The present application provides a method for identifying order swiping, which includes: according to the order information of the first type of users in the first set of suspected first type of users who are suspected of swiping orders, determining the second set of second-type users who are suspected of cooperative order swiping; The order information of the second type of users in the second set is extended to the first type of users in the first set; respectively clustering the first set and the second set to obtain the first subset and the second subset ; Determine the first type of users and the second type of users in the first subset and the second subset who cooperate in swiping orders. According to the embodiments of the present disclosure, it is possible to identify a set of users, which is beneficial to improve the identification efficiency, and can also effectively identify complex scenarios of group cooperative order swiping.

The present invention provides a method and device for recognizing a program's billing request that can simply, accurately and efficiently identify a program's billing request in the background. The recognition method for program swiping order includes: a preprocessing step (S1), obtaining the character string requested by the user at the back-end interface, and obtaining a given string processing method; a front-end interface processing step (S2), when there is a When the back-end interface is called, the front-end interface uses the given string processing method to process the string, generates a first string, and writes the first string into the Cookie as check value; back-end interface processing step (S3), using the given string processing method to process the string at the back-end interface to generate a second string, when the second string When it is consistent with the check value read from the cookie, it is determined that the user request is a normal user request; otherwise, it is determined that the user request is a program swiping request.

The invention discloses a method for verifying the authorization code of a terminal decoding library of a POS machine. The method includes firstly, an external tool obtains the unique hardware identification code of the POS machine, encrypts the unique hardware identification code into a 256-byte license file, and The license file is written into the hardware information storage read-only partition. Secondly, when the POS machine is turned on, the system communication module obtains the unique hardware identification code from the hardware information storage read-only partition, and writes the unique hardware identification code into the system hardware identification code registry. And specify the system hardware identification code registry as a read-only attribute, again, the system communication module reads the license file in the hardware information storage read-only partition, writes the license file into the system installation information directory, and writes the system communication module to the system installation information directory The license file below is set to read-only attribute. Finally, start the POS card swiping program, and the card swiping program checks the license file in the system installation information directory and the unique hardware identification code in the system hardware identification code registry.

The invention discloses a watershed segmentation method combined with an improved fast merging algorithm. The method comprises the following steps: step 1) research and develop a set of pre-processing based watershed segmentation algorithm technical process based on GF‑1 data; step 2) research based on the previous In the processed watershed segmentation algorithm, the influence of the global marker threshold α and the regional adaptive threshold adjustment coefficient g on the segmentation results is analyzed, and the value ranges of α and g are analyzed; step 3) based on the initial segmentation results of the pre-processing watershed segmentation algorithm, the RAG and NNG as the implementation method, use the Fast Lambda merging algorithm based on the controllable common boundary length penalty to merge the initial segmentation results to achieve a satisfactory segmentation result; step 4) research the Fast Lambda merging algorithm based on the controllable common boundary length penalty The influence of the threshold value T and the public boundary penalty coefficient λ on the merging result of the control area merging is analyzed, and the value range of T and λ is analyzed.
