6.3.1. /liveness/silent_detection/stateless

サイレント生体検知のインターフェースです。

リクエストモード

POST

リクエスト URL

http://ip:port/liveness/silent_detection/stateless

リクエストパラメーター

一般的なビデオフォーマットはサポートされています。例えば： .mp4, .avi, .flv, .wmv, .mov, .rm

通常のレスポンス

ここで、liveness_statusの結果は以下のようになる:

{
  "request_id": string,
  "code": int,
  "passed": boolean,
  "liveness_score": float,
  "liveness_status": string,
  "image_timestamp": float,
  "base64_image": string,
  "base64_face_image": string,
}

異常なレスポンス

{
  'request_id': 'xxx',
  'code': xxx,
  'message': xxx
}
