Android和iOS开发者! (希望Google员工或Appler?)Google的Google广告ID(GAID)和Apple的IDFA可能发生碰撞?

我想通过广告ID跟踪广告的手机, 但我遇到了一个重要问题。

Can GAID and IDFA be the same between different two devices in real world?

苹果和谷歌似乎没有发布算法生成的ID, 但我们默许开发商思考的十六进制32位数字是随机生成的,所以 会出现冲突。

我想确保没有碰撞发生!

哦,在现实世界中没有碰撞。这可能是最好的答案?

看线条引用。

Google Advertising ID (AAID) for Android devices 
Inventory bid requests from Android devices pass the AAID, 
which provides the same type of device-specific, unique, 
resettable ID for advertising as the IDFA. 
The ID for tablet devices with multiple users may also be unique per user. 

All of the features, encryption and technical details for IDFA also apply to the advertising ID.

嗨,好奇同样的问题选址。你是否最终确定了这一点(以一种明确的方式)?谢谢! – user31415

这两个id都是32个十六进制数字(Rumor说GAID是小写,IDFA是大写)。通过思考简单的情况,新创建的id的碰撞概率为1/16^32。据说不会有碰撞的机会。 – user927387
