DigiCert has announced the availability of Content Trust Manager, a new product within its DigiCert ONE platform aimed at helping organisations prove the origin and integrity of digital media using cryptographic credentials.
The release comes as synthetic and AI-generated media proliferate, making it harder for organisations and audiences to distinguish authentic content from altered or generated assets. DigiCert said traditional approaches such as metadata and platform-level signals can be modified, removed or fail to persist across systems, driving interest in cryptographic approaches that provide verifiable proof of authenticity.
“Trust in digital content is under pressure as AI makes it easier than ever to create and alter images, video, and other media,” said Deepika Chauhan, chief product officer at DigiCert. “What’s needed is a consistent, scalable way to attach trust directly to content itself. Content Trust Manager brings together DigiCert’s global PKI and C2PA’s open standards to attach trusted, tamper-evident credentials to digital media.”
DigiCert said the managed service is intended to let enterprises sign and verify content using its public key infrastructure (PKI), and integrate into existing workflows via APIs. The company said it supports certificate issuance, key management and signing, and uses the Coalition for Content Provenance and Authenticity (C2PA) standard, which has been adopted by companies including Adobe, Microsoft and Google.
The company said provenance credentials are embedded into media files so they can persist as content is shared, edited or redistributed. It said the product supports C2PA-compliant signing workflows for images, video and other digital assets, independently verifiable signatures for origin and authorship, API-based integrations, and DigiCert-issued certificates and timestamping.
“The growth of AI-generated content requires organisations to prove authenticity to preserve and maintain trust,” said Jennifer Glenn, research director for IDC Security and Trust Group. “By embracing C2PA standards and the proven trust of PKI, organisations can build the cryptographic foundation needed to verify provenance and authenticity of digital content, ensuring credibility and trust with customers.”
DigiCert said Content Trust Manager is designed for global enterprises, media organisations and public sector entities, and incorporates capabilities from its previously announced Document Trust Manager to bring document and media authenticity into a single platform.
The company also pointed to a related approach for establishing trust at the moment of capture, using cryptographic signing and timestamping enabled by embedded C2PA certificates on trusted devices, delivered through DigiCert Device Trust Manager. DigiCert said this is intended for device manufacturers to embed signing and timestamping capabilities into devices such as cameras, microscopes and scanners.
