In order to collect user information and deliver advertisements, the server often needs all kinds of information from mobile phone users’ devices and APPS. Here is how to obtain all kinds of information:

Advertising space identifier: All App will take on the same equipment to the same value, is Apple specifically to the advertising provider used to track the user, the user can reset in privacy Settings | | advertising tracking this id value, or to limit the use of this id, so id may take less than the value, but fortunately, the default is to allow the tracking of Apple, And the average user does not know there is such a setting, so basically used to monitor the promotion effect, is too much poke

UUID is an abbreviation of Universally Unique Identifier. It allows all elements in a distributed system to have unique identification information, without the need for the identification information through the central control terminal. This way, each person can create a UUID that doesn’t conflict with anyone else. In this case, there is no need to worry about name duplication when the database is created. Apple recommends using UUID to generate unique identification strings for applications.
