Major Camera Manufacturers Fight AI Fakes with Watermarking
As realistic AI-generated photos and videos become more prevalent online, tech firms and watchdog groups are working to develop tools to identify fake content. Watermarking computer-generated imagery has been proposed as a solution, but researchers have found that it can be easily removed using adversarial techniques. To address this issue, major camera manufacturers such as Nikon, Sony, and Canon are proposing a different approach: embedding watermarks in “real” photographs. These companies plan to include digital signatures in images taken directly from their high-end mirrorless cameras. The signatures will integrate key metadata, cryptographically certifying the digital origin of each photo.
The Purpose of Watermarking
The goal of this initiative is to provide photojournalists, media professionals, and artists with irrefutable proof of their images’ credibility. The tamper-resistant signatures will not disappear with edits and will help combat misinformation and fraudulent use of photos online. Additionally, the companies have collaborated on an open standard for interoperable digital signatures called “Verify.” This will allow people to check the authenticity of photos taken with compatible hardware for free.
Watermarking vs. Anti-Watermarking Techniques
While anti-watermarking techniques could potentially remove authenticity signatures from real photos, this is less problematic than removing watermarks from AI-generated fake images. If a watermark is stripped from an AI deepfake, it can pass as real more easily. However, if authentication signatures are hacked off real photos, the remaining image is still captured by a camera and does not originate from a generative model. Although it loses its cryptographic proof, the underlying content remains genuine.
The Risks and Importance of Watermarking
The primary risk in removing authenticity signatures from real photos is related to attribution and rights management, rather than the content’s veracity. OpenAI recently announced an AI-powered deepfake detector with 99% accuracy on images, but AI detectors still require constant upgrading to keep up with advancements in generative technology. With the surge in deepfake sophistication, the need to differentiate between real and fabricated content has become more acute, making watermarking an important tool in combating fake media.
Hot Take: Watermarking as a Crucial Defense Against AI Fakes
The rise of AI-generated fake content poses significant challenges for online platforms and users. Watermarking, particularly through embedding digital signatures in real photographs, offers a promising solution to verify the authenticity of images. By integrating metadata and cryptographic certification, major camera manufacturers like Nikon, Sony, and Canon are empowering photojournalists and media professionals with tools to combat misinformation and fraudulent use of photos online. While anti-watermarking techniques may pose some risks, watermarking remains crucial in distinguishing genuine content from AI-generated fakes. As technology continues to advance, the collaboration between camera manufacturers and the development of open standards for digital signatures will play a vital role in ensuring trust and credibility in visual media.
