Signal has sharply criticized a new UK government proposal that would require technology companies to prevent children from taking, sharing, or viewing nude images on smartphones and tablets, calling the approach “dystopian” and warning that it could create a foundation for broader surveillance.
The proposal was announced as part of the UK government’s latest child safety initiative. Officials have given major technology companies, including Apple and Google, three months to implement safeguards capable of detecting and blocking explicit images on devices used by children. If companies fail to act, the government has said it is prepared to introduce legislation requiring compliance.
According to the government, the measures are intended to reduce child exploitation, sextortion, and the sharing of explicit content involving minors. Adults would still be able to access and share such material after completing age-verification checks.
Signal has emerged as one of the most vocal opponents of the plan. In a public statement released after the announcement, the encrypted messaging provider argued that requiring devices to scan content and verify users’ ages would not improve safety and would instead weaken privacy protections for everyone. Signal said forcing people to prove their age or submit to device-level content scanning in order to communicate creates a dangerous precedent.
The company also warned that systems introduced for child protection could eventually be expanded for other purposes.
Signal said that once content-scanning infrastructure exists, governments may broaden its use beyond nudity detection to other categories of content. The organization argued that promises limiting the technology’s scope provide little reassurance because future governments could redefine what the systems are designed to detect.
Privacy advocates have echoed similar concerns. Digital rights groups argue that device-level scanning and mandatory age verification could significantly reduce online anonymity and increase the amount of personal information collected by technology companies. Critics say the proposal risks creating surveillance capabilities that extend well beyond the government’s stated objectives.
The UK government rejects those criticisms. Home Secretary Shabana Mahmood has said the initiative is focused on protecting children from predators, coercion, and sextortion rather than monitoring the public’s private communications. Government officials maintain that the measures are designed specifically to address child safety risks on digital devices.
Technology companies now have until September to demonstrate how they will meet the government’s demands. If regulators determine that voluntary measures are insufficient, the UK has indicated that new legislation could follow, potentially introducing fines and other penalties for non-compliance.
