| Summary: | 碩士 === 國立清華大學 === 資訊系統與應用研究所 === 104 === 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.
