Masking

Masking data is a method of obfuscation where the original data is replaced with random characters. The masking process itself is not encryption.
Data masking refers to the process of replacing sensitive data elements with non-sensitive ones in order to protect sensitive information and prevent unauthorized access or disclosure.
Masking is a technique used by organizations to protect sensitive data from unauthorized access or disclosure. It replaces the original value with a non-sensitive value that does not disclose any information about the original value, but still preserves the integrity of the information being transmitted.

Masking can be achieved by using any one of the following techniques:

• Encryption
• Hashing
• Tokenization
