AI Technical Summary

Technical Problem

Existing medical image transmission solutions lack the ability to dynamically perceive device location and usage time windows, resulting in unauthorized devices being able to access sensitive data. Furthermore, they cannot dynamically generate file views based on medical staff ranks and patient privacy levels, posing risks of data tampering and unauthorized browsing.

Method used

By embedding a spatiotemporal fence verification mechanism for two-way identity authentication, and using a private key to jointly sign the challenge number, timestamp, and location coordinates, sessions are established only within a preset time window and geographical radius. Data is transmitted through a high-bandwidth encrypted channel, and file views are dynamically generated to achieve fine-grained access control and fragmented encrypted transmission.

Benefits of technology

It effectively prevents the risk of data leakage caused by lost or out-of-bounds devices, ensures the integrity and security of data transmission, and achieves full-chain security protection from access to destruction.

Abstract

The application discloses a medical image transmission method based on a wireless U disk and particularly relates to the technical field of medical information, and comprises the following steps: step S1: a wireless U disk periodically broadcasts a device beacon through a low-power wireless communication module; and step S2: after two-way identity authentication, the wireless U disk and a medical terminal negotiate to establish a high-bandwidth encrypted data transmission channel; the application embeds a time-space fence checking mechanism into a two-way identity authentication process by executing a program in a memory through a processor, jointly signs a challenge number, a time stamp and a position coordinate by using a private key, and calculates a time and space compliance factor, so that the device can only establish a session within a preset time window and a geographical radius, thereby blocking the data leakage risk caused by device loss or border crossing from the source.
