1. Brief description
Desensitization refers to protecting the security of sensitive information during storage and use by partially or completely hiding sensitive data. Common application scenarios include logging, interface return, report display, data analysis, etc., especially in systems involving user privacy, payment information and enterprise data.
2. The significance of data desensitization
Protect privacy
Prevent sensitive data leakage, such as ID number, bank card number, mobile phone number, etc.Comply with compliance requirements
Comply with regulations such as the Personal Information Protection Law (PIPL) and the General Data Protection Regulations (GDPR).Reduce data risks
Even if the data is leaked during transmission and use, sensitive information will not be exposed.
Common desensitization scenarios:
Desensitization of mobile phone number
Example: 13912345678 -> 139****5678Identification number
Example: 123456789012345678 -> 123456******5678Email desensitization
Example: example@ -> ex****@Desensitization of bank card number
Example: 6222020400112568888 -> 6222 **** **** 8888
3. Examples of data desensitization
3.1 Custom desensitization implementation
Add the desensitization tool class DesensitizationUtils:
public class DesensitizationUtils {
// Desensitization of mobile phone number public static String maskPhone(String phone) {
if (phone == null || () != 11) {
return phone;
}
return (0, 3) + "****" + (7);
}
// Identity card number desensitized public static String maskIdCard(String idCard) {
if (idCard == null || () < 15) {
return idCard;
}
return (0, 6) + "********" + (() - 4);
}
// Email desensitization public static String maskEmail(String email) {
if (email == null || !("@")) {
return email;
}
int atIndex = ("@");
if (atIndex <= 1) {
return email;
}
return (0, 2) + "****" + (atIndex);
}
// Desensitization of bank card number public static String maskBankCard(String bankCard) {
if (bankCard == null || () < 16) {
return bankCard;
}
return (0, 4) + " **** **** " + (() - 4);
}
}
Examples of desensitization:
public class Main {
public static void main(String[] args) {
String phone = "13912345678";
String idCard = "123456789012345678";
String email = "example@";
String bankCard = "6222020400112568888";
("Desensitized cell phone number: " + (phone));
("Desensitized ID number: " + (idCard));
("Desensitized Email: " + (email));
("Desensitized bank card number: " + (bankCard));
}
}
3.1 Reference Component desensitization implementation
The following is a complete solution to implement data desensitization using the Maven package provided, including Maven dependencies and implementation steps.
It is a library dedicated to data desensitization, supporting a variety of desensitization strategies. The following are the related dependencies:
<!-- data desensitization-->
<dependency>
<groupId></groupId>
<artifactId>desensitization</artifactId>
<version>2.4.3</version>
</dependency>
An annotation-based desensitization mechanism is provided, first adding annotations to the fields that need to be desensitized:
package ;
import .*;
public class User {
@ChineseNameSensitive
private String name;
@IdCardNumberSensitive
private String idCard;
@PhoneNumberSensitive
private String phone;
@EmailSensitive
private String email;
@PasswordSensitive
private String password;
// Getters and Setters
public String getName() {
return name;
}
public void setName(String name) {
= name;
}
public String getIdCard() {
return idCard;
}
public void setIdCard(String idCard) {
= idCard;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
= phone;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
= email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
= password;
}
}
Use the Sensitive tool class in the library to desensitize:
public class DesensitizationController {
public static void main(String[] args) {
User user = new User();
("admin@");
("89144552522");
("admin");
("13845988146");
("6222020400112568888");
user = (user);
("Desensitized User Information: " + (user));
}
}
Output example:
User information after desensitization: {"email":"a****@","idCard":"622202*********8888","name":"a****","password":"***********","phone":"138****8146"}
It provides flexible desensitization based on annotation and processor, supports sensitive data protection in multiple scenarios, and is especially suitable for Java projects that require dynamic desensitization.
4. Summary
Data desensitization is a key technology for protecting sensitive information. It can not only achieve desensitization in common scenarios through simple tools, but also use annotation and reflection to achieve flexible automatic desensitization. In actual development, it is recommended to choose an appropriate desensitization solution based on business needs and performance requirements to ensure the security of sensitive information.
Application scenarios:
- User privacy display: the user's mobile phone number or name in the order information.
- Logging: Hide user-sensitive data when recording error messages.
- Data analysis: Avoid leakage of sensitive information when exporting or sharing data.
Through a reasonable desensitization strategy, the risk of data breaches can be effectively reduced while meeting the legal requirements of privacy protection.
