    Invisible Watermarking

    Embed Proof Without Degrading the Asset

    ProofChain uses our invisible watermarking algorithm from Tectus to embed a unique identifier into your media before distribution. Publish unique watermarks for each channel carrying a distinct payload. So when infringing content is discovered, you can decode the watermark and answer: “Where did this come from? Which channel is leaking?”

    No original file required: the watermark survives compression, cropping, and re-encoding, so ProofChain can identify the distribution source from any copy found in the wild.

    Protection That Survives the Real World

    Metadata is fragile. Our invisible watermarking is AI-driven and survives compression, cropping, and format changes to keep your ownership link intact.

    How ProofChain Works

    1

    Watermark & Publish

    AI analyses content and embeds a unique, invisible watermark at the moment of creation.

    2

    Blockchain Anchoring

    Ownership metadata is hashed and time-stamped on the blockchain, creating an immutable public record.

    3

    Instant Verification

    Query the API to validate any asset in seconds, confirming authenticity against the blockchain entry.

    Key Features of ProofChain

    Resilience

    Watermarks are indelible, surviving heavy editing and compression.

    Verification

    Provenance is verified via a decentralised public ledger, not a vendor silo.

    Watermarking Mode

    Uses invisible watermarking so marks cannot be seen or stripped visually.

    Visibility

    The embedded watermark is invisible to viewers while remaining machine-readable.

    Integration

    Fully API-first for automated workflows with no manual portal required.

    Built for Automated Workflows

    // POST /api/v1/verify { "asset_id": "img_89231", "hash": "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855" } // Response: 200 OK // Verified: True // Blockchain_Block: #8921004

    Proof-of-Provenance

    Register on a Public, Immutable Ledger

    The blockchain proof-of-provenance layer records each asset's unique watermark and timestamp on a public, immutable ledger. Anyone can verify ownership and provenance independently, without relying on a centralised registry.

    Automated Registration

    Seamless, Rapid Embedding and Blockchain Record Creation

    The automated registration workflow ties invisible watermark embedding and blockchain record creation into a single, seamless process. Register assets at scale with minimal manual steps and get instant verification via API.

    Decentralised Public Record

    A Defensible, Accessible Proof of Ownership

    The decentralised public record system makes proof of ownership highly defensible in disputes and accessible to anyone with the asset. No single vendor controls the ledger; verification is independent and auditable.

    FAQ

    Questions, Answered.

    01What is ProofChain?
    ProofChain is a blockchain-anchored watermarking and verification service that embeds invisible watermarks into images, video, and audio, then records ownership metadata on a public blockchain ledger. This creates an immutable, decentralised proof of provenance that anyone can verify independently.
    02How does blockchain anchoring work?
    When an asset is registered, ProofChain hashes its unique watermark and timestamps it on a public blockchain. This creates a permanent, tamper-proof record that proves when the asset was registered and by whom. Because the ledger is decentralised, no single party can alter or delete the record.
    03What types of watermarking does ProofChain offer?
    ProofChain uses invisible watermarking to embed ownership proofs into images, video, and audio. The watermark can be configured to confirm that an asset belongs to you, or to carry a unique payload (such as a user ID or timestamp) that enables forensic leak tracing when a copy appears in the wild.
    04Which file formats does ProofChain support?
    ProofChain supports images, video, and audio formats. Invisible watermarks can be applied across these media types, and blockchain anchoring works independently of the file format, so your ownership record is always verifiable.
    05How does verification work?
    Verification is API-based and instant. You submit an asset or its hash to the ProofChain API, which checks the embedded watermark and cross-references the blockchain record. The response confirms authenticity, ownership, and registration timestamp in seconds, with no manual steps required.
    06How does ProofChain differ from traditional watermarking?
    Traditional approaches rely on visible marks or fragile metadata (EXIF/IPTC) that are easily stripped on upload or re-encoding. ProofChain's watermarks are invisible and survive compression, cropping, and format changes. Combined with an immutable blockchain record, this provides forensic-grade evidence that does not depend on a single vendor's registry.
    07How do I get started with ProofChain?
    Request a demo and our team will walk you through the integration. We assess your asset types, protection goals (ownership proof or leak tracing), and workflow requirements. You then receive API credentials and can begin watermarking and anchoring assets immediately.
