Google fights misinformation: C2PA arrives on Pixel and Photos for AI image recognition.

Redazione RHC : 12 September 2025 07:59

Google announced that it will integrate C2PA Content Credentials technology into the Pixel 10 camera app and Google Photos to help users distinguish authentic images from those created or modified by artificial intelligence.

Google noted that the problem of labeling synthetic content has become much more acute in recent years, as traditional approaches are virtually ineffective and leave room for different interpretations and distortions of information.

On the latest Pixel 10 smartphones, every JPEG photo will automatically receive Content Credentials, which contain information about how the photo was created. photos.

Vuoi diventare un esperto del Dark Web e della Cyber Threat Intelligence (CTI)?

Stiamo per avviare il corso intermedio in modalità "Live Class" del corso "Dark Web & Cyber Threat Intelligence". A differenza dei corsi in e-learning, disponibili online sulla nostra piattaforma con lezioni pre-registrate, i corsi in Live Class offrono un’esperienza formativa interattiva e coinvolgente. Condotti dal professor Pietro Melillo, le lezioni si svolgono online in tempo reale, permettendo ai partecipanti di interagire direttamente con il docente e approfondire i contenuti in modo personalizzato. Questi corsi, ideali per aziende, consentono di sviluppare competenze mirate, affrontare casi pratici e personalizzare il percorso formativo in base alle esigenze specifiche del team, garantendo un apprendimento efficace e immediatamente applicabile.

“Content credentials contain a rich set of information about how media files (images, videos, or audio files) were created, protected by the same digital signature technology that has kept online transactions and mobile apps secure for decades,” Google explains. “This gives users the ability to identify content created (or modified) by AI, promoting greater transparency and trust in generative AI.”

So, if a user edits the original image with or without AI, Google Photos will add the new information to the Content Credentials, keeping a history of all changes.

The company writes that the system works autonomously, is completely protected from external interference and does not threaten user anonymity, while maintaining the possibility of verification. Google describes several layers of security and integrity built into Content Credentials, designed to make the system more secure and protected from unauthorized access:

A cryptographic signature that invalidates the digital signature when metadata is modified;
Tamper-proof key storage: All cryptographic keys are generated and stored in the Android StrongBox within the Titan M2;
Android Key Attestation, which allows Google’s C2PA CAs to verify the authenticity of both the hardware and the requesting app. data;
One-time keys for each image: Each photo is signed with a unique cryptographic key that is never reused, which should preserve user privacy and anonymity;
Trusted timestamps, backed by a secure internal device clock powered by Tensor, allowing Pixel devices to create verifiable timestamps even when offline.

For now, the Content Credentials system will only be available on Pixel 10 devices, but Google representatives write that they intend to extend it to other Android devices in the future. However, the company has not yet indicated specific dates or times.

The company calls on all industry stakeholders to go beyond simplifying AI-based content labeling and adopt content credentials, stressing that the fight against misinformation and deepfakes requires the widespread adoption of content verification technologies across the industry.
