Biometric data collected by tech companies poses risks to users and burdens tech firms with high costs. Evin McMullen, Privado ID co-founder, explained how decentralized blockchains can address these risks. Biometric data often flows through various service providers, exposing it to multiple third parties. Zero-knowledge proofs can limit data exposure by verifying information without revealing its contents. This approach allows users to control access to their biometric data using blockchain keys. Collecting biometric data entails cybersecurity, compliance, and storage expenses, making it economically beneficial for businesses to avoid storing such data. Centralized storage of biometric data by tech giants creates security vulnerabilities, which decentralized blockchain solutions can mitigate. Additionally, centralized biometric databases raise concerns about human rights abuses. Decentralized blockchain identity solutions offer a more secure and privacy-focused alternative to traditional tech practices. Read more AI-generated news on: https://app.chaingpt.org/news
