HideDroid

HideDroid allows the per-app anonymization of collected personal data according to a privacy level chosen by the user.

In a nutshell, HideDroid collects all the network traffic generated by the invocation of API calls belonging to analytics libraries, and extract the exported data. Then, it anonymizes the personal and device data using a generalization technique, and the data related to the user’s behavior using an approach based on the concept of local differential privacy, in a way that preserves as much data semantics as possible. Finally, the anonymized data are sent to the expected recipients by mimicking the original network calls.
