Blockchain for Fraud Prevention: How Blockchain Works?

Blockchain technology has been around for a long time, and it is still growing. A lot of people wonder how does blockchain secure data and how blockchain works. Regardless of all its benefits, there are a lot of mixed feelings towards blockchain technology. It doesn’t matter how mixed the reviews of the technology are, the role of blockchain against fraud and the role in the global economic landscape is great. 

The growth of blockchain first came into the limelight with the rise of Bitcoin. If you’re not into cryptocurrency, you should know about the blockchain for fraud prevention. 

How Blockchain Works?

At first glance, blockchain looks complicated, but the core concept of how blockchain works is really simple. A blockchain is a type of database, to completely understand what is blockchain technology, you need to understand what is a database. 

A database is a collection of information that’s stored on a computer system. Any information that’s stored on a database is stored in a table-type manner for easier searching and filtering of data. Now you may wonder, what is the difference between a spreadsheet and a database. 

The major difference between a spreadsheet and a database is that a spreadsheet is made for a single person or a small group of people. These people can store and access limited information. In comparison to that, a database is designed to store much larger amounts of information, that can be quickly accessed, filtered, and changed quickly by any number of users at the same time. 

Huge databases achieve this functionality by using data on servers that are built on powerful computers. While a spreadsheet database can be accessed by several people, it is often owned by businesses. Now that you understand what is a database, we can move on to “how does blockchain secure data”.

How Does Blockchain Secure Data?

One of the major differences between a typical database and a blockchain is the way the data is structured. A blockchain collects information together in groups that are known as blocks, these blocks hold a set of information. Blocks have a specific amount in which information can be stored, when the storage is filled, they are chained to the previously connected blocks, all of which form a chain of data, which is known as the blockchain. 

So the question remains, how does blockchain secure data? Major blockchain features and benefits account for the issues of security and trust in multiple ways. First, new blocks are always stored linearly and chronologically. The new information is always added to the “end” of the blockchain. 

After a new block has been ended to the back of the blockchain, it is almost impossible to go back and alter the contents of the block unless it is the major consensus to do so. The reason it is considered secure is that it each block contains its own hash, alongside the hash of the block before. A hash code is built using a mathematical function that turns information into a string of numbers and letters. This is how blockchain works in banking and other financial transactions like bitcoins.

Types of Identity Theft

Another common type of online fraud is identity theft, the growing rate of identity theft is alarming. Most people aren’t even aware that their identity has been stolen after the damage has been done. Now that we know how does blockchain secures data, we can discuss how blockchain prevents identity theft. Here are the most common types of identity thefts. 

1. Driver’s License Identity Theft

Anyone that has access to your driving license can make use of your sensitive information and commit fraudulent activities. They can open credit card accounts or use the stolen identity theft if caught for reckless driving. 

2. E-Commerce Fraud

Online identity theft is basically cybercriminals stealing your information like payment details and credentials. Using this information, these criminals can make all kinds of unauthorized transactions. All these transactions will end up hurting your bank balance. This is one of the most common types of identity theft. 

3. Mail Identity Theft

Your mailbox can be vulnerable to all kinds of cyberattacks. One out of 3 identity theft is done via email. Your mailbox contains all kinds of sensitive information including bank information, several login details, or insurance data. This crucial information can be used for all kinds of fraudulent information. 

4. Social Security Number Theft

The social security number is provided to a citizen from the time of their birth. The nine-digit number contains information like financial records, including bank details and a person’s earnings. Now imagine someone gets hold of your social security number, they can use the information for all kinds of purposes. 

If they can use your financial information, they can fill in fake account opening forms or even withdraw money from a person’s account using social security number. More than that, attackers can use your social security number to gain a tax refund. Social security number theft is another common type of identity theft.

5. Synthetic Identity Theft

Synthetic identity theft is a tricky type of identity theft. It is where an attacker mixes stolen information with fake details to create a new fake identity for committing a crime. This newly made identity can then be used to execute all kinds of fraudulent practices. 

