ALGORITHM OF ENSURING THE SECURITY OF CONFIDENTIAL DATA OF THE MEDICAL INFORMATION SYSTEM FOR STORAGE AND PROCESSING OF EXAMINATION RESULTS
Abstract
The objectives of the study are to develop and assess the effectiveness of the structure of a cloud platform for storing, processing and organizing medical data, determining a method of protection, in particular, ensuring confidentiality when transferring and storing examination results. To achieve this goal, the tasks of analyzing existing models of information processes and structures in the subject area are being solved, the features of the means for accumulating and processing medical data stored in electronic information systems for patient registration, the architecture of a cloud platform for distributed data storage and an algorithm for ensuring the safety of medical data stored in the cloud are being developed. the platform in electronic form in the form of initial physiological signals (EEG, ECG, EMG, EOG, etc.) recorded during patient examinations; an integrated cloud platform for distributed storage, analysis and systematization of medical data and a security system using the developed protection method are being created; the effectiveness of the proposed algorithm for protecting confidential medical information is analyzed in the context of integration into the developed cloud platform. The proposed method for protecting a medical information system involves the use of an original DICOM file and subsequently a converted PNG image, which is subjected to a pixel encryption algorithm. An algorithm based on chaos theory is used to encrypt the image. The capabilities of chaos systems can significantly increase productivity. Hierarchical division of data streams into levels and standardization of data transfer protocols, as well as their storage formats, allow to form a universal, flexible and reliable medical information system. The proposed architecture has the ability to integrate into existing medical systems. In the course of the work, it was found that the considered protection method is an effective way to ensure the confidentiality of medical system data.
