Deliverable 2
Description: Add differential privacy to fuzzify number of users in groups. This deliverable ensures that Yioop is protected against statistical attacks
Implementation steps:
- Identify instances in the UI where the statistic - number of users in a group - is displayed
- Locate the Controller where group activities are handled
- Identify and understand the working of the function that displays group users data
- Understand the database function that fetches group users data from the database
- Apply differential privacy to number of users in a group
Discoveries:
- Controller where group activities are handled : SocialComponent
- Function that displays group users data : getGroupUsersData()
- Function to fetch group users data from DB : countGroupUsers()
Results:
Create a group test with 3 users: root, user1 and user2
Login as user1 and check if number of users is fuzzified
Login as root and check if number of users is fuzzified
