After you purchase the Deeper product, follow this guide to upgrade Deeper in Connect.

Deeper Function Overview

Deeper is an end-to-cloud AIGC detection capability offered by ZOLOZ. It combines multi-modal algorithms, terminal injection security detection, and dynamic risk control strategies to identify AIGC risks during identity verification from multiple dimensions.

Deeper is not an independent product; rather, it enhances features in products like RealID, Face Capture, and Connect. For more information, seeWhat is Deeper.

Deeper Upgrade Guide

1. Purchase Deeper Products

2. Upgrade Native SDK Version

• From version 1.4 onwards, the Native SDK includes enhanced terminal control capabilities. To fully utilize Deeper, we recommend upgrading your Native SDK to version 1.4 or later. For specific version numbers, refer to the Release Notes.

• Note: SDK versions 1.4 and above do not require additional NearX dependencies. If you previously used NearX features, you must remove the NearX implementation lines after the upgrade to avoid execution conflicts. Refer to the App SDK-mode integration.

3. Configure deeperMode Input Parameter:

   When you enable Deeper through deeperMode, the parameters serviceLevel and operationMode become inactive, and the detailed product config parameters take effect. The following table lists recommended standard configurations for detailed product config parameters. These values are for reference only; you can adjust them based on your business needs. For more information, refer to the initialize API.

Field name	Description	Example
livenessMode	Specifies the liveness level for face liveness detection. Valid values: CLOSED: No algorithms are applied. Use this mode during testing so that algorithms and risk control rules do not affect the testing process. STANDARD: Default value. Applies a standard recommended level. LOOSE: Applies a looser level. Use this mode in low-risk scenarios. STRICT: Applies a stricter level. Use this mode in high-risk scenarios.	STANDARD
actionCheckItems	User actions to detect. For a better user experience, we recommend using no more than two actions. Valid values: FACEBLINK: Default value. Requires the user to blink their eyes. MOUTHOPEN: Requires the user to open their mouth once. HEADSHAKE: Requires the user to shake their head. Left or right headshake will be specified for the user to perform. HEADLOWER: Requires the user to lower their head once. HEADRAISE: Requires the user to raise their head once.	FACEBLINK+1 other action (for example, MOUTHOPEN, HEADSHAKE, HEADLOWER)
actionRandom	Specifies whether the actions inactionCheckItems are detected in random order. Valid values: Y: Random N: Not random. Actions are detected in the order specified in actionCheckItems.	Y

Relationship Between antiInjectionMode and Deeper

In the Connect initialize API, the antiInjectionMode parameter was a trial feature switch for detecting injection attacks. As of June 2024, this parameter is no longer effective. ZOLOZ has launched the Deeper product, which covers both Deepfake detection and injection attack detection. To enable these features, purchase the Deeper product and set the deeperMode parameter. See theDeeper Upgrade Guide.

Note:

• For existing customers still using antiInjectionMode, ZOLOZ retains this parameter temporarily to ensure API compatibility and a smooth transition.

• If existing customers enable deeperMode parameter, ZOLOZ prioritizes deeperMode, and antiInjectionMode becomes invalid.
