Editing Tokenization (data security) (section)

== Restrictions on token use ==
Not all organizational data can be tokenized, and needs to be examined and filtered.

When databases are utilized on a large scale, they expand exponentially, causing the search process to take longer, restricting system performance, and increasing backup processes. A database that links sensitive information to tokens is called a vault. With the addition of new data, the vault's maintenance workload increases significantly.

For ensuring database consistency, token databases need to be continuously synchronized.

Apart from that, secure communication channels must be built between sensitive data and the vault so that data is not compromised on the way to or from storage.<ref name=":0" />
