Difference between Tokenization and Encryption

Tokenization is vital in data security to obscure information that should not be viewed and encryption is a significant strategy in security used to secure delicate data including credit card numbers, PII, and other sensitive information. The two techniques change the form of the information stored in a dataset to ensure that only authorized persons can access it. But depending on their architecture and methods, they are vastly different and serve different purposes. Tokenization substitutes the sensitive data with a non-sensitive token and encryption is the process where the data is encoded in a way that cannot be read in the absence of an extraction key. It is thus important for anyone facing the question of how to secure data in various scenarios to understand the difference between tokenization and encryption.

What is Tokenization?

Tokenization, as the name suggests, is a replacement technique that replaces sensitive data with randomly generated code that is known as a token. Here, token generally serves as references or placeholders for original data. It simply preserves the feel and format of data and also preserves the privacy of the data subject. It is often used for credit card processing for added security.
Example :

Advantages of Tokenization

• Reduced Risk of Data Breaches: The fact is that tokens are devoid of any meaning and the actual data cannot be reconstructed from tokens which makes the process of tokenization as safe as possible to minimize the data leakage.
• Compliance: Tokenization makes it easier for organization to implement data protection regulations such as the PCI DSS as it does not store a lot of information in the system.
• Simplified Data Management: This is a less complex solution, by storing tokens instead of data, thus also the compliance audits can be managed by having less scope.
• Performance: Tokenization is generally less of a burden on the system than encryption because tokenization does not involve computations.

Disadvantages of Tokenization

• Dependency on Token Vault: Despite these benefits, tokenized data rely on the security of the token vault which may act as a major weakness.
• Limited Scope: Tokenization is best suited for selective form of data wherein payment information, for instance, may fit this format but tokenization cannot be implemented in different types of sensitive data.
• Implementation Complexity: To establish and sustain the tokenization system, generally, it may involve many challenges as well as might be time consuming.

What is Encryption?

Encryption, as name suggests, is a process that combines mathematical algorithm and some other secret information to transform or convert data in a way that is essentially impossible to reverse without appropriate key. It simply uses algorithms to convert plain text information into non-readable form known as cipher text. It can also be reversed so that authorized person can view and use raw and sensitive data. It is considered most effective way to achieve data security.
Example :

Advantages of Encryption

• Strong Security: Encryption offers great protection to the most delicate information. For instance, even if the information that is being transmitted is intercepted, it would be most useless to the interceptor because the data cannot be read without the key.
• Versatility: Encryption may enact on the kinds of data and in different setting or circumstances such as in storage, communication, and files.
• Compliance: This is due to the fact that encryption assists organizations to adhere to the set legal standards since it forms part of the security measures that seek to eliminate exposure of the data to unauthorized individuals.
• Data Integrity: Security begins with the process of transfer where encrypting ensures that data remains clean and is only revealed to the intended person of authority, and in the process the data is also kept confidential and has not been changed or corrupted.

Disadvantages of Encryption

• Key Management: One issue with encrypted data is the issue of key management, which is at the same time a very sensitive and often very complicated matter.
• Performance Overhead: Encryption can have drawback of performance penalty because encryption is computationally expensive to process in that it requires time to encrypt the data as well as decrypt it.
• Potential for Data Loss: Some of the risk or consequences which may occur in the case of database include the following, If the encryption key is lost or compromised, the encrypted data may become permanently inaccessible.

Difference Between Tokenization and Encryption

Conclusion

While tokenization and encryption are both crucial when managing and protecting sensitive data, the two approaches have certain advantages and disadvantages and must be used for different purposes. Tokenization is well suited for safeguarding some kind of data, such as payments info, by replacing it with low impact tokens. Encryption, on the other hand, has broader purposes of protecting information by placing it in a coded system which can only be accessed with a decryption key. It is important to understand that in some cases, it is necessary to select tokenization and in others encryption predominantly based on the peculiarities of the information and the purpose of its protection.
