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.

Why use IDifier?

Commissionless online marketplaces
Use IDifier prior to buying or selling an expensive item (e.g., a high-end watch) on a forum or commissionless online marketplace. Verify the identity of the other party and avoid getting scammed out of your cash or your item. Use the location tracking function to verify home and work locations before shipping an item or wiring money.

Online personals
Feel more comfortable meeting people online, even if everyone is using an alias. Check their IDifier profile to verify their age, location, or profession. Be assured that your contact has first registered his true identity with us.

Anonymous but credible web posting
Convince others that your review, blog post, or Wikipedia edit is credible without having to reveal your complete identity. For example, you edit a Wiki article on Computer Science and you want to prove that you know what you are talking about. In your edit info, just add a link to your anonymous IDifier profile that displays CS professor as your verified profession.

How IDifier Works

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 cloud (on Digital Ocean servers in Frankfurt, Germany) following security and privacy best practices. IDifier's treatment of your personal information is fully compliant with:

General Data Protection Regulation (GDPR) (Regulation (EU) 2016/679) by which the European Commission intends to strengthen and unify data protection for individuals within the European Union (EU) and address the export of personal data outside the EU.

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.

How it works diagram

Personal Information

Create an IDifier account and enter your identity information like name and surname, your contact info and your address. Your data will be verified with various means and fake information will be detected.

Address Verification

Declare your home and work address. Take a photo of your utility bill or enable infrequent and privacy-preserving location tracking to allow IDifier to verify your location.

ID document photos

Take photos of your ID document and your face. To preserve your privacy and prevent identity theft, you have to crop several fields of your ID document photos before they can be verified. Also, watermarking is employed.

Bind together your online identities

User's have different online identities for each of the services they use such as email and social network accounts. Connect from your IDifier profile to your Facebook and Google+ accounts to verify your declared information and link those accounts with your IDifier online identity.

Peer Auditing

Audit the identity information (attributes) of other users, while other users audit yours. This is a simple process where everyone helps each other to prove their identities. You will be notified when you have audits to do. We use smart algorithms when assigning audits to ensure that auditors cannot reconstruct your complete identity from the fragments they see.

Prove your identity

Create temporary profiles choosing the identity information that you need a user (verifier) to check and share it with this user. To prevent re-use of your profiles, specify a context and an expiration time for each profile you create.

How secure is it?

IDifier attempts to approach and even exceed the level of security users obtain when they examine each other's electronic or physical copies of a passport.

Advantages over examining electronic copies (e.g., sent through email):

We do automatic image recognition to detect suspected fake ID documents.
We provide additional eyes (auditors) to help you.
We protect your privacy by not having to share with unknown people a high-res photo of your ID document (that they might then use to impersonate you).
We protect your privacy by permitting you to prove your identity without even having the verifier looking at your ID document. Instead you just share proofs that others have audited you.

Advantages over examining physical copies:

We do automatic image recognition to detect suspected fake ID documents.
We provide additional eyes (auditors) to help you.
We protect your privacy by permitting you to prove your identity without even having the verifier looking at your ID document. Instead you just share proofs that others have audited you.
If somebody uses image manipulation software to falsify a passport by e.g., pasting his image to it then you have on record the photo of the perpetrator along with proof of the falsification. This can later on help the police investigate and to secure conviction. With a fake passport presented in physical form it is quite unlikely that you will have the same evidence.

Is verifying my identity secure?

The information you provide IDifier during the Identity Verification process is governed by our Privacy Policy and transmitted using SSL-the same secure encryption that websites use to transmit credit card numbers.
When we receive information from your Identity document, we store the number in a secure and encrypted form, so you should only have to verify your ID once. For countries with knowledge-based authentication, we don't store the questions or your answers.
Only a small number of authorized IDifier employees are allowed access to your original documentation for troubleshooting or internal purposes.
