**News Flash: Decentralized Blockchains to Revolutionize Biometric Data Security**

Biometric data collection by tech giants like Google and Apple exposes users to multiple risks and high costs. Evin McMullen, co-founder of Privado ID, highlights how decentralized blockchains can mitigate these issues.

- **Complex Supply Chains:** Biometric data often passes through various service providers, increasing exposure to third parties.

- **Zero-Knowledge Proofs:** This cryptographic method verifies data without revealing its contents, enhancing privacy.

- **Economic Incentives:** Avoiding biometric data storage can save companies on cybersecurity and compliance costs.

- **Human Rights Concerns:** Centralized databases risk misuse, as seen historically during WWII.

Decentralized solutions offer a more secure and cost-effective approach to managing biometric data.
