 In the previous sections, we have outlined how current technologies may impact privacy, as well as how they may contribute to mitigating undesirable effects. However, there are future and emerging technologies that may have an even more profound impact. Consider for example brain-computer interfaces. In case computers are connected directly to the brain, not only behavioral characteristics are subject to privacy considerations, but even one’s thoughts run the risk of becoming public, with decisions of others being based upon them. In addition, it could become possible to change one’s behavior by means of such technology. Such developments therefore require further consideration of the reasons for protecting privacy. In particular, when brain processes could be influenced from the outside, autonomy would be a value to reconsider to ensure adequate protection.
