In response to the rise of the era of Internet of Things, worldwide companies in the fields of telecommunications, software, and hardware, have invested in various products and researches in relevant applications. There are many applications and breakthroughs being realized on the techniques from telemedicine, over the development of medical devices and equipment, smart wearable devices, to medical care. For medical equipment and wearable technology, there has developed many embedded medical monitoring devices in the relevant markets. However, the specification to the market-leading standard has not yet emerged to fully satisfy the justification of communication methods and interface design. Because the diversity of communication interfaces used for various devices, the networking architecture and the associated infrastructures are difficult to fully construct. Although the easier usage and efficiency of the medical services make patients be getting better through new techniques, the weakness of privacy security will also expand as well. In order to overcome the predicament, the design of a comprehensive communications architecture that offers sufficiently security and enables medical privacy protection has played an essential role. This article offers a framework of medical privacy protection by implementing with the STM32 series 32-bit processing core based on the ARM reduced instruction set architecture. The proposed framework utilizes the communication protocol of traditional industrial instrument Modbus to process serial data formats, which implements software layer data exchange and packaging. And through relevant software and hardware planning designs, we used UART, RS485, SPI and other hardware interfaces to achieve common communication interface connections. The adopted devices were also applying on integrated W5500 network chip to provide wired Ethernet interface and subsequent communication channels for achieving networking functions and communication data forwarding, and further the data encapsulation at level of the on the network forwarding. Therefore, in order to achieve the security and privacy of system information flow at network levels, further effort has been made on bridging with the encrypted network protocol Websocket, hence the information security would be guaranteed as a result. |
