Medifi: An end-to-end encrypted decentralized file sharing network for the secure transfer and easy use of medical records

Medifi is a Web and Android decentralized application (DApp) to share Medical Documents securely via NFC. It can potentially store any medical records securely. The medical documents are uploaded by your doctor or other medical professional who is already trusted by the user. On a high level, this application can be used to share sensitive medical documents in a secure and accessible way. The target audience includes anyone who needs ready access to their personal medical records.

The Problem

In the United States, accessing one's own medical records can be a timely and frustrating process. It can take 30 days to gain access to medical records and often the request for access is denied improperly. Even if access is gained it can be unreasonable to search through and manage the thick stack of papers. This is a process known for its incredibly inefficient and cumbersome process - there is clearly much room for improvement. There have been attempts to digitize medical records and other similar sensitive data using traditional Web 1.0 and Web 2.0 technologies, but these have fallen short. For example, there have been cases of staff abusing their adminstrational access to patient records. Traditional databases continue to be the subject of hacks as we have recently seen with the Equifax hack and the ransomware attacks plaguing unsecure databases. With a database acting as a single point of failure it seems this problem cannot be resolved unless a nontraditional approach to data storage is explored.

The Solution & Medifi

Web 3.0 has brought with it a potential solution for the problem detailed above. Medifi's solution has leveraged these emerging technologies to create an end-to-end decentralized file sharing network. This means there is no longer a single point of failure for hackers to exploit. The data itself is secured using SHA256 in a Merkel DAG data structure and users can access the data using the hashes of the SHA256 encryption traced with the help of the Ethereum Blockchain and smart contracts. This means that data can be added and viewed with ease and be stored completely securely. Which means that you will no longer have to wait thirty days to access your own medical records and sharing your medical records with trusted sources will be easier and more secure than ever before.

What is DApp?

Take it from the top answer on stackoverflow:

DApp is an abbreviated form for decentralized application.

A DApp has its backend code running on a decentralized peer-to-peer network. Contrast this with an app where the backend code is running on centralized servers.

A DApp can have frontend code and user interfaces written in any language (just like an app) that can make calls to its backend. Furthermore, its frontend can be hosted on decentralized storage such as Swarm or IPFS.

If an app=frontend+server, since Ethereum contracts are code that runs on the global Ethereum decentralized peer-to-peer network, then:

DApp = frontend + contracts

Inspiration :

Analyzing the cybersecurity events in the medical industry, we realized there is a huge data security issue as well as the need to simply access medical records easily. Especially Arkansas Oral Facial Surgery Center was hit by a cyber attack that shut the organization out of files, medical images and details of patients visits. So we came up with the idea of storing the sensitive data on a decentralized platform, thus making protecting it from single point failure issue.

Challenges we ran into

Understanding the necessary requirements to build an entirely secured application in a decentralized manner.

What we learned? We learned about blockchain technology, smart contracts, and decentralized systems.

What's next for Medifi We wish to continue to research on end-to-end encryption and smart contracts in order to built a more robust and scalable system to meet the demands of an enormous industry.
