Data Tokenization: The Introduction

Companies that process large amounts of sensitive data are constantly looking for ways to ensure their information is safe. While many companies choose to use encryption for this purpose, tokenization is a more efficient and effective alternative.  So, in recent years, data tokenization has become increasingly popular as a means of securing digital payments. In short, tokenization is referred to as an advanced security technology that replaces sensitive information with random strings of characters known as tokens, making it impossible for the data to be stolen or misused.

This article will explain the tokenization glossary, which may come as difficult for beginners, and will describe the ways it is used to secure payment systems. It will also provide an overview of the benefits that come with using tokenization in comparison to traditional methods of data protection. So, let’s start from the very basics.

What is tokenization?

Tokenization is aimed at replacing sensitive data such as credit card numbers, bank account details, and social security numbers with a unique surrogate. In fact, it is an advanced security technology that replaces information with random strings of characters known as tokens, making it impossible for the data to be sto

Indeed, tokenization is a very effective way to protect sensitive data from hacking, but it’s not just limited to payment systems. It can be used as a security measure for almost any type of data that needs protecting, including personal information and user credentials.

How does tokenization work?

Unique tokens used to replace sensitive information can literally be stored, transmitted, and processed just like the original data. But the reason tokens are a good way to protect sensitive data is that they can’t be used by attackers to gain access to sensitive information. They simply contain a reference or pointer to the original data, which is stored in an encrypted format, but nothing more. This means that even if an attacker gains access to the tokens, they can’t be used to get access to sensitive data.

Types of Tokenization

There are different types of tokenization available, depending on the data types and the level of security required.

The first one is replacement tokenization. This classic approach replaces sensitive data with non-sensitive data. An example is the replacement of Social Security Numbers (SSN) with a random string of numbers, as we have just described above. And, as we have stated, it can’t be used to reconstruct the original data.

Another type that replaces data and, in fact, is a form of replacement tokenization is the Single-Use Token. This type of tokenization involves the use of a single token that is generated and used to represent a larger piece of data. This process is referred to as “token for data” or “one-to-one” tokenization. One special advantage of this process is that it can be used to replace multiple pieces of data with a single token. This makes the information easier to manage and use while also improving security. Another advantage of single-use tokens is that they are used in place of the original data and can be used as a stand-in while accessing the data. This process allows users to access their data quickly without having to wait until the larger piece of data is retrieved.

Split tokenization splits sensitive data into multiple tokens, each containing a portion of the original data. This is used when different parts of the original data are sensitive in different ways. For example, a credit card number may be split into three tokens: the first four digits, the last four digits, and the security code. The first four digits are sensitive to a single customer. The last four digits are also sensitive to that customer, but they will not be stored on the same servers as the first four digits. The security code is only sensitive in a single data store.

The Benefits of Tokenization

Tokenization is a powerful tool that can be used to improve the security of sensitive data, streamline processes, and create new opportunities for organizations. It can help businesses reduce fraud, increase customer loyalty, and create a more streamlined experience for customers when making purchases online or in-store.

Tokenization eliminates the need for storing sensitive data since only the tokens are stored in the system – not the actual payment information itself. Tokenization is also really easy to implement. It doesn’t require new hardware or software and can be done in just a few minutes.

Tokenization can be used to protect any kind of data, and it’s especially useful for protecting credit card information. So, there are many different applications for tokenization. It can be used in any business that handles sensitive data or accepts credit cards from customers. In addition, tokenization’s aim may be:

Protecting unstructured data on computers and servers;

Protecting sensitive data stored on laptops or mobile devices;

Protecting sensitive data stored on backup tapes and discs;

Protecting databases that contain sensitive information; Etc.

Anyway, the main reason people turn to tokenization is security and certainty. In today’s world, these things are of the greatest value. And regarding security, there is one more issue we have to discuss.

PCI DSS Compliance

The Payment Card Industry Data Security Standard (PCI DSS) is an important set of security standards adopted by companies to ensure the secure processing, transmission, and storage of payment card data.

In fact, PCI DSS compliance is a must for any company that processes, stores and/or transmits payment card information. Failure to comply with the standard can result in hefty fines as well as potential damage to a company’s reputation.

This required Data Security compliance can be achieved by implementing the security controls listed in the PCI DSS standard and meeting specific requirements of each of the 12 DSS objectives.

The stringent requirements of the PCI DSS are designed to protect merchants, consumers, banks, and payment processors from malicious activity such as identity theft or data breaches. Companies must design their systems with these standards in mind in order to remain compliant; this includes implementing measures such as encryption technologies, regular scanning for vulnerabilities, and proper access control procedures.

The PCI DSS requires that merchants protect cardholder data from any unauthorized access. It also requires that companies develop and maintain a system for sharing information about attempted or successful security breaches with their payment processor and their card issuer.

The data exchange standardization requirements of the PCI DSS are intended to allow merchants to receive alerts via a single channel in the event of a breach. So, in order for this to work, merchants must ensure that their systems can communicate with all relevant parties and respond appropriately.

Moreover, the Payment Card Industry Data Security Standard outlines specific requirements for organizations using tokenization to protect their customers’ information.

The PCI DSS includes the following requirements for tokenization:

Tokenized environments must protect cardholder data at rest and during transmission with strong cryptography. Tokenization systems must implement controls to prevent unauthorized parties from accessing cardholder data. However, there are other standards that have been developed to help organizations understand the importance of tokenization and how it should be implemented.

Having briefly discussed tokenization, its benefits, and the PCI DSS requirements, we wish you all the best on your way to increasing security and assuring your customers of your reliability.
