Description

Information processing apparatus, information processing method and program {INFORMATION PROCESSOR, INFORMATION PROCESSING METHOD, AND PROGRAM}

TECHNICAL FIELD The present invention relates to an information processing apparatus, an information processing method and a program, and more particularly, to an information processing apparatus, an information processing method and a program for locking / unlocking an information processing apparatus with a simple operation.

Recent information processing apparatuses are configured to prevent unauthorized access to the apparatus by persons other than a predetermined user from the viewpoint of security. For example, for security purposes, a screen protector with a password protection is set in advance for the information processing device, and when the predetermined user is once separated from the information processing device, the information processing device is locked immediately so that the user is separated from the device. In the meantime, the device is configured such that no one can use the device. Generally, in order to lock the information processing apparatus provided with a computer, the shortcut key which combined several predetermined keys, for example, [Windows (trademark)] + [L] key is operated. .

In addition, for security, predetermined user authentication (password authentication, biometric authentication, etc.) is required after the user returns and before the user is allowed to access the information processing apparatus. In this case, in order to put the information processing device in the unlocked state from the locked state, the [CTRL] + [ALT] + [DEL] keys are operated, and then authentication operations such as password authentication and biometric authentication are performed.

However, simultaneous operation of a plurality of keys, such as the [Windows (registered trademark)] + [L] key and the [CTRL] + [ALT] + [DEL] keys, is complicated and the [CTRL] + [ALT] + [DEL] keys. Simultaneous operation of three or more keys, etc., depends on the type of keyboard, but cannot be operated with one hand, so that user operation for security is not easy.

The invention described in Patent Literature 1 provides an information processing apparatus (system with a computer) and a method for enabling the system to be locked with one button in order to simplify user operation for security. According to the invention described in Patent Literature 1, a key pressing operation for starting a screen saver for realizing locking of a system by receiving hardware that detects a pressing operation of a security button and notifies the BIOS, and a notification that a pressing operation of the security button has been performed. And a BIOS that issues the same event as the event that is issued when there is a resident program, and an API under the control of 0S which requests the startup of a screen saver that locks the system in response to an event issued by the BIOS. In response to a request from a resident program, the screen saver is activated to lock the system.
