We’ve all experienced it — identity verification. When going on a plane, when entering a festival, when making a big purchase. Who knows…
Verifying your identity can be very important, but it can also be a big hassle. It doesn’t have to be. With the use of blockchain, it could be so much easier.
In this article, we’ll explore how blockchain can be used for identity verification, why it works, and the road to actually realising it. Let’s get into it!
The Problem with Identity Verification
Identity verification has always been a serious issue, but in today’s day and age, it’s more important than ever before. Traditional methods rely on personal documents and credentials, but they certainly have their limitations.
According to the FBI, over 100,000 identity theft and personal data breaches occur annually, with 50,000 cases of identity theft and over 50,000 personal data breaches reported in the US alone. And likely, the numbers are much higher in reality, as many cases go unreported.
Sadly, there are still many limitations of traditional identity verification methods that allow these cases to happen. Here are some of those limitations.
Vulnerability to data breaches. Centralized databases are attractive targets for hackers, exposing sensitive data of thousands or millions of individuals.
Lack of privacy. Sharing extensive personal information increases the risk of privacy invasion and identity theft.
Inefficiency and delays. Manual verification processes are time-consuming and prone to errors, causing delays in accessing services or conducting transactions.
Fragmented verification systems. Different organisations maintain separate identity verification systems, making it challenging to establish a unified approach.
Emerging challenges in the digital age worsen these limitations. Increased reliance on digital interactions and online platforms expands the attack surface for identity-related crimes. Synthetic identities, deep fakes and sophisticated phishing techniques make it even more complicated.
To address these challenges, innovative solutions are needed. And blockchain technology might just be that solution. It might just be what will enhance security, privacy and efficiency in identity verification. But how? First, let’s take a look at what blockchain is precisely.
Introducing Blockchain
Imagine a game of basketball where each player keeps track of the score. Instead of relying on a single referee to maintain the official record, every player in the game has a copy of the scorebook. It sounds pretty crazy, right? Well, maybe it is. But one thing’s for sure — the score at the end of the game will be correct.
For a game of basketball, this might not be too important. But, in some other scenarios, being able to know for sure that what’s stated is correct is absolutely crucial. This unique way of basketball scoring is similar to how blockchain works, where multiple participants maintain a shared record, known as a distributed ledger.
Blockchain is a decentralized technology that enables secure and transparent transactions and information storage. It is a digital ledger consisting of a chain of blocks, where each block contains a list of transactions or data. What makes blockchain special are some of its key features.
Decentralization
Unlike traditional systems that rely on a central authority, blockchain operates in a decentralized manner. It means that no single entity has control over the entire network, making it resistant to manipulation or hacking.
Transparency
Blockchain provides a transparent and immutable record of transactions. Every participant can view and verify the data stored on the blockchain, promoting trust and accountability.
Security
Blockchain employs cryptographic techniques to secure the data. Each block is linked to the previous one using a unique cryptographic hash, creating a chain of blocks that are virtually impossible to alter without detection.
Distributed ledger technology — which is the underlying concept of blockchain — offers several benefits. By distributing copies of the ledger to multiple participants, it enhances reliability and eliminates the reliance on a single point of failure. This redundancy makes the network more resilient to attacks and ensures that the data remains intact even if some participants go offline or get hacked.
People often link blockchain to cryptocurrencies, which make total sense — as so far that’s what it’s known for in the general public. But actually, it’s not entirely fair. Blockchain can do so much more than just host cryptocurrencies.
For example, it can be of great value in supply chain management. Blockchain can enhance transparency and traceability in supply chains by recording every step of a product’s journey. It enables efficient tracking of goods, reducing fraud, counterfeiting and ensuring the authenticity of products.
Another example is the healthcare industry. Blockchain can securely store and share medical records, ensuring data integrity and streamlining access for healthcare providers. It can also facilitate the verification and authorisation of medical prescriptions, improving patient safety.
But that’s not all — it could also change voting systems forever, as it offers a secure and transparent platform for conducting elections. It can enhance the integrity of the voting process by preventing tampering, ensuring anonymity, and increasing public trust in the outcome.
These are just a few examples of the wide-ranging applications of blockchain technology. But, we wouldn’t be here writing this article if blockchain couldn’t also help with identity verification. Let’s get into how it can, exactly.
How Does Blockchain Help with Identity Verification?
Another example: imagine attending a music festival where each attendee carries a unique wristband with an embedded chip. This wristband not only grants access to different areas but also securely stores personal information.
Now, instead of relying on centralized checkpoints and IDs, attendees can simply tap their wristbands on scanning devices placed throughout the venue. These devices instantly verify their identities, ensuring a seamless and secure experience. How cool, but especially convenient, would that be?
Well, that’s exactly what blockchain technology can make possible. It mirrors how blockchain technology can revolutionise identity verification by providing secure, decentralized, and efficient solutions. But let’s take a look at some specific examples in the case of identity verification.
Self-Sovereign Identity (SSI)
In today’s world, self-sovereign identity is just like carrying a digital wallet where individuals have full control over their personal information. Just like a physical wallet, you decide which credentials to carry and share.
Blockchain allows individuals to store their identity attributes in a secure and tamper-resistant manner, granting them the power to share specific details with trusted entities when needed, and close it off from people they don’t want seeing it. It empowers individuals to manage their data, reducing the risk of breaches and identity theft.
Digital Passports
Think of blockchain-based digital passports as your personal travel companion. Instead of carrying physical passports and relying on border control authorities, your digital passport securely stores your verified identity information.
With a simple scan or tap, border control officials can access the encrypted information stored on the blockchain, verifying your identity and facilitating seamless travel. This eliminates the need for physical documents, reduces the risk of counterfeit passports, and enhances border security.
Decentralized Trust Networks
Traditional identity verification often involves relying on centralized authorities, such as banks or government agencies, to confirm an individual’s identity. However, blockchain introduces the concept of decentralized trust networks.
Imagine a web of trust, where each person is a node connected to others. By leveraging blockchain’s decentralized nature, these networks enable identity verification through consensus among trusted participants.
Similar to how a sports team relies on trust among teammates to achieve a common goal, decentralized trust networks create a web of trust to establish and verify identities.
Tamper-Resistant Records
Just as a sports referee’s decisions are final and indisputable, blockchain’s tamper-resistant records provide an immutable and auditable history of identity-related transactions.
Once information is recorded on the blockchain, it cannot be altered or deleted without leaving a trace. This ensures the integrity of identity verification processes and reduces the risk of fraudulent activities.
The Pros and Challenges of Blockchain in Identity Verification
So overall, implementing blockchain technology in identity verification seems like a very good idea. It has many pros. And sadly, but obviously, there are also some challenges that come with it. Let’s take a look at both the pros and the challenges.
The Pros
There are many, many pros that come with implementing blockchain in identity verification, but let’s take a look at some of the most notable ones.
Enhanced security. Blockchain offers robust security features, including immutability and cryptographic protocols, which significantly reduce the risk of identity theft, data breaches and unauthorised access.
Improved privacy. Blockchain-based identity verification allows individuals to have greater control over their personal data. Users can selectively disclose specific attributes while keeping the rest of their information private.
Increased trust and transparency. Blockchain’s transparent and open nature creates trust among participants. The shared ledger provides a transparent record of identity verification transactions, allowing for easy verification and validation.
Cost savings. Implementing blockchain-based identity verification systems can lead to cost savings for organisations. By reducing manual processes, eliminating intermediaries and enhancing efficiency, blockchain technology can lower operational costs associated with identity verification.
The Challenges
