FOR PUBLISHERS
Hashproof signs your images and video with verifiable C2PA provenance, keeps image attribution attached through syndication, and gives readers a trust signal they can check for themselves. The same substrate camera makers and wire services already build on.
Three gaps between how media is made and how it is trusted.
Fabricated images and cloned voices now circulate faster than corrections. When readers cannot tell a real photograph from a generated one, the credibility of everything you publish takes the discount, including the work that is genuine.
A photo licensed to a wire service, re-cropped by a downstream outlet, and re-posted on social media loses its byline within two hops. Photographers go uncredited and the original publisher loses the provenance trail.
When an image is later found to be miscaptioned or manipulated, there is no mechanism to attach that finding to every copy already in circulation. The record stays wrong in most places it appears.
Four primitives, one HTTP API, across every media type you publish.
Issue a C2PA manifest the moment an asset enters your CMS, or integrate at the camera and ingest the manifest already present. Either way, the manifest is stored in the Hashproof registry, resolvable and verifiable through the API.
Soft-binding resolution reconnects a re-encoded or cropped image to its original manifest, so a syndicated copy still resolves to the photographer and the originating desk. Credit follows the asset, not the file path.
Verification returns validation detail and trust-list status in one response. Surface a content-credentials badge that any reader, platform, or fact-checker can check through the public verify endpoint.
C2PA records the chain of edits an asset went through: color correction, cropping, compositing. Readers see what was changed between capture and publication, which is often the question that actually matters.
Four touch points across the life of an asset, from ingest to correction. Your CMS, DAM, and editorial systems stay in place.
01
Your CMS or DAM POSTs each image and video to the signing endpoint at upload. Every asset is signed fresh with a managed manifest; manifests already embedded in a file are left in place but not parsed or extended.
02
Manifests for published assets live in the Hashproof registry, resolvable and verifiable through the API. The verify endpoint powers a content-credentials badge on the page.
03
When a partner re-publishes a transformed image copy, soft-binding resolution maps it back to your original manifest. Attribution and licensing terms stay attached across outlets.
04
If an asset is later found to be misattributed, you can sign and store a corrected manifest; resolution returns matching manifests ranked by similarity.
Infrastructure, not a badge program. The interoperability is the point.
C2PA is supported by major camera makers, wire services, and platforms. Manifests their tools embed verify through Hashproof, and the records you issue follow the same C2PA data model. You are joining an interoperable graph, not adopting a proprietary badge.
Hashproof signs and verifies. It does not rank, moderate, or editorialize. The provenance layer is a fact about the asset; what you do with it stays an editorial decision.
Photo desk, video team, and syndication all use the same endpoints. No per-format vendor sprawl, no separate system for each media type.
