Facebook Shares the Results of its First Deepfake Detection Challenge

Published

on

With various politically-affiliated groups already using digital platforms to manipulate and influence voters, the rise of deepfakes is a serious concern, and could pose a major threat to democracy as we know it.

That’s why all the major platforms are working to develop systems to detect digitally altered videos, in order to catch them before they can spread. Twitter launched its ‘Manipulated Media’ policy back in February for this purpose, while Facebook has been looking at ways to advance its own detection models. In line with this, back in September, The Social Network issued a challenge to academic teams to come up with better deepfake detection models which could be used to weed out these videos.

And this week, Facebook has shared the results of its first Deepfake Detection Challenge.

As explained by Facebook:

The DFDC launched last December, and 2,114 participants submitted more than 35,000 models to the competition. Now that the challenge has concluded, we are sharing details on the results and working with the winners to help them release code for the top-performing detection models.”

This is a key point – Facebook, upon working with the winning teams, is looking to share the codebase for each of the winning models, while it’s also planning to open source the datasets used, in order to help advance research into deepfakes more broadly.

So how good were the winning models?

Facebook Deepfake Detection Challenge

The best performing detection models, from the thousands submitted, saw detection rates above 82%. Which is impressive – but that was based on the training set provided, which the researchers could study and refine specifically, focused on those examples.

In order to determine the true accuracy of these systems, Facebook also tested the models on a ‘black box’  dataset of 10,000 video clips which the participants had not previously seen and had no access to before submitting their code. That altered the final results significantly.

The highest-performing entrant was a model entered by Selim Seferbekov. It achieved an average precision of 65.18% against the black box data set. Using the public data set, this model had been ranked fourth. Similarly, the other winning models, which were second through fifth when tested against the black box environment, also ranked lower on the public leaderboard. (They were 37th, 6th, 10th and 17th, respectively.)”

As you can see, the results changed a lot when they were applied to videos that the researchers could not train for specifically. That likely shows that there’s still a long way to go in establishing a truly accurate deepfake detection system – though a 65% detection rate is still significant, and would likely help to flag many potential concerns within the posting process.

Ideally, however, Facebook can get this number higher, and develop a better system for determining digitally altered videos before they’re shared. Because as we’ve seen, once a video is uploaded online, the fact that it’s determined to be fake or edited at a later stage is often too late to stop the damage being caused.

Already, within this US Presidential Election cycle, we’ve seen several examples of videos being edited or changed in order to emphasize certain elements. There was the controversial Nancy Pelosi video, in which Pelosi appeared to be slurring her words, the Michael Bloomberg video where he pressed other candidates on their business credentials during a debate, and the Joe Biden clip which had been edited to show Biden saying that people should vote for Donald Trump.

These videos were not advanced deepfakes, they all used fairly basic editing techniques. But each of them sparked significant debate, despite them being heavily edited, and proven to be so. Even when they were revealed to be edited, the debates carried on. You can only imagine the damage that a convincing enough deepfake could do within that same process.

And we are indeed likely to find out just how much damage deepfakes can do. As the 2020 US Election race heats up, it seems increasingly likely that, at some stage, a deepfake video of some kind will come into play. 

How will that change the race? How will it alter voter behavior? Can digital platforms detect and eliminate such before it takes hold?

It could just be that in the wake of the election, a deepfake video might be the central focus, much like Cambridge Analytica became the target after 2016. Facebook’s working to avoid that outcome, and it could end up bring a crucial effort.

92-year-old Malawian music legend finds fame on TikTok

92-year-old Malawian music legend finds fame on TikTok


Fame at 92: Malawian music legend Giddes Chalamanda has notched up millions of views on TikTok – Copyright AFP Bertha WANG

Jack McBrams

At 92, Giddes Chalamanda has no idea what TikTok is. He doesn’t even own a smartphone.

And yet the Malawian music legend has become a social media star, with his song “Linny Hoo” garnering over 80 million views on the video-sharing platform and spawning mashups and remixes from South Africa to the Philippines.

“They come and show me the videos on their phones, but I have no idea how it works,” Chalamanda told AFP at his home on the edge of a macadamia plantation, about 20 kilometres (12 miles) from Malawi’s main city Blantyre.

“But I love the fact that people are enjoying themselves and that my talent is getting the right attention,” he said, speaking in Chewa.

Despite his grey hair and slight stoop, the nonagenarian singer and guitarist, who has been a constant presence on the Malawian music scene for seven decades, displays a youthful exuberance as he sits chatting with a group of young fans.

He first recorded “Linny”, an ode to one of his daughters, in 2000.

But global acclaim only came two decades later when Patience Namadingo, a young gospel artist, teamed up with Chalamanda to record a reggae remix of “Linny” titled “Linny Hoo”.

The black-and-white video of the recording shows a smiling, gap-toothed Chalamanda, nattily dressed in a white shirt and V-neck sweater, jamming with Namadingo under a tree outside his home, with a group of neighbours looking on.

The video went viral after it was posted on YouTube, where it racked up more than 6.9 million views. Then late last year, it landed on TikTok and toured the globe.

Chalamanda only learned of the song’s sensational social media popularity from his children and their friends.

Since then he and Namadingo have recorded remixes of several others of his best-known tracks.

His daughter Linny’s 16-year-old son Stepson Austin told AFP that he was proud of his grandfather’s longevity.

“It is good that he has lived long enough to see this day,” said the youngster, who himself aspires to become a hip-hop artist.

Born in Chiradzulu, a small town in southern Malawi, Chalamanda won fame in his homeland with lilting songs such as “Buffalo Soldier” in which he dreams of visiting America and “Napolo”.

Over the past decade, he has collaborated with several younger musicians and still performs across the country.

– ‘Dance around the world’ –

On TikTok, DJs and ordinary fans have created their own remixes as part of a #LinnyHooChallenge.

“When his music starts playing in a club or at a festival, everyone gets the urge to dance. That is how appealing it is,” musician and long-time collaborator Davis Njobvu told AFP.

“The fact that he has been there long enough to work with the young ones is special.”

South Africa-based music producer Joe Machingura attributed the global appeal of a song recorded in Chewa, one of Malawi’s most widely-spoken languages, to the sentiments underlying it.

“The old man sang with so much passion, it connects with whoever listens to it,” he said, adding: “It speaks to your soul.”

Chalamanda, a twice-married father of 14 children, only seven of whom, including Linny, are still alive, said he has no idea how to secure royalties for the TikTok plays.

Chalamanda and his wife hope to benefit financially from his new-found stardom.

“I am just surprised that despite the popularity of the song, there is nothing for me,” he said. “While I am excited that I have made people dance all around the world, there should be some gain for me. I need the money.”

His manager Pemphero Mphande told AFP that he was looking into the issue and the Copyright Society of Malawi said it was ready to assist.

Arts curator Tammy Mbendera of the Festival Institute in Malawi credited platforms like TikTok with creating new opportunities for African talent.

“With songs from our past especially, they were written with such profoundness that they still can resonate today,” she said.

“All one has to do really, is get the chance to experience it, to acknowledge its significance. I think that’s what happened here.”
