Abstract (English): ABSTRACT of the dissertation work by Altynbek Serikovich Seitenov on the topic « Telemedicine for improving health and social care innovation technology » submitted for the degree of Doctor of Philosophy (PhD) under the educational program «8D06103 - Information Systems» Relevance of the research. The development of the healthcare system in the Republic of Kazakhstan is impossible without the implementation of innovative digital solutions, as reflected in state digitalization programs and regulatory documents in the healthcare and social protection sectors. With the growing volume of medical information, the expansion of remote forms of medical care, and the need to improve accessibility, the development of telemedicine plays a crucial role as a priority area of the industry's digital transformation. Telemedicine technologies enable remote consultations, patient monitoring, and the exchange of medical data between medical organizations, thereby increasing the efficiency of the healthcare system and reducing the burden on medical personnel. At the same time, the effectiveness of telemedicine services directly depends on the reliability of the architecture of medical information systems and the level of protection of personal medical data. Traditional centralized medical information systems, widely used in practice, do not always provide the required level of security, transparency, and access control. The presence of a single point of failure, limited audit mechanisms, and the inability to cryptographically verify transaction records create the preconditions for leaks, substitution, and unauthorized access to patient personal data. These problems are particularly acute when telemedicine is integrated with external digital services and social security systems. The relevance of this research is heightened by increasingly stringent regulatory requirements for medical data protection. International regulations such as GDPR and HIPAA, as well as Kazakhstani legislation on personal data and healthcare, establish mandatory requirements for operational transparency, maintaining access logs, proving the legality of information processing, and expanding patient rights to control their own data. However, existing medical information system architectures do not fully implement these requirements, creating a regulatory and technological gap. With cyber threats and information security incidents growing in the healthcare sector, the implementation of new architectural approaches is particularly important. A promising approach is the use of blockchain technologies and cryptographic methods to create a distributed layer of trust and immutable audit trail. Using a hybrid architecture that combines centralized storage of medical data and decentralized access control mechanisms ensures operational transparency, data integrity protection, and controlled access without transferring medical information to a distributed ledger. The study is further relevant given the need to enhance the patient's role as an active participant in the digital healthcare process. Current telemedicine models are focused on providing patients with consent management mechanisms, access control, and tracking of transactions with personal medical data. Implementing these capabilities requires the implementation of tokenized access modules and cryptographically verifiable permission management mechanisms. The relevance of this study is due to the need to develop a hybrid telemedicine architecture that ensures secure processing, storage and exchange of medical data, in line with modern regulatory requirements and the challenges of digitalization of healthcare in the Republic of Kazakhstan. The aim of the study was to develop and evaluate a hybrid architecture for a telemedicine system integrated with blockchain technology, aimed at ensuring secure storage, management, and controlled access to personal medical data. Based on the purpose of the dissertation, the following tasks were set: To study modern models of telemedicine and approaches to the application of blockchain technologies in healthcare and social protection ; To investigate the vulnerabilities of architectures of centralized medical information storage systems ; Develop an architectural model of a hybrid system; Implement a software prototype of the system, including a user interface, a control module and storage of medical data ; Conduct an experimental and comparative evaluation of the effectiveness of the developed prototype. The object of the study is the processes of processing, storing and exchanging personal medical data in telemedicine systems. The subject of the research is a hybrid architecture of a telemedicine system based on the integration of a medical information system and blockchain technology, providing access control, security and control of operations with personal medical data. Research methods include architectural design methods for medical information systems, methods for analyzing and modeling the processes of processing and storing medical data, cryptographic methods for information protection, tokenized access control (TAC) mechanisms, methods for forming an access context, and experimental validation of architectural solutions. Software. The methodological basis for developing algorithms and software is provided by the use of Python, FastAPI, Node.js , PostgreSQL , Hyperledger Fabric, as well as testing and performance analysis tools. The main results to be defended: Development of a hybrid architecture for a telemedicine system based on the integration of a medical information system and blockchain technology; Implementation of a security and access control module based on tokenized mechanisms and cryptographic verification of access