Abstract
This paper proposes a model for an Electronic
Health Record for Health Data Exchange based on a SaaS
(Software as a service) service model developed on top of
cloud computing technology. Service oriented architecture
(SOA) and SaaS enable establishment of service model by
leveraging the benefits of both. In the proposed model EHRs
are stored in the cloud, and can be accessed through a web
portal or background web services through SOA. The system
is using Health Level Seven International (HL7) standard
and is capable of storing information on: healthcare
processes, resources, users and authorization, also capable of
recording of all data on the patient history, diagnostic test
data, therapy, decisions request for further investigations,
and treatment. The system is set up to support the use of
technologies, decision support and management plans.
Owners of EHRs are responsible for generating access
policies based on the attributes of authorized healthcare
providers, encrypting EHRs and uploading encrypted EHRs,
digital signing of all request for getting data and digital
signing of response into the cloud. EHRs is organized into a
hierarchical data structure, which give possibilities to share
different parts of the EHR making our model more flexible.
