Method and device for adjusting target hitting characteristics according to attacking logs

The invention relates to a method and device for adjusting target hitting characteristics according to attacking logs. An IP address of a terminal can hit the plurality of target hitting characteristics in a certain period of time when the terminal attacks a protected web server, and each target hitting characteristic corresponds to a small number of attacking logs. Therefore, the target hitting characteristics and target websites of all attacking logs in the same IP address in the first time interval are the same, and when the number of all the attacked logs in the first time interval is larger than or equal to a first preset threshold, it is considered that a false alarm is given when the IP address browses the target website, the IP address and the target website are simultaneously avoided in the target hitting characteristics, and therefore the terminal with the IP address is not intercepted when the terminal browses the target website and is matched with the target hitting characteristics, terminals with other IP addresses are intercepted when the terminals browse the target website and are matched with the target hitting characteristics, and the attacking logs are generated. False alarms are reduced without directly abolishing a certain rule and on the premise of not reducing the defending effect.

Novel improved immunochromatographic test strip, and preparation and application thereof

ActiveCN105486859AHigh sensitivityReduce false positivesBiological testingColloidal particleImmunochromatographic test
The invention provides a novel improved immunochromatographic test strip, and preparation and application thereof. According to the invention, a buffer pad is additionally arranged between a reaction membrane and a colloidal particle conjugate releasing pad with a marked antibody against a to-be-detected object, so colloidal particles of the antibody against the to-be-detected object disintegrated from the releasing pad can be more uniformly dissolved in a detection sample in the buffer pad before falling onto the reaction membrane, adequate reaction time is obtained, and a corresponding target detection object undergoes more complete immunoreaction; thus, the reaction efficiency of the antibody against the to-be-detected object and the target detection object in the sample is maximized. Compared with conventional immunity immunochromatographic test strips, the novel improved immunochromatographic test strip in the invention has the advantages of high sensitivity, low false positive diagnosis rate, uniform color of a test line; and a preparation method for the novel improved immunochromatographic test strip low in cost, simple to operate and applicable to preparation of immunochromatographic test strips of a variety of forms.

Rule based interactive Chinese spam filtering method

The invention relates to a rule based interactive Chinese spam filtering method. The method comprises a first step of extracting a Chinese spam filtering rule from Chinese spam samples; a second step of training by use of an improved genetic algorithm to obtain an optimum weight distribution of the rule; a third step of intensifying interaction between a user and a server, collecting and analyzing false negative and false positive information that are fed back by the user; and a fourth step of regulating the weight of a sensitive rule in time through an incremental learning method. In the method, the rule weight distribution is trained by use of the improved genetic algorithm, the false negative and false positive information is collected through interaction between the user and the server, and the rule weight is corrected by use of the incremental learning method according to an analysis result, so that false positive rate and false negative rate are lowered, and the filtering adaptivity is improved. The interactive filtering method reduces misjudgement and has a better filtering effect while guaranteeing that identification rate of spam is not lowered. The incremental learning method lowers the retraining frequency, makes weight updating faster, and improves the overall performance of a filtering system.

Driving behavior sensing method based on information fusion and system thereof

The invention discloses a driving behavior sensing method based on information fusion and system thereof. The method includes the following steps of collecting acceleration, vehicle speed and course angle of a vehicle by means of a sensor assembly integrated on the vehicle; according to the acceleration, the vehicle speed and the course angle, conducting horizontal alignment and course alignment on a vehicle coordinate system and detecting the alignment results; according to the acceleration, the vehicle speed and the course angle, judging whether or not behaviors such as speed increase, speedreduction, steering and collision happen to the vehicle, and recording and uploading related data if yes. The acceleration, the vehicle speed, the course angle and other different kinds of vehicle data of the vehicle are obtained through an acceleration meter (namely a gyroscope or a compass), a GPS module and the like. The acceleration, angular velocity, a magnetic direction and other multidimensional data such as the course angle, the height and the vehicle speed in a GPS can be utilized for fusion analysis, the probability of misdetection and measurement omissions is substantially decreased, and complete data during occurrence of an event can be accurately recorded to provide bases for further analysis.

Operation state monitoring method of railway through line cable

The invention provides an operation state monitoring method of a railway through line cable and belongs to the field of on-line monitoring of the railway through line cable. The operation state monitoring method comprises a high-speed railway through line cable and is characterized in that by detecting a bus PT zero-sequence voltage transient-state signal of the railway through line cable is generated or not, whether an instantaneity transient-stat fault occurs to the high-speed railway through line cable is judged; and by monitoring and recording electromagnetic transient-state signal which is generated by the high-speed railway through line cable and flows through a metal shielding layer, fault early warning is performed on the high-speed railway through line cable and the fault point distance is indicated. Compared with the original cable operation state monitoring method, the operation state monitoring method provided by the invention is advantageous in that early warning can be given to an instantaneity transient-stat grounding fault before a cable is damaged; non-fault disturbance signals generated by passing of a train, reclosing and the like can be filtered; system misinformation caused by disturbance is effectively reduced; alarm accuracy is improved; and false alarm rate is reduced.
