South Korea’s police forces are developing a new deepfake detection tool that they can use during criminal investigations.

The Korean National Police Agency (KNPA) announced on March 5, 2024 to South Korean press agency Yonhap that its National Office of Investigation (NOI) will deploy new software designed to detect whether video clips or image files have been manipulated using deepfake techniques.

Unlike most existing AI detection tools, traditionally trained on Western-based data, the model behind this new software was trained on 5.2 million pieces of data from 5400 Koreans and related figures. It adopts “the newest AI model to respond to new types of hoax videos that were not pretrained,” KNPA said.

Major technology companies signed a pact Friday to voluntarily adopt “reasonable precautions” to prevent artificial intelligence tools from being used to disrupt democratic elections around the world.

Executives from Adobe, Amazon, Google, IBM, Meta, Microsoft, OpenAI and TikTok gathered at the Munich Security Conference to announce a new framework for how they respond to AI-generated deepfakes that deliberately trick voters. Twelve other companies — including Elon Musk’s X — are also signing on to the accord.

“Everybody recognizes that no one tech company, no one government, no one civil society organization is able to deal with the advent of this technology and its possible nefarious use on their own,” said Nick Clegg, president of global affairs for Meta, the parent company of Facebook and Instagram, in an interview ahead of the summit.

Technology giants are planning a new industry “accord” to fight back against “deceptive artificial intelligence election content” that is threatening the integrity of major democratic elections across the world this year.

A draft Tech Accord, seen by POLITICO, showed technology companies want to work together to create tools like watermarks and detection techniques to spot, label and debunk “deepfake” AI-manipulated images and audio of public figures. The pledge also includes commitments to open up more about how the firms are fighting AI-generated disinformation on their platforms.

“We affirm that the protection of electoral integrity and public trust is a shared responsibility and a common good that transcends partisan interests and national borders,” the draft reads.

 CARA HUNTER, A NORTHERN IRISH POLITICIAN, WAS ONLY WEEKS away from the country’s 2022 legislative elections when she received a WhatsApp message from someone she didn’t know. The man quickly asked her if she was the woman in an explicit video — a 40-second clip that he shared with the then-24-year-old. Opening the video, Hunter was confronted with an AI-generated deepfake video of herself performing graphic sexual acts. Within days, the false clip had gone viral, and the Northern Irishwoman was bombarded with direct messages from men around the world with increasingly sexual and violent messages.

“It was a campaign to undermine me politically,” Hunter, who won her 2022 Northern Ireland Assembly seat by just a few votes, told me. “They had felt that, because they saw an explicit of someone who looked like me, it was OK to send me nasty messages. It has left a tarnished perception of me that I can’t control. I’ll have to pay for the repercussions of this for the rest of my life.”

Before we get into this, let’s be very clear: Deepfake pornography, unfortunately, is not new. It’s been around for almost a decade and almost entirely targets women. It regained public attention after Taylor Swift became the latest victim when AI-generated graphic images of her were created, mostly via a 4Chan message board, and then shared widely on X, formerly known as Twitter. I also don’t want to mansplain what every woman reading this already knows. This is all about power. Power to demean women; power to control how women can participate in public life; power to silence voices that men (and it’s almost entirely men) believe are not worthy. Don’t take my word for it. There’s been some great reporting on this, for years. (Herehere and here.) I could find no examples of male politicians targeted with such sexual abuse.
