Overview
G&L enables you to achieve C2PA compliance
In an era where digital content can be effortlessly created and manipulated, distinguishing between genuine and fake media has never been more vital. Whether you’re a broadcaster, news agency, or content creator, the risk of manipulated media is ever-present. The Coalition for Content Provenance and Authenticity (C2PA) addresses this by developing technical standards for certifying the source of media content.
A clear path to implementing C2PA standards
Elevate your media’s authenticity with cryptographic verification, expertly integrated by G&L Systemhaus for seamless implementation.
Watch G&L's CEO Alexander Leschinsky in this Streaming Media Europe video interview as he delves into why and how C2PA can protect your content and its current limitations.
Key features
Signing, Verification & Display of Content Credentials
"It has always been G&L's focus to take international standards and bring them into production life. With C2PA, we are now supporting an initiative that goes well beyond our traditional realm of content distribution."

Content Integrity Across Platforms
When distributing content across social media and digital platforms, metadata can be stripped during the process. C2PA’s integration of digital watermarking ensures that its provenance remains intact.
How C2PA standards ensure media credibility and transparency
Partnerships
G&L collaborates closely with fellow C2PA members, actively contributing to the working groups.
Technical specifications
Storage of Manifests
Internal Metadata
C2PA manifests are embedded directly into media files using formats like JUMBF (JPEG Universal Metadata Box Format) or other media-specific formats (e.g., MP4 for video). This ensures that the metadata remains attached to the media file throughout its lifecycle, offering robust protection against metadata being stripped or altered.
Storage of Manifests
External Metadata
C2PA manifests are stored externally, providing flexibility for workflows where embedding metadata internally may not be feasible. In this case, the metadata travels with the file as a separate, associated component.
Hard Bindings
The standard supports strong, cryptographic links that uniquely identify the asset or portions of it.
Soft Bindings
The standard supports using perceptual hashes or content fingerprints to allow derived or modified versions to retain provenance data.
Watermark Action: A signal that a watermark has been embedded in the asset, allowing tools to recognize and recover the original provenance data. Standardized Algorithms: C2PA includes support for various watermarking algorithms to ensure interoperability across platforms and vendors. Soft Binding API: An API that allows platforms to recover lost manifests by detecting the embedded watermark, thus maintaining content authenticity even when the manifest is no longer present.
