ID documents and that your security and privacy is preserved.

Your identification data are stored securely on the Amazon cloud (on Amazon servers in Frankfurt, Germany) following security and privacy best practices. IDifier's treatment of your personal information is fully compliant with:
  • Directive 95/46/EC of the European Parliament and Council of 24 October 1995 on the protection of individuals regarding the processing of personal data and on the free movement of such data.
  • Directive 2002/58/EC of 12 July 2002 concerning the processing of personal data and the protection of privacy in the electronic communications sector.


When your identity, or parts of it, have been audited and validated, you can then share profiles to prove parts of your identity to verifiers. The profiles are just special URLs, which can be shared easily with anyone who needs to verify your identity.

Verifiers can be other users, e.g., a person with whom you communicate with on a dating site. They can even be online services, such as a betting site that wishes to verify whether a user is over 18. Verifiers do not need to have registered with IDifier to view your profiles.

With IDifier, users have the option to remain anonymous when other users or businesses verify attributes of their identity. At the same time, a verifier knows that IDifier can hold a user accountable for his transactions.
