关于苹果备受争议的设备上CSAM扫描仪，有很多讨论。该公司似乎听到了一些问题，因为它决定推迟推出，直到能够做出更多改进。

苹果的csam扫描技术

苹果公司上个月首次宣布对儿童性虐待进行扫描，但遭到了一些抵制。当图像上传到云端时进行扫描并不是什么新鲜事，但苹果表示，它打算在用户的设备上对扫描图像进行散列处理，一些人认为这是对隐私的侵犯。

在Apple.com上的一份声明中，该公司透露了推迟扫描技术的决定，直到能够做出更多改进：

Previously we announced plans for features intended to help protect children from predators who use communication tools to recruit and exploit them and to help limit the spread of Child Sexual Abuse Material. Based on feedback from customers, advocacy groups, researchers, and others, we have decided to take additional time over the coming months to collect input and make improvements before releasing these critically important child safety features.

苹果表示，其CSAM扫描技术实际上对用户来说比上传到云端后进行扫描更好。以下是公司对流程的描述：

Before an image is stored in iCloud Photos, an on-device matching process is performed for that image against the known CSAM hashes. This matching process is powered by a cryptographic technology called private set intersection, which determines if there is a match without revealing the result. The device creates a cryptographic safety voucher that encodes the match result along with additional encrypted data about the image. This voucher is uploaded to iCloud Photos along with the image.

计划将扫描功能作为iOS 15的一部分推出，但这是OS的另一部分，尚未准备好发布。该公司已经宣布，iCloud Private Relay和SharePlay不会为iOS 15的发布做好准备。其CSAM扫描仪现在加入了移动操作系统的延迟部分列表。
