Our patents

We have invested heavily in patenting our technology.  As an early innovator in reusable digital identity, AI-powered age estimation and AI-powered identity authentication technology, we have a diverse patent portfolio with some early priority dates.  

As of February 2020 we have 15 granted or allowed patents, including the following:

Granted patents

Registering an ID document

This patent covers the way we register ID documents, like passports and driving licences to anchor an individual’s digital identity. It covers the way one gains confidence that the photo ID is submitted by the genuine individual, and how four systems (registration, enrolment, administration and authorisation) work together. This also covers our mechanism of generating receipts which record ‘shares’ between Yoti users and Yoti organisations.

Patent number: US2016239653

Web content

This is a patent for mutual authentication of the web content provider and the end user using authentication tokens (one time credentials) that can be exchanged through different methods such as QR code, web deep links, NFC (Near Field Communication), BLE (Bluetooth Low Energy).

Patent number: US2016241532

Attribute exchange

Here we focus on enrolment, credential creation and the publication process. It includes the creation of a ‘sharing token’, which enables personal attributes to be shared.

Patent number: US2016239657

Sharing of attributes

This is a very valuable patent that described the process of taking data from a document remotely, and using that data to create identity credentials.


Authentication of bearer

A process of sharing one time credentials in order to exchange attributes. This patent has applications in the Internet of Things.


Two factor liveness detection

This is our process of using multi modal (two or more) 'liveness' tests (which may include biometrics) to help us to prove that people are who they say they are in a set time frame. In our granted patent one of the liveness tests must have an element of randomly generating a test, e.g. showing random words on the screen or a random facial expression (like a wink).

Patent number: US2017048244

Encryption of attributes

This is the first patent granted that covers the precise way that the Yoti app operates. It covers the clever sharing mechanism that allows Yoti to share an attribute with a relying party whilst Yoti itself cannot see or decrypt the attribute itself.

Patent number: EP3257223

Verification of physical assets

This covers the method of attaching a QR card to a physical asset, like a bank card, and then unlocking the asset by using the QR code and a digital identity system to prove your identity as the correct recipient of the asset.

Linking assets to a digital ID

This is an extension of the ‘core commercial’ system patent. It describes how assets can be associated with a digital identity (derived from a trusted document) and then transferred to another digital identity. A trail of the transfers is recorded to prove ownership. The asset can be a card, title deed or valuable piece of equipment.


Linked payments and digital ID

The method in using a digital ID system to transfer an ID attribute at the same time as using the digital ID system to make a payment. It covers payment tokenisation allowing payments from user to merchant without the merchant having to store or receive any payment details.

Facial Anti-Spoofing

A method of correlation of a face to sensor data on a device, based on movement of the device in relation to the face presented to it.

Anti touting

This is our original anti-touting patent, which stops ticket bots by associating tickets to a digital identity and then analysing past behaviour of ticket purchasing, event attendance and use of tickets to decide whether a particular person is a ticket tout, and therefore whether they should be sold a ticket or not.


Auditable identity receipt system

Similar to the registering an ID document patent, this one is for an auditable receipt generation module and our master receipt book.


Behavioural biometrics

An anti-spoofing test which analyses the actual movements of a personal device when being moved by an individual, compared with the precise movements the system expected that specific user to make.

Patents we've applied for

Our ‘core commercial’ system

This combines four separate patent applications (some already granted) to describe how our ‘core’ system works. It covers registering documents, splitting attributes, storing attributes, sending a policy from someone’s device and then sharing the attributes with the person requesting them.

Application number: PCT/EP/2016/053076

Yoti Connections and anti-ticket touting

The process of establishing a time-stamped connection between two or more people who have been verified by Yoti, and then sharing that connection with a third party. This is particularly focused on anti-ticket touting. Ticket touts do not know at the point of payment for tickets who will be using the tickets because they will be re-selling. Yoti Connections allows buyers to establish links to friends, family or colleagues prior to purchasing and then allocating those tickets.

Application number: GB 1715111.9

Computer-implemented tracking

This is a patented system of tying a digital identity to an asset, and then how that asset is transferred to the digital identity of a third party. The owner could be a real person, a legal entity or an employee at a company.

Application number: US2016350861

Liveness detections

Here we have five separate liveness related claims rolled into one patent application. They are: Random words at a random location and tracking eye movement. Heartbeat detection by viewing changes to characteristics of the skin. Specular reflection in the eye (eg showing image reflections in the eye). Person vs background parallax (checking background changes as you expect i yt to). Pupil response to light pulses. US2017046583

Yoti Sign

Our document signing technology, including attribute sharing for signing which allows the parties to have biometric proof of who signed the document. We have a separate set of claims for hashing together hashes of signed document content and the identity attributes used to biometrical prove who the signers are.

Application number: GB 1808656.1

Smart contracts

A method of associating one or more verified identity attributes with a smart contract on the blockchain. The smart contract and identity attributes are hashed together so that no substitute smart contract can be put in its place.

Application number: GB 1813458.5

Yoti Keys

A patent covering our Yoti Keys. These are NFC enabled physical ‘keys’ which can hold encrypted personal attributes, which can then be transferred to a tablet if the user taps the key against the NFC reading part of the tablet. This is most useful in areas with poor mobile signal or for users who do not wish to use a mobile phone based reusable ID system.

Depth detection

This is an extremely exciting R&D project to train a machine learning model using 3D and 2D images as input to produce a model that can detect depth in a 2D image.
