As fake images become more convincing and widespread, camera makers are fighting back with new technology that can verify the authenticity of photos. Nikon, Sony Group, and Canon are working on embedding digital signatures in their cameras, which will act as proof of origin and integrity for the images.
As Nikkei Assiareports, digital signatures will contain information such as the date, time, location, and photographer of the image and will be resistant to tampering. This will help photojournalists and other professionals who need to ensure the credibility of their work. Nikon will offer this feature in its mirrorless cameras, while Sony and Canon will also incorporate it in their professional-grade mirrorless SLR cameras.

Verify: A global standard for digital signatures
The three camera giants have agreed on a global standard for digital signatures, which will make them compatible with a web-based tool called Verify. This tool, launched by an alliance of global news organizations, technology companies, and camera makers, will allow anyone to check the credentials of an image for free. Verify will display the relevant information if an image has a digital signature. If artificial intelligence creates or alters an image, Verify will flag it as having "No Content Credentials."
The need for such technology is evident, as deepfakes of prominent figures like former US President Donald Trump and Japanese Prime Minister Fumio Kishida have gone viral this year, raising questions about the trustworthiness of online content. Moreover, China's Tsinghua University researchers have developed a new generative AI technology called a latent consistency model, which can produce about 700,000 images daily.
How others are also joining the fight
Other technology companies are also joining the battle against fake images. Google has released a tool that adds invisible digital watermarks to AI-generated pictures, which can be detected by another tool. Intel has developed technology that can analyze the skin color changes of subjects in images, which indicate the blood flow under their skin, and use that to determine the image's authenticity. Hitachi is working on technology to prevent online identity fraud by verifying user images.
The new camera technology is expected to be available by 2024. Sony will release it in the spring of 2024, and Canon will follow suit later that year. Sony is also considering adding the feature to videos, and Canon is developing a similar video technology. Canon also released an image management app to tell whether humans take images.
Sony will also promote the adoption of the technology among other media outlets and has already field-tested it with The Associated Pressin October. Canon has partnered with Thomson Reutersand the Starling Lab for Data Integrity, an institute co-founded by Stanford University and the University of Southern California, to develop the technology.
The camera makers hope their technology will help restore the trust and confidence in the images that shape our perception of the world.
