Biometric data collected by the tech industry poses many risks to end users and imposes significant costs on tech companies. In an interview with Cointelegraph, Privado ID co-founder Evin McMullen explained how decentralized blockchains mitigate these risks.
McMullen noted that biometric data is not only processed by traditional Big Tech companies like Google, Apple, or Microsoft, but also passes through a complex supply chain of service providers. This exposes user data to many third parties.
McMullen said that zero-knowledge proofs â a method of verifying data without revealing its content â would limit this data exposure. He noted that we could use our blockchain keys to control who has access to our biometric information.
Collecting biometric data creates significant cybersecurity, regulatory compliance, and storage costs for tech companies. McMullen said it is in the economic interest of many businesses to avoid storing biometric data.
He also noted the potential for centralized biometric databases to be used for human rights violations. McMullen said that II. He cited the role of biometric data in the systematic persecution of ethnic minorities during World War II.
