透過行動裝置拍攝圖像之物聯網元數據創建系統及其應用

此篇論文提出以數位快照的方式收集物聯網資料來作為元數據的內容儲存在相片或是影音中。尤其我們專注在使用藍芽低功耗技術的物聯網裝置上,這些裝置不只用來做資料的傳輸也可以支持近距離傳感而且在穿戴式、智慧型手機、私人的裝置、市內導航感應器以及家庭裡自動化的裝置都無所不在。物聯網元數據可以涵蓋很多不同的層次,像是無線電的信號強度和媒體存取控制位址到裝置的名稱、室內位置、溫濕度、空氣品質到廣播的資料。這些物聯網資料可以很輕易地在元數據新增像是時間戳記、GPS位置和原先拍攝時相機原有的設置資訊等,並將這些數據存在數位相片檔案內。有了這些物聯網元數據,使用者將可以有更多的方式去了解所拍攝的相片場景或其他媒體中的物品和環境的資料,像是物品的詳細資訊、廣播的事件或是在場景中的私人標籤。這些元數據提供了一個新穎的方式來搜尋、訪問並組織照片和相關的物品。此外,我們提出的這個新的機制是有能力去與遠端的裝置去做配對,前提是這些裝置的身份和路由訊息當初有被當作物聯網元數據收集起來,所以經認證過的合法使用者可以與遠端的裝置配對並獲取新的資訊。我們認為收集物聯網元數據可以為使用者帶來顯著且有意義的好處。

This thesis proposes the capturing of IoT data and their embedding as metadata in digital snap- shots, including photos, audios, and videos. Specifically, we focus on IoT devices based on Bluetooth Low Energy (BLE) Technology, which is used for not only data communication but also proximity sensing and is ubiquitous in wearables, smartphones, personal tags, indoor-navigation beacons, and home-automation devices. The IoT metadata can cover different levels, from the radio signal strength and the media-access controller (MAC) address to device name, indoor location, temperature, hu- midity, air quality, and advertising messages. These IoT data can readily augment metadata such as timestamp, GPS location, and camera settings already captured by today’s cameras and saved in digital photo files. With such IoT metadata, the user will have much richer ways to understand the subject and environment of the scene being captured by the photo or media, such as the subject’s fitness condition, the advertised events, and the tagged personal items at the scene. These metadata will enable new ways of searching, querying, and organizing the photos and the associated objects. Moreover, a novel mechanism we propose is the ability to pair with a remote device whose identity and routing information is captured as IoT metadata, so that an authorized user can then pair with it at a later time remotely. We contend that IoT metadata capturing can bring significant benefits to the users.
