How Does Tokenization Work?

Tokenization is a security technique that replaces sensitive information with unique placeholder values called tokens.

By tokenizing your sensitive data, you can protect them from unauthorized access and lessen the impact of data breaches. Tokenization also lets you scale back on security measures in other areas of the system.

Sensitive data is sent to a ???????????? ??????? when it enters the system. There, a unique token is generated, and both the sensitive data and the token are kept in a secure database known as a ????? ?????.

For extra protection, the sensitive data is generally encrypted within the secure data storage. The ????? ?? ???? ???? ?? ????? ?? ??? ????????? ???? ?????? ??? ?????? ??? ?????-????? ????????????.

When an authorized service requires sensitive data, it sends a request to the tokenization service that contains the token. The tokenization service validates that the requester has all the required permissions. If it does, it uses the token to get the sensitive data from the token vault and returns it to the authorized service.

Tokenization is useful for more than just protecting sensitive data. It also helps simplify the rest of the system, because you don't need to worry about additional security measures in components that handle a token instead of sensitive data.
