In the era of the widespread use of mobile gadgets, it is becoming increasingly difficult for a person to defend himself from total surveillance and ubiquitous control. Researchers from California, working at the International Institute of Computer Science, found stunning facts. It turns out that over 17 thousand Android applications are closely monitoring the actions of users. The technology for tracking the owner of the gadget with the installed application uses the Advertising ID, according to Google, which is the only provider of user data for developers. However, California engineers concluded that over 65% of applications receive unique personal information that can identify the user. No lawsuits related to the loss of personal data can stop developers from hunting for confidential information conducted in violation of Google’s policies. In fact, all application settings affect only restrictions on the transfer of information to an advertising identifier. However, any other confidential information can be obtained by the application, regardless of the client’s desire. Enthusiasts have found that the most popular applications, such as the Angry Birds game, Audible audio books, Battery Doctor and Clean Master applications, which have been installed on more than 1 billion devices. The Google team has not yet responded to research data.
