Encryption is the classic means of protecting sensitive data by transforming information with an encryption key, which can then only be read with the correct decryption key. Unlike tokenization, when encrypted data is transferred, the actual sensitive information is still transmitted, leaving it vulnerable to being intercepted and stolen. And all encrypted files, no matter how sophisticated, are eventually decryptable. Tokens, however, are functionally useless if copied or stolen. They act more like unique keys to get access to data,…
