Visiting any website makes us feel like we are being watched, because this is true.
Could you uncover a secret advertising ID on your mobile device that could reveal where you live and even your most recent online shopping list? Even information such as IP address and live address can be tracked easily.
This is just one example of the many spyware, IDs, maps and settings that collect user data. Usually, this sensitive information will be collected and sold to the highest bidder.
|Charging mobile devices in public is quite convenient, but a high risk of personal data security|
To protect their personal information, users will need to do more than usual security steps.
1. Enable limited mode for USB
Have you ever charged your iPhone in public, on an airplane or at work? You will need to enable USB Restricted Mode. This helps prevent hackers from “draining” your device by installing malicious code or stealing information through the USB charging port.
How To: To enable USB Restricted Mode, select Settings > Face ID and Passcode > type your password. Scroll down to “Allow access when locked,” and make sure “USB access” is turned off.
Public charging areas like airports or coffee shops are often convenient, but they can also put your data at risk. If your device runs out of battery while traveling outside, get yourself a power bank and charge it fully before you leave the house. If you need to use a public charger, consider using a USB data blocker to prevent malicious code from entering your device.
2. Automatically delete data
iPhone users should also enable Auto Erase. With this setting enabled, all your data will be erased after 10 incorrect password attempts, thus keeping your information safe if someone tries to gain access to your device.
How to: Select part Settings > Face ID and Passcode > enter your password. At the bottom of the menu, you’ll see the option “Erase all data.”, turn it on.
Warning: If you have “Erase all data” enabled and have children in the house, back up your data regularly. You can easily lose all your data if kids try to open your device more than 10 times.
To make sure iCloud sync is turned on, select Settings > [tên người dùng] > iCloud > iCloud Data Backup. You can also back up manually by selecting Back Up Now.
3. Prevent Snooping
A password to protect your device is essential, but did you know you can set a passcode for individual apps? With an Android device this is quite easy, and a bit more complicated than with an iPhone.
How to do it: With Android devices, third-party software like Smart AppLock allows users to set a fingerprint or passcode or PIN to limit access. Smart AppLock will also send you an alert if someone tries to access it with the incorrect code.
With an iPhone, Guided Access helps you protect your apps. It will take a few steps to install and run this feature. Once done, the Guided Access standby screen will appear, allowing the user to lock a certain part or all of your screen.
4. Delete suspicious apps
All apps on your device now track certain information. The best thing you can do is secure your personal data. You can leave out some unimportant information, or even add incorrect information.
Double check your device to make sure no apps are collecting unnecessary information.
How to do it on iPhone:
– Open Settings, scroll down and select Privacy
– Select the information you want to allow access, for example, Calendar, Location or Camera.
– Choose which applications are allowed to access the above information, and deny access to applications that you do not want to allow access.
On Android devices:
– Open Settings > Apps & notifications, then select Advanced permission settings.
– Select the information and applications that you want to allow access.
– Deny access to suspicious applications.
5. Delete old passwords that have been exposed
For iOS devices, the Keychain password reuse auditing app will use Safari to automatically save old passwords on iCloud. The application will then automatically check which passwords have been exposed. This feature is automatically enabled from iOS 14.
Go to Settings > Passwords and look under “Security Alerts” for any leaked passwords. If so, you will be warned to update the password.
For Android devices, Google Password Checkup is a built-in feature for Password Settings. Here you can check if your passcode has been exposed – and which weak passwords need to be replaced.
