Deep tech to stop deepfakes


The digital watermark b<>com developed adds a unique, indelible, and invisible digital mark to video content or images. Among its applications, video authentication ensures that no deepfakes are present and that the content offered is the original. Gaëtan Le Guelvouit, cybersecurity expert at b<>com, looks at b<>com *Tag* and its advantages in detecting deepfakes.

Deepfakes attack!

Remember when a company was swindled out of 26 million dollars by a deepfake of its CFO? Or, more recently, when the Bombay Stock Exchange boss's deepfake gave great investment advice? Or when someone uses celebrities' faces to promote a mobile casino application? These are just a few examples of the damage that deepfakes can cause. Scams of all kinds, as well as manipulation of information and even influencing public opinion, are part of the list.

Digital watermarking to the rescue

In the race between technologies for generating deepfakes - which the human eye can hardly differentiate from reality - and those for detecting deepfakes, digital watermarking is a formidable tool. It can certify that video content has not been altered (in particular, no malicious processing has been added), and that it is perfectly authentic.

Guaranteeing image integrity

"This is one of the possible applications of b<>com *Tag*, our digital video watermarking solution. It verifies that all the images in a video are present and intact and that no faces or elements have been replaced or erased. It can be used anywhere in the content production chain, from camera capture to broadcast. That's why it's just as well suited to camera manufacturers, who can include it directly in their devices, as well as to editing software publishers, transcoder manufacturers, or SaaS solutions", explains Gaëtan Le Guelvouit, a cybersecurity expert at b<>com.

b<>com *Tag* operates as a stand-alone system, making it easy to adopt and integrate.

"This solution requires no connection to an external server: digital tattooing requires no exchange of information or sending of metadata to the cloud. *Tag* operates autonomously, which greatly simplifies its adoption and integration. All this with minimal added power consumption. It has already proved its worth in anti-piracy applications: our member Viaccess-Orca has adopted it to combat the piracy of video streams from live sporting events."

For the first time, b<>com will demonstrate b<>com *Tag* on its stand at IBC, France Pavilion, stand no. 2.C20.
