A Trustec Valley product

# Trust that travels with the asset
> Verify authenticity in seconds: Not with trust in a screenshot.
LogiHash binds encrypted metadata to a scannable T-Code so anyone can, without exposing secret keys, confirm integrity and origin using standard phones.
root@trustec:~/products/logihash/demo $ verify --tcode
# Live in-app preview
> Real T-Code: full verification flow_
Live demo with real signature verification and decryption, using the same metadata as our API examples (John Doe / Contract).
> status: VERIFIED
root@trustec:~/logihash/problem $ cat README.md
> The problem_
Documents, credentials, invoices, labels, and parcels can be copied, modified, or falsely presented as genuine. Traditional QR codes often redirect to a URL but do not necessarily provide cryptographic evidence that the scanned object matches a genuine issuance.
root@trustec:~/logihash/approach $ cat README.md
> Our approach_
Each protected asset receives a T-Code containing a signed structure linked to encrypted metadata and issuer information. Verification checks whether the T-Code has a valid structure and corresponds to a genuine issuance. The underlying technology is covered by a patent application filed on 21 May 2024.
root@trustec:~/logihash/how $ cat README.md
> How it works_
01
Issue
An authorized organization generates a T-Code through the console, API, or an integrated workflow.
02
Attach
The T-Code is added to a digital document or physical object.
03
Verify
A recipient scans it with a supported mobile or web workflow.
04
Understand
The recipient receives clear authenticity, integrity, issuer, and status information based on the available verification data.

Test LogiHash in a real workflow
Trustec Valley works with selected organizations to evaluate LogiHash in practical use cases and integration environments. Pilot scope, duration, data handling, responsibilities, and success criteria are agreed individually. LogiHash is in an early market and pilot stage.
