Of the various concerns of the healthcare industry, Medical data security is one of the most important ones. There is a definite need to take care of these medical data, as these days are more prone to data hacking. For instance, there are cases reported in USA, Australia, Norway and other countries where medical data is leaking. Only in US, data leakage cases are accounted for 392 cases that counts for more than half of the global total. In this data breach cases, Canada is standing second with 21 cases, followed by UK 20 cases, followed by Quarter with 17 cases. Other countries are less prone to such incidences, and the number of such cases there did not exceed 7.
Not just the leaks, but also the transfer and communication of patient’s medical data is becoming difficult between healthcare systems and vendors. This is showing impact on the quality of treatment and patient care. Most of the patient’s health data is via consumer technologies like wearables, mobile health apps, fitness trackers and all such. If these are not incorporated effectively, that may lead to data breach problems. Particularly, such kind of concerns arise when multiple vendors are having the same patients data which are not validated, thus results in inconsistency, errors and incompleteness.
Medical Data security issues resolutions:
BlockChain technology offers various advanced solutions for the medical data security and management issues. At industry or even at global level, the healthcare data architecture need to be reshaped, this opens a new door for innovation.
A Review at Harvard business, presented by MIT researchers Andrew Lippman and Ariel Ekblaw and John D.Halamka, MD, CIO at Beth Israel Deaconess Medical Center, BlockChain will generalized the past medical records, thereby there is no need for custom programming for working with individual EHR vendors. This results in scaling up the scales very quickly.
Yet, as per Robert Plant, Professor at University of Minami, some questions are waiting to be answered like granting private key access to a trusted family member or friend in case of any emergency.
Various countries like Estonia are trying the BlockChain technology at the government level, in 2017, all the health records of about half of their citizens are secured using blockchain as per Medical Futurist. Whereas, America has lot to do before its citizen data is secured using blockchain, it is on roadmap. Using DokChain, PokitDok is doing the part by distributing the network of transaction processors which operate on clinical and financial data in the healthcare industry.
The main motto is to materialize healthcare economy where data and services are exchangeable and quantifiable, at the same time privacy and security of the sensitive information are kept strongly safe and the various transaction histories can be audited longitudinally.
Universal Health Coins
Universal Health Coins can be used for reducing the medical data breach issues. Using BlockChain technology, third party entities can be eliminated, thus managing the payments for services between providers and patients for reducing the cost of unnecessary administration and inflation due to lack of free healthcare market. This will also serve for medical data security. UHC, is not just health insurance, rather it declares itself as an anonymous, token-based shared health cost network’. Members of UHC network pay monthly fee voluntarily and in exchange of that they earn digital universal health coin, which is validated via blockchain technology. These coins can be used for direct payment for services.
Wearable and IoT Data Collection
US Food and Drug Administration in collaboration with IBM Watson Health explore the health data transfers from the wearable and other IoT devices via Blockchain. This will help in safe transfer of health data making it easily available to the researchers, healthcare providers and patients. As these transfer are based on blockchain, it ensures the safety of the data security and its associated risks.
Though the blockchain ledger is public, it is very much secure as the data is replicated across the blocks in the network. It is very much secured than the traditional information storage system as the data is in single location, i.e., Centralized. The access control in blockchain is via shared public chain and private chain. For example, Only the concern person will have the access to the private chain piece. If hacker was to breach the data, it distributes every participants in the network.
The major issue of healthcare industry, i.e., medical data security is influenced positively by blockchain at global level. For this to happen, one need to have a strong technical support. The demand for blockchain healthcare technology is on raise as the threats of data breach is high.
