BioID and facesearching both use facial recognition technology, but they serve completely different purposes. BioID is a biometric authentication platform specializing in liveness detection and identity proofing for Know Your Customer (KYC) compliance, online banking, and secure access control. facesearching is a face search engine that helps individuals and businesses find someone by photo across the public web. One verifies that a person is who they claim to be during a live transaction; the other discovers where a face appears online. This comparison clarifies the differences between biometric authentication and web-based face search, helping you choose the right tool for your needs.

Platform Overview
BioID, based in Germany, is a biometric authentication company that provides cloud-based identity verification services. Its core technologies include liveness detection — the ability to verify that a face presented to a camera belongs to a living person and not a photo, video, or mask — and biometric identity proofing, which matches a selfie against a government-issued ID document. BioID is used by banks, financial services companies, and enterprises for KYC compliance, secure customer onboarding, and passwordless authentication. The platform is GDPR-compliant and operates under European data protection standards. facesearching is a reverse face search platform that scans the public web for matching faces. It does not perform liveness detection, does not match against ID documents, and does not provide authentication services. Instead, it helps users discover where a face appears online — social media profiles, news articles, blogs, and video content — providing context for identity verification decisions.

Core Technology: Authentication vs Discovery
The fundamental technical difference is authentication versus discovery. BioID's technology answers the question: Is this person who they claim to be, right now? It does this through liveness detection, which analyzes micro-movements, texture patterns, and three-dimensional depth cues to distinguish a live person from a spoofing attempt. The system then compares the live face to a reference image — typically from a government ID — to confirm identity. facesearching's technology answers a different question: Where does this face appear online? It does this by searching public web sources, matching the uploaded photo against billions of publicly available images, and returning results with context and source links. facesearching is not designed to confirm identity in real time during a transaction; it is designed to provide background information that helps users make informed trust decisions.

Liveness Detection and Anti-Spoofing
Liveness detection is BioID's flagship feature and a critical component of any biometric authentication system. Without liveness detection, an attacker could authenticate using a photo, video, or 3D mask of the authorized user. BioID's PhotoVerify and VideoVerify technologies analyze multiple liveness indicators simultaneously, achieving certification under the ISO/IEC 30107-3 standard for presentation attack detection. This makes BioID suitable for high-security applications like banking, where the consequences of spoofing are severe. facesearching does not include liveness detection because it serves a different purpose. When you upload a photo to facesearching, you are not proving your identity — you are searching for information about the face in the photo. Liveness detection is irrelevant to this use case. However, facesearching's privacy-forward design means that even if someone tried to spoof the system, there is no persistent database to compromise and no authentication to bypass. The system simply searches public web content and returns results. For more on security, see our face search privacy FAQ.
Pricing and Deployment
BioID operates on a B2B SaaS model with usage-based pricing. The company charges per verification transaction, with volume discounts available for enterprise clients. Pricing is not publicly listed on the website but is available through a sales consultation. Integration requires technical development work to embed BioID's APIs into the client's application or website. Deployment is typically cloud-based, with options for on-premises deployment for clients with specific data residency requirements. facesearching offers transparent, consumer-facing pricing: $2 per search, $29 Starter plan, and $79 Pro plan. No API integration, development work, or sales consultation is required. Users simply visit the website and start searching. The difference in pricing and deployment reflects the different target markets: BioID serves enterprises building authentication workflows, while facesearching serves end users who need to search for faces online.

Privacy and Compliance
BioID is headquartered in Germany and operates under GDPR, one of the world's strictest privacy frameworks. The company is certified under ISO 27001 for information security management and processes biometric data with explicit consent and purpose limitation. BioID stores biometric templates (not raw images) for the duration of the customer relationship, in compliance with its clients' data retention policies. facesearching takes a different privacy approach: it does not store biometric data at all. Uploaded photos are deleted immediately after each search, and no facial recognition database is maintained. This ephemeral processing model eliminates the privacy risks associated with biometric data storage. Both platforms are privacy-conscious, but they address different privacy concerns: BioID addresses the privacy of biometric data in authentication systems, while facesearching addresses the privacy of individuals who upload photos for search. For more on privacy, see our face search data privacy FAQ.
BioID answers the question: Is this person who they claim to be? facesearching answers the question: Where does this face appear online? Both are valuable, but they serve completely different needs.
Which Should You Choose?
The choice is straightforward: if you need to verify someone's identity during a live transaction — for KYC compliance, banking authentication, or secure access control — BioID provides the liveness detection and identity proofing technology you need. If you need to discover where a face appears online — for identity verification research, dating safety, fraud investigation, or personal reputation monitoring — facesearching is the tool designed for that purpose. The two platforms are complementary, not competitive. In fact, many organizations use both: BioID for real-time authentication during customer onboarding and facesearching for background research on high-risk customers or counterparties. For most individuals and small businesses, facesearching is the more relevant tool because it addresses the everyday need to verify identities in online interactions.