How Blockchain Prevent Identity Theft?

Identity theft is a part of online fraud, and it is growing at an alarming pace. A lot of people nowadays are aware of data breaches, but not many are aware that identity theft occurs every two seconds around the globe. In this perilous time, the need for securing one’s identity is crucial, and the way to do that is by safeguarding your documents. Now that you know about types of identity theft, here’s how blockchain prevents identity theft

Blockchain against fraud technology has been taken into consideration since the rise of cybersecurity. The incredible technology holds brilliant potential for securing sensitive data from malicious activities.

Since blockchain contains digital assets including documents that are secured via powerful cryptographic keys. This is one of the primary reasons why it is harder for attackers to manipulate information stored in the blockchain. The data is stored on multiple computers on a blockchain network, so if someone wants to access crucial information, they will have to gain access on all computers which is almost impossible in all cases. Even if the hackers happen to gain access to data, any change they make to the data will be highlighted in the information. This is what blockchain unique and suitable to secure data. Now you know how blockchain prevents identity theft.

Storing any identity information on a blockchain will help both government and the public to prevent identity theft. This is how blockchain works, and the blockchain features and benefits are slowly causing it to come into mainstream adoption. 

While blockchain is still a growing technology, it has countless possibilities for securing data. As the current measures for identity information storage are being attacked and breached, the use of blockchain for fraud prevention is at an all-time high. 

Blockchain Features And Benefits

1. Blockchain Is Distributed

A blockchain is a type of distributed digital ledger which contains transaction data that is hosted on a peer-to-peer network. There is no centralized administrator so there’s no one point of failure that can be accessed for information breach. Instead of a single point, the management and authorization are spread all over the network. 

2. Blockchain Is Unyielding

Another blockchain feature and benefit is that any transaction or information recorded on the blockchain is unchangeable as the information can’t be deleted or changed. While you can create a new transaction to change the state of any asset, the new information will just be added to the chain. 

3. Blockchain can be Permissioned

Businesses of all kinds tend to deal with a lot of confidential data and they can’t have just about anyone access the vital information. So they have to find some way to make sure that outsiders can’t access their data. This is where permissions come into play. You should know that not all blockchain is permissioned. This is why permission networks can be a great solution for fraud prevention because they can restrict who can access the data. 

How DIRO Makes Use of Blockchain For Document Verification?

Till now we have discussed, how does blockchain secure data, how blockchain work, the types of identity theft, and how blockchain prevent identity theft. A major part of all the information and the data breach are documented, most of the online frauds are conducted by using fake or tempered documents. 

A person who steals an identity can open a new bank account and use that bank account for many fraudulent activities. That’s where the innovative technology for document verification by DIRO comes in. It verifies any online original information on the web with automatic user consent and impersonation checks. You can verify any bank statements, proof of address, student certificates and so much more.

Once DIRO verifies a piece of information, it provides a trusted certificate that ensures a document is original. This original document can then be shared in the form of a PDF. DIRO provides the digital document with a unique hash, which then is placed on a blockchain. use this information to verify the documents that are already on the blockchain.

So banks, financial institutions, and others can drop this PDF into DIRO’s verification engine, which verifies the information against the blockchain. DIRO’s original documents are much more secure to share as the information can’t be tampered with by attackers or anyone else. Organizations can use DIRO’s software to minimize online fraud.


What is Blockchain Technology and How Blockchain Works?

Blockchain technology, also known as Distributed Ledger Technology (DLT), helps in maintaining the history of any digital asset immutable and transparent. The technology uses decentralization and cryptographic hashing to make the data unchangeable and transparent. While blockchain is widely popular in the cryptocurrency industry, other industries don’t know what is blockchain technology or how blockchain works?

A simple way to define blockchain technology is like Google Doc. Let’s say that you create a Google Doc and share it with a bunch of people, the document is distributed instead of transferred. This sharing of documents creates a decentralized distribution chain, which gives everyone access to the same information at the same time. Everyone can access the information and data at any given time, not a single person is in charge of changing and sharing the information.

