Common issues to consider while developing for Mixed Reality
What are some of the security issues with Mixed Reality Applications?
Since a Mixed Reality application might have access to the user video stream, developers might be able to save or share private information about the user. Be careful to not to save any sensitive data or image anywhere other than users device. Never send sensitive information to any backend.
Why is eye scan data sensitive information?
