3 min readMay 22, 2024
In today’s digital age, data security is paramount. With increasing regulations and data breaches, it’s crucial to protect sensitive information, especially when dealing with user data. Data masking is a powerful technique to safeguard this information. This comprehensive guide will walk you through implementing data masking in a Spring Boot application with practical examples.
What is Data Masking?
Data masking is the process of hiding original data with modified content (characters or other data). The main purpose is to protect sensitive data while ensuring it is still usable for various purposes like testing and analytics. Masking replaces actual data with fictional data that maintains the format of the original data.
Why Use Data Masking?
- Security: Prevents unauthorized access to sensitive data.
- Compliance: Helps in adhering to data privacy regulations such as GDPR, HIPAA, etc.
- Testing and Development: Provides realistic data without exposing sensitive information.
