Problems solved by technology

[0003] However, the password in the form of numbers or characters requires the user to look further at the typed characters or numbers displayed on the screen of the electronic device to repeatedly confirm whether they are correct, which is very troublesome for elderly users with poor eyesight
In addition, if a fingerprint reader is used to achieve the security effect, because the price of the fingerprint reader is not low, the cost of the electronic device will increase.

Embodiment Construction

[0027] Please refer to figure 1 and figure 2 , figure 1 A functional block diagram illustrating an electronic device according to a preferred embodiment of the present invention, figure 2 A timing diagram illustrating the encryption time interval of this embodiment is shown. Such as figure 1 As shown, the electronic device 100 includes a storage unit 102 , a timing unit 104 , an acceleration sensor 106 , a processing unit 108 and a music playing unit 110 . The acceleration sensor 106 is used to detect whether the electronic device 100 is shaken.

[0028] The storage unit 102 stores a password file (not shown) and a music (not shown). The password file is recorded with a music storage path (not shown), a tolerance time Td, M encryption time points and music stop time point Te. Among them, M is a positive integer greater than or equal to 1, such as figure 2 As shown, the value of M in this embodiment is 2 as an example for illustration, that is, the encryption time poi...

Abstract

The invention provides an encryption method and an electronic device using the same. The encryption method comprises the following steps of: firstly, timing and starting an acceleration inductor; judging whether the electronic device is shaken or not at each time in the encryption time interval; then judging whether the electronic device is shaken or not at the time beyond the encryption time interval; if the electronic device is shaken at each time in the encryption time interval and the electronic device is not shaken at the time beyond the encryption time interval, sending a decryption correct signal; and if the electronic device is not shaken at one time in the encryption time interval or the electronic device is shaken at the time beyond the encryption time interval, sending a decryption false signal.

Description

technical field [0001] The present invention relates to a security method and an electronic device using the same, and in particular to a security method with a shaking action and an electronic device using the same. Background technique [0002] Electronic devices can be seen everywhere in today's society, especially portable electronic devices, such as personal digital assistants (Personal digital assistants, PDAs), mobile phones, and notebook computers. Since important information is often stored in electronic devices, some electronic devices will be equipped with a security measure, such as installing a biometric module on the body of the electronic device, such as a fingerprint reader, to achieve the effect of security. Or install a password input program in the system of the electronic device, and require the user to enter a digital or character password at a specific time before entering the operation mode of the electronic device. [0003] However, the password in t...
