IdenTrust says HSBC is joining its digital trust network to enable corporate customers to digitally sign payment files to provide secure, non-repudiable and legally binding corporate-to-bank and bank-to-corporate communications.

The vendor says that its system streamlines the authentication process as only one identity per user is needed to interact with all of a customer's banks.

Identrust says HSBC is undertaking a series of customer implementations of the technology to demonstrate the scalability and interoperability of the system.

Joe Norburn, managing director, Emea, IdenTrust, says: "Our ability to provide an authentication solution that is interoperable, non-repudiable and valid in more than 100 countries is essential to HSBC, whose corporate clients conduct business around the globe."

In addition, IdenTrust says it is working with HSBC to identify other business areas, such as bank account management processes and trade finance services, that may benefit from the technology.

Last September French bank BNP Paribas said it was using the Identrust technology to enable its corporate banking customers to use personal digital signatures for SwiftNet FileAct payment files.
