使用無線感測網路對行動裝置功能實施抑制行為之研究

Abstract

無線感測網路(Wireless Sensor Networks) 技術常用於環境變數的分析與收集，例如溫度、壓力、亮度等等。這些量測的資料可根據事先定義的規則，採取適當的行為。而且這些Sensor感測元件有體積小、耗電少、及可方便攜帶的優點，可長時間使用。 多功能的行動裝置(如手機、數位相機) 帶給人類許多便利性，卻也帶來侵犯隱私,洩密等疑慮，例如：在公共洗手間或更衣室進行偷拍、私下錄音等嚴重侵犯他人隱私的案件不斷產生，其不僅侵犯人權，且造成社會的不安和混亂。另外，商業機密資料(如智慧財產權)若遭商業間諜利用行動裝置惡意擷取，將大幅減損高科技廠商之競爭力。 本研究提出發送抑制功能的命令給無線行動裝置，以關掉某項功能。這抑制功能的指令可由XML (Extensible Markup Language) 訊息透過無線感測網路送出，亦可是一個特定抑制的圖形或影像、或特定波長(850~1550 奈米)的不可見光訊號。

舉例來說，進入禁止拍照的區域如公共洗手間、更衣室、工廠、軍事重地等等。感測元件發送抑制照相功能的指令給行動裝置如手機PDA， 行動裝置接受到指令，會自動關掉手機照相功能。再者，如果進入吵雜的環境， 感測元件發送調大音量的指令，適時反應現在環境的變化，反之亦然。如果進入戲院、音樂廳、會議室，則手機轉為靜音或震動模式。一旦離開禁止區域，則解除抑制功能指令。

Wireless sensor networks are normally used to collect and analyze environment variables like temperature, pressure, luminosity, and so on. The collected data can be used to trigger some actions according some pre-defined strategies. These sensor nodes have the advantages of small size, low power consumption, and portability features. Mobile devices (such as handsets and digital cameras) bring us convenience, but they also cause privacy concerns. For instance, to carry on in secret photographs surreptitiously or sound recordings in public toilet or the changing room. It is serious to encroach upon other people’s privacy in private. Moreover, if the commercial secret restricted data picked up by commercial spies using mobile devices, it will largely damage the business profit and decrease of competitive ability. In the research, we propose to use sensor networks to broadcast inhibition commands to mobile devices so as to inhibit some functionalities of these mobile devices. The inhibition commands can be conveyed via Extensible Makeup Language (XML) messages and transmitted by wireless sensor networks. It can also be a particular recognizable image or figure or some invisible light within some specific wavelength (850~1550 nm). For example, when a user enters a public region (such as a public toilet / dressing room / factory/ military classified place/ hospital), the sensor network can send photography forbidding messages to his/her mobile devices. After parsing these messages, the mobile devices automatically disable these requested functionalities. As another example, in a noisy area, the sensor networks inform mobile devices to adjust their sound volume. On the contrary, when entering a theater, museum, hospital or meeting room, the sensor networks request mobile devices to turn off sound mode. When the user leaves the inhibition region, the mobile devices will enable these disabled functionalities.
