These are not just logs of our activities, they create digital files that trade between companies and are used to make inferences and decisions that affect our lives and our lives. More importantly, this usually happens with our consent or control. The new, sophisticated approach built into your smartphone makes it easy to track and monitor our behavior. Lots of information can be collected from our smartphones, whether they are actively used or run in the background. This information may include biometric data such as our location, Internet search history, communications, social media activities, financial status, and fingerprints or facial features. It can also contain metadata, that is, information about the data, such as when the text message was sent and the recipient.
Each type of data can reveal our interests and preferences, opinions, interests and social interactions. For example, a study conducted by the Massachusetts Institute of Technology shows how to use email metadata to map our lives and demonstrate the dynamics of our professional and personal networks. These data can be used to infer personal information, including personal background, religion or belief, political opinions, sexual orientation and gender identity, social relations or health. For example, it is possible to infer our particular health condition simply by connecting points between a series of phones. Different types of data can be combined and linked to build up our comprehensive profile.
A recent study found that seven out of ten smartphone apps share data with third-party tracking companies such as Google Analytics. Data from many applications can be linked in a smartphone to build a more detailed portrait of the user, even if permissions for individual applications are granted separately. In fact, smartphones can be converted to surveillance equipment. The result is creating and blending digital footprints to gain insight into your life. The most obvious reason companies collect personal information is to profitably provide targeted advertising and personalized service. Some targeted ads, while potentially ghastly, are not necessarily problems.
