Network security incidents occur now and then, mostly caused by data leakage. Data security has aroused widespread concern, and the community keeps working hard on approaches to simplify data security, especially in sensitive data protection.

Sensitive data includes but is not limited to personally identifiable information (PII) like names, ID numbers, passport numbers, driver’s license numbers, contact information like addresses, phone numbers, account credentials like usernames, passwords, PINs, and financial information like credit card numbers, bank account numbers, bank codes.

There are many aspects to properly protecting data. In the next section, I will cover data protection methods in Java, including encryption, anonymization, hashing, and access control.

Data Protection in Java

The native implementations to secure sensitive data are similar across different language environments. So, let me take Java as an example and walk you through some of these aspects.
