Anonymous face, eye & voice biometric authentication as a service:
The BioID® Web Service

BioID® Web Service (BWS) – the world’s first ‘biometrics as a service’ – is the product that makes a variety of biometric authentication applications possible. BWS is geared towards application developers of any service or software with access to the internet. BWS has been developed with the three clear principles ‘cloud-based by design’, ‘privacy by design’ and ‘security by design’. You can try out our biometric service in our Playground.


Cloud-based by design

Easy to implement, scalable, cost-effective and available everywhere, anytime, on any device


Privacy by design

Anonymous recognition without personally identifying information


Security by design

Fraud prevention by means of patented anti-spoofing liveness detection

BioID® Web Service
powerful biometrics implemented easily

Offered as an API service, the BioID® Web Service is easily integrated into any existing application infrastructure. Biometric data is kept anonymous to protect user privacy and is completely under the control of the service provider. As a cloud service, it dynamically scales up to any performance and storage requirements, making it available at all times and applicable for a wide range of usage scenarios. The BioID® Connect service lets you integrate quickly using standard protocols, while the BioID® mobile app makes it especially easy to integrate BWS with your mobile apps and mobile websites.

Users are managed in BWS via an anonymous ID, providing privacy-protecting separation of biometric data and other personally identifying information: we have no way of knowing who your users are, and you don’t have to manage any biometric data. This design is especially directed to facilitating GDPR compliance through strong data protection and pseudonymized data handling.

BioID® Web Service (BWS) is a cloud-based online service providing powerful multimodal biometric technology to the customer. User presence is verified through highly accurate face, eye and voice recognition, which is as intuitive and user-friendly as taking a selfie and as trustworthy as a face-to-face transaction. Implemented as ‘Biometrics as a Service’ it can enhance the security of existing infrastructures in an easy way, avoiding costly redesign and reimplementation. It enables advanced, enterprise-grade biometric recognition available to everyone, on any device, anytime, anywhere, with dynamic scaling for reliable performance and availability.

Integration is simple and flexible with no on-premises software to install or maintain, simply a choice of SOAP or RESTful APIs, so developers can concentrate on their core applications and leave the biometric service – as well as the data storage – to us.

BioID® Web Service at a glance
The fastest path from code to customer

  • Enroll – Registration and training of face, eye and voice traits for the following authentication processes
  • Verify – “Are you who you say you are?”: One-to-one matching for biometric authentication for online login, identity proofing, transaction authorization, etc. including our photo/video fake defender
  • Identify – “Who are you?” or “Are you on the list?”: One-to-many matching for detecting duplicate registrations and users of special interest (e.g. blacklist), for online registration, background check, etc.
  • Liveness Detection – “Are you really there?”: Patented anti-spoofing fake detection against photo and video replays for preventing identity fraud, e. g. for legally binding actions or financial transactions
  • PhotoVerify – “Are you the one on the ID?”: Automated identity proofing through high-quality comparison of ID and person, e. g. for opening a bank account or for ID renewal
  • Quality check – High-precision image quality check to ICAO & ISO/IEC standards for e-passport/ID photos, mug shots
