Chapter IV of this regulation is dedicated to the obligation of transparency, meaning that providers and deployers of systems must report content produced or modified by AI (Article 50, paragraphs 2 and 4). It also specifies the form in which this information must be available, referring to results &#8220;marked in a machine-readable format&#8221; and information &#8220;provided to the data subjects in a clear and distinct manner no later than the time of the first interaction or first exposure&#8221; (Article 50, paragraph 5). The information must therefore be, on the one hand, readable and displayable by software and, on the other hand, readable by a human as soon as the content in question is displayed.<\/span><\/p>\n<p><span dir=\"auto\">In 2021, six companies from the media, electronics, and digital document authentication sectors (Adobe, Arm, the BBC, Intel, Microsoft, and Truepic) founded the Coalition for Content Provenance and Authenticity (C2PA). Their goal is to restore market trust in AI by developing a common method for marking digital files. C2PA promises users to display how and when the photo, video, audio, or text they are viewing was produced, what software was used to modify it, and the nature of those modifications.<\/span><\/p>\n<p><span dir=\"auto\">The principle is based on metadata, which is information of all kinds about a piece of content. For example, for a digital photo: the date, the photographer, and the location of the shot, the type of camera used, and the name and version of the editing software. This metadata is generated by content publishers&#8217; applications, cameras, or other devices, whether or not they rely on AI. This metadata, embedded in the files, is updated with each new modification to the content, even if it is made with different software. C2PA&#8217;s solution relies on Content Credentials, a standard and open metadata format, the specifications of which are published on the\u00a0<\/span><a href=\"https:\/\/spec.c2pa.org\/specifications\/specifications\/2.3\/index.html\"><em><span dir=\"auto\">C2pa.org<\/span><\/em><\/a><span dir=\"auto\">\u00a0website . To resist falsification, this data is encrypted using a digital signature system that guarantees its origin.<\/span><\/p>\n<h4><strong><span dir=\"auto\">The coalition is underway<\/span><\/strong><\/h4>\n<p><span dir=\"auto\">But to be effective, the system must be adopted by as many publishers and content producers as possible in order to marginalize files lacking this authentication metadata (much like a consumer would avoid a product that doesn&#8217;t display a Nutri-Score). Once widely disseminated, Content Credentials will also act as a transparency label.<\/span><\/p>\n<p><span dir=\"auto\">The goal is to attract as many influential companies as possible to the coalition, and the results are promising. In 2022, one year after its creation, C2PA had 200 international members. In February 2024, Meta, OpenAI, and Google joined the coalition\u2026 and became members of its steering committee. Among media and communications groups, Publicis, Springer Nature, Reuters, RAI,\u00a0<\/span><em><span dir=\"auto\">Die Zeit<\/span><\/em><span dir=\"auto\">\u00a0, and\u00a0<\/span><em><span dir=\"auto\">The Wall Street Journal<\/span><\/em><span dir=\"auto\">\u00a0followed the BBC&#8217;s lead, and at the end of 2025, France T\u00e9l\u00e9visions announced it had launched its trials integrating the standard for authenticating its newspapers. By 2025, C2PA boasted a community of over\u00a0<\/span><a href=\"https:\/\/contentauthenticity.org\/blog\/5000-members-building-momentum-for-a-more-trustworthy-digital-world\"><span dir=\"auto\">5,000 members<\/span><\/a><span dir=\"auto\">\u00a0.<\/span><\/p>\n<h4><strong><span dir=\"auto\">The first Content Credentials applications are on the market<\/span><\/strong><\/h4>\n<p><span dir=\"auto\">Since 2024, Adobe has been rolling out Content Credentials in its image processing applications, including the popular Photoshop and the Firefly text-to-image generator. In November 2025, OpenAI announced that content credentials would be automatically applied to all images generated by DALL-E 3, GPT-image-1, and the SORA 2 generative audio and video model.<\/span><\/p>\n<p><span dir=\"auto\">The &#8220;inspection tool&#8221; war is on. In 2026, on Pixel10 smartphones running Android 8, the Google Photos app displays the &#8220;Content Credentials pin,&#8221; &#8220;Cr,&#8221; indicating the presence of authentication metadata in downloaded images. The\u00a0<\/span><em><span dir=\"auto\">Adobe Content Authenticity<\/span><\/em><span dir=\"auto\">\u00a0platform is functional in beta. A Lense verification extension, exclusively for the Chrome browser, is available on app stores.<\/span><\/p>\n<p><span dir=\"auto\">At the beginning of 2026, the tests I performed to illustrate this article were rather laborious: images containing the valuable metadata are still rare on the web. It was therefore necessary to generate a test image with DALL-E 3 (integrated into ChatGPT), which only produces C2PA metadata when explicitly requested. However, Adobe&#8217;s inspection tool then valiantly displayed the metadata and detected the OpenAI signature. On the other hand, the test performed with the Lense extension for Chrome failed.<\/span><\/p>\n<p><em><strong>Author Bio:<\/strong> Claire Scopsi is Professor of Information and Documentation Sciences at the National Conservatory of Arts and Crafts (CNAM)<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Just a few years ago, we were amused by the completely fanciful photos generated by AI, but today it&#8217;s becoming increasingly difficult to distinguish the real from the fake with the naked eye.
