While there are clearly now multiple efforts to curtail the use of facial recognition technology (FRT) in the public realm, the reality is that the genie is already out of the bottle and there is no way to put it back.
The efforts above range from limited bans within the public sector, to reviews of new implementations of the tech, to specific court cases against police use of FRT. In short, it’s a patchwork of efforts, and there are huge gaps between them. Many examples also tend to focus on State-backed projects, rather than in the private sector – which is also experimenting with the tech, often in the public domain.
Meanwhile, the technology and its use is still rapidly spreading around the world, and there remains as yet no fully tested national position on its use in countries such as the US and UK.
