This article takes iPhone track record as an example to explore how iPhone footprint records our life. I. Basic Overview of iPhOne footprint refers to recording the data perceived by the iPhone motion sensor, such as latitude, longitude, speed, altitude and other information. iPhone motion sensors can obtain location information through technologies such as Global Satellite Positioning System (GPS) or Wi-Fi. This information can be displayed on the map app. At the same time, iPhone can also set the switch of track recording in the system settings so that users can choose whether to turn on the function. After turning on the track recording function, the iPhone will record the location of the user's mobile phone in the background, and can provide access to the track record for the application in the system developer interface to facilitate the location-based service of the application. II. Applicable scenarios of iPhone trackThe iPhone track is very helpful to life. Here we mainly introduce its applicable scenarios: 1. Exercise: As we all know, small exercise can promote physical health. By recording the route of commuting, walking or running through the iPhone track, runners can get information about distance, steps, speed and calorie data. Two. Travel: iPhone track recording allows us to record travel routes, scenic spot photos and memories more comprehensively during the trip. The mobile phone that attacks the user can delete the track record of a specific city, province or country in the settings. 3. Family: In order to make daily life more convenient, more and more families will use the location sharing function. Through the track record of iPhone, you can share your location with your family to determine whether you arrive at your destination on time or find each other.III. While the convenience brought by the data privacy risk trajectory record, it also brings data privacy risks. The attacker can obtain the user's location data from the mobile phone, so as to understand the user's specific location information. If the track recording (i.e. location sharing) function is abused or hacked, it will bring potential privacy risks to users. In order to protect users' privacy, we should be more careful and pay attention to protecting our privacy when turning on iPhone track recording. IV. Regarding the settings of iPhone track records, we can find the button of "Important Location Move" or "Location Sharing History" in Settings-->Privacy-->Location-->System Services. These options are used to set the track record of iPhone. In these options, users can choose whether to turn on the track recording function and control the application that uses track recording.If the user disables the location service of the running application in the settings, the application will not be able to access the user's track record. In addition, users can also delete historical location data as needed to protect users' privacy. Summarize that all aspects of our lives are included in the iPhone track record, from our daily life to work and travel. Track records can provide us with specific location data and help us understand what we have experienced every day. However, these sensitive data are easy to be used or stolen, so we should protect and manage these data to avoid data abuse to the greatest extent. In the process of daily use of mobile phones, we need to carefully and appropriately control the iPhone track record and regularly delete historical location data to ensure the user's data security and privacy.
