4Trust Chain of Custody

Trust + Provenance + Finality

‘Your Partner in Document Provenance’

The TALL Group of Companies provides an innovative Chain of Custody and transaction verification platform that delivers absolute confidence and certainty to the user, provides real-time authentication and eliminates the risk of fraud.


  • Enterprises universally agree that document management costs are out of control
  • Document fraud has huge reputational, financial and regulatory costs
  • Authentications linking the document, its holder and the relevant transaction cannot be undertaken in real time
  • Operational performance and regulatory compliance are hindered by the lack of real time links between documents and their supporting archives



The 4Trust Chain of Custody platform provides a unique and proprietary capability to link its fraud-proof documents in real time (Android, IOS, Windows-based applications) to the document’s encrypted archive.
