iOS 26升级为Safari浏览器带来更强隐私防护，默认开启“高级跟踪与指纹保护”功能

在日常网络冲浪中，用户是否曾感觉广告总能精准投其所好？这背后往往是网站跟踪器通过收集设备信息构建用户“数字指纹”进行追踪的结果。近日，随着iOS 26等苹果操作系统更新，一项名为“高级跟踪与指纹保护”的功能得到重要升级，现已默认在Safari浏览器中为所有浏览模式开启，为用户构建更坚实的隐私防线。

所谓“数字指纹”，是指跟踪器通过获取用户设备的IP地址、浏览器类型、屏幕分辨率、安装字体等细微数据，组合成可唯一识别用户的个人画像。此前，该保护功能仅默认在“无痕浏览”模式下生效，若用户未主动在设置中调整，常规浏览时仍会暴露于跟踪风险中。

本次更新后，无论用户使用普通窗口还是无痕窗口，该功能均会自动启用，通过简化向网站发送的设备数据，降低用户指纹的独特性，使跨网站跟踪行为难以实现。这一设置同时适用于升级至最新版本的iPadOS和macOS。

用户可进入“设置”>“Safari浏览器”>“高级”选项，确认功能已设置为“所有浏览”以全面启用保护。专家指出，此次默认设置升级将有效提升大众用户的隐私安全水平，减少个人数据被用于精准广告投送或转售的风险。

您知道吗？只需简单设置，就能让谷歌自动过滤垃圾信息，从而优化搜索结果——比如将Lifehacker网站添加为优先信源。

网络世界虽无绝对隐私，但这不意味着您需要主动公开所有信息。默认情况下，您在浏览网页时追踪器会窃取大量数据，但通过简单设置就能阻断多数追踪器。事实上，将iPhone升级至iOS 26系统后，设备会新增一项强化反追踪工具。

这项名为"高级追踪与指纹防护"的功能内置于Safari浏览器，可隐藏追踪器常用于构建用户数字"指纹"的浏览器与设备数据。数字指纹是企业用来追踪您网络行为的画像，可能包含设备IP地址、硬件型号、浏览器类型、字体、插件及屏幕分辨率等数据。这些信息共同构成独特的身份画像——指纹越独特，被追踪的风险越高，因为找到完全重复数据的可能性微乎其微。

指纹技术在网络应用广泛，最主要体现在精准广告推送。您看到的广告之所以高度契合个人兴趣与浏览记录，正是基于指纹追踪。追踪器掌握您的网络习惯后，便能精准投送最可能点击的广告。企业还可将这些指纹画像转售给中介和广告商，从您的广告互动及原始数据中双重获利。

高级追踪与指纹防护功能会简化每位Safari用户的数据特征，降低指纹独特性，使追踪器难以识别个体身份，从而实现更私密的网络浏览。

其实iOS 26之前iPhone就已具备此功能，但默认仅限无痕浏览模式生效。除非手动调整为全浏览模式，否则普通标签页会失去这部分隐私保护（iPadOS和macOS系统同理）。由于该设置深藏于系统菜单，多数用户未必进行过调整。

而升级至最新系统后，所有浏览模式都将默认启用增强追踪防护。无论使用无痕窗口还是普通窗口，追踪器都更难识别您的设备。

如何检查高级追踪与指纹防护设置
设备更新后此功能应默认开启，若需确认状态：

• iPhone/iPad：前往"设置 > Safari浏览器 > 高级"
• Mac：打开Safari，按Command+，进入设置后选择"高级"标签页
  请确保选项设为"所有浏览"（iOS/iPadOS）或"在所有浏览器中"（macOS）。

The internet isn't private, but that doesn't mean you have to willingly give up all of your information to use it. By default, trackers steal a lot of your data while you browse the web, but simple settings can block a lot of those trackers from functioning. As it turns out, by updating to iOS 26, your iPhone gets an upgraded tool against tracking.
The feature, called Advanced Tracking and Fingerprinting Protection, is an option in Safari that hides certain browser and device data trackers typically use to build a digital "fingerprint" of users. In this case, a fingerprint is a profile companies use to track your movements across the web. Your fingerprint may be made up of data like your device's IP address, the device itself, your browser, fonts, plug-ins, as well as its screen resolution. All of these data points come together to build a unique picture of who you are; the more unique your fingerprint, the easier it is to track you, since the odds of someone else with your exact same details is slim.
Fingerprinting has a number of applications across the web, but perhaps the largest is for targeted advertising. The reason many of the ads you see are so relevant to your interests and browsing history is because of fingerprinting. Trackers know your internet habits, and can identify and deliver the advertisements you're most likely to click or tap on. Companies can also sell these fingerprinting profiles to brokers and advertisers, making money on both your engagement with ads, as well as your raw data.
Advanced Tracking and Fingerprinting Protection simplifies each Safari user's data, so our fingerprints aren't quite so unique. By doing so, it's harder for trackers to identify individuals, and, as such, makes it possible to browser the web more privately.
This feature was already a thing on iPhone before iOS 26. However, it was limited to Private Browsing by default. If you didn't do all your browsing in a private tab, you likely lost some of these privacy protections, unless you knew to manually change the setting to cover all browsing. The same goes for iPadOS and macOS as well. Most of us probably didn't change the setting, since it's quite buried in each OS' respective settings.
Once you update your iPhone, iPad, or Mac to the latest OS, however, your browsing gets these added tracking protections by default. Whether you browse in a private or a normal window, trackers will have a difficult time identifying your device.
How to check your Advanced Tracking and Fingerprinting Protection settings
This setting should be enabled by default when you update your device. But if you want to make sure it's on, here's where to find it. On your iPhone or iPad, open Settings, then head to Apps > Safari > Advanced. On your Mac, open Safari, press Command + , to pull up Safari's settings, then choose the Advanced tab.
From here, ensure Advanced Tracking and Fingerprinting Protection is set to "All Browsing" (iOS/iPadOS) or "in all browsing" (macOS).
