Аннотация: (English) The proposed technology for organizing an information flow protection system within a corporation ensures multi-level system security, including real-time tracking of the status and location of each disk available within the corporation. Applying the proposed encoding methods for protecting information on mobile external storage devices is expected to achieve the same advantages as when used on optical storage media and information carriers. Thus, based on similar solutions, at least two projects with numerous applications can be developed: ● A technology project for encoding optical disk-based storage media, which includes an appropriate analytical-sensor device that, in turn, can have multiple applications across various fields and industries. ● A project for encoding and protecting information on mobile external storage devices, which includes an appropriate mobile or stationary sensor-based measuring, analytical, and comparative device, also featuring multiple applications and design models.
