Traditional methods of identity authentication often face limitations in security and reliability, exposing user data to potential breaches. Blockchain, however, offers a compelling solution. This article explores how blockchain technology is changing the way industries approach customer verification.
Blockchain and Identity Verification and Management
Customer verification is critical in ensuring the security of accounts and transactions. Traditional identity management systems relied on trusted authorities to issue and manage credentials. This centralised nature makes them lack transparency and vulnerable to data breaches.
Blockchain presents a transformative solution for this issue. This distributed ledger technology offers a secure and transparent way to store and manage data. Each piece of information is cryptographically linked within a chain of blocks. Each block in the chain contains a unique cryptographic hash, acting as a digital fingerprint. And, lastly, each block’s hash incorporates the hash of the preceding block.
This makes it virtually impossible to tamper with the data once recorded. Any attempt to alter information in a previous block would change its hash, triggering a cascade of changes throughout the chain and exposing the tampering. This inherent security significantly reduces the risk of identity theft and fraud compared to traditional methods.
Another core strength of blockchain technology lies in its inherent transparency. Blockchain technology permanently records every transaction and instance of data entry on a shared ledger, accessible to all participants in the network. This fosters trust by promoting accountability and facilitating immediate verification for activities like dispute resolution.
How Blockchain Improves Efficiency
Customer onboarding for financial institutions hinges on verifying a customer’s identity. Traditionally, this involves multiple document submissions across various institutions. Blockchain technology streamlines this process.
One approach involves storing encrypted personal information (PII) like passports or driver’s licences on the blockchain. Customers would then grant permission to specific institutions to verify their identity. This eliminates the need to repeatedly submit documents for each new financial relationship.
It also creates a more reliable data source for institutions since everyone would be referencing the same information. Additionally, customer control over access simplifies compliance with privacy regulations.
Case Studies
One example of how financial institutions are leveraging blockchain technology for customer verification is Tradle, a Know-Your-Customer (KYC) platform built on blockchain. This platform utilises bots to scan relevant customer information, such as financial data and employment history, providing banks with verifiable background checks to streamline loan approvals.
The gathered information is then secured on the blockchain for both internal bank transfers and external data sharing, ensuring its immutability and trustworthiness. This approach offers financial institutions a secure and efficient way to conduct KYC checks, potentially reducing processing times and fraud risks.
Future Outlook
The future of digital identity management appears to be closely linked with the potential of blockchain technology. A report by Market Research Future predicts a surging market, reaching a valuation of $17.81 billion by 2030, driven by government initiatives that promote blockchain development worldwide.
Blockchain’s core strengths—security and transparency—offer a compelling alternative to traditional identity management systems. Ongoing advancements in blockchain technology and a growing focus on digital identity security point towards a promising future.
