I don’t know if you have seen such news before: IOS 14.5 has added the application tracking transparency privacy function. With this function, users’ privacy information will not be leaked, which can effectively block the push of accurate advertising.
This function is happy for users and a disaster for advertisers. Losing the ocean of big data means losing very big interests. In order to prevent this from happening, manufacturers will try their best to fight apple.
According to the grapevine, most domestic Internet technology companies have jointly developed a response scheme called CAID. After this scheme is put into use, even if Apple’s IDFA cannot be used, it can easily track the used privacy information and accurately put advertisements.
In fact, their cheating scheme has long been seen and warned by apple. If Apple finds that the app that needs to be updated in the apple store supports CAID, it will reject the update request of such app. After being rejected to update, cheating is cool.
