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 confirm integrity and origin using standard phones — without exposing secret keys.
root@trustec:~/products/logihash/demo $ verify --tcode
# Live in-app preview
> Real T-Code — full verification flow_
This uses the same deterministic demo payload as the Try intro video: real signatures, real decryption, and the same metadata you see in the API examples (John Doe / Contract). After the success screen, we switch to an ordinary QR on the same interface so you can compare outcomes.
> 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.

# LogiHash is a verification infrastructure layer. It is not presented as a universal replacement for qualified electronic signatures, qualified trust services, eIDAS services, document-management systems, or secure transmission platforms.
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.
