I think the common factor that applies horizontally to all stakeholders who would like to use facial recognition is the principle of necessity and proportionality that my two colleagues mentioned. That applies to all stakeholders: police services, businesses and other departments and governments.
In police services, however, the use of facial recognition can have extremely serious consequences, resulting even in the loss of freedom. I would say that many common principles should be considered. All stakeholders, including legislators, had to consider the context and consequences of the use of this technology. For example, a total prohibition of its use by police services in certain circumstances might not necessarily apply to all stakeholders.
