Overview

Sensitive Data Definition

Sensitive data is usually used by others without the consent of individuals or companies. The interests of individuals or companies might be seriously compromised.

According to GB/T 35273-2020 Information Security Technology — Personal Information Security Specification, sensitive personal data includes:

• Personal property information (deposit, credit, and banking transactions)
• Personal health state and physiological information (physical examination information and medical records)
• Personal biometric information (fingerprint and facial features)
• Personal identity information (ID card, social security card, and driving license)
• Other information (religious belief and precise location)

Sensitive Data Protection Methods

• Sensitive data identification and label adding

  Classify and grade data to facilitate security management of different granularities and levels.

• Data leakage detection and prevention

  If sensitive data is frequently accessed, a risk alarm is reported immediately.

• Static data masking and data watermarking

  Sensitive data with a specific security level can be masked or watermarked when being provided to external systems.

• Personal information compliance

  Accurately distinguish and protect personal data to avoid compliance issues.

• General data protection regulation (GDPR) compliance

  Comply with GDPR requirements on detecting and protecting sensitive data, and audit the use of sensitive data.

• Data security compliance check

  Based on the analysis of sensitive data, develop data security compliance management regulations to help enterprises build and improve their information security compliance management systems.

Sensitive Data Identification Process

Figure 1 shows the sensitive data identification process.

Figure 1 Sensitive data identification process

1. Create data security levels.

   Before performing any operations on data, create security levels for the data to specify the scope of confidential information.

2. Create data classifications.

   If data security levels cannot meet the data classification requirements in the case of a large amount of data, you can create data classifications for data of different values to better manage and measure your data.

3. Create identification rules.

   Define sensitive data identification standards.

4. Create identification rule groups.

   Define sensitive data identification rules and rule groups for the purpose of effectively identifying sensitive data in a database.

5. Discover sensitive data.

   Create and run a sensitive data identification task.

6. View sensitive data distribution.

   View the sensitive data identified by the sensitive data identification task.
