Overview
The key features of the SocialMix model include communication privacy through k-anonymization and intelligent mix node selection methods to reduce the risk of the adversary's attempt to break the privacy.
Approach
SocialMix shuffles the messages through message aggregation so that the relationship between the content of a message and the poster’s identity can be anonymized and perturbed. SocialMix aims at ensuring high degree of user privacy while keeping communicating ver a trusted over anonymous social network.SocialMix network - an example
- Suppose we have a network with 10 nodes.
- A,B,I,J send messages to D,H.
- <tA,A,MA> denotes that node A sends message MA at time tA.
- D,H work as event-driven Mix nodes, also called pre-mix nodes.
- Node E works as intermediate mix node, also called post-mix node.
