This API operation initiates a Face Liveness session. It returns a SessionId
,
which you can use to start streaming Face Liveness video and get the results for a
Face Liveness session.
You can use the OutputConfig
option in the Settings parameter to provide an
Amazon S3 bucket location. The Amazon S3 bucket stores reference images and audit
images. If no Amazon S3 bucket is defined, raw bytes are sent instead.
You can use AuditImagesLimit
to limit the number of audit images returned when
GetFaceLivenessSessionResults
is called. This number is between 0 and 4. By
default, it is set to 0. The limit is best effort and based on the duration of the
selfie-video.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCreateFaceLivenessSession and EndCreateFaceLivenessSession.
