DEEP FAKE, A BLESSING OR DISGUISE?

 

 

deepfake

Deepfake may be a new and emerging tech that consists of AI-generated videos of an individual edited with another person’s voice/face. It’s applications came call at October 2019. However, the amount of users rapidly increased within the recent pandemic up to 300 percent.

Deepfake tech can convincingly be very harmful since anyone can have access thereto. Also, it is often wont to tarnish anyone’s reputation could also be because of political or personal reasons. This tech is already in use to form fake  material that too without the consent of another person.

One thing that’s a matter of great concern is that with such advanced technology at everyone’s hands it are often pretty difficult for anyone to differentiate between the important and therefore the fake videos.

According to the researchers at Sungkyunkwan University in Suwon, South Korea , even the appliance programming interface (API) from Amazon and Microsoft are often deceived with the Deepfake generated videos. It had been also said that the API at Microsoft’s Azure cognitive services had been double-crossed by the Deepfake generated content by almost 78 percent.

Till now it’s quite difficult for Microsoft and Amazon’s APIs to differentiate the deepfake impersonator from the real content. Researchers will handle this by creating suitable defense mechanisms and better designing web-based application programming interfaces.

The researchers are continuously performing on finding the weak points of the deepfake detection AI. Up till now, 5 data sets have been specimen for the commercial face recognition API.  Researchers contributed to two of them and public made the other three . And it’s found that the general public figures whose pictures are videos are in bulk on the social media are more susceptible to get created also as in a simple way.

MyHeritage

Deepfakes already possess a nasty reputation as they manipulate the person, but can we calculate it for a few benefits?How wouldn’t it feel if you’ll see your great grandparent blinking and smiling in one among her old photographs? It’ll creep you out, no doubt, but will it also cause you to nostalgic? Well consistent with MyHeritage, you would possibly be nostalgic.

The genealogy startup MyHeritage has recently introduced a replacement feature called Deep Nostalgia that permits users to animate the faces in family photos. Consistent with MyHeritage, users animated over 1 million photos within the first 48 hours alone.

One among their blogs says, “Users have responded with wonder and emotion. Some were in awe to ascertain ancestors they’d never met. Some from over 100 years ago.Move, blink, and smile. While others were in tears witnessing their lost loved ones in motion after numerous years with only still photos to recollect them by.”

The website in its FAQs admitted that it’s possible for people to seek out these videos creepy. Although, the feature has now become the new trend and lots of are using it to witness their long-lost loved ones moving.

According to MyHeritage, they licensed the technology from D-ID, an Israeli company specializing in video reenactment using deep learning.

The startup revealed that they didn’t include speech to stop abuse of this technology to make deep fakes of living people. Although, they need already created a promotional video with speech and audio wherein they reanimated Lincoln . Is it to not a deepfake?

Deepfake technology has garnered such a lot negative attention and concern with regards to spreading fake news. Thus, we need to set boundaries  to make a decision whether it’s a threat or not.

How do Deepfakes work?

Deepfake uses AI-based technology to control images, audio, and video to form them seem authentic and real. This technology uses machine learning systems to synthesize videos and audio quickly at a minimal cost. Neural networks like Generative Adversarial Networks (GANs) are wont to train data sets with real footage to form them understand a person’s actual voice, behavior, and expressions.

It uses two separate machine learning models . One to coach on the provided datasets and fabricate images. The other for monitoring these fabrications and grade the synthesis. Lately users create deepfakes by both AI and non-AI-algorithms and don’t involve GANs.

Deepfakes are a threat in some ways just like the use of deepfake audios in money extortion, fraudsters targeting celebrities and politicians to spread fake news, creating non-consensual private videos, etc.

Back in 2019, a video of Nancy Pelosi, speaker at the us House of Representatives, took rounds on social media. Wherein she was speaking unusually slow and high pitched. That video was not real.

The purpose of this video was to shed negative light on her and this is often not the first-ever incident. There are many such incidents where manipulated videos went rounds.

Deepfake threat to businesses

However, new sorts of deepfake have now entered the frame with the aim of committing fraud. Indeed, the utilization of deepfake video and audio technologies could become a serious cyberthreat to businesses within subsequent few years, cyber-risk analytics firm CyberCube warns during a recent report.

“Imagine a scenario during which a video of Elon Musk giving trading tips goes viral. Only it’s not the important Elon Musk. Or an official announces a replacement policy during a video clip. But once more it’s not real”. Says Darren Thomson, head of cybersecurity strategy at CyberCube.

“We’ve already seen these deepfake videos utilized in political campaigns; it’s only a matter of your time before criminals apply an equivalent technique to businesses and wealthy private individuals. It might be as simple as a faked voicemail from a senior manager instructing staff to form a fraudulent payment or move funds to an account found out by a hacker.”

 

 

Deepfakes in businesses

In fact, such attacks are already beginning to occur. In one high-profile example in 2019, fraudsters used voice-generating AI software to fake a call from the chief executive of a German firm to his counterpart at a UK subsidiary. Fooled, the united kingdom chief executive duly authorised a payment of $243,000 to the scammers.

“What we’re seeing is these sorts of attacks occuring more and more. They’re not overly sophisticated, but the quantity of cash they’re trying to swindle is sort of high”. Says Bharat Mistry, technical director, UK and Ireland, at Trend Micro.

“I was with a customer within the UK and he told me he’d received a voicemail, and it had been the chief information officer asking him to try to to something. Yet he knew the CIO of the organisation was on holiday and it was not possible. There was no distinguishing factor, so you’ll see how clever it’s .”

Attacks like this follow an equivalent pattern as traditional business email compromise scams, but with vastly more sophistication.

“We’ve seen of these cloud technologies, things like analytics, machine-learning and AI.  And deepfakes are just an extension of that technology, using the tech in an abusive manner,” says Mistry.

Fraudulent bank accounts

Another emerging sort of deepfake fraud is that the fraudulent creation of accounts, whether or not they are bank accounts, exchange dealing accounts or share dealing accounts. These are often employed by organised crime for the needs of cash laundering. And with the arrival of the coronavirus pandemic, what was previously a gradual shift to remote account creation has now been massively accelerated, along side the potential for fraud.

Setting up an account remotely generally involves a two-step process. First, providing a scan of an identity document then presenting a selfie. The applicant records a video during which they recite words or numbers, or perhaps through a brief video interview with an agent to generate a selfie.

How organisations are fighting back

The first line of defence against impersonation attacks, says Mistry, is to form sure all standard security procedures are in place and to create in automatic checks.

“If they’re posing for a money transfer or to vary something or to amend something on a document, then it should get verification through another channel,” he says.

Financial institutions, meanwhile, are turning to more sophisticated methods of detecting deepfakes.

Passive liveness detection uses algorithms to detect signs in a picture that it’s not genuine by examining textures, edges and therefore the like.

Increasingly, though, active detection is in use , introducing unpredictable information the deepfaker can’t predict and can’t effectively spoof.

Any Positives By Chance?

Deepfake technology uses AI to simulate human actions to make videos and that they are infamous for spreading misinformation. However, some fields can actually enjoy deepfakes. The movie industry can leverage deepfake technology to edit videos without reshooting them and also recreate actors who gave up the ghost on the screen.

Training and academic videos can leverage deepfakes to enable virtual materials without human intervention. Deepfake technology has other benefits and thus can impact positively if used within ethical grounds.

For example, the new feature launched by MyHeritage are often appealing for several people but until it crosses the boundaries. If it creates misinformation in any way it’d come under strict scrutiny. There are already regulations on deepfake technology and lots of legislations are getting to criminalize non-consensual deepfakes.
