What is a Token?
Tokens are non-minable digital assets that exist as blockchain registry records. There are several applications for tokens, which come in a variety of formats. They can be used to encrypt data or act as currency, for instance.
Typically, blockchains like the Ethereum blockchain and BNB Chain are used to issue tokens. Some of the popular token specifications include ERC-20, ERC-721, ERC-1155, and BEP-20. Tokens are exchangeable units of value created on top of a blockchain, as opposed to native to the underlying blockchain cryptocurrency coinage like ether or bitcoin.
In a process known as tokenization of real-world assets (RWAs), some tokens might be exchangeable for off-chain commodities like gold and real estate.

What Is Data Tokenization?
Today, data is one of the most valuable resources businesses can use, thus keeping it secure is essential. Data leaks and breaches have increased in frequency while data security and governance are frequently listed as data leaders’ biggest issues.
Organizations are increasingly using data tokenization, a technique that replaces sensitive data, like a customer’s social security number or bank account number, with a token, a randomly generated data string, to reduce threats to data privacy.
It’s important to note that tokens lack any intrinsic significance and cannot be decoded to expose the original data they represent. When a token is de-tokenized, the original data it represents can only be accessed by the system that generated the token.
Sensitive data, such as credit card numbers or medical records, are transformed into tokens that may be transferred, stored, and used without the original data being exposed. This process is known as data tokenization.
These tokens are often one-of-a-kind, immutable, and blockchain-verifiable to improve data security, privacy, and compliance. It is possible, for instance, to tokenize a credit card number into an arbitrary string of digits that can be used for payment verification without disclosing the real card number.
Social media accounts are also subject to data tokenization. Users have the option of tokenizing their online identity to move across social media platforms without losing control of their personal information.
Tenization of data is an idea that has been around for a while. Although it has the potential to be utilized in many industries, it is frequently used in the financial sector to secure payment information.
Why Is Data Tokenization Important?
According to a poll of data professionals, 75% of organizations gather and keep sensitive data that they either already use or plan to use. By replacing it with tokens that stand in for the actual data, tokenization is a method for securing that data.
For instance, a random sequence of numbers, letters, or symbols could be used in place of a customer’s 16-digit credit card number. Any online payments would be infinitely more secure as a result of this tokenization procedure, which would make it impossible for a potential attacker to use the customer’s credit card details.
Businesses that utilize tokenization are still able to use their data as they have in the past, with the added benefit of being protected from the risks that come with retaining sensitive data. This reduces their vulnerability to data breaches and puts them in a much better position to comply with a wide range of constantly changing data compliance laws and regulations.
Data tokenization helps businesses find the ideal balance between maximizing the value of their data and maintaining its security. It’s a successful method of obtaining crucial information without expanding the surface area for risk in highly regulated sectors like healthcare and financial services.
Additionally, by providing customers with the assurance that their personally identifiable information (PII) won’t end up in the wrong hands, data tokenization can assist gain their trust.
What’s the Difference Between Tokenization and Encryption?
It’s common to use the terms tokenization and encryption interchangeably. Both of these methods of data obfuscation assist protect data while it is in motion and at rest. It’s critical to comprehend the variations between these methods of data privacy despite their striking similarities.
Tokenization substitutes data with a token value created at random, whereas encryption uses an encryption technique and key to transform plaintext data into ciphertext, which cannot be read.
Depending on the requirements of your organization, you must choose the best approach. For organizations who want to maintain compliance and reduce their PCI DSS requirements, tokenization, for instance, is fantastic. While encryption is perfect for sharing private data with individuals who possess an encryption key.
Encryption is a popular technique for preventing data breaches or leaks as remote work has increased dramatically in recent years and data is increasingly accessed from many different locations.
In order to keep information secure while in transit, ATMs frequently employ encryption technologies. Because of this, it’s a fantastic option for businesses that need to encrypt massive amounts of data.
How Does Data Tokenization Work?
Imagine a user who wishes to change the social networking site they use. The user would have to create a new account and submit all of their personal information from scratch on standard Web 2.0 social media services. Additionally, it’s possible that relationships and post history from the previous platform won’t transfer to the new one.
