  Note： When it is detected that a HKID document is captured via Web SDK, a multi-angle capture approach will be enabled.
• REALID0003: If this value is set, the ZOLOZ SDK automatically scans the identity document. The ZOLOZ server performs advanced spoofing checks, and performs a liveness check using any of the 2 user actions below randomly. This service level is only for Native SDK.

• Multi-action detection methods include: Blink, mouth open, head up, head down, head shakes (left), head shakes (right) 

• REALID0004: If this value is set, the ZOLOZ SDK automatically scans the identity document even when at an angle. The ZOLOZ server performs basic spoofing checks, and basic liveness checks using the blink detection method.
• REALID0009: If this value is set, the ZOLOZ SDK automatically scans the identity document. ZOLOZ performs an advanced spoofing checks and performs a liveness check using the blink detection method. This service level provides the ability to capture closed-eye images for Native SDK.

• LOOSE: A relatively looser level is applied. You can use this operation mode in low-risk scenarios.
• STRICT: A relatively stricter level is applied. You can use this operation mode in high-risk scenarios.
• STANDARD_VC_CLOSED: You can use this operation mode to disable Velocity feature.
• STANDARD_IDN_CLOSED: You can use this operation mode to disable IDN feature.
• STANDARD_VC_IDN_CLOSED: You can use this operation mode to disable Velocity feature and IDN feature.

Note: When the value is set to STANDARD_VC_CLOSED, STANDARD_IDN_CLOSED or STANDARD_VC_IDN_CLOSED, other algorithm capabilities are the same as STANDARD.

Here are the definitions for IDN and Velocity:

• IDN: indicates that a fake attack risk is detected through the ID network check. For example, a face is detected associated with multiple IDs, or an ID is detected associated with multiple faces. For more details, see checkresult |API Reference.
• Velocity: indicates that a fake attack risk is detected through the velocity check. For example, the number of attack (e.g. fake ID or liveness attacks) attempts by the same user (identified by userId, ID number or deviceId) in the past period of time reaches a certain threshold, the velocity check will not allow user further submission until the cooldown period has passed.
