The Digital Integrity Platform
Protecting the human integrity behind everything created digitally.
We care about human experience, thoughts, and interconnection. We build infrastructure so that journalists, artists, musicians, and software engineers can prove that they made this — and that it hasn't been corrupted along the way.

Turnkey C2PA
Content authenticity without the complexity
C2PA is the standard for proving content is real. We handle the cryptography, certificates, and infrastructure so you don't have to.
For Creators
Sign your work. Prove it's yours. One click to embed cryptographic proof that travels with your content forever.
For Studios
Sign at render-farm scale. Thousands of frames, multiple passes, automated pipelines. Prove your pixels without slowing down.
For Newsrooms
Publish with proof. Embed provenance in every image and video. Rebuild trust with readers who don't know what's real.
For Enterprises
Cloud or on-prem. API or dashboard. Certificate management included. Compliance-ready from day one.
Regulatory Landscape
Noosphere Delivers Compliance
| California SB 942 (Live) | EU AI Act Article 50 (Aug 2026) |
|---|---|
| ✓ Free detection tool required for GenAI content | ✓ Machine-readable disclosure on AI content |
| ✓ Manifest + latent disclosure options for users | ✓ Metadata must be interoperable and persistent |
| ✓ Licensees must preserve disclosure capabilities | ✓ Applies to any content distributed in EU |
| ✓ 96-hour revocation if disclosures stripped | ✓ Upstream suppliers inherit obligations |
✓ Forward compatible with emerging standards: Decentralized Identity and Verifiable Credentials
Why We Exist
Trust the internet you actually trust
Not the internet of dark algorithms and corporate interests. Our infrastructure empowers you to join, curate, and share trust ecosystems — where human creativity and ingenuity is preserved and rewarded.
Platform
Industrial-grade infrastructure. Human-friendly interface.
All the cryptographic complexity — hidden. All the power — accessible. Built for creators, not cryptographers.
Credential Management
Issue and manage DIDs, Verifiable Credentials, and X.509 certificates. Key lifecycle management with HSM support. Your identities, portable and under your control.
Signing Policies
Define policies for media, code, and workloads. C2PA for images and video. SLSA attestations for software. SPIFFE identities for agents. One policy engine across all artifact types.
Declarative Trust
Organizations publish trust policies that contribute to a shared graph. Flexible trust anchors, not trust lists or root authorities.
Runtime Verification
Validate credentials and evaluate trust paths before your systems act. Policy enforcement at the point of decision. Auditable, deterministic, fast.
Artifact Types
Media. Software. Workloads.
Unified integrity infrastructure across everything your organization creates and runs.
Media
Images, video, audio. C2PA credentials from capture to distribution. Provenance chains, editing history, licensing assertions.
Software
JARs, NPM packages, containers, binaries. SLSA provenance, in-toto attestations. Build metadata, supply chain verification.
Workloads
AI agents, data pipelines, services. Workload identity, capability credentials. Runtime authorization across trust boundaries.
Trust Graph
Ungameable. Unhackable. Uninfiltrateable.
Easily join, manage, and curate trust relationships. Bootstrap and run trust ecosystems backed by cryptography — ecosystems that can't be hacked, gamed, or infiltrated.
Join
Discover trust ecosystems aligned with your values. Subscribe to trust policies from organizations you believe in.
Manage
Curate your own trust graph. Add, remove, and weight trust relationships as your needs evolve.
Bootstrap
Create trust ecosystems for your community. Set policies, invite members, build networks that can't be corrupted from outside.
API-first architecture
Integrate integrity into your existing workflows. REST APIs and SDKs for every capability.
- Issue credentials programmatically
- Sign artifacts in CI/CD pipelines
- Verify provenance at runtime
- Query trust relationships
- Enforce policies before deployment
# Sign a media artifact with policy

No vendor lock-in
Built on specifications you can take anywhere.
