Decentralized Biometrics Can Avoid Risks of ‘Service Provider Supply Chain’: Privado ID Co-Founder

Privado ID co-founder Evin McMullen is making the case for a decentralized approach to the storage of biometric data. Speaking to Cointelegraph, McMullen argues that the centralized storage and processing of biometric data by Big Tech companies introduce significant cybersecurity risks and raise privacy concerns. McMullen highlights how biometric data often travels through a “complex supply chain of service providers” that assess the data’s validity, exposing sensitive information to multiple third parties.

To mitigate these risks, she advocates for using decentralized blockchain systems with zero-knowledge proofs. This approach allows users to control access to their biometric data by verifying information without revealing specific details, thereby limiting data exposure. McMullen suggests that blockchain keys can serve as a mechanism to regulate who has access to this data, ultimately promoting a more secure and private approach to biometric management.

McMullen further contends that the economic and security burdens of centralized biometric data storage make it advantageous for companies to avoid holding such data. She explains that tech firms face substantial costs related to compliance with regulations like the GDPR and are also vulnerable to security breaches due to their “centralized points of failure.”

She also raises ethical concerns, noting the potential for centralized biometric databases to be misused in ways that violate human rights. McMullen uses historical examples, such as the systematic targeting of minorities during World War II through comprehensive records, to emphasize the importance of privacy as a human right and the risks of centralized data collection.

Formerly known as Polygon ID, Privado ID is a digital identity management platform that was recently spun off from Polygon Labs to operate as an independent entity. The company was officially launched on June 13, 2024, although its technology has been in development for longer as part of the Polygon ecosystem.

The platform uses zero-knowledge proof (ZKP) technology to provide secure and efficient identity verification solutions while giving users control over their personal information. Privado ID offers features such as verifiable credentials, in-app identity verification, and reusable credentials across different applications and platforms. It supports W3C identity standards and is compatible with EVM (Ethereum Virtual Machine) chains, with plans to expand to non-EVM blockchains in the future3.

Privado ID’s ecosystem consists of open-source software and infrastructure for developers, along with a marketplace of trusted, reusable credentials. The platform can be used for various applications, including streamlining identity verification for financial institutions, enhancing compliance in decentralized finance, verifying digital content authenticity, and implementing airdrops in blockchain ecosystems.
