Nikon, Sony Group and Canon are developing camera technology that embeds digital signatures in images so that they can be distinguished from increasingly sophisticated fakes. From a report: Nikon will offer mirrorless cameras with authentication technology for photojournalists and other professionals. The tamper-resistant digital signatures will include such information as date, time, location and photographer. Such efforts come as ever-more-realistic fakes appear, testing the judgment of content producers and users alike.
An alliance of global news organizations, technology companies and camera makers has launched a web-based tool called Verify for checking images free of charge. If an image has a digital signature, the site displays date, location and other credentials. The digital signatures now share a global standard used by Nikon, Sony and Canon. Japanese companies control around 90% of the global camera market. If an image has been created with artificial intelligence or tampered with, the Verify tool flags it as having “No Content Credentials.”
Maybe Computer Science should be in the College of Theology.
