Trusted digital interactions start with trust
Qualified Trust Service Provider (QTSP)
Whether someone identifies themselves, gives consent, signs an agreement or approves a transaction, organizations need confidence that every digital interaction can be trusted.
AET helps build that trust foundation.
For organizations that depend on digital interactions between citizens, customers, professionals and employees.
The challenge
Digital interactions are becoming more important
Organizations increasingly depend on digital interactions between citizens, customers, professionals and employees. However, trust is often fragmented.
Identity
Can we trust the identity behind the interaction?
Approval
Can we prove who approved a transaction?
Signature
Can we demonstrate legal certainty when it matters?
The solution
