?

Ping
Identity and MedCommons Use SAML 2.0 for Electronic Health
Record
Access
Staff, Ping Identity Announcement
Ping Identity
and MedCommons have announced a partnership to develop
secure,
standards-based, single sign-on solutions for
multi-location
electronic health record access and storage. Both
Ping Identity and
MedCommons are committed to SAML 2.0 as the
standard of choice for
secure authentication precisely because it
provides for the convergence
of non-interoperable standards that
support Web SSO. After significant
testing of alternative providers,
MedCommons determined that
PingFederate Version 3 was the easiest
SAML 2.0 product to acquire,
install, configure, integrate, and
deploy. MedCommons quickly integrated
PingFederate v3 into their
medical data network and secure storage
solution, enabling Web SSO
using SAML 2.0. "Ping Identity's products and
services help
organizations easily and cost effectively bridge security
domains
across partner, supplier and customer organizations by
providing
secure Web SSO. MedCommons has developed the first
standards-based
system capable of communicating with and
transferring image and
non-image data among Personal Health Records,
Electronic Health Records
(EHR) and national healthcare IT
systems."
