The problem JEEVAN solves

As we all know the major threat nowadays is related to organ trafficking and for that there is no system to register the complaints on ,apart from this the preliminary process of organ transplant is itself quite cumbersome.Moreover, the records are also prone to cyber threats and there is no portal for the recipients to interact with to resolve their queries. With the current organ donation system in India, many a times the recipient who is placed higher in the queue to receive an organ is denied an organ due to malpractices of influential people, our system aims to combat that by maintaining a centralised list of recipients for everyone to see, to ensure that a person placed below another in the priority queue doesn’t receive an organ before them.
