Abstract
This paper proposes the capturing of IoT data andtheir embedding as metadata in digital snapshots, includingphotos, audios, and videos. Specifically, we focus on IoT devicesbased on Bluetooth Low Energy (BLE) Technology, whichis used for not only data communication but also proximitysensing and is ubiquitous in wearables, smartphones, personaltags, indoor-navigation beacons, and home-automation devices. The IoT metadata can cover different levels, from the radiosignal strength and the media-access controller (MAC) addressto device name, indoor location, temperature, humidity, airquality, and advertising messages. These IoT data can readilyaugment metadata such as timestamp, GPS location, and camerasettings already captured by today's cameras and saved indigital photo files. With such IoT metadata, the user will havemuch richer ways to understand the subject and environmentof the scene being captured by the photo or media, such as thesubject's fitness condition, the advertised events, and the taggedpersonal items at the scene. These metadata will enable newways of searching, querying, and organizing the photos and theassociated objects. Moreover, a novel mechanism we proposeis the ability to pair with a remote device whose identity androuting information is captured as IoT metadata, so that anauthorized user can then pair with it at a later time remotely. We contend that IoT metadata capturing can bring significantbenefits to the users.
