Scroll through any popular social media app lately, and you’re bound to encounter a new wave of hyper-realistic filters. Far from being the cartoon puppy ears of yesterday, they’re AI-driven “diffusion” filters that can reshape your face in real time with uncanny precision. It’s no wonder everyone is trying them out. 

For platforms, the effect on engagement is nothing short of extraordinary. 

For example, when Snapchat released its viral gender-swap lens, 7 million people downloaded the app in just five days, a 133% spike over the prior week. Users eagerly shared their transformed selves. Some even used the female version of their face to catfish others on dating apps. 

More recently, TikTok’s “Bold Glamour” beauty filter exploded onto the scene. This filter uses AI to contour your face, plump your lips, and smooth your skin, essentially applying a full virtual makeover that sticks seamlessly as you move. With Hollywood-like results, Bold Glamour captivated users so much it was used in over 16 million videos in just one month. People tugged at their faces in disbelief, amazed at how no glitch or seam gave away the effect. 

Social platforms love this kind of activity. It keeps users scrolling, posting, and coming back for more. Even backlash can boost engagement. The controversy around unrealistic beauty standards only drew more eyes to TikTok.

It’s easy to see why companies are racing to deploy these AI effects. They make us feel more attractive or imaginative, and we reward that with our attention. Filtered videos are fun, addictive, and primed for virality. But what’s the cost to our privacy and sense of reality?

Deepfake Tech in Your Pocket Without Labels

The technology behind many of these new filters is akin to deepfake software once confined to research labs. In fact, experts say TikTok’s Bold Glamour likely uses generative AI (such as GANs or diffusion models) to redraw your face pixel by pixel based on learned ideals.

Put simply, the app is creating a new image of you that blends your features with AI-generated enhancements, essentially a friendly deepfake. 

What’s striking is how accessible this has become. “The capacity to believably manipulate yourself, and soon others, in videos has become commoditized… now everyone can do it for free and see how it works,” Halsey Burgund (MIT Open Documentary Lab technologist) noted about Bold Glamour’s tech. 

A process that used to require specialized skills can now be done by a teenager with a smartphone.

Privacy advocates and digital rights groups are worried this is normalizing deepfakes. Today it’s used for playful filters, but tomorrow the same capabilities could be used maliciously. When anyone can alter identities or realistically impersonate others with a tap of an app.

The Privacy Trade-Off: What Are We Giving Up?

1. Non-Consensual Explicit Content

Perhaps the most headline-grabbing application of this technology has been in adult content, where deepfake algorithms are being used to map faces onto explicit material. This has naturally sparked concern around consent. 

The thing is that these same generative tools are also powering more consensual experiences, such as open-ended AI chatbot platforms that allow conversations without filters that allow users to create private, customizable avatars and engage in simulated roleplay. When used ethically, they demonstrate how diffusion models can enable new types of AI companionship, intimacy, and expression, with the user having the full control over the key privacy factors.

That said, blurred lines still exist and just because someone shared a selfie on social media doesn’t mean it’s fair game for manipulation. As the tech gets more powerful and accessible, questions around responsible use grow even more urgent. 

2. Biometric Surveillance

Faces, irises, voices… these are the keys to our identity. If companies compile enough of this biometric data, it opens doors to mass surveillance and tracking. 

Just like the facial recognition cameras in public or voice identification tools, they thrive on large data sets. By cheerfully engaging with face filters, we are actually helping build those very databases. 

The ACLU and other privacy groups caution that what starts as entertainment could enable unconsented tracking. In one sobering example, researchers showed they could pull fingerprints from high-resolution photos of someone’s hand. 

3. Deception and Impersonation

While the Snapchat gender-swap lens was largely used in good humor, it didn’t take long for some to realize they could present as someone new entirely – say, a man appearing as a woman, and trick people online. 

That was a novelty case of catfishing. More malicious actors could use similar tech to impersonate specific individuals. 

We’re approaching an era where a bad actor could steal a few photos of you (perhaps from your public profiles) and use an AI filter or deepfake tool to appear as you in a video call, or leave a fake video message that actually never came from you. In a way, it’s high-tech identity theft.

From scammers trying to fool your family to political operatives mimicking public figures, the potential for harm is real. When seeing isn’t believing, anyone’s likeness can be appropriated and used in ways they never agreed to.

4. Data Retention & Ownership

Who owns that glammed-up selfie or face-swap video once you upload it? Often, it’s not you. Many apps claim broad rights to save and use your images. 

For example, a Chinese face-swapping app called Zao (which lets users put their face into movie scenes) grabbed worldwide attention because its terms gave the company “perpetual” rights to user photos, prompting an outcry. The backlash was so bad that China’s biggest messaging platform, WeChat, banned Zao-generated videos over deepfake and privacy. 

When you use a similar filter on Instagram or TikTok, do you know if that platform can later feed your face into an AI model or share it with partners? 

As Jennifer Gradecki, an associate professor of art and design at Northeastern University, put it, “They have your face data in perpetuity. They can do what they want with it, train whatever other algorithm…”.

A Reality Check for the Future

Today we’re at a crossroads. The same diffusion technology that makes us look effortlessly glamorous or drops us into fantasy worlds is also eroding the idea that images and videos can be trusted evidence. We’re being seduced by the mirror’s new reflection, as it chips away at our privacy behind the scenes.

It’s a thrilling and unsettling place to be. On one side, the fact that anyone can produce Hollywood-grade effects on a whim is thoroughly exciting. On the other, we’re normalizing a culture where consent and truth are afterthoughts, sacrificed at the altar of engagement. Unfortunately, the companies driving this trend have shown, time and again, that they will push the envelope if it keeps us glued to our screens. 

Enjoy the funny filters and viral challenges… there’s nothing wrong with a little digital fun. But let’s also ask the uncomfortable questions. 

• Do we know what we’re giving away when we tap that “Try now” button? 
• How will we feel about today’s viral filter a few years from now, when its privacy implications come home to roost? 
• If face data helped build a model snapshot last year, is any “delete my data” button today more theater than remedy?

It might be time to take a pause and demand that our tech tools respect our rights as much as they entertain us. Social media diffusion filters have undoubtedly raised engagement to new heights; now we must ensure they don’t quietly chip away at our right to privacy and control over our own identity in the digital age.
