HIPAA certified
Blockchain Enabled Chat Platform
Challenge
The client reached out to us with a need of implementing a chat platform that can be accessed by the hospital doctors and admin team to communicate critical patient information and other OPD details. The platform will be used to send documents that need to be tamper proof and was expected to provide evidence if it underwent any changes.
The client had an idea, but they needed a technical partner:

Methodology
Our team took a systematic approach
with the following key steps
Chat design with a focus on preserving privacy
The design focuses on ensuring every data and conversation is encrypted in transit and also in rest. The sockets are designed to decrypt a chat message only in the client using an asymmetric key with the public key held by the hospital and the private key stored in the user’s device.
Architecture design to ensure scalability
The architecture uses a combination of micro-frontend, micro-services, sockets deployed and managed using docker and orchestrated using a cloud based API gateway.
Immutability of documents and records
To ensure immutability of records and to ensure non-tamerability; an IPFS server was deployed as a private gateway (without any public replication). IPFS ensures every content is written as a hash and at any point of tampering the records, the hash for the file is re-written but it does not change the source. This helps the hospital preserve its files, ensure no duplicate files are created and prevents tampering of records.
