Desensitization and Encryption (De-identification: SDI)

I. Target Users

Users who deploy AskTable locally and use cloud computing power (large models).

II. Function Overview

When using AI technology for enterprise data retrieval and analysis, privacy and security become key concerns for enterprises.

To address this, AskTable introduces the SDI (Secure De-Identification Inference) desensitization feature to encrypt and desensitize sensitive information locally.

This function supports local desensitization of sensitive fields (such as name, phone number, ID number, email, bank card number, etc.), ensuring that data has completed the removal of identifiers before being sent to the cloud AI model for inference, avoiding the leakage of sensitive information.

SDI achieves "data stays local, thinking happens in the cloud," ensuring data security while fully utilizing the intelligent capabilities of top-tier cloud large models.

III. Supported Types of Desensitized Fields

AskTable currently supports the following types of fields for desensitization:

TypeExampleConfiguration Item Name
NameZhang San, Li SiPerson's Name
Phone Number13800001234Telephone
ID Number110101199001011234ID Number
Email Addressuser@example.comEmail

If you have any other specific requirements, please contact us.

IV. Configuration Method and Usage Process

AskTable supports setting desensitization strategies at the level of data source fields, enabling desensitization functionality through system configuration without requiring additional development or complex deployment.

Configuration Steps:

  1. Enter the data source field management interface;
  2. Select the type of sensitive information (e.g., "Person's Name," "Telephone") for the corresponding field in the "Desensitization Encryption" column;
  3. After saving, the field will automatically be desensitized in the query results.

As shown in the image below, you can configure the corresponding desensitization types for the salesperson_name and phone fields:

V. Common Questions

1. Will desensitization affect analytical accuracy?

In most cases, it will not. AskTable still uses real field names and structures when generating SQL queries, only performing desensitization on sensitive fields during the query result stage, which does not affect the semantic meaning or result accuracy of the analysis. However, in rare cases, due to noise introduced during the reconstruction process, the large model may misunderstand and exhibit phenomena such as "unable to answer."

2. Will enabling SDI bring performance impacts?

Yes, there will be some performance overhead. For queries involving desensitized fields, processing time will increase by approximately 2-3 seconds on average.

3. Does the SaaS version need to enable the SDI function?

It is not recommended. Since the SaaS version runs in a cloud environment and data is already transmitted to the AskTable backend for processing, enabling SDI has limited significance and may add extra latency.

4. Will enabling SDI impact business users?

No impact. SDI processing occurs internally within the system, and business users are unaware of it; it will not affect their experience of asking questions, querying, or viewing results.

VI. Summary

The SDI (de-identification) function is an important capability for AskTable to balance data security and intelligent analysis. By desensitizing sensitive fields locally and then sending the processed data to the cloud model for inference, SDI achieves a new mode of "data stays local, intelligence relies on the cloud."

Compared to deploying large models locally, the cost of using cloud computing power is only about 1% of the former. The introduction of SDI allows enterprises to access the latest AI capabilities at a low cost and securely, significantly reducing the entry barrier.

For industries with high data security requirements and sensitivity to costs, such as government and enterprise, healthcare, SDI provides a solution that balances privacy protection and intelligent analysis, helping accelerate the practical application of AI technologies in real business scenarios and promote the popularization and development of enterprise intelligent transformation.

Through SDI, AskTable not only ensures data security but also provides users with high-cost-performance intelligent analysis capabilities, truly realizing the AI value loop of "secure and trustworthy, cost controllable, usable results."
