Because biometric data cannot be replaced, storing the data requires the highest levels of security, Evin McMullen told Cointelegraph.
Biometric data collected by the tech industry introduces multiple risk vectors to end users and imposes massive costs on tech companies.
Evin McMullen, co-founder of Privado ID — a decentralized identity project that uses zero-knowledge cryptography — recently explained to Cointelegraph explain how decentralized blockchains mitigate these risks.
McMullen began by pointing out that biometric data isn't just processed or stored through traditional Big Tech companies like Google, Apple, or Microsoft. Instead, the data often passes through a complex supply chain of service providers that opine on the validity of certain pieces of data, which exposes user data to multiple third parties. The Privado ID co-founder stated:
