The invention provides a task approval method and system of a data leakage prevention system. The method comprises steps that document content of a task approval request is acquired; candidate sensitive keywords of the document content are extracted according preset rules; a target sensitiveness level of the document content is calculated according to the preset corresponding relationship betweensensitive keywords and weight and the candidate sensitive keywords; a target sensitiveness level interval corresponding to the target sensitiveness level and the target approval result corresponding to the target sensitiveness level interval are searched according to the preset corresponding relationship between the sensitiveness level interval and the approval result; a task approval request is responded, and the target approval result is returned. The method is advantaged in that automatic approval of the task approval flow is realized, approval efficiency is improved, moreover, a key information leakage problem caused by manual operation is voided, and safety of the important information is guaranteed.

The invention discloses a chip-based side channel leakage analysis system and method. The system comprises a chip carrier, a probe seat, a probe, an information acquisition module and a workstation. The chip carrier is used for carrying a chip to be tested, the probe seat is used for carrying the probe, and the probe is used for obtaining information leakage of a target trace inside the chip to betested. The information acquisition module is connected with the probe and used for acquiring information leakage obtained by the probe. The workstation is connected with the information acquisitionmodule and used for processing and analyzing the information leakage acquired by the information acquisition module. The side channel leakage analysis system and method introduce the probe, and directly obtain the information leakage of the target trace inside the chip through the probe. Thus, the accuracy of an attack and the signal-to-noise ratio of the obtained curve can be improved, and certain security measures can be selectively bypassed to achieve a more comprehensive security assessment with practical operability.

The embodiment of the invention discloses a freezing method of an application program. The freezing method is used for freezing background operating programs which do not accord with security specifications. The method provided by the embodiment of the invention comprises: acquiring current behavior data of each operating program in the background operating programs; determining target operating programs with the behavior data which does not accord with pre-set security conditions from the background operating programs; freezing the target operating programs. The embodiment of the invention further provides a terminal, and the terminal can be used for freezing the background operation programs which do not accord with the security specifications, so that a phenomenon that illegal behaviors including privacy information leakage and the like, which are not good for users, is prevented from occurring.

The invention provides a car movement device with information leakage prevention. The device comprises a dimensional code information note, a car owner sending end, a car movement request sending end, a server, a car owner receiving end, a GPS positioning chip, a wireless network and a mobile terminal. The dimensional code information note is arranged at the front end face of the owner car and is internally provided with the GPS positioning chip. The car owner sending end is connected to the car movement request sending end through the dimensional code information note. According to the car movement device, through the cooperation of the dimensional code information note, the car movement request sending end, the server and the car owner receiving end, when the device is used, the dimensional code information note with car owner information is pasted to a car, when other cars are stopped by the car, the owner of the stopped card can scan the dimensional code information note by using the car movement request sending end in a hand, enter into the server and send the car movement request information to the car owner, the car owner receives the car movement request information and can move the car as soon as possible, and the device is very convenient.

Embodiments of the invention disclose a method for managing an account, used to prevent information leakage caused by leaving the equipment after the user logs in, thereby improving the security of the account information. The method provided by the embodiments of the invention comprises the following steps: when the target equipment has an input operation within a preset duration, acquiring biometric information of the target user by using the target equipment, wherein the target equipment is equipment that has logged in the target account; determining whether the biometric information of thetarget user matches the biometric information of the registered user corresponding to the target account; and if not, sending prompt information. The embodiments of the invention also disclose a device for managing an account, which is used to prevent information leakage caused by leaving the equipment after the user logs in, thereby improving the security of the account information.

The invention discloses a computer information leakage prevention device and a use method. The computer information leakage prevention device comprises a base and a computer screen mounted at the topof the base, a partition plate is arranged on one side of the computer screen; a mounting groove matched with the partition plate is formed in one side of the top of the base; the bottom of the partition plate extends into the mounting groove and is movably connected with the mounting groove; a threaded groove is formed in one side of the top of the base, a screw is installed in the threaded groove in a threaded mode and located on the side, away from the computer screen, of the partition plate, the same rectangular groove is formed in the inner wall of the bottom side of the installation groove and the inner wall of the bottom side of the threaded groove, and a first groove is formed in the bottom of the side, away from the screw, of the partition plate. The computer information leakage prevention device is reasonable in design, effectively prevents a peeper from peeping contents on the computer screen, can give an alarm to remind a user when the peeper disassembles the partition plate, and effectively guarantees the information safety on the computer screen.

The invention discloses a cheating-based node hiding method, system and device for the Internet. The method comprises the following steps: replying a customized data packet containing spoofing information to a visitor through a constructed camouflage protocol stack when the target device receives a detection/scanning request from the external visitor, wherein the data packet replies to the visitor through equipment fingerprint information different from the target equipment, and the service type of the data packet is the same as the service type of the detection/scanning request of the visitor; enabling the target device to analyze the content of detection/scanning and the response content of the visitor to the data packet, and extracting the detection skill and evidence chain of the visitor to gradually enrich the detection capability of the camouflage protocol stack. The constructed camouflage protocol stack is used for replacing the protocol stack of the target equipment to reply the data packet to the visitor, so that the real information (fingerprint) of the target equipment is hidden, the target equipment is prevented from being attacked due to information leakage, and the security of the target equipment is improved.
