Apps in iOS 5, the idenitificatienummer of iPhone and ipad, the UDID, not more request. That claims TechCrunch. This would mean that large databases of advertising companies with usage data in one fell swoop become worthless.
In the documentation of the beta versions of iOS 5 is that the function ‘uniqueIdentifier’, the function that the UDID of an iPhone, iPod touch, iPad or iPad mini can be requested, ‘deprecated’, reports TechCrunch. Apps use UDID’s to databases of advertising companies user data. On the basis of these data are shown ads on the basis of data from the user. It may include location data and data about use of apps.
Instead, would apps, an own identifier to have to make to the hardware to recognize and ads to match. The measure would have major consequences for ad networks. These networks collect with the help of apps, a large amount of data about users. If the feature is not in iOS 5, is after an update that database become worthless.
It is still unclear whether the function or not in iOS 5. Developers who respond under the article from TechCrunch say that they still make use of apis in iOS 3.2 ‘deprecated’ were declared. Apple would like to indicate that the ‘uniqueIdentifier’function may be in future iOS versions does not return and that developers therefore better already own identificatiefunctie could build.
