| 20150301919 | PROTECTION METHOD FOR DATA INFORMATION ABOUT ELECTRONIC DEVICE AND PROTECTION CIRCUIT THEREFOR - Disclosed is a method for protecting data information of an electronic device, comprising the following steps: 1) performing power-on detection on an electronic device of which production and installation are completed, detecting the stray capacitance of a signal line thereof, and recording same as a standard value of the signal line; 2) during a power-on operation, monitoring the stray capacitance of the signal line; 3) comparing the monitored capacitance value with the standard value, and entering step 4) when exceeding the set threshold value, otherwise entering step 2); and 4) erasing significant data in the electronic device. The method uses the manner of monitoring the stray capacitance to monitor the contact of outside foreign matter with the signal line, guarantees the security of data in the electronic device, and has the characteristics that the implementation process is simple and easy, safe and reliable, and the cost is low. | 10-22-2015 |
| 20130232020 | METHOD FOR PREVENTING ILLEGAL RELOCATION AND COMMUNICATION RETRANSMISSION AND DEVICE THEREOF - A method for preventing illegal relocation and communication retransmission includes a fixed terminal arranged in an electronic equipment service area and a movable terminal arranged in the electronic equipment. The movable terminal accesses to and is registered with the fixed terminal to be bound with the same, in-place confirming communication is carried out between the movable and fixed terminals regularly or irregularly, the fixed terminal judges whether the movable terminal is located in a limited service area according to the communication transmission time, the movable terminal is not located in the limited service area and stops working and/or sends an alarm if the difference between the communication transmission time and the preset time value is larger than the set range and contrarily works normally. The defect that service areas of terminals of the electronic equipment cannot be limited in the prior art is effectively overcome by the present invention. | 09-05-2013 |
| 20130222320 | SAFETY PROTECTION METHOD AND DEVICE OF ELECTRONIC DEVICE TOUCH SCREEN - The present invention discloses a safety protection device of an electronic device touch screen including a detection module, a control processing module and a self-destroying/alarming execution module, wherein the detection module is used for applying excitation signals on an electrical pin of the touch screen and detecting corresponding electrical characteristic value to serve as characteristic information, and the control processing module is used for receiving the characteristic information and judging whether the characteristic information is in consistency with prestored standard characteristic information, controlling normal working of the electronic device if the result of judgment is yes and controlling the electronic device to stop working and enabling the self-destroying/alarming execution module to carry out actions of self information destroying/alarming transmission if not. The device of the present invention can greatly improve safety performance of electronic device. Simultaneously, the present invention provides a corresponding safety protection method. | 08-29-2013 |
| 20130214047 | IC CARD READER AND IC CARD SEAT PROTECTOR THEREOF - An IC card seat protector includes a plastic part including a first and second side arms and a connecting arm connecting therebetween, a flexible printed circuit at least covering the top, bottom and outer lateral faces of the plastic part, a first and second conductive strips; the first side arm has a first through hole formed on one end thereof and the second side arm has a second through hole formed on one end thereof; the first conductive strip is inserted into the first through hole and one end thereof connects to the flexible printed circuit while the other end thereof is exposed on the bottom face of the first side arm; and the second conductive strip is inserted into the second through hole and one end thereof connects to the flexible printed circuit while the other end thereof is exposed on the top face of the second side arm. | 08-22-2013 |
