The files are typically huge, and they need to be kept strictly confidential. Blockchains are publicly visible, and they accumulate data without limit. All participants’ records are stored on the blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors., and they’re never deleted. A blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors. of medical images could grow to gigantic size in a short time, making it difficult to store and update.

MedAI Network is attacking this issue, claiming to find a way to put medical images on a blockchain. Its whitepaper discusses what is involved but still leaves questions open.

MedNetwork

The software is called MedNetwork. It handles the privacy issue by encrypting the image data. The patient holds the “private keys or password” for decryption and can grant access rightsToken rights refers to the broad spectrum of how a token is used to facilitate a transfer of value within cryptoeconomics. Application tokens are generally specific to an application where as protocol tokens (i.e. Bitcoin, Ethereum etc.) operate on the broader network the application is running on. Depending on the business model, token rights can take on any number of shapes. Payment tokens for examples, may be the only way to make payments on the network where as access tokens provide the ability simply to access the network. Other models of token rights include governance, where holders influence development road maps and contribution rights, where tokens are needed to play a role on the platform. Tokens play a key role in developing the type of consensus protocol best suited for the business model.... More to others on a selective basis. MedAI argues that this is more secure than existing systems, where each healthcare provider has its own repository. The lack of a consistent method of granting access can lead to security issues when trying to share information.

According to the whitepaper, telemedicine has led to growing use of imaging, and imaging is one of the biggest factors in increasing medical costs. The company expects that its approach will provide a better infrastructure for images and decrease the storage and access costs.

Artificial intelligence is a major component of the design. AI diagnostics, built into the blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors. as smart contract code, will assist physicians in diagnosing conditions from images.

Current status and plans

An alpha release of the software is currently available, and people can sign up to try it out. A beta release, version 0.1, is promised for March 2018. The alpha version includes a prototype for the storage engine and AI code based on algorithms licensed from SemanticMD.

The storage engine focuses on security that will satisfy HIPAA requirements. Imaging conforms to DICOM standards.

The first public phase is scheduled for April 1 to April 14, 2018, and the second for May 1 to May 14. By running an ICO, the company hopes to better engage the blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors. community. MedAI also has backing from Mercatus Capital.

The ultimate goal is “to become the storage layer of the decentralized Internet.”

Questions and concerns

MedNetwork is taking on two challenges at once: the storage of images on the blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors. and the incorporation of AI software to interpret them. Either one is a major task by itself.

To succeed in its aim, MedNetwork needs to address two difficult issues. The first is the scaling problem. Medical images are typically megabytes in size, even with compression. If it’s going to be the destination for images for millions of patients, the blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors. could grow into the terabytes or petabytes. This presents scaling issues, as each copy of the blockchainA Blockchain computing system treats the Blockchain as a secure computation platform that can be shared among multiple vendors. has to be kept in sync with the others. MedAI needs to explain how it will manage scaling, and what economic incentives storage providers will have for handling so much data.

Another issue is granularity of access. The patient is supposed to be able to grant specified parties access to specific records. According to the whitepaper, records are secured by the patient’s private keyQuantum key distribution (QKD) uses quantum mechanics to secure a communication channel. It enables two different parties to develop a shared random secret key known only to them, which can then be used to encrypt and decrypt messages. What makes quantum key distribution unique is its ability to enable the two communicating users to detect unwanted attempts at trying to gain knowledge of the key. This ability is supported by a fundamental aspect of quantum mechanics: the process of measuring a quantum system in general disturbs the system. If an attacker is trying to eavesdrop on the key, the attacker must in some way measure it, thus introducing detectable anomalies.... More, and “without the key, the data is secure and inaccessible.” That seems to imply all-or-nothing permission for all a patient’s records.

A whitepaper is not a technical document, so it’s quite possible answers to these questions exist. Companies developing new technologies are naturally reluctant to reveal too many technical details. Still, MedAI will need to convince investors that it has answers. If it does, it has a solution to one of the most difficult issues in healthcare blockchains and could become a very important player.
