How to:Block adult content on smartphone/zh

色情是印刷品或视觉材料，其中包含对生殖器或性活动的明确描述或演示；这些材料旨在刺激色情，而不是审美感觉或情感。

问题在于色情在互联网上无处不在，因此很难完全避免色情。但是，大多数父母想知道他们可以采取哪些措施来防止孩子在使用数字设备时看到成人内容。

安全的Google搜索

将Google设置为默认搜索引擎。

检查孩子使用的所有浏览器（Chrome，Safari，Internet Explorer，Firefox等），并确保将Google用作默认浏览器。在iPhone上，转到手机的设置，向下滚动并单击Safari，然后在“搜索引擎”部分中选择Google。

开启安全搜索

在移动设备上，打开Goog​​le应用（如有必要，请下载）。点击齿轮图标，向下滚动并单击“搜索设置”按钮，然后在“安全搜索过滤器”部分中单击“过滤器显式结果”。在台式机和笔记本电脑上，访问www.google.com并单击右下角的“设置”按钮；单击“搜索设置”，然后单击“打开安全搜索”，然后单击“锁定安全搜索”。

定期检查所有设备

对孩子使用的所有设备执行第一和第二步。定期检查您的Google应用和设置部分，以确保未禁用安全搜索。

重要说明

免费使用Google SafeSearch，但并非没有错误。安全搜索仅过滤搜索结果-如果直接在浏览器中输入URL，则不会阻止访问色情网站。

使用安全的DNS服务阻止成人内容

域名系统（DNS）的工作方式

可以将DNS与Internet上的数字电话簿进行比较。人们通过在浏览器的地址栏中输入网站域名来访问网站，例如“ example.com”（也称为“主机名”），而计算机使用IP地址（许多数字）进行通信，例如127.0.0.1。 DNS将域名转换为IP地址，以便您的计算机可以转到该地址并请求信息。 DNS服务器遍布世界各地，并拥有公共IP地址和与其关联的主机名的数据库。

DNS阻止的工作方式

从此信息中可以很明显地看出，您可以使用DNS服务器对IP地址进行分类和过滤，以限制对某些类别站点的访问。这意味着，如果您指示设备使用特定的DNS服务器，该服务器的数据库不包含某些站点的地址，则将无法从该特定设备访问这些站点。

如何使用DNS阻止访问色情内容

任何设备都使用DNS连接到Internet。负责DNS的设置名称可能会有所不同，具体取决于设备，操作系统的版本，语言等。因此，在设备上可能找不到与以下示例完全匹配的项目。不过，不要着急：您只需打开设备的“设置”，然后查找“网络设置”或“ Wi-Fi设置”，其中应包含允许您将DNS服务器（也称为NameServers）更改为IP地址的项目，由安全DNS服务提供。

Let's look at an example, where the free CleanBrowsing service is used:

For Mac and Linux computers: go to Settings-> Network-> Wi-fi-> Advanced and change the DNS servers to IP address 185.228.168.168

For ChromeBook: go to Settings-> Network-> Wifi and configure custom NameServers, stating the following IP addresses there: 185.228.168.168 and 185.228.169.168

For Windows 10: click Start -> Settings -> Network & Internet -> Ethernet or Wi-Fi (depending on your connection) -> select the network connection-> under the "IP settings" section, click the Edit button, from the drop-down menu select Manual option, turn on the IPv4 toggle switch and type 185.228.168.168 and 185.228.169.168 into the "Preferred DNS" and "Alternate DNS" fields.

For iPhone, Android, and iPad: go to Settings -> Wi-Fi Settings and configure Name Server by specifying the IP address 185.228.168.168 in it.

For your home router and complete home protection: Log in to your router, find "Settings" or "DNS Settings" and change the Nameserver, specifying the IP address 185.228.168.168 in it.

If possible, configure DNS on your home router, so that all devices in your home will be protected. This applies to Internet-connected TVs, game consoles (xBox, Playstation, Nintendo Wii), computers or mobile devices.

Block adult content using built-in protection in iOS and Android

How to block porn content on iOS devices

Use the Screen Time app on iPhone and iPad

First you should decide how exactly you want to use the blocking feature: you can set restrictions directly on your child's device by applying password protection, or you can control the device remotely using "Family Sharing" function.

How to block access to insecure content on an iOS device

Open settings on your child's device. Scroll down and tap "Screen time." Select "Content & Privacy Restrictions" and enable this feature. Review all the settings and determine what you want to allow and what to restrict. To block access to porn, go to "Content Restrictions" section and disable all explicit content for everything, including web content.

Protecting the settings with a password.

In "Settings/Screen Time" menu, click "Use Screen Time Passcode". Enter a four-digit code that your child does not know and which he cannot guess.

Setting up remote control for your iOS device using Family Sharing feature

Open "Settings", click on the name of your account, scroll down and click on "Family Sharing". Follow the instructions to add a new family member. After all the items are configured, you will be able to control all the functions of "Screen Time" on this d iOS device, including all restrictions on content and privacy, from your phone.

How to block porn content on Android

Use Google Family Link app

Make sure your device is compatible with Family Link. (https://families.google.com/familylink/device-compatibility/).

Do download the Family Link app to your Android device from Google Play Store. Do the same on the Android device, from which you want to control your child's device. Next, follow the instructions to configure the application on both devices. After that, you can change your child's Android device settings remotely.

Attention! The Google Family Link application itself does not block anything, but it allows you to control the child's device from your device. For example, you can set up a secure Google search, blocking unwanted content via DNS or using specialized software with parental controls.

Use special applications for parental control

For Android operating system, there is a large number of applications with parental control functions, so you can choose the one, which meets your needs. We recommend that you take a look at Hoverwatch - here is a detailed review of Hoverwatch app.
