Active Liveness Detection
This method of PAD is recommended for applications where the security is paramount or where legislation obliges the user to respond to a random challenge.
Innovatrics IDV Toolkit provides these types of active liveness:
- Smile liveness - challenges the user to smile
- MagnifEye liveness (deprecated) - challenges the user to focus camera on his eye
The Smile liveness is a semi-passive method of liveness and provides excellent user experience with a positive emotion and fast time to capture. The Multi-Range liveness provides higher level of security with a randomness factor that might be required by legislation.
Smile liveness
The Smile liveness collects the selfie of a person with different face expressions. It guides the user to position his face properly, and then to change the face expression. The client component collects multiple photos and puts them into a proprietary file format for safe transfer to the server. This allows also the Video Injection Detection to be evaluated.
The threshold for Smile liveness has to be set up in the same way as for Passive Liveness.
Multi-Range liveness
The Multi-Range liveness asks the user to capture multiple selfies. Before the client capture component is used, it is necessary to initiate the client-server session by generating the challenge on the server. The component also puts multiple images into a proprietary file format for the Video Injection Detection.
The threshold for Multi-Range liveness has to be set up in the same way as for Passive Liveness too.
