The disclosure relates to privacy protection of handheld devices. And more particularly, to lock the screen to protect privacy of handheld device when handing to others. As the development of period, handheld devices like cell phones, pads, are more and more popular. Meanwhile, privacy protection on these devices becomes an important issue. There always is a situation that people hand his phone to others to show something, like baby’s picture, a joke, interesting news, etc. Once the phone is on other’s hands, people can easily play with the phone. They can check messages, mails, pictures on it, which is absolutely not expected to happen. So how to avoid this, it is worth to think. Currently, the most common way to do this is encryption. With encryption, application access is only allowed when providing correct password. Encryption can solve the problem well if all the applications are encrypted, but it brings other problem. That is, since all the applications are encrypted, every time even the user himself has to provide password to access the application, which is too inconvenient. So to achieve privacy protection, a new mode called read-only mode for handheld devices is proposed here.

Privacy protection of handheld devices with Read-only mode

For example, when you want to show a picture in your cell phone to others, first find and open the picture, then open read-only mode, so when other people get your phone, he can only see what is present on the screen, but can not do anything else. With this function, others can not operate the phone, so it can effectively protect privacy. Compared with encryption, read-only mode is much more convenient. Read-only mode is easy to implement. It contains three parts: lock, unlock, password. User can choose if open this function or not. And if it is opened, the user will be asked to set a password, which is used to unlock the screen. There are several ways to implement this function, adding a special button on somewhere of the device, once the user want to lock the screen, what he has to do is to press the button. Press the button again and enter corresponding password can unlock the screen. Or much simpler, adding a “Lock” option on the screen. Once this option is clicked, “Lock” changes to “Unlock” and screen is locked, device enters read-only mode. Click “Unlock”, and provide correct password, device is back to normal mode. Here password can also be replaced with fingerprint if the device support fingerprint. Figure 1 shows how to use t...
