Show HN: Changefly ID + Anonymized Identity and Age Verification

Summary

By Lukas Dickie, Changefly’s Founder Today I’m excited to share something we’ve been working intensely on: Changefly ID + Anonymized Identity & Age Verification. The keyword here is anonymized. Our digital lives are a constant trade-off between convenience and privacy, where every new account, every login, and every purchase adds another piece of our personal data to a vast, insecure, and interconnected web. This model has led to a plague of data breaches, identity theft, and online abuse. Changefly ID + Anonymized Identity & Age Verification offers a new way forward, one where we can prove who we are — without revealing who we are. Changefly ID addresses these issues with a novel approach: Anonymized Identity and Age Verification. Instead of sharing your personally identifiable information (PII), Changefly ID uses advanced cryptographic techniques to verify your attributes without ever revealing the underlying data. Changefly ID with Anonymized Identity and Age Verification Here’s how it works Zero-Knowledge Proofs: This is the core of the technology. A zero-knowledge proof allows a user to prove a statement is true without revealing any information beyond the validity of the statement itself. For example, a website might need to know if you are over 18. Instead of sending your date of birth, which is sensitive PII, you would provide a cryptographic proof that you are indeed over 18. The website gets the verification it needs, and your privacy remains intact. Secure Multi-Party Computation: This technique allows multiple parties to compute a function over their inputs while keeping those inputs private. In the context of Changefly ID, this could be used to verify that a user is a unique individual without revealing their personal details to any single party. Temporary, Unique Identifiers: Changefly ID replaces traditional login credentials like email addresses, phone numbers, usernames, and passwords with cryptographically secure, temporary anonymous identifiers.
