The invention discloses a commodity dynamic information generation method, device and equipment and a computer readable medium, and belongs to the technical field of computers. The method comprises the steps of collecting induction information of a goods shelf and a dynamic image of a customer; screening out an effective dynamic image corresponding to the sensing information from the dynamic images; determining first commodity information corresponding to the sensing information; determining second commodity information corresponding to the commodity in the effective dynamic image; comparing the first commodity information with the second commodity information to obtain a commodity comparison result; comparing the commodity comparison result with an information generation condition, and if the information generation condition is satisfied, generating commodity dynamic information. According to the invention, the second commodity information is obtained by using the effective dynamic image corresponding to the shelf sensing information, the second commodity information is compared with the first commodity information obtained according to the sensing information, and the commodity dynamic information is generated according to the comparison result; therefore, the condition of identification errors caused by the fact that the commodity dynamic information is generated only according to the first commodity information in the prior art is avoided.

The invention discloses a method and a device for behavior verification based on an authentication code, belonging to the technical field of the Internet. The method comprises the following steps: obtaining an authentication code of the terminal, the authentication code being generated by the server and sent to the terminal; obtaining a confirmation instruction for the authentication code, and signing the authentication code based on the private key stored in the designated storage space of the electronic device to generate first signature information; sending the first signature information,an authentication code and a public key index stored in correspondence with the private key to the terminal, so that the terminal sends the acquired information to the server, so that the user does not need to identify the authentication code, only a confirmation instruction to the authentication code needs to be issued to the electronic equipment. As the confirmation instruction requires a manualoperation on the electronic equipment to be triggered, and the machine can not complete the trig process, the server determines that the access behavior of the terminal is a human operation as long as the confirmation instruction is receive, thereby avoiding the identification error of the verification code, improving the verification efficiency and improving the accuracy.

The embodiment of the present invention discloses an information identification method, device and system; this embodiment adopts the method of receiving instant messaging information, and determines whether the sending user belongs to the preset contact set according to the user identification carried in the instant messaging information, and if so, then Extract the content of the instant messaging information, and identify the instant messaging information according to the content; otherwise, if it does not belong to the preset contact set, then identify the instant messaging information according to the user ID; this scheme can greatly improve the blocking effect , Improve information security.

The invention relates to a device for capturing the high beam of a vehicle based on a photoresistor. The device comprises a vertical hollow bracket, in a front side panel of the bracket facing a vehicle approaching direction, a light-shading inner cavity facing the bracket is provided with a high-level light-transmitting hole K1 and a low-level light-transmitting hole K2 in an upwardly inclined manner. A high-level photoresistor Rm1 and a low-level photoresistor Rm2 are correspondingly arranged in the light-shielding inner cavity. The two resistors are connected in parallel and are connected to a trigger circuit of a camera, the trigger circuit is triggered, and the camera is started to take a picture. According to the device, whether a vehicle running in front of a system uses the high beam can be accurately judged, then an image collected by the camera is processed, and whether the front vehicle illegally uses the high beam is judged and evidence is taken. A discovered vehicle whichillegally uses the high beam is captured such that the traffic police can retain the evidence, the behaviors of the illegal use of the high beam of the vehicle and speeding can be warned and suppressed well, and traffic accidents are reduced.

The invention discloses an unmanned convenience store operating system based on body weight verification, and relates to the field of unmanned convenience stores. The present invention includes: a commodity showroom, an entrance weighing device, an exit weighing device, a self-service cash register mechanism and a PC processing module; customers can identify all commodities purchased through the self-service cash register mechanism, and calculate the total price of the commodities purchased by the corresponding customer and the total price of the commodities. weight, and complete the payment; the entrance weighing device collects the initial weight corresponding to the customer entering the entrance, and the exit weighing device collects the terminal weight corresponding to the customer entering the exit. The purpose of the present invention is to overcome the shortcomings of the existing unmanned convenience store in the checkout loss prevention verification process, and provide an unmanned convenience store operation system based on human body weight verification, and the checkout loss prevention verification is efficient and reliable .

The embodiment of the invention relates to the technical field of voice processing and particularly discloses a method, device and system for identifying a target request of a user and a storage medium. The method comprises the steps that a sound signal transmitted by intelligent voice interaction equipment is received; the signal is input to a preestablished sound classifier, a voice identification processing module and an encoder language model separately, and a sound confidence coefficient, a language confidence coefficient and text information are acquired; the text information is input toa text classifier model, and a text confidence coefficient is acquired; the sound confidence coefficient, the language confidence coefficient and the text confidence coefficient are fused, and a confidence coefficient of the target request is acquired; according to the confidence coefficient of the target request, whether or not the sound signal is the target request of the user is determined. Inthis way, unnecessary problems cannot be caused to the user, and the experience degree of the user is greatly improved.

The invention discloses a serial number identification method based on a network message, which solves the problem of low identification accuracy of the serial number through periodical identification and serial number verification methods. According to the principle that the sequence number cycle is monotonic and the phenomenon that multiple message formats share the sequence number, the data after multiple sets are merged is periodically divided and judged to avoid the impact of multiple message formats sharing the sequence number and value drift and loss; It can realize the rapid identification of serial numbers with high accuracy, and verify the identified serial numbers to prevent the impact of numerical drift, multi-serial number mixing, and multi-message format shared serial numbers on the identification of serial numbers. Document classification and state machine inference provide guarantees.