Users can link their current digital identity to the new platform using data tokenization to transfer their personal data automatically. The user must have a digital wallet like Metamask with a wallet address that represents their identity on-chain in order to accomplish this.
The wallet must then be linked to the new social networking platform by the user. Due to the fact that Metamask houses the user’s digital identity and data on the blockchain, personal history, connections, and assets are instantly synchronized to the new platform.
As a result, the user won’t lose any tokens, NFTs, or previous transactions they accumulated on the previous platform. As a result, the user no longer feels constrained to a specific platform and has full control over which platform to migrate to.
What are the Advantages of Data Tokenization?
1. Greater Data Security
Data security is improved by data tokenization. By replacing sensitive data with tokens, data tokenization reduces the risk of data breaches, identity theft, fraud, and other assaults. Tokens are linked to the original data via a secure mapping mechanism so that even if they are stolen or leaked, the original data is still secure.
2. Adherence To Regulations
Strict data protection laws apply to many businesses. Tokenization can assist businesses in adhering to these standards by protecting sensitive data and offering a method that can lessen the likelihood of non-compliance. Because tokenized data is viewed as non-sensitive, data administration may be made simpler and security audits may be carried out more easily.
3. Safe Data Sharing
Tokenization might make it possible for partners, vendors, and departments to share data securely by limiting access to the tokens and masking sensitive information. Tokenization can grow successfully to suit the expanding needs of organizations while minimizing the cost of implementing data security measures.
4. Increased Transparency
Blockchain technology provides a transparent and immutable record of transactions, making it easier to track the ownership and transfer of assets. By doing so, fraud may be decreased and market confidence may rise.
What are the Disadvantages of Data Tokenization?
1. Decreased Data Integrity
Data quality and accuracy may be impacted by tokenization since some information may be lost or altered throughout the tokenization process. For instance, if a user’s location is made into a token, it can have a detrimental effect on their ability to view location-based relevant content.
2. Interoperability of Data
Data tokenization may make it more difficult for various systems that use or process the data to communicate with one another. Tokenizing a user’s email address, for instance, can stop them from getting alerts from other platforms or services. Depending on the platforms they use, tokenizing a user’s phone number can prevent them from receiving or placing calls or sending texts.
3. Data Management
Tokenizing data could lead to issues with ownership, control, usage, and sharing of the data, which could lead to legal and ethical concerns. For instance, tokenizing a user’s personal data might alter how they give their consent to the collection and use of their data. Tokenizing a user’s social media posts can violate their right to free speech or ownership of their intellectual property.
4. Recovery of Data
If a tokenization system fails, recovering data may be more challenging. The original sensitive data that was stored in the token vault together with the tokenized data can be challenging for organizations to recover.
How Data Tokenization Helps Users Monetize and Control Their Data
Large amounts of user data are daily collected by centralized social media platforms in order to produce targeted advertisements, suggest content, and personalize user experiences. This data is frequently kept in centralized databases, which are susceptible to hacking and compromise as well as being sold without the users’ consent.
Users can tokenize their social media data using data tokenization and sell it to marketers or researchers if they so choose. Users can choose who is allowed to view or share their stuff. They can also design unique rules for their content and profiles.
For instance, they might establish a minimal token balance needed to engage with them or limit access to their material to those who have been authenticated. Users now have complete control over their social network, content, and monetization options like tipping and subscriptions.
Data Masking vs Tokenization
Data masking and tokenization are two methods used to protect sensitive information, but they work in different ways.
Data masking involves hiding sensitive data by replacing it with fictitious or obfuscated data. The goal of data masking is to prevent unauthorized access to sensitive information while still allowing authorized users to access the data they need. For example, credit card numbers can be masked by showing only the last four digits, which are less sensitive and can still be used for identification purposes.
Tokenization, on the other hand, involves replacing sensitive data with a randomly generated string of characters called a token. The original data is stored in a secure location, while the token is used in place of the sensitive data in all other systems. The goal of tokenization is to protect sensitive data from unauthorized access, even if the token is intercepted or stolen. For example, a credit card number can be tokenized so that the token is used for processing transactions, while the original credit card number is stored securely.
Therefore, data masking involves obscuring sensitive data, while tokenization involves replacing sensitive data with a randomly generated token. Both methods are used to protect sensitive information, but they work in different ways and have different use cases.
