As the fingerprint-verifying procedure has to be conducted to unlock the phone before a user may successfully operate the phone, it is troublesome and time-consuming to general users.
Therefore, an object of the present invention is to simplify a user-identifying process of electronic device in order to improve the utilization rate of a user-identifying function for information security of the electronic device.
In an aspect of the present invention, a method of switching a locked state of an electronic device with a user-verifying function is provided. In the method, a biologic feature data from a user is captured while receiving an input from the user for an operation when the electronic device is in a locked state. Whether the biologic feature data conforms to a reference biologic feature data is then determined. If it is determined that the biologic feature data conforms to the reference biologic feature data, the electronic device is switched from the locked state into a non-locked state and directly controls the electronic device to perform the operation according to the input when the biologic feature data is determined conforming to the reference biologic feature data.
In another method of switching a locked state of an electronic device with a user-verifying function according to the present invention, a biologic feature data from a user is captured while receiving an input from the user for an operation when the electronic device is in a non-locked state. Whether the biologic feature data conforms to a reference biologic feature data is then determined. If the biologic feature data is not determined conforming to the reference biologic feature data, the electronic device is switched from the non-locked state into a locked state and prohibited from performing the operation according to the input.
In another aspect of the present invention, an electronic device is provided. The electronic device includes: an input module configured to capture a first biologic feature data from a first user while receiving a first input from the first user for a first operation; a determining module, coupled to the input module, configured to determine whether the first biologic feature data conforms to a reference biologic feature data; and a control module, coupled to the determining module, configured to switch the electronic device from the locked state into a non-locked state, and directly control the electronic device to perform the first operation according to the first input when determining module determines the first biologic feature data conforms to the reference biologic feature data.
In another electronic device according to the present invention, an input module, a determining module and a control module are included, wherein the input module is configured to capture a biologic feature data from a user while receiving an input from the user for an operation of the electronic device when the electronic device is in a non-locked state; the determining module is coupled to the input module and configured to determine whether the biologic feature data conforms to a reference biologic feature data; and the control module is coupled to the determining module and configured to switch the electronic device from the non-locked state into a locked state and prohibit the electronic device from performing the operation according to the input when the determining module determines the biologic feature data does not conform to the reference biologic feature data.
In a further aspect of the present invention, a computer-readable medium having stored thereon instructions is provided. The instructions, when executed by a processor in an electronic device, cause the processor to perform operations of: capturing a biologic feature data from a user while receiving an input from the user for an operation when the electronic device is in a locked state; determining whether the biologic feature data conforms to a reference biologic feature data; and switching the electronic device from the locked state into a non-locked state and directly controlling the electronic device to perform the operation according to the input when the biologic feature data is determined conforming to the reference biologic feature data.
In another computer-readable medium having stored thereon instructions according to the present invention, the instructions, when executed by a processor in an electronic device, cause the processor to perform operations of: capturing a biologic feature data from a user while receiving an input from the user for an operation when the electronic device is in a non-locked state; determining whether the biologic feature data conforms to a reference biologic feature data; and switching the electronic device from the non-locked state into a locked state and prohibiting the electronic device from performing the operation according to the input when the biologic feature data is not determined conforming to the reference biologic feature data.
The above contents of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.

In the embodiment illustrated in
In an example that the electronic device is a mobile phone with a touch screen, a user may conduct a manipulating input by way of the touch screen with his finger even when the mobile phone is in a locked state. While the user's finger is moving on the touch screen to execute a specified function such as scrolling a picture, the user's fingerprint data is captured and compared with the previously stored reference fingerprint data. Alternatively, the user may put his finger on the optical sensor to be scanned so that the mobile phone in the locked state may capture the user's fingerprint data and compare it with the reference fingerprint data. If the two fingerprint data are comparable, the locked state of the mobile phone is cleared so that the picture-scrolling function is performed. On the other hand, if the current user's fingerprint data does not conform to the reference fingerprint data, the mobile phone is still in the locked state. That is, the picture-scrolling function will not be performed.
In another example that the electronic device is a mobile phone with a voice control mechanism, a user may conduct an operation with his voice even when the mobile phone is in a locked state. While the user speaks to execute a specified function such as making a phone call, the user's voice print data is captured by a voice-identifying module and compared with the previously stored reference voice print data. If the two voice print data are comparable, the locked state of the mobile phone is cleared so that the calling function is performed. On the other hand, if the current user's voice print data does not conform to the reference voice print data, the mobile phone is still in the locked state. That is, no phone call could be made.
In this way, an authorized user whose biologic feature data has been registered is capable of using the mobile phone in the locked state without additional operation to unlock the phone. In contrast, an unauthorized user whose biologic feature data was not recorded cannot operate the phone as the phone remains in the locked state. In other words, conventional user-verification conducted through a specific verifying procedure can be exempted from for an authorized user, while information can still be secured from an unauthorized user.

On the other hand, if the current user's fingerprint data does not conform to the reference fingerprint data, the mobile phone enters a locked state. That is, the picture-scrolling function will not be performed.

In the embodiment as shown in
The determining module 31 and the control module 32 can be implemented with microprocessors or digital signal processors. While the user is conducting the input via the input module 30 with his finger, palm, eyeball or voice, the user's biologic feature data is captured at the same time. There is no need for the user to perform any additional user-verifying procedure to acquire the biologic feature data. With the comparison of the captured biologic feature data with the reference biologic feature data, whether the state should be changed or not can be determined. As for the operational details of the modules, they are appreciable from the associated steps described with reference to
