Аннотация:Recently, the growing popularity of mobile content sharing applications has become increasingly noticeable. Applications that enable simultaneous viewing of presentations are becoming particularly relevant. Many existing services for these events often require users to register and authenticate. These actions force the user to leave their personal data on certain resources, which leads to a loss of anonymity and privacy. Such actions by various services are justified by several factors, such as the use of an auxiliary server to synchronize user actions and establish connections between the mobile devices of event participants. However, the problem of simultaneous viewing of presentations can be implemented without any server infrastructure and without initiating communication between user’s mobile devices. In this paper, we propose a more secure architecture for content sharing system that is based on network spatial proximity technology. The presented approach is implemented as a mobile application for Android OS. Additionally, an experiment was conducted to compare the data transmission protocol developed by the author across different BLE versions and various advertising and scanning parameters. The author describes a further plan for the development and enhancement of the proposed architecture.
