Data security in the modern healthcare sector needs improvements.
HIPAA-covered entities have reported that in March 2019, the amount of healthcare data breaches increased by 14% compared to the average rate of the last sixty months.
As a result, the volume of exposed patient medical records has continued to grow. In March 2019, the medical information of 912,992 patients has been either stolen or exposed.
The biggest incident took place at Navicent Health, a healthcare provider. Phishing led to 278,016 records being illegally accessed and copied.
ZOLL Services LLC reported on another case where the information of 277,319 patients on the network server was hacked and exposed.
The HHS’ Office for Civil Rights has identified the main causes of these breaches. They are ransomware and malware attacks.
This situation in the medical industry can’t last forever and effective solutions have to be implemented.
Healthcare blockchain technology is one of the solutions that can drive change. So, in our post, we are going to describe how blockchain software can help secure patient data storage and:
- Eliminate the risk of medication forgery
- Increase the performance of clinical testing
- And make medication transportation tracking more effective
Blockchain Healthcare Technology for Secure Patient Data Storage and Transfer
As discussed above, patient-related data storage is one of the most important aspects of healthcare which requires thorough protection.
Medics put privacy to significant risks when transferring medical cards information via social networks or other insecure channels.
Obviously, stealing of such data can cause its illegal publication without the patient’s permission and subsequent blackmailing.
In 2017, the Digital Treasury Corporation, in cooperation with the Taipei Medical University, introduced phrOS, a blockchain-based operating system for personal healthcare records.
phrOS places patient information on blockchain to achieve transparency between various medical organizations. It also increases information security via the Decentralized Ledger Technology (DLT).
Both doctors and patients have access to this data through a mobile application. Patients can input data about their current health condition, and doctors can monitor it in real time.
Another blockchain healthcare solution is MyClinic.com. This service was developed by Medicalchain, a UK startup, together with the Groves Medical Group, a private clinic chain.
Like phrOS, this blockchain software aims to provide a transparent and secure way to transfer electronic healthcare records (EHRs) between patients and doctors.
With this solution, patients can receive a consultation with a real doctor remotely. The fee is reduced because there is no need to pay for transportation and rent. It is paid directly to the specialist without any third parties.
Innovecs can integrate blockchain into your existing healthcare software or develop a solution from the ground up. For one institution, our engineers helped create a blockchain healthcare product for verifying and storing medical data changes.
Blockchain Healthcare Technology for Eliminating the Risk of Medication Forgery
Medications are faked as often as any other type of production. However, as opposed to other products, the forged remedy can not only show no effect whatsoever but also significantly harm the patient’s health.
It is estimated that 1 million people die because of counterfeit medications. The World Health Organization has reported that approximately 10% of all medicine in the world is forged. It relates mostly to locations such as North America, Asia, and Europe.
The Organization for Economic Cooperation and Development (OECD) has estimated that the counterfeit medical sector costs more than $200 billion yearly. Compare this figure with the illegal drug trade, which is worth near $250 billion.
Blockchain healthcare technology can help reduce risks caused by fake remedy, and consequently, save lots of people’s lives.
Each transaction written into a certain block is recorded and cannot be changed in any way. In such a manner, pharmacists are able to retrace each stage of a product’s delivery – from the manufacturer’s storage to end buyer.
Blockchains with both public and private access can be used in that case. The private type of access is more preferable as it simply does not let in any cheats forging the medication.
Why is blockchain more beneficial for the solution of that problem as opposed to conventional means?
The blockchain technology, in turn, makes it practically impossible to change information stored in its sections. It can, additionally, help the pharmacists identify on which stage the violation was made in the case of detecting a low-quality product.
Recently, SAP, a German technology company, has introduced a blockchain healthcare software for eliminating the counterfeit drugs.
According to SAP’s new blockchain-based product, pharmaceutical producers have to indicate the data about the medicine on the ledger. They have to direct XML messages through the SAP environment which will then make these messages emerge on blockchain.
The data on blockchain will be kept in SAP’s cloud and will be accessible for all supply chain participants. Thus, no third parties could access, copy, or modify it.
This software best suits medicine manufactures. Blockchain-based AsliMedicine provides them with a unique coding model for each drug at the item level. Any data can be input: quantity, location, manufacturer name, asset ID, etc. This helps trace medicine for detecting counterfeit units.
Blockchain Healthcare Technology for Securing Clinical Trials
Clinical testing is conducted in order to identify the effectiveness of certain medication as well as its side effects. The tests usually can take up to a few years and require enormous investments.
A typical clinical trial consists of three phases. The first one entails testing medications on a small group of people; the second one — on a larger group; and on the last phase, the medications are distributed across the biggest group. The final step is the new drug application (NDA) approval. Only a small percentage of drugs pass all these steps.
Considering such a low percentage and the amount of money involved in the entire process, it is no wonder that some dishonest manufacturers can forge data. This is made to decrease the required period of time and a dedicated budget. In some cases, such affairs can result in incorrect medical notes as to the patient’s condition after the application of a certain remedy.
