The collection of biometric data in the tech industry introduces many risks for users and substantial costs for companies. Evin McMullen, co-founder of the decentralized identity project Privado ID, shared insights on how decentralized blockchain can alleviate these concerns.

Biometric Data Risks and Decentralized Solutions

McMullen pointed out that biometric data often passes through a complex web of service providers, increasing the risk of exposure to third parties. She suggests that data should be shared on a 'need-to-know' basis and remain on the device without connecting to the internet. McMullen recommended the use of zero-knowledge proofs to limit the exposure of biometric information and ensure user control over data access.

Cybersecurity Threats and the Cost to Companies

Handling biometric data is a costly venture for companies, including costs for cybersecurity and compliance with regulations like GDPR. The decentralized nature of blockchain technology minimizes central points of failure, prime targets for cyberattacks. McMullen noted it is economically beneficial for businesses to avoid storing biometric data due to complexities in handling deletion or amendment requests. Decentralized identity solutions offer more secure data handling, reducing such risks.

Need for Decentralized Blockchain Solutions

McMullen raised concerns about the potential misuse of centralized biometric databases in human rights violations, citing historical events where data was weaponized against ethnic minorities. This underscores the importance of decentralized blockchain not just as a technical solution but as a safeguard for human rights.

Implementing decentralized blockchain systems for managing biometric data can reduce risks and costs for companies while protecting human rights.
