2018/05/16	V1.8	Optimized the project structure and integration experience. Fixed the problem for phones with the aspect ratio of over 2:1, which are easy to lose track. Adjusted adaptation of Sample UI on iPhone X.
2018/04/20	V1.7.1	Changed the name of the enumeration value of SilentLivefaceErrorType.
2018/01/12	V1.7	Updated model to improve the accuracy of blocked face detection. Added error prompts for eye, nose. and mouth blockage. Added return of request_id to facilitate record visits. Added the pass condition for silent liveness detection will return an error code when the setting is incorrect. Added a sample that stores the frame selection image locally in order to facilitate the recording of the issues of liveness detection.
2017/10/10	V1.6	Customized the judgment conditions of the face distance. Added camera orientation setting parameters for iOS input interface, supports external images/camera forwarding.
2017/09/19	V1.5	Updated the liveness detection model to increase the detection rate of spoofing attacks. Supported blocked face detection, such as by sunglasses or face masks. Released interface to configure path conditions for silent liveness detection to allow customization of the shortest detection time. Added state detection for faces that are completely within the screen to ensure the integrity of the face image collected by liveness detection. Improved error code consistency.
2017/07/14	V1.4	Updated the underlying algorithm library and model. Improved the passing rate for the correct person and the detection rate for spoofing.
2017/04/17	V1.3	Modified the delegate for successful liveness detection. Successful liveness detection will return the data_id, which is then made available to the cloud face comparison interface.
