In today’s digital age, where data is the new currency, safeguarding sensitive information has become important. Data breaches and cyberattacks are on the rise, making it imperative for organizations to implement robust security measures. One such measure is data tokenization.
You’ve probably used, or if not used, heard of Paypal, Venmo, Google Pay, or Apple Pay. The information these platforms use is quite sensitive. If this information gets leaked, these platforms get hacked. Sure, the chances are minimal, but not zero!
Many users might think, “But my data is encrypted!” However, encryption alone may not be enough to protect against sophisticated cyber threats.
Do you know about Equifax, one of the three largest credit reporting agencies in the US? The Equifax data breach of 2017 is one of the largest data breaches in history. Hackers exploited a vulnerability in Equifax’s systems to steal sensitive data, including Names, Social Security numbers, Birth dates, Addresses, Driver’s license numbers, and, in some cases, credit card numbers. What is the affected number of people? 143 Million, which was more then 40% of the US population at the time.
This is where data Tokenization comes into play.
Data tokenization is a security process that replaces sensitive data with non-sensitive, randomly generated data called tokens. These tokens are essentially placeholders that have no intrinsic value on their own. The original data, often referred to as plaintext, is stored securely in a separate, isolated environment known as a token vault. When sensitive data is needed for processing or analysis, the token is used instead. This ensures that even if the tokenized data is compromised, malicious actors cannot access the underlying sensitive information.
The tokenization process involves the following steps:
Data tokenization offers several critical benefits:
Data tokenization has a wide range of applications across various industries:
While data tokenization is an effective security measure, it is essential to consider the following:
Despite these challenges, the benefits of data tokenization often outweigh the drawbacks, making it a valuable investment for organizations that handle sensitive information.
Data tokenization, data masking, and encryption are all techniques used to protect sensitive information, but they serve different purposes.
Data tokenization replaces sensitive data with non-sensitive, randomly generated data called tokens. This process is often irreversible, meaning the original data cannot be recovered from the token. It’s primarily used to protect sensitive data while allowing authorized users to access and process the tokenized data, for example, for use in analytics or transactions.
Data masking, on the other hand, replaces sensitive data with non-sensitive substitute data that may look similar to the original data. The goal of masking is to protect sensitive data while allowing the use of realistic test or demo data. Unlike tokenization, masking is often reversible, and the original data can be recovered.
Data encryption converts plaintext data into an unreadable format called ciphertext using an algorithm and an encryption key. Only those with the corresponding decryption key can convert the data back to its original form.
Feature | Data Tokenization | Data Masking | Data Encryption |
Purpose | Replace sensitive data with meaningless tokens | Replace sensitive data with non-sensitive substitute data | Convert data into an unreadable format |
Data Transformation | Irreversible replacement | Reversible substitution | Reversible transformation with a key |
Data Accessibility | Requires tokenization system | Accessible for analysis and testing | Requires decryption key for access |
Use Cases | Payment processing, data privacy compliance | Testing, development, data anonymization | Data transmission, storage |
Security Level | High for sensitive data | Moderate, depends on masking complexity | High, depends on encryption algorithm and key management |
Complexity | Moderate, requires token vault | Lower than tokenization | High, requires key management |
Performance Impact | Minimal | Minimal | Can be significant depending on algorithm |
