Google has introduced Zero-Knowledge Proof (ZKP) technology to its Google Wallet service, allowing users to verify their age without sharing personal information. This cryptographic technology is a significant turning point for online privacy protection, as it eliminates the risk of privacy violations and identity theft. The system uses blockchain technology to process the condition (age) in encrypted form, generating a proof that can be verified by an external service through public keys. Unlike traditional methods, the ZKP system maintains total control over users’ information. Bumble, a popular dating app, will use digital IDs issued through Google Wallet to verify their age, while the confirmation will be managed through the ZKP system. This will improve the user experience and increase trust in the platform. The adoption of ZKP technology by Google could mark a decisive turning point, attracting attention from developers, companies, and investors in the decentralized privacy sector. The future of age verification and digital identity could be marked by a greater balance between security and privacy. If successful, the adoption of systems based on ZKP could lead to a safer and more respectful internet for individuals.
