The challenge which was raised was striking a balance between offering users control over their data and avoiding overwhelming them with choices. A key recommendation in terms of balancing control was to allow users to specify their preferences in advance rather than being asked each time they use a skill. Yet there is still a need for further research into the role of joint controllerships in VA platforms, and into how consent can be made more nuanced to offer users greater control. Collaboration between developers and regulators, to ensure that VA platforms comply with privacy legislation and offer users effective privacy choices, would represent an important step towards ethical best practices.
In conclusion, the study shows that verbal consent mechanisms for VAs can increase usability, but they can also undermine principles core to informed consent. Users must be given the option to opt-out of data sharing. The study’s recommendations provide valuable guidance for regulators, skill developers, and VA platforms towards crafting meaningful verbal consent mechanisms in VAs and other conversational interfaces. It is essential to align how verbal consent is managed and perceived before bad practices are embedded in conversational interfaces that will later prove difficult or impossible to change.
It is worth noting that the study assumes a European perspective and that GDPR applies. Full details of the survey and analysis are provided as supplemental material and archived at https://osf.io/4vu67.
