Ways of Unauthorized Access to Medical Data and Approach to Organize Secure Access using Blockchain Technology

The introduction of digital technologies into medical institutions promises great prospects, allowing of improving the quality of treatment and radically changing the approach to early diagnosis of dangerous diseases. However, this progress has a dangerous side effect - the risk of information security. The system of differentiation of access in many systems of medical establishments is not reliable due to the lack of active ways of cryptographic protection of information. In addition, most systems do not provide mandatory access control, and accordingly do not allow you to differentiate computer resources by secrecy and category. In some cases, it is not possible to set passwords to access some of the most important computer resources. Cryptographic protection is the basis for protecting information from theft. The disadvantage of modern diagnostic center systems is the high speed of cryptographic transformations, which forces users to abandon the encryption function.
