Description

Method for starting application of smart device and starting device

Technical field

The present invention relates to the field of smart devices, and in particular, to a method and a boot device for an application for a smart device.

Background technique

With the development of Internet technology and the popularity of smart devices, users are increasingly demanding information security, and identity recognition applications are becoming more widespread. When the smart device is unlocked, the user sets the unlock password in advance. When the smart device is in the lock screen state, the smart device unlocks only when the current user enters the correct unlock password.

With the development of fingerprint recognition technology, fingerprint recognition buttons have been widely used in access control, car startup, sign-in, banking and so on. The advantage of using fingerprint recognition is that it eliminates the possibility that important passwords may be leaked, increases the security of users, and is convenient to carry, and avoids the possibility that the user may forget the password.

Not only that, but for applications that require a high level of security, the user can also pre-set the password used to launch the application. When the user wants to launch the application, click the icon of the application, the smart device detects the user's click operation on the application icon, displays a password verification interface, obtains the password input by the user on the password verification interface, and determines the user. The entered password matches the preset password. If the password entered by the user matches the preset password, the verification passes and the smart device launches the application.

In addition, with the development of smart devices, such as personal digital assistants (PDAs), smart phones, and Internet technologies, smart devices equipped with fingerprint recognition buttons have emerged, but the smart devices use fingerprint recognition buttons. It is relatively simple, and is usually used to replace the password input when the smart device is started, or to authenticate the user instead of password authentication when the smart device performs mobile payment for e-commerce or mobile financial operation. But this is just a replacement for user password input, the application side is still too singular, and because of the proliferation of mobile viruses and security reasons, not all users are accustomed to mobile payments on mobile phones, which further An application that limits smart devices with fingerprint recognition buttons.
