This blog delves into the similarities and differences between tokenization and encryption, exploring their effectiveness in protecting data and their respective use cases in modern data security strategies. So, continue reading and make the right choice between the two.<\/p>\n\n\n\n
What is Tokenization?<\/h2>\n\n\n\n![\"Tokenization\"](\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2024\/05\/tokenization.png\")
<\/figure>\n\n\n\nTokenization is substituting sensitive data elements, such as a bank account number or credit card number, with a non-sensitive equivalent, referred to as a token. The token is a random data string with no specific meaning or use. Tokenized data is imponderable and irrevocable, meaning the token and its source number have a one-way relation.<\/p>\n\n\n\n
One might apply no keys or mathematical operations to the token to obtain the original data. Instead, tokenization uses a reference database, a token vault that maintains the relationship between the token and the sensitive value. The confidential data in the vault is then protected, typically via encryption.<\/p>\n\n\n\n

Although tokens are contextual unorthodox words, they have many definitive features of sensitive data, such as spam or format, making it simple to incorporate them into regular business operations.<\/p>\n\n\n\n
Real confidential data is retained in a peripheral place, such as a network or data storage system, distinct from the enterprise\u2019s indoor infrastructure. In machine learning, tokenization is used in feature extraction, transforming textual data into a system that the model can train.<\/p>\n\n\n\n
In addition to natural language processing, tokenization is introduced in data privacy and blockchain security to transform private information into token forms and reduce the risk of exposure to private data while transacting or storing it.<\/p>\n\n\n\n
Tokenization Pros:<\/h3>\n\n\n\n\n- Token\u2019s characters are random and effectively meaningless and can\u2019t be stolen.<\/li>\n\n\n\n
- The original sensitive data never has to leave the secure systems of the organization responsible for it.<\/li>\n\n\n\n
- Tokenization makes PCI compliance a snap and more affordable because it reduces the amount of your technology infrastructure that has to be fully PCI DSS compliant<\/a>.<\/li>\n<\/ul>\n\n\n\n
Cons:<\/h3>\n\n\n\n\n- Tokenization can be difficult to scale securely while preserving performance.<\/li>\n\n\n\n
- You cannot freely exchange data; the only way to read it is by accessing the token vault.<\/li>\n<\/ul>\n\n\n\n
How does Data Tokenization Work?<\/h3>\n\n\n\n![\"How](\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2024\/05\/how-tokenization-works.jpg\")
<\/figure>\n\n\n\nThe most popular measure of protecting personal and financial information from criminals is tokenization. <\/p>\n\n\n\n
Let\u2019s consider banking<\/strong>, where tokenization secures cardholder data. The systems storing the token do not share the original credit card tokenization system, which replaces the token with the corresponding primary account number (PAN) and forwards the PAN to the processor for authorization.<\/p>\n\n\n\nThe system cannot depart \u2013 the token is retained, and the tokenization framework determines and replaces the corresponding PAN for inquiries to the payment processors. Also, the PAN record is overlooked rather than intensified \u2013 solely the token is saved under the system.<\/p>\n\n\n\n
Organizations must secure a payment gateway for tokenization to store sensitive data efficiently. Its merchant services allow direct payment through credit cards and shipping. The gateway saves credit card numbers securely and responds exactly with the random token.<\/p>\n\n\n\n
What is Encryption?<\/h2>\n\n\n\n![\"Encryption\"](\"https:\/\/certera.com\/blog\/wp-content\/uploads\/2024\/05\/encryption.png\")
<\/figure>\n\n\n\nEncryption<\/a> transforms sensitive data into a disguised, unreadable form known as ciphertext using an algorithm. This text, in turn, can only be decoded by another algorithm, but this time, the original algorithm and the encryption key were used.<\/p>\n\n\n\nSuppose the URL has a lock icon before it. In that case, the page’s information is encrypted using Secure Sockets Layer (SSL)<\/a>, which encrypts data wherever it’s transmitted between a website and browser or between servers.<\/p>\n\n\n\nRecommended:<\/strong> Asymmetric vs. Symmetric Encryption: What are Differences?<\/a><\/p>\n\n\n\nFor instance, when customers enter their card details at checkout, SSL ensures the data is scrambled during transmission. It can only be decrypted when it reaches your online store’s web server, where your payment processor uses it to finish the transaction, and they are captured for future payments.<\/p>\n\n\n\n
However, because it is based on an algorithm, encryption can be broken by a hacker. If a criminal managed to steal your systems and capture the encryption key, they could reverse the data to its readable format. This scenario indicates that it is pretty insecure compared to tokenized data.<\/p>\n\n\n\n
Encryption Pros:<\/h3>\n\n\n\n\n- Encryption is easy to scale as the volume of your data continues to grow.<\/li>\n\n\n\n
- It is easy to share encrypted data with a 3rd party, provided they have the proper encryption key.<\/li>\n<\/ul>\n\n\n\n
Cons:<\/h3>\n\n\n\n\n- Encrypted data becomes readable by hackers if they get their hands on the encryption key.<\/li>\n\n\n\n
- Although it is encrypted, the original plaintext data does have to leave the organization to complete the transaction, which makes it more vulnerable.<\/li>\n\n\n\n
- You cannot reduce the scope or cost of meeting your compliance obligations because your whole technology infrastructure must be fully PCI-compliant.<\/li>\n<\/ul>\n\n\n\n

<\/figure>\n\n\n\nEncryption entails converting \u2018plaintext\u2019 into \u2018ciphertext.\u2019 This is accomplished through encryption algorithms and mathematical models based on cryptography. Decrypting the text back to plaintext necessitates applying a decryption key, which is a fair number of digits or a password also created to the order of an algorithm.<\/p>\n\n\n\n
Recommended:<\/strong> What is a Cipher? Types of Ciphers in Cryptography<\/a><\/p>\n\n\n\nIn practice, secure encryption has such an enormous number of cryptographic keys that an unauthorized person cannot guess which key to use. Nor can a computer easily calculate the correct string of digits by trial and error, using every potential combination.<\/p>\n\n\n\n
An early example of simple cryptographic substitution <\/strong>is the \u201cCaesar cipher,\u201d named after the Roman emperor Julius Caesar, who used this encryption in his private notebooks. In the Caesar cipher, each letter in the plaintext is replaced by another letter, a fixed number of positions down the alphabet.<\/p>\n\n\n\nAlso Read:<\/strong> What is a Cipher?
