INTRODUCTION

This project is a proof of concept for the health care industry demonstrating the ability for hospitals, insurance companies and pateients to act in a decentralized manner where hospitals can issue documents for patients and the insurance companies can trust that the documents were indeed signed by the hospital for the specific patient. This solution use digital signatures.

PROJECT STRUCTURE

• HealthCareSSIApi - Web API around core business logic
• HealthSSI.Core - Core business logic using digital signatures
• HealthSSI.Data - Data layer for Database (Currently MSSQL)
• HealthCareSSI.Tests.Common - Common test library for helper functions for things like getting a key pair
• HealthSSI.Core.Tests - Unit tests for signature and document proof checking
• HealthSSIApi.IntegrationTests - Integration tests testing end to end case of hospital document inssuance verification

REQUIREMENTS

HealthSSI requires the following:

• .Net core (3.0.0)
• Newtonsoft.Json (12.0.3)
• RestSharp (106.10.1)
• Swashbucle.AspNetCore (Swagger) (5.0.0)

INSTALLATION

To install locally, do the following:

1. Clone the repo
2. Perform a Nuget restore of all packages
3. setup or use appsettings.Local.json for local dev
4. Set ASPNETCORE_ENVIRONMENT var with $env:ASPNETCORE_ENVIRONMENT='Local'
5. Create db local with command Update-Database

CONFIGURATION

HealthSSI is a .Net core application which uses appsettings.json files for Configuration. appsettings.json serves as the base config file. It supports additional config files for environment specific variables. Locally or on the server, ASPNETCORE_ENVIRONMENT needs to be set which will instruct .Net core to read in the appropriate settings file.

INFRASTRUCTURE

• HealthSSI is currently deployed in AWS using EBS and MS SQL on RDS. http://healthssi-env.uxpb73mr6m.us-east-1.elasticbeanstalk.com/swagger/index.html
• DB: healthssi-db.cvzjpppmueiv.us-east-1.rds.amazonaws.com
• The database schema is currently being maintained via code first migrations.
• Deployments currently being done via Visual Studio AWS Toolkit.
• https://aws.amazon.com/visualstudio/

TESTS

There are three test projects:

• HealthSSI.Core.Tests (unit tests)
• HealthCareSSIApi.IntegrationTests (integration tests)
• HealthCareSSI.Tests.Common (shared test lib)

NEXT STEPS

• Use HSM for keys - AWS supports HSM which is FIPS 140-2 level 3
• https://aws.amazon.com/cloudhsm/
• https://en.wikipedia.org/wiki/FIPS_140-2
• Add authentication to API
• Containerize project
• Setup CI/CD
• Add integration with Sovrin network
• Separate out into separate services if need be?
• Hash contents of Document and place on a blockchain
