What is Tokenization? And what is the difference between Tokenization and Masking?
Tokenization is a technique that replaces personal information that might directly reveal identity of an individual with a unique identifier from a secure look up table and is designed to be reversible. It is the use of a token such as a random string of characters to replace other data and often used by organizations that process credit card data. In this arrangement, a third party holds the mapping of the token and the credit card number or the lookup table, but the organization will not maintain the credit card data.
Whereas other techniques such as masking and hashing techniques replace the data with values that cannot be reversed back to the original data if performed properly.
