Under the background of electronic medical data, doctors use electronic images to replace the traditional film for diagnosis, and patients can view examination images at any time through various electronic means. The storage and frequent reading of massive data bring new challenges. Given the characteristics of the size and quantity of image files generated by different examination types, different merging strategies are proposed to improve the storage performance of the files; according to the characteristics of medical data with examination as the basic unit, a two-level model combined with medical imaging information is proposed. The indexing mechanism solves the problem that SEQ files cannot be read randomly without an index; given the time characteristics of data access, an improved 2Q algorithm is proposed to cache the prefetched files and the read files in different cache queues, which improves the efficiency of file reading. In the experimental comparison, the proposed algorithm surpasses the baseline method in storage and access performance.

Compliance Audit

Complying with privacy in multi-jurisdictional health domains is important as well as challenging. The compliance management process will not be efficient unless it manages to show evidences of explicit verification of legal requirements. In order to achieve this goal, privacy compliance should be addressed through “a privacy by design” approach. This paper presents an approach to privacy protection verification by means of a novel audit framework. It aims to allow privacy auditors to look at past events of data processing effectuated by healthcare organisation and verify compliance to legal privacy requirements. The adapted approach used semantic modelling and a semantic reasoning layer that could be placed on top of hospital databases. These models allow the integration of fine-grained context information about the sharing of patient data and provide an explicit capturing of applicable privacy obligation. This is particularly helpful for insuring a seamless data access logging and an effective compliance checking during audit trials

Federal Center

The features of interaction between state authorities and municipalities (a set of local self-government bodies) of closed administrative-territorial entities (ZATO) in the field of land use are considered. The article substantiates the opinion that this interaction is carried out to a large extent within the framework of a two-level model of legal relations “the federal center — the municipalities of the closed city”. In cases specified by legislation, this model includes another level of government — regional government bodies. Using the methods of dialectical cognition, as well as the general theory of constructing social and legal structures, the author substantiates and proposes a number of organizational and legal measures aimed at increasing the efficiency of interaction between public administration bodies and municipal authorities of closed administrative administrative units in the field of land use, as well as solving specific problematic issues arising in the process of this interaction.
