Ensure your data's integrity with unquestionable certainty

Codelmarking applies a cryptographic signature — a unique, time-stamped fingerprint — to any digital asset, creating a permanent record that cannot be altered, forged, or denied.

How Codelmarking works

🔐
Immutable Records

Every codelmark is cryptographically bound to its data. Any alteration — however minor — is instantly detectable.

Precise Timestamps

Marks are anchored to a trusted time authority, providing court-admissible proof of existence at a specific moment.

🌐
Distributed Verification

Verification requires no central authority — any party can independently confirm the integrity of a marked asset.

🔑
Role-Based Access

Granular permissions control who can read, mark, or audit each asset — with a full tamper-proof audit trail.
