People can, with the help of the apps, such as Truecaller, Sync.me and CM Security, to see by whom they are called if they have a phone number do not recognize. This works as a sort of reverse phone book, where you do not have the phone number with a name, but a name to the number.
Before this kind of apps can be used, people need to their list of contacts to upload. The companies behind the apps have a massive database collected. One of them even claims about two billion songs. Often people do not even know that they are included in the database and they have no permission to do so. Privacyorganisaties in Great Britain go to do research for the apps.
