Embodiment Construction

[0011] Such as figure 1 Shown is a block diagram of the electronic device 1 with anti-theft function of the present invention. The electronic device 1 includes a plurality of touch sensing units 11 , a storage unit 12 , an alarm unit 13 and a processing unit 14 . The multiple touch sensing units 11 cover the surface of the electronic device 1 , and can generate sensing signals when touched by the user, and transmit the generated sensing signals to the processing unit 14 for processing. The storage unit 12 stores at least one preset graphic. Generally, when a thief steals the electronic device 1, the gestures used by the user to take the electronic device 1 will be different. For example, when the thief steals the electronic device 1, he generally adopts the method of holding the electronic device 1 with his hand, so his hand is in contact with the surface of the electronic device 1. The pattern formed after contact is generally an approximate straight line or a point formed ...

Abstract

The invention provides an anti-theft method applied to an electronic device. The surface of the electronic device is covered with a plurality of touch-sensitive units, and at least one default image is stored in the electronic device. The method comprises the following steps of: receiving touch-sensitive signals transmitted by the touch-sensitive units; determining the positions of the touch-sensitive units for generating each touch-sensitive signal on the surface of the electronic device, and generating a touch image according to the determined position of each touch-sensitive unit on the surface of the electronic device; comparing the generated touch image with the default image in a storage unit, and judging whether the similarity between the generated touch image and the default image is larger than a default value; and when the similarity between the generated touch image and the default image in the storage unit is larger than the default value, sending out an alarm command to an alarm unit, and controlling the alarm unit to give an alarm. Meanwhile, the invention provides an electronic device using the anti-theft method. According to the method when the electronic device is stolen, a user can be prompted, and therefore the electronic device is prevented from being stolen.

Description

technical field [0001] The invention relates to an electronic device and method with anti-theft function. Background technique [0002] Now hand-held electronic devices are light, thin, short, and small, and users can carry them with them so that they can be used at any time. But also because of the lightness, thinness, shortness, and smallness of the portable electronic device, it gives the thief an opportunity to steal it without the owner noticing and guarding against it. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device and method with anti-theft function, which can alarm and prompt the user when the device is stolen. [0004] The electronic device with anti-theft function includes a storage unit storing at least one preset pattern; a plurality of touch sensing units covering the surface of the electronic device for sensing user's touch and generating sensing signals; A sensing signal receiving module, receiving the t...
