    Data Security Center:Classify and grade data using AI large language models

    Last Updated:Jun 22, 2026

    Data Security Center (DSC) now supports sensitive data classification and grading through a hybrid architecture that combines AI large language models (LLMs), expert small models, and traditional regular expression rules. This approach significantly improves coverage, accuracy, and intelligence over regular expressions and keyword rules alone.

    Key improvements:

    • Upgraded detection capabilities
      Combines the Qwen LLM and domain-specific expert small models to automatically detect over 800 data types, covering structured data (database fields) and unstructured data (documents, images, and logs).



    • Improved detection performance
      Overcomes limitations of traditional rule-based methods when detecting content with implied semantics, varied formats, or context-sensitive information, significantly increasing accuracy and recall.



    • Flexible configuration and efficient response
      Supports custom classification and grading policies with millisecond-level inference, meeting compliance and administration requirements across business scenarios.



    • Seamless integration and deployment
      Integrates with your existing data security system through a cloud-native architecture, enabling intelligent classification and grading without modifying your infrastructure.



    This capability shifts sensitive data detection from a rule-driven to an AI-driven approach, providing core support for building an accurate, efficient, and scalable data security system.

    Procedure

    Classification and Grading Enabled

    DSC provides a bonus AI detection quota based on your purchased Data Identification quota:

    • For every 10,000 tables purchased for Data Identification - Database Table Quantity, you receive a bonus of 60,000 AI Text Detection calls.

    • For every 1 TB of storage purchased for Data Identification - Storage Identification Capacity, you receive a bonus of 4,000 AI Text Detection calls and 4,000 AI Image Detection calls.

    If you have purchased DSC and enabled classification and grading for your data assets, the complimentary AI detection capabilities are enabled automatically.

    If data classification and grading is not enabled or you have not purchased Data Security Center

    If you have not purchased Data Security Center, purchase it from the Data Security Center purchase page. If you purchase the Value-added Service Only edition, you must separately enable the Data Identification feature. The Premium and Enterprise editions include this feature by default. For more information, see Purchase Data Security Center.

    DSC provides a bonus AI detection quota based on your purchased Data Identification quota:

    • For every 10,000 tables purchased for Data Identification - Database Table Quantity, you receive a bonus of 60,000 AI Text Detection calls.

    • For every 1 TB of storage purchased for Data Identification - Storage Identification Capacity, you receive a bonus of 4,000 AI Text Detection calls and 4,000 AI Image Detection calls.

    • One-click AI data detection: Go to the Overview page of the Data Security Center console. In the One-click AI Data Detection dialog box that appears, follow the on-screen instructions to enable the classification and grading feature for all your cloud assets with one click.

    • Enable AI-powered data detection for a specific asset: Go to the Data Security Center console. In the navigation pane on the left, choose Asset Center. Then, click Asset synchronization and find the target asset. In the Classification and Grading column for the asset, click image to enable the feature. For more information, see Asset Center (New Version).

    After classification and grading is enabled, the complimentary AI detection capabilities are enabled automatically. In the left-side navigation pane, choose Classification and Grading > Asset Insight to view the results.

    Quota consumption rules and pricing

    • Offline scan scenarios:

      • Scanning 1 TB of text files consumes approximately 100,000 text detection calls.

      • Scanning 10,000 data tables consumes approximately 3,000,000 text detection calls.

      • Scanning 1 TB of images consumes approximately 1,000,000 image detection calls.

    • API call scenarios:

      • Text detection: Each text input that contains at least one piece of sensitive information consumes one call. The text for a single input cannot exceed 2,000 characters. Text that exceeds the limit is not scanned.

      • Image detection: Each scanned image consumes one call. A single image cannot exceed 10 MB. Images that exceed the limit are not scanned.

    Feature

    Pricing

    AI Text Detection

    Number of calls: USD 3/10,000 calls/month

    AI Image Detection

    Number of calls: USD 6/10,000 calls/month

    Handling AI detection quota depletion

    When your AI detection quota is depleted:

    • Text detection: All Identification Models stop invoking the AI LLM, reducing detection accuracy by 15% to 30%.

    • Image detection: DSC cannot detect images.

    The DSC console prompts you to upgrade. Follow the on-screen instructions or click Upgrade on the Overview page. In the AI Data Security Detection section of the upgrade page, select the required number of AI Text Detection and AI Image Detection calls.

    Note

    To conserve quota, you can manually control the AI LLM invocation status for Identification Models or OSS Identification Tasks.

    • Identification Models: Go to Classification and Grading > Config. On the Identification Models tab, find the target detection model and click the switch icon in the AI Model Invocation column to disable the feature. We recommend that you do not perform this operation unless necessary. For more information, see View and configure detection templates.

    • OSS Identification Tasks: Go to Classification and Grading > Tasks. On the Identification Tasks tab, select OSS and then click Create. On the Create page, turn off the AI-Powered Image Detection switch. For more information, see Scan for sensitive data using a detection task.
