作法：封锁智慧型手机上的成人内容
色情是印刷品或視覺材料，其中包含對生殖器或性活動的明確描述或演示；這些材料旨在刺激色情，而不是審美感覺或情感。
問題在於色情在網際網路上無處不在，因此很難完全避免色情。但是，大多數父母想知道他們可以採取哪些措施來防止孩子在使用數字設備時看到成人內容。

安全的Google搜索
將Google設置為默認搜尋引擎。
檢查孩子使用的所有瀏覽器（Chrome，Safari，Internet Explorer，Firefox等），並確保將Google用作默認瀏覽器。在iPhone上，轉到手機的設置，向下滾動並單擊Safari，然後在「搜尋引擎」部分中選擇Google。
開啟安全搜索
在行動裝置上，打開Google應用（如有必要，請下載）。點擊齒輪圖標，向下滾動並單擊「搜索設置」按鈕，然後在「安全搜索過濾器」部分中單擊「過濾器顯式結果」。在台式機和筆記本電腦上，訪問www.google.com並單擊右下角的「設置」按鈕；單擊「搜索設置」，然後單擊「打開安全搜索」，然後單擊「鎖定安全搜索」。
定期檢查所有設備
對孩子使用的所有設備執行第一和第二步。定期檢查您的Google應用和設置部分，以確保未禁用安全搜索。
重要說明
免費使用Google SafeSearch，但並非沒有錯誤。安全搜索僅過濾搜索結果-如果直接在瀏覽器中輸入URL，則不會阻止訪問色情網站。
使用安全的DNS服務阻止成人內容
域名系統（DNS）的工作方式
可以將DNS與Internet上的數字電話簿進行比較。人們通過在瀏覽器的地址欄中輸入網站域名來訪問網站，例如「 example.com」（也稱為「主機名」），而計算機使用IP位址（許多數字）進行通信，例如127.0.0.1。 DNS將域名轉換為IP位址，以便您的計算機可以轉到該地址並請求信息。 DNS伺服器遍布世界各地，並擁有公共IP位址和與其關聯的主機名的資料庫。
DNS阻止的工作方式
從此信息中可以很明顯地看出，您可以使用DNS伺服器對IP位址進行分類和過濾，以限制對某些類別站點的訪問。這意味著，如果您指示設備使用特定的DNS伺服器，該伺服器的資料庫不包含某些站點的地址，則將無法從該特定設備訪問這些站點。
如何使用DNS阻止訪問色情內容
任何設備都使用DNS連接到Internet。負責DNS的設置名稱可能會有所不同，具體取決於設備，作業系統的版本，語言等。因此，在設備上可能找不到與以下示例完全匹配的項目。不過，不要著急：您只需打開設備的「設置」，然後查找「網絡設置」或「 Wi-Fi設置」，其中應包含允許您將DNS伺服器（也稱為NameServers）更改為IP位址的項目，由安全DNS服務提供。
讓我們看一個使用免費的CleanBrowsing服務的示例：
對於Mac和Linux計算機：轉到設置->網絡-> Wi-fi->高級，然後將DNS伺服器更改為IP位址185.228.168.168
對於ChromeBook：轉到設置->網絡-> Wifi並配置自定義NameServer，並在其中指定以下IP位址：185.228.168.168和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.