Thus, potential buyers do not suspect to what catastrophic side effects the application of that remedy can lead. They can cause deterioration in patients’ condition and even immediate hospitalization and fatal outcome.
The blockchain technology in healthcare can reinforce the genuineness of any document that confirms the result of tested medication’s application.
In order to fill the healthcare chain with new data, a user must await the confirmation of data put down in previous sections (i.e. computer networks that store previously written down data concerning certain medication).
As a result, the consumers’ level of trust towards the companies with blockchain technology in healthcare increases and they get an ultimate advantage over competitors.
Recently, IBM Canada and Boehringer Ingelheim have announced a partnership to test how blockchain healthcare software can facilitate clinical trials.
Their goal is to test the decentralized framework for information integrity, transparency, provenance, and patient empowerment. They also plan to implement automation into the process and, consequently, see whether the quality of the trials improves. This is the first time ever blockchain in healthcare is used in Canada.
BloqCube is a ready-made blockchain software that aims to speed up the clinical research and provide complete data integrity. The system allows integrating common clinical trial management systems (CTMS) with payment and accounting platforms on the basis of blockchain to receive a full-scale solution for medical institutions and clinical trial investors.
Blockchain Healthcare Technology for Simplifying Medication Transportation Tracking
By 2023, all medical organizations involved in the supply chain in the United States must meet the requirements stated in the Drug Supply Chain Security Act.
This act states that every medication unit in the supply chain must have its unique serial code, which will be indicated in the electronic database. By using this code, manufacturers will be able to accurately track the position of the drug in the healthcare chain.
In 2013, the government tried to enforce such an act. However, the attempt was unsuccessful while companies did not have a secure platform for keeping all serial numbers and tracking medicine.
In 2019, this problem should not occur with blockchain helping to handle the issue and remain law-compliant.
For example, in June 2019, Walmart started to harness the power of blockchain for pharmaceutical tracking to meet the regulations of the Drug Supply Chain Security Act. For this, the retail giant has partnered with organizations such as IBM, KPMG, and Merck.
“Blockchain is really good at creating audit trails (records of changes) to any file in a way that is easy to verify but secure. This can really help users keep track of their data. The cryptographic keys/signatures that access the chain are a good way to protect permissions, but they should not be considered silver bullets. All you need is the key to access the data.” has commented Jackson Adams, co-founder and COO at CareX Blockchain Platform.
According to the act, all drug packages have to be tracked separately. While conventional methods can’t provide tracking for a single item, blockchain healthcare solution comes to the rescue.
Blockchain aims not to replace existing systems, but to augment them to be more effective in terms of their tracking capabilities.
So, how does it work? Every new item (drug package) that is placed on blockchain gets automatically timestamped. This provides the opportunity to track this item and guarantees that the data inside the block can’t be modified which proves the drug authenticity.
There are some ready-made blockchain software solutions like MediLedger. This multi-functional software:
- Keeps track of medical data to improve security and display regulatory adherence
- Applies permission-based messaging to share the data you really want to share
- Maintains and enhances cross-industry business without revealing sensitive data
- Connects with international business partners at the vanguard of breakthrough solutions for the healthcare sector
Brennan Bennett, a Chief Strategy Officer at Blockchain Healthcare Review*, has commented, “In reality, you want blockchain to mimic what’s already there i.e. attribute-based access control. With blockchain though, the business logic that governs can have any number of checks and balances (see distributed key access control, quantum key encryption,), creating a whole new spectrum of data sharing.”
He also added that “a few things most people aren’t talking about yet:
- Policy-based access control between business units, either internal or external.
- Node access validation. As blockchain becomes more integrated into infrastructure, nodes, especially those of 2 different networks (i.e. 2 different orgs) will need to be able to validate business policy to share predefined data points of predefined data sets.”

Elements of the Perfect Blockchain Healthcare Model
All blockchains in healthcare must incorporate technological solutions for three vital elements:
- data privacy,
- and access security
A distributed blockchain that contains health records, images or documents, will have data storage implications as well as data throughput limitations.
All members of the distributed network of the healthcare chain possess copies of all blockchain medical records. It is not practical from a data storage perspective.
In order for healthcare software to benefit from blockchain, it would need to work as an access-control manager for health data and records. The user would have access to their data as well as control over how this data will be shared.
Access permissions by the user will be assigned to designate who can access and write data on their blockchain. They would be able to view and audit a log of who accessed the blockchain, including the time and type of data. It will be possible to revoke the access rights to any individual who has a unique identifier using the same dashboard.
Summing Up the Advantages of Blockchain in Healthcare
Among the advantages blockchain provides medical researchers are:
- creation of a single storage location for all health information,
- tracking personal data in real-time
- and the ability to set data access permissions at a granular level
Health researchers need broad and complete data sets so they can better understand diseases, speed up biomedical discoveries, accelerate the development of drugs and provide customized individual treatment plans based on patient genetics, environment, and lifecycle.
So, blockchain definitely has a place in medical software development. Innovecs can act as a reliable partner in implementing this technology into your system or building a solution from scratch to meet your specific requirements.
