Privacy

Privacy is the cornerstone of XSTAR, with contributors dedicated to exceeding current best practices to ensure privacy is accessible to everyone. Third party providers of biometrics, offer a highly privacy-preserving solution for proof of humanity, such as XNAME. Achieving robust privacy requires intentional effort and demonstrable results to build trust. This section delves into the advanced technical details of how privacy is maintained within the XSTAR ecosystem.

XSTAR's critical systems are designed so that privacy cannot be compromised, even by protocol contributors. This is accomplished using cryptographically provable mechanisms such as Zero-Knowledge Proofs (ZKPs) scaled up in stage 3, which make it mathematically impossible to link XNAME usage across applications. These privacy protections surpass regulatory requirements.

Users can utilize the XNAME App and XNAME fully anonymously, without needing to provide personal information such as emails, phone numbers, or names.

In stage 3 Zero-Knowledge Proofs (ZKPs) ensure user privacy. ZKPs validate a user's uniqueness without disclosing their XNAME or wallet public key, ensuring anonymity across applications. Additionally, XNAME usage is not linked to biometric data, allowing users to prove their uniqueness without revealing any personal information.

Local Enclave Storage refers to the practice of storing personal data (including images, metadata, and biometric information) on a user’s device. Allowing users control over their data, with the ability to manage its use and deletion.

Local Enclave Storage not only provides users with control but also enables new XNAME use cases, such as Proof of Humanity (PoH) for high-security applications. With PoH, users can confirm their identity locally on their device without their face data leaving their phone.

For XSTAR, Local Enclave Storage represents a significant step towards reinforcing a user-centric architecture and enhancing the security of the XNAME network.
