Google has indeed upgraded its Wallet service with a focus on user privacy. Here's what's new :
- *Zero-Knowledge Proof (ZKP) Technology*: Google is using ZKP for age verification, allowing users to confirm their age without sharing personal data. This technology ensures secure verification without revealing underlying information.
- *Digital IDs*: Google Wallet's digital IDs will be used for user identity verification in collaboration with apps like Bumble. Bumble will utilize Google Wallet's digital ID to verify user identity and ZKP to verify age.
- *Selective Disclosure*: Users have control over what information they share, and only relevant data is disclosed to relying parties.
- *Open-Source Plans*: Google plans to open-source its ZKP tools, enabling other wallet providers and developers to adopt privacy-first authentication systems.
- *Partnerships and Expansion*: Google is working with governments, regulators, and industries to build a trusted digital identity solution. The company has already added support for UK passports and more US state IDs.
The implementation of ZKP technology is live in Google Wallet and works across mobile devices and apps using Google's Digital Credential API. This development is seen as a significant step towards mainstream adoption of privacy-driven innovations, with potential applications in various sectors beyond age verification .