rights; Development and experimental evaluation of a software prototype of a telemedicine system supporting secure exchange of medical data and audit of operations. Scientific novelty: A hybrid telemedicine architecture has been developed for the Republic of Kazakhstan based on the integration of medical information systems and blockchain technology; A mechanism for managing access to medical data based on tokenized metadata and cryptographic verification of transactions has been developed. Theoretical significance of the study. This study substantiates a hybrid telemedicine system architecture based on the integration of a medical information system and blockchain technology, and develops approaches to access management and transaction auditing using tokenized metadata and cryptographic mechanisms. The proposed solutions, complementing classic models of centralized medical information systems, expand the theoretical basis for building secure and trusted telemedicine platforms and enable the formalization of access control and transaction transparency as a separate architectural layer. The theoretical basis is the concept of patient-centric medical data management, which views medical information as a dynamic object, access to which is determined by context, rights, and terms of use. This paradigm allows the telemedicine system to be interpreted not as a static data repository, but as a manageable and verifiable digital environment for interaction between healthcare participants. Practical significance of the study. The results of this dissertation allow for the development and implementation of a hybrid telemedicine information system that ensures secure processing, storage, and controlled access to personal medical data. The implementation of the proposed architecture and security module is aimed at enhancing information security, operational transparency, and regulatory compliance in the provision of telemedicine services, as well as improving the reliability and quality of digital medical services. The implementation of the developed information system is confirmed by a certificate of implementation at the Aisera Clinic medical institution . Implementation of results.

The dissertation is written in Russian and consists of an introduction, four sections, a conclusion, a list of references, and appendices. The first section of this dissertation examines modern approaches to telemedicine and medical information system architectures, as well as key digital security threats. The limitations of traditional centralized models, including a single point of failure, the lack of immutable and verifiable audit trails, limited access control mechanisms, and noncompliance with international and national regulatory requirements, are analyzed. Special attention is given to the analysis of information security incidents in healthcare. It is shown that existing research primarily focuses on individual aspects of data protection and does not formulate comprehensive architectural solutions. A comparison of the identified advantages and limitations substantiates the need to develop a hybrid telemedicine system architecture that integrates a medical information system and distributed access control technologies. The second section of the dissertation formulates the theoretical and methodological prerequisites for building a secure telemedicine architecture. It examines the limitations of centralized medical information systems in the face of growing IoMT infrastructure and data volumes. It analyzes the potential of blockchain technology, smart contracts, and distributed audit trails to ensure immutability, traceability, and trust. It also identifies the regulatory and technical limitations of fully decentralized solutions. A comparison of the advantages and disadvantages of existing approaches substantiates the feasibility of a hybrid architecture combining centralized storage of medical data with distributed mechanisms for access control, cryptographic verification, and regulatory compliance. In the third section of the dissertation, a hybrid system model combining a centralized medical information system and a permissioned blockchain infrastructure is developed based on the conceptual and architectural design. It is demonstrated that the use of distributed event logs, tokenized access control, and cryptographic verification ensures auditability, operational transparency, and control over the use of personal medical data. The developed architectural diagrams, ERD model, and component interaction algorithms confirm the feasibility of separating functions between the on-chain and off-chain layers, maintaining performance and regulatory compliance. It is noted that the proposed architecture complies with GDPR, HIPAA, and international information security standards and can serve as the basis for further software implementation of scalable telemedicine platforms. The fourth section of this dissertation implements a software prototype of a hybrid telemedicine system and conducts its experimental evaluation . The paper describes the stages of developing a centralized medical information system, deploying a permissioned blockchain layer, and implementing secure access control mechanisms based on tokenized permissions and Zero-Knowledge Proof. A multi-criteria evaluation methodology for architectural alternatives, including quantitative and categorical indicators, is used, with the CRITIC method for determining criterion weights. The experimental results demonstrate the advantage of a hybrid architecture, which provides a balanced combination of performance, audit transparency, cryptographic security, and regulatory compliance, confirming its practical applicability and potential for implementation in telemedicine systems.
