Smart Watch is a new wearable device, which contains a large number of new design conceptions, including the real-time detection of vital signs sensors, and wireless communications which send real-time monitoring of data to other devices. Its appearance reflects the rapid development of wearable devices, but also reflects the application of wearable devices will be step by step toward people''s lives. It has the general function of watch. In addition, it has advanced sensors, including temperature sensors and humidity sensors. When it detects the change of temperature or humidity, it will be real-time upload data to the smart phone client. And it''s smart phone client, it can ensure that the basic function of the smart watch, and optimize the user experience of smart watches. It will set properties for the watch, and it will also collect data from the smart watch, and transmitted to the server, for the purpose of monitoring the cloud. This design will be constructed mainly on

可穿戴设备面临着个人隐私泄露风险,黑客远程攻击风险,政府、军队等办公网络核心数据泄露风险,并进一步引发国家安全问题。究其根源,主要是由于系统漏洞和恶意软件、Wi Fi热点安全等问题引起的。据此,本文提出了我国应对的三点建议：提高对可穿戴设备信息安全的重视;加强可穿戴设备信息安全防护技术研发和体系建设;引导用户增强信息安全意识。

We found that wearabIe devices are faced with many risks, such as the risk of personaI privacy, hackers remote controI, and the core data Ieakage of government, miIitary and other of ice network. These risks even Iead to the chaI enge of nationaI security. The causes are mainIy the system vuInerabiIities, maIware, and WiFi security probIems. In the Iast part of the paper, we put forward three suggestions. First, we shouId improve our recognition of wearabIe device security. Second, the information protection technoIogy of wearabIe device shouId be researched, and information security system construction shouId be deveIoped. Third, the government shouId guide the user to enhance awareness of information security.
