The European Commission has proposed a bill called Chat Control, which would require messaging services to scan users' communications for child pornography material. The bill has been met with criticism from experts and advocacy groups, who argue that it would infringe on citizens' right to privacy and could lead to mass surveillance. The proposal has been linked to American tech companies and security services, which would benefit from the introduction of such technology. The bill has been rejected by several legislative bodies due to its incompatibility with human rights and the potential for false positives.
