WEBFORT ENSURES CONFIDENTIALITY TO IRETRIEVE USERS.

Arcot Systems, Palo Alto, Calif., a provider of authentication solutions for the Internet, and infoMedX.com, the first Internet-based healthcare application services provider (ASP), has announced that Arcot's WebFort software provides strong authentication for users of iRetrieve, infoMedX.com's flagship Internet-based document storage and retrieval system. With Arcot's "cryptographic camouflage" technology, doctors and clinics can use iRetrieve's powerful, convenient electronic patient records management solution with complete assurance that patient confidentiality and document security remain uncompromised.

"The security and confidentiality of patient records is top priority for our customers. Arcot's WebFort is the authentication component that makes iRetrieve's groundbreaking four-tier security model possible," said Cliff Cancelosi, chief operating officer for infoMedX.com. "It allows us to provide our customers with security that exceeds regulatory requirements, and does so without the use of smart cards or other added hardware."

iRetrieve secures patient chart information through infoMedX.com's groundbreaking security model. The four-tier security model utilizes 128-bit encryption, WebFort's two-factor authentication, role-based user access, and a feature that prevents the web browser from writing files to the local machine. These four layers all work in unison to assure that confidential information remains confidential as it is passed up and down Internet channels.

"Healthcare is undergoing a technological revolution centered around the Internet, and infoMedX.com is the first to offer doctors and healthcare administrators a complete clinical ASP solution," said Steve Levine, Arcot vice president of marketing. "Arcot technology provides the strong authentication critical to the security and success of infoMedX.com's iRetrieve."

With a focus on healthcare, financial services and eBusiness applications, Arcot's WebFort product suite enables the convenient, cost-effective volume deployment of strong user authentication on the Internet. Arcot's patented cryptographic camouflage technology securely safeguards the private key by 'camouflaging' it among tens of thousands of well-formed false private keys. Arcot's WebFort product suite is the only software solution providing the security of hardware authentication solutions.
