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.

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

Your community. Your trust. 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
curl -X POST https://api.noosphere.tech/sign \
  -H "Authorization: Bearer $TOKEN" \
  -F "file=@image.png" \
  -F "policy=media-production"

# Verify credentials and trust path
curl https://api.noosphere.tech/verify \
  -F "file=@image.png" \
  -F "trust_policy=our-partners"
