Custom Create¶
- Scan Scope:
| Field | Description |
|---|---|
| Data Types | The data type to be scanned; by default, 【LOG】 is selected. |
| Data Filtering | The scope of data to be scanned. |
- Define Matching Rules:
| Field | Description |
|---|---|
| Rule Name | The name of the current data rule. |
| Regular Expression | Used to match the data strings that need to be encrypted. |
| Data Testing | Enter a string of data, click test, and you can verify if it matches the regular expression. Test data will not be saved. |
-
Sensitive Data Processing:
-
Desensitization Fields: Supports three options - all fields, specified fields, and excluded fields; by default, 【specified fields】 is selected;
-
Desensitization Method:
General Encryption: Replaces all matching sensitive data with *;
Partial Encryption: Replaces part of the sensitive data with , allowing some sensitive information to remain visible, e.g., phone number ****1005;
Replacement Encryption: Replaces all matching sensitive data with a specified string, which is irreversible after replacement;
MD5 Encryption: Encrypts any data into a fixed-length string, which is irreversible after replacement.
Characteristics of MD5 Encryption
- Fixed Length: Regardless of the length of the string, the encrypted result is always the same length, i.e., 32 characters;
- High Discreteness: Any change to the original data, even a minor one, leads to a significant difference in the computational result;
- Irreversible Computation: It is impossible to retrieve the original string from the known computational result through reverse computation, but it can still be used for filtering and positioning.
- Add Tags: You can add custom tags to the desensitized data; multiple tags are separated by 【,】.
