The United Nations report was a report that investigated the application of artificial intelligence systems that affect the lives and livelihoods of people, without putting in place appropriate safeguards to protect and prevent discrimination and other harms.
China is among the most prominent countries that have deployed face scanning and recognition technology, especially as part of surveillance in the western region of Xinjiang, where many of the Muslim Uighur minority live.
Bachelet has not explicitly called for a ban on facial recognition technology, but said governments should stop examining people's traits directly so they can be sure the technology is accurate, does not discriminate and meets specific privacy and data protection standards.
In a statement, Bachelet said that states should publicly ban AI applications that are inconsistent with international human rights law.
The applications that should be banned include government “social assessment” systems that judge people based on their behavior, as well as certain AI-based tools that categorize people by groups such as race or gender.
Bachelet considered that AI-based technologies may be a "force for good", but that they may have "negative or even catastrophic effects if used without adequate consideration of how they affect human rights."
The UN report expressed concern about tools that try to discover people's psychological and emotional states by analyzing their facial expressions or body movements, saying that such technology is subject to bias, misinterpretation and understanding, as well as lacking a scientific basis.
