The report highlights Iran’s escalating reliance on technology to monitor and punish women defying the mandatory dress code. Central to this crackdown is the “Nazer” mobile application, a government-backed tool that allows citizens and police to report women for alleged violations.

Iranian officials are encouraging people to report women who refuse to obey the Islamic republic's dress code, according to a UN report.

A U.N. fact-finding mission into Iran's treatment of women reported that the Islamic republic was resorting to extreme measures in its drive to restrict their rights, including electronic surveillance and camera-drones.

Iran is increasingly deploying advanced surveillance technology, including drones, facial recognition, and a government-backed mobile app, to enforce its mandatory hijab laws, CNN reported citing a United Nations report released Friday.

Iran increasingly relies on electronic surveillance and the public to inform on women refusing to wear the country's mandatory headscarf in public, even as hard-liners push for harsher penalties for those protesting the law.

Then, according to the report, the app "triggers a text message (in real-time) to the registered owner of the vehicle, warning them that they had been found in violation of the mandatory hijab laws, and that their vehicles would be impounded for ignoring these warnings.
