Our iosapp has been cracked. Because on some jailbreak machines, hackers have modified UDID, IMEI, IDFA, idfv, serial number and other system information that you can think of. And it looks random. We want to get the unique identification code of the machine, I want to get these iPhones with cracked apps installed to ban the devices. So I have two questions. 1.My current idea is to generate the unique identification of iPhone by calling the private API to get the hardware information. 2. If you have a better way to identify these devices, please let me know, thank you very much
If you use any private API, it may get rejected by Apple.
You can refer these options to get the unique device. https://codeburst.io/unique-identifier-for-the-ios-devices-590bb778290d
