Google has announced a major update to its Google Wallet service, introducing an advanced cryptographic technology called Zero-Knowledge Proof (ZKP).
This system allows users to verify their age to access restricted services without having to share personal information such as date of birth or identity documents.
A significant turning point for the protection of online privacy, in an era in which data protection is increasingly crucial.
How Google’s age verification works with Zero-Knowledge Proof (ZKP)
The Zero-Knowledge Proof technology allows a user to prove information – for example, being over 18 years old – without revealing how they know it or other personal details.
This is possible thanks to a system based on blockchain, which processes the condition (in this case, the age) in encrypted form.
The system generates a proof that can be verified by an external service through public keys, thus ensuring the validity of the information without exposing the
