First public digital certificate code signing service for

Smartphone application developers; provides wireless application

identity validation, prevents application theft and virus attack

GeoTrust, Inc., a leader in identity and security solutions for e-business and the world's second largest certificate authority and Baltimore Technologies (London: BLM), a global leader in e-security, partner to announce Smartphone Credentials(TM), the first public security service to ensure the authenticity of software applications for the Microsoft Windows Powered Smartphone.

Leveraging the Baltimore Technologies cryptographic root embedded in the Microsoft Windows Powered Smartphone and Baltimore UniCERT(TM) PKI, GeoTrust will provide a secure code signing service to Independent Software Vendors (ISVs) that develop applications for the Microsoft Windows Powered Smartphone. This security service will validate the identity of the vendor and the integrity of the applications to ensure that the code released from ISVs is the code that is actually delivered to the Smartphone. As a result, mobile phones will, for the first time, have the security to thwart rogue application theft and malicious virus attacks. The new service, Smartphone Credentials, is available now and can be purchased at www.geotrust.com/codesigning/smartphone/index.htm.

Microsoft Windows Powered Smartphone provides a rich data platform for mobile developers and operators to build compelling mobile data applications and services. Mobile phones built on the Smartphone platform combine fully integrated voice and data capabilities with a rich set of applications including personal information management (PIM), gaming and multimedia features in a small, lightweight mobile phone form factor.

"Smartphone Credentials service signals GeoTrust's commitment to the wireless market where we expect significant future growth," said Neal Creighton, CEO of GeoTrust, Inc. "We are pleased that both Microsoft and Baltimore see tremendous value in adding GeoTrust to this important initiative."
