Abstract : In the IoT era, smart homes are getting increasingly equiped with connected devices, whose implications on privacy remain largely unknown from end users. In this work, I will present the issues that a user can face when installing and using connected devices, by focusing my study on smart bulbs comming from different manufacturers, which are popular and representative. I will analyse the privacy implications of multiple control techniques used for these bulbs (i.e., switching on and off the bulb, using different smartphone applications, smart speakers and smart buttons). I will show that privacy issues in the context of smart homes depend mostly on the control technique chosen by the user to control his device, rather than the device itself. I will show that there are issues concerning sovereignty, data leaks, behaviour inferences, tracking, or even applications design. I will then show the issues concerning application configurations and privacy policies and demonstrate that manufacturers cannot pretend to collect a valid consent from users. I will highlight that, in most cases, the end user cannot reasonably understand the situation which is too complex (different protocols, volume of shared data, lack of knowledge). Hence, the current situation is neither privacy-preserving, nor legal (no consent), nor sovereign (dependancy on remote actors). Therefore, I will sugest some ideas to solve these issues, like using connected devices and applications that can work locally, or creating tables of consent in order to easily define what a user consents to exactly.