As all the involved parties can see the changes being made in real-time, transparency of data is ensured. If you’re wondering how does blockchain secure data, then you should know the technology follows certain protocols that make the data extremely secure. Using blockchain for fraud prevention is an idea that’s been thought over a lot in recent times. 

While blockchain technology is much more complicated than a simple Google Docs file, it does help in giving an idea to users how blockchain works in banking. Sooner or later, blockchain technology will be integrated into almost every industry.

How Does Blockchain Work?

The main purpose of having blockchain technology is to let people share data, share data in a secure and immutable way. Blockchain technology works on three fundamental principles including blocks, nodes, and miners. 

  1. Blocks

The term blockchain consists of two things, blocks, and chains. Every chain consists of several blocks and it contains 3 main elements:

  • The data in the block.
  • A 32-bit whole number called a nonce, the nonce is randomly generated whenever a new block is created, which then leads to the generation of a block header hash. 
  • The hash is a 256-bit number embedded into the nonce, it has to start with a number of zeroes. 

When a new chain is created, a nonce generates the cryptographic hash. The data in the block is signed and tied to the nonce and has unless it is mined. 

  1. Miners

Miners keep creating new blocks on the chains using a process called mining. In a blockchain every block contains its own nonce and hash, it also contains the hash of the previous block in the chain. Mining for new blocks isn’t easy, especially on large chains. Because the nonce is only 32 bits and the hash is 256, there are billions of combinations till the right combination is found. Whenever the miners find the right combination, a new block is created and added to the chain. 

Making changes to previous blocks in the chain requires re-mining, not just the block with the change but all of the blocks that come after. This is why it is highly complex to manipulate any data on the blockchain. This is how blockchain works in banking, and it is crucial for banks to employ the technology to ensure the safety of data. 

  1. Nodes

One of the most important concepts in blockchain technology is decentralization. Not a single computer or organization owns the chain which makes the information on it transparent. It is an online ledger via nodes that are connected to the chain. Nodes are any type of electronic device that keeps the copies of the blockchain and keeps the network under operating health. 

Combining publicly available information with a variety of checks and balances helps the blockchain maintain integrity and creates user trust among users.

The Rise of Blockchain’s Technology

Most people define blockchain technology as its use in cryptocurrencies. Cryptocurrencies are a type of online currency or online tokens such as Bitcoin, Ethereum, or Dogecoin that can be used to buy goods and services. Just like any digital type of cash, crypto can be used to buy anything from as small as a lunch to as big as a car. Cryptocurrency is not like cash, crypto uses blockchain to operate as a public ledger and as an enhanced security system, so all the online transactions are recorded and secured. 

As of right now, there are around 8,000 types of cryptocurrencies in the world and they have a market value of $1.6 trillion, with Bitcoin being the market leader. Cryptocurrencies are slowly becoming more popular over the years among investors. Here are some of the reason why investors are becoming more and more interested in cryptocurrencies:

  • Blockchain’s security makes the theft of data and information almost impossible as almost all cryptocurrencies have their own indisputable and identifiable number which is attached to one owner. 
  • Cryptocurrencies don’t operate under individualized currencies and central banks. With blockchain, crypto can be sent anywhere in the world without the need for currency exchange or without the interference of central banks. 
  • More and more firms are coming around to the idea of blockchain-based technologies. In February 2021, Tesla announced that they would invest 1.5 billion into Bitcoin and accept Bitcoin as payment of its cars.

How Blockchain Works In Banking?

Apart from cryptocurrency, blockchain technology can also be implied in other industries. Not a lot of people know how blockchain works in banking. Banks and financial institutions can store customer data on blockchain to make sure the confidential customer information stays secure. 

DIRO’s online document verification technology can verify documents instantly. Banks can use the technology and verify customer identity and improve the overall customer experience during remote customer onboarding. DIRO’s technology places verified customer documents on the blockchain to make the information secure and immutable.
