Solutions for face.com developers

The popular face recognition API from face.com was recently shut down after their acquistion by Facebook.

BioID Web Service has a face recognition API that could be a viable alternative for some former face.com developers.
It's not identical; there are features face.com had that BioID doesn't support, but BioID can also do things face.com couldn't.

Key differences

  • BioID technology was developed for authentication applications: recognition is far more accurate than typical for photo tagging.
  • BioID provides liveness detection, to detect impostors trying to authenticate as someone else by holding a photo or video in front of the camera.
  • Face detection is more strict (necessary for authentication). This means it will not find faces that are heavily turned or tilted, or extremely small/extremely low resolution.
  • BioID can return the eye position coordinates and/or a cropped image of just the face, but not any further coordinates for face position, nor gender, glasses, etc.
  • Multiple faces: for authentication BioID detects and rejects images with multiple faces, to avoid looking over the shoulders scenarios. For other applications, with multiple faces BioID can return the eye coordinates and/or a cropped image for the best face found.
  • BioID is currently available as a SOAP API, a RESTful version is planned.
  • No usage limits.
  • 30-day free trial, then pricing on a per-transaction basis based on an annual subscription.

Applications

  • Biometric authentication (face & voice; iris coming soon), including liveness detection
  • Biometric identification (one-to-many): identifying people on blacklists, criminal background checks
  • Ticketless check-in: trade shows and other events, airline boarding, ships
  • Fraud prevention: liveness detection to verify presence of a live user; detecting multiple registrations from the same person
  • Face or voice similarity search: celebrity matching, online dating, modeling or casting agencies
  • Photo quality checks to ensure good-quality (biometric) ID photos or mugshots
  • Limited photo tagging when there is only one face in the image and the face is turned relatively straight towards the camera

Not supported

  • Recognizing multiple faces in one image
  • Finding or recognizing heavily turned or tilted faces
  • Identifying attributes such as gender, age, wearing glasses, smiling, etc.
  • Returning location of features other than eyes
