# Lab 1: Security Requirements

## Metaverse User Stories

`Metaverse Users` are referred to as users here.

User | Task | Goal | Context | Action | Outcomes
-- | -- | -- | -- | -- | -- 
User | perform authorized payment transactions | only I can make transactions in my name | An adversary knows my payment information | he tries to pay with my info | the payment is declined if not authorized by me
Developer | access user configurations (avatars, config) | personalize the user experience of my applications
Teacher | make physical course material available in the metaverse | students can see them in virtual reality
User | have a unique identification key in bound to my avatar | everyone can recognize my avatar | my avatar is public | my avatar is used by another user | the user cannot impersonate my identity because he doesn't know the key
User | virtual home to be self or zero knowledge hosted | my privacy can not be intruded

Corrections:

- User stories are more non-functional and should not contain less security aspects, rather the use-case functionality

User | Task | Goal
-- | -- | --
User | perform a payment | i can acquire an virtual/physical asset
