The Digital Integrity Platform

The internet has an authenticity problem.

If people can't tell what's real, how can agents? We provide the infrastructure to make integrity verifiable — for structured data, context graphs, and the systems that reason over them.

Platform

Four capabilities. One platform.

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.

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"
