Identity and Vulnerable Populations

Specific Problem

Being able to efficiently track and record the immunization/vaccination history of refugees coming into a country, especially in war torn countries or refugees escaping from their country due to turmoil (whether it is for government, war, religious, or any other reason).

Why is blockchain needed to solve this problemn?

Refugees especially from war torn countries come into a new country, sometimes without having proper identification and if they do, may not even have medical records with them. At the same time, how does a government or an existing establishment know that the refugees' medical records are legitimate records and that they have not been altered in anyway? Blockchain can be used in order to permanantly record the medical history of refugees and give a unified platform for different medical institutions or different countries that allow them to check the history of those that come into the new country. This is especially more critical in war torn areas or in areas where medical records are not used to store someone's medical or vaccine history.
The blockchain can also be used as a way to restrict people coming into the country. In the current status of the healthcare industry, it is common for patients to have hard copies (or paper copies) their vaccination history. These paper copies can be easily forged and changed. Furthermore, they can easily lose these documents or they can be stolen or they may not deem these specific papers as important for them and when they do find out that it is important, it's too late.

Size of the market

The size of the market for this product is relatively small as this solution is fairly for medical/identity purposes. However, the target market will be towards non profit organizations that deal with vaccinations and refugee identity and as well as governments of countries as they need to be aware of refugees entering into their own country. The size of the potential users for this product however is 7 billion, everyone in the entire world as this blockchain solution can be applied and used for everyone. Practically speaking, the solution will be used in third world and war torn countries. Given the inefficiencies in the Western world’s healthcare, this solution could also be used by first world countries.

Other solutions

Pokitdok’s prototype blockchain solution ( is not necessarily a competitor or complete substitute for our solution but it is possible for it to be repurposed to give the same results

UN + Microsoft + Accenture
The United Nations launched a prototype blockchain experiement for Syrian refugees in the summer of 2017, recording their identities onto the blockchain. With the help of Accenture and Microsoft, they were able to scale the solution and use it for other countries (refugees). The United Nations also created the ID2020 group to push this effort forward. Although this project specifically deals with refugees and identity, it can most likley be extended for vaccination records.

Health Wizz A direct competitor to our solution, Health Wizz has created a medical records history application that implements blockchain technologies

Week 2 Deliverables


Clients of our solution are governments of countries, more specifically those of third world countries where keeping vaccination history is a problem.
Users of the solution will be doctors, nurses, first aid responders, health care administrators and as well as refugees or patients coming into a new country.

Product's Value Proposition

  • An easy to scale and easy to deploy solution that reduces the inefficiencies of the current medical process when taking in new patients/refugees from other countries
  • Allows doctors, nurses, administrators, and healthcare organizations to keep a permanent, immutable medical vaccination history of refugees
  • Considerably reduces the amount of paper work needed which increases turn-around time in processing a refugee
  • Reduces existing painpoints for refugees and medical personel (language barriers, forgotten papers)
  • Refugees in war torn countries do not need to keep the documentation anymore

Risks Associated With solution

With new technologies, there is always risks involved, especially during their deployment and their security. An individual's medical records is very, very sensitive information and should not be touched by anyone else unless allowed by the person. With blockchain, every transaction is out in the public, but since the proposed solution is within its old private blockchain network, the only people allowed to see the transactions are the patient's themselves and the doctors/nurses that administered the vaccines. There is always a risk that a malicious user can access the network from outside whether or not being from social engineering, or a doctor, nurse, or administrator leaving their password out in the open. It is imperitive that everyone using the blockchain technology adhere the already existing, and strict security guidelines and practices that are in place in the IT industry.

Impact of solution/Criteria

Once successfully deployed, this will reduce the inefficiencies and massive overhead that is incurred when processing refugees, especially those in war torn countries. It can take months to fully process a refugee and making sure they have a vaccination history adds to that process. By implementing the solution, this can reduce the time from months to weeks.
