In today’s world, personal data is crucial for industries like online banking, healthcare, social media, and business transactions. Sensitive information—such as bank details, medical records, credit card info, social media activity, and facial recognition—is constantly being shared. With so much data in circulation, how can businesses keep it safe and still use it to their advantage?
This is a challenge many businesses face: they need data to make informed decisions, enhance customer experience, and comply with regulations, but they also must protect privacy and maintain trust. This is where Zero-Knowledge Proofs (ZKPs) come in. ZKPs let businesses verify information (like age, financial solvency, or eligibility) without revealing the actual data, ensuring privacy while still meeting the necessary criteria.
How Do ZKPs Work?
So how exactly does this work? Let’s think about a business centric example:
Let’s say two banks are working together, and one needs to confirm that a customer has enough funds in their account for a transaction. Instead of sharing account details, balances, or transaction histories, the banks can use a ZKP to prove that the customer meets the criteria (having sufficient funds) without exposing the full account details. This not only protects privacy but also helps maintain security in the financial sector.
How ZKPs Assist with Data Protection Compliance
Businesses face the challenge of complying with strict data protection regulations like GDPR. ZKPs help businesses meet these standards by ensuring that only the necessary information is shared—nothing more, nothing less.
For instance, ZKPs help businesses follow the data minimisation principle. Whether it’s confirming a person’s age, financial status, or identity, businesses can verify key details without accessing sensitive personal data.
ZKPs also reinforce the security principle by allowing businesses to prove the truth of a claim (such as a transaction or eligibility) without exposing the underlying data. This helps safeguard privacy, reduce the risk of data breaches, and protect sensitive information.
Challenges and Future Directions
While ZKPs offer great promise, they do come with some challenges. The process of generating and verifying proofs can be resource-heavy, which might slow things down in certain situations or on a large scale. However, researchers are constantly working on improving these systems aiming to make the process faster and more efficient.
Moreover, the future of digital security may see hybrid solutions that combine ZKPs with other Privacy-Enhancing Technologies (PETs) such as Multi-Party Computation (MPC). These hybrid approaches could offer even greater levels of privacy and efficiency, opening new avenues for secure digital interactions.
Revolutionizing Privacy Across Industries
Beyond e-commerce and healthcare, ZKPs are making significant strides in sectors like supply chain management, telecommunications, and legal services.
In supply chains, ZKPs are becoming a game changer by verifying product authenticity and ensuring compliance with environmental and carbon emissions standards—while keeping proprietary business data secure. This is particularly valuable when calculating Scope 3 emissions, which are the indirect emissions from a company’s value chain. For example, as part of the UK government’s push for greater transparency in Scope 3 emissions reporting, companies can use ZKPs to demonstrate that their suppliers are actively reducing emissions. And all of this can be done without revealing sensitive financial or operational details, ensuring privacy while making the process more transparent, efficient, and secure.
The integration of ZKPs across diverse sectors highlights their versatility and potential to revolutionize data privacy and security. As technology evolves, the adoption of ZKPs will continue to grow, offering innovative solutions to complex privacy challenges and paving the way for a future where privacy is the foundation of every digital interaction.
