Title
Privacy Leakage in Smart Homes and Its Mitigation: IFTTT as a Case Study
Abstract
The combination of an appified smart home platform and third-party apps have enabled developers to contribute their novel ideas to bring more convenience to their users. However, this also brings the potential of privacy leakage. If a third-party app is permitted to monitor a user day and night, then it will learn the behavior pattern of this user before long. In this paper, we exploited how IFTTT monitors the daily life of a user in several ways that are hardly noticeable. We propose the “Specific-fuzzification” to protect the privacy of a user in two steps: filter the unnecessary events to the IFTTT, then fuzz the value of the events that must be uploaded. We evaluated the “Specific-fuzzification” on event records of seven users, the result showed comparing the original IFTTT, the modified IFTTT patched with “Specific-fuzzification” only gained rare events and thus could no longer recognize any behavior patterns of a user.
