Finnish banks' Tupas certification service allows businesses and organisations providing Internet services to authenticate their customers with Tupas certificates issued by the Tupas service. In the Tupas service a bank authenticates a customer by a strong authentication method. The Tupas certificates issued by the service can also be used for signing documents electronically if so agreed by the customer and the service provider.

The Tupas service is jointly defined by Finnish banks. Each bank authenticates its customers with the same bank-specific identifiers that the customer uses in the bank’s own services.

This module provides Drupal integration to Tupas certification service and it can be used for using digital signatures to grant additional permissions for users.

The development of this module has been initially done by dotsi and sponsored by Exove Ltd (www.exove.com).
