• CONTEXTsoftware-design to organize telemedicine services

• MOTIVATIONSnecessity to integrate health services in a wide and delocalized environment

• SCOPEto provide a flexible architecture for teleconsulting and telereporting

MiRo -MiRo - FinalitiesFinalitiesMiRo -MiRo - FinalitiesFinalities

• provides a flexible software framework for teleconsulting and services development

• integrates with the existing health information system to facilitate and rationalize information interchange

• improves and facilitates TCP/IP-based teleconsulting services in Intra/Internet environment

• provides a report and “second opinion” service

Abstract Data-StructureAbstract Data-StructureAbstract Data-StructureAbstract Data-Structure

• Exam-data: generic digital data produced by an examination

• Report: text-file and digital signature

• Event: database record containing– the date-time of the insertion in the database– the examination type– the laboratory who produced it

9

DATA-STRUCTURE• Data: digital data produced

by an examination

• Event: database record that links to the exam

• Report: text-file containing report

SYSTEM-ENTITIES• Repository: archives event

• Laboratory: generates event

• Phisician: reports examination

• Allows laboratories to generate and manage events

• Allows phisicians to control and report examination

• Stores reports allowing teleconsultation

Acts as a sophisticated DBMS for event-records

• Consults published examination

• Consults reports written by other phisicians

• Compiles and signs report

• Send this report to a timestamp service and then to the repository

1. Laboratory executes an examination that produces digital data

2. Laboratory pubblicates exam through the creation of an event

3. Phisician compiles and signs a report and sends it to the timestamp service

4. Timestamp service appends a certificated datetime to the report and forwards this back to the phisician

5. Phisician sends this composite-data to the Repository

6. The Laboratory decides when to terminate the refertation process

MiRo -MiRo - TechnologiesTechnologiesMiRo -MiRo - TechnologiesTechnologies

• Service-Oriented Architecture based on common standards widely applied in different health contexts

• implemented through Web Services (SOAP, XML, …), which are becoming a standard to distribute services inside an heterogeneous environment such as Internet

• Client can enter in any moment to consult and to insert event or report data using a common Web Browser

• transactions are encrypted through standard SSL X509.v3, using standard Digital Certificates

19

MiRo – Development EnvironmentMiRo – Development EnvironmentMiRo – Development EnvironmentMiRo – Development Environment

• Java 2 Platform Standard Edition• development tools:

– Eclipse 3.1 – as development environment– Apache Axis and Java Servlet – to realize web services– Apache Struts and Java Sever Pages – to design web

interfaces

• Java web services technology– JDBC interface (in our case MySQL).

• Clients adopt just Web Browsers

20

MiRo -MiRo - Security LayerSecurity LayerMiRo -MiRo - Security LayerSecurity Layer

• Secure Socket Layer(SSL)– Confidentiality achieved through cryptography,

guarantees that data can exclusively be read from the authorized user.

• Digital Sign– Integrity and no-repudiation, achieved through the

digital sign, guarantees that information are not modified during the transmission and that those who use the system assume the responsibilities of what they are doing.

– Authentication achieved through digital certificate, Username and Password, guarantees that the user is exactly the person he declares to be.

Conclusions and future worksConclusions and future worksConclusions and future worksConclusions and future works

• MiRo is a software architecture for TCP/IP-based telereporting activities and “second opinion” services

• thanks to its flexibility, can be exploited in many different operational realities and is able to incorporate different Intra/Internet-based services.

• In future perspective, we foresee the possibility to implement and to provide new services and to reach citizens.
