What process is used to convert highly sensitive data into a token for security?

Tokenization is the process used to convert highly sensitive data into a token that can be used in place of the sensitive information. In tokenization, the original data (such as credit card numbers or personal identification information) is replaced with a non-sensitive equivalent known as a token. This token is typically generated in such a way that it has no intrinsic value or meaning outside of the specific context where it is used.

The main benefit of tokenization is that it helps protect sensitive data by ensuring that it is not stored or transmitted in its actual form. Instead, only the corresponding tokens are used in various transactions or processes. If a data breach occurs, the stolen tokens would not be valuable for attackers since they cannot be reverse-engineered to retrieve the original sensitive data without access to the secure tokenization system.

This method enhances data security by reducing the amount of sensitive data that is vulnerable to exposure during processing, storage, or transmission. Tokenization is commonly used in industries that need to comply with stringent data protection regulations, such as finance and healthcare.
