In recent years, data leakage incidents have been frequently exposed, and personal privacy protection has become a major issue. To explore the laws of data leakage and solve practical problems, the reasons for data leakage and the evolution of players’ strategy in the game are discussed. After sorting out the interest relationship of data leakage incidents, a three-party evolution model of invaders, operators, and regulators is established to analyze the evolution path from the perspective of a single party. The Lyapunov theory is used to analyze the stability of equilibrium points of the system and then verified by MATLAB simulation. The influence relationship of various parameters on the system is analyzed. Finally, the ideal state is defined and the system is attempted to be modified. The results demonstrate that under the current system, the evolution direction cannot be changed by the initial intention of players. The game result will eventually form a situation with a strong attack from invaders, advanced defense from operators, and extensive management from regulators. The attack level can be reduced by adjusting the controllable parameters, modifying the evolution path, and calculating the parameter range.

“…This phenomenon also applies to other digital standards that are used in the processing of information in electrical form [16]. In any case, the sources of undesirable signals must be protected by applying solutions that prevent the effective conduct of the infiltration process [6,[17][18][19].…”

Electromagnetic Safety of Remote Communication Devices—Videoconference

Devices powered by electricity become sources of electromagnetic emissions in the course of their operation. In the case of devices oriented to process information, these emissions can have a character of revealing emissions, i.e., those whose reception and analysis allow for remote reconstruction of related data. The best known example of this phenomenon is the formation of revealing emissions during the operation of imaging devices: monitors, projectors or printers. Increasingly more often, these components are used for communication in the form of videoconferences with other network users. The article presents the result of tests and analyses of threats related to the use of such solutions (monitors, personal computers, VoIP terminals) for the confidentiality of conversations and the data presented during them. The focus is on video signals; however, the potential possibilities of revealing speech signals were also indicated. Such phenomenon causes a huge threat to data confidentiality because the combination of graphics and sound can undoubtedly contain much more information about the protected data than just graphics or sound separately. The presented results of analyses apply to graphic data, possibilities of non-invasive acquisition of such data, similarity of images and of patterns and reconstructed image and image recognition. The results indicate that there is still a risk of loss of data confidentiality due to a phenomenon of an electromagnetic leakage, and specialized instrumentation is not required for its interception under favorable circumstances. This may particularly apply to audio data that may be accidentally received by home radio receivers. In particular, the presented results of analyses apply to a Special Issue of Symmetry which is characterized by security and privacy in communication systems and networks, signal processing, video and image processing, multimedia communications and electromagnetic compatibility. All these scientific and technical areas have either symmetrical or asymmetrical approaches, and they have to be taken into consideration as a whole in order to choose the best combinations to protect processed information.
