Google is integrating Zero Knowledge Proof (ZKP) technology into its Google Wallet app to enhance user identity verification. This move allows users to prove their age without revealing their birthdate or personal details. The tech giant is leveraging a concept introduced in the 1980s by Shafi Goldwasser, Silvio Micali, and Charles Rackoff, which has since been developed further in the cryptocurrency industry.
How ZKP Works
ZKP is a cryptographic process that enables one party to prove they possess certain information without disclosing it. Think of it like proving you have a key to a safe without showing it. You can demonstrate you can open the safe without revealing the key. This technology has been used in cryptocurrency projects like Zcash, founded in 2016, and has become a significant use case in the blockchain sphere.
Google’s Implementation
Google is using ZKP to create a digital ID solution within Google Wallet. This allows users to store their identification information securely and verify their age when needed. The feature is initially being rolled out in the UK, with plans to expand to the US and other countries soon. The dating app Bumble will be one of the first to use this new ID verification system.
Google’s goal is to provide a secure and private way for users to verify their age and identity. The company is exploring various use cases for this technology, including offline applications and digital passports. With ZKP, Google aims to ensure that users’ personal information remains protected while still allowing them to access age-restricted content and services.
The introduction of ZKP technology into Google Wallet marks a significant step forward in identity verification. By leveraging advancements from the cryptocurrency industry, Google is creating a more secure and private way for users to manage their digital identities. As this technology continues to evolve, we can expect to see more innovative applications across various industries.
