The invention embodiment provides an abnormity monitoring method for user registration. The method comprises the following steps: judging if the present registration behavior of a user is abnormal by utilizing history registration information corresponding to an user account according to and responding to a request related to the user account, if yes, storing the abnormal registration information corresponding to the abnormal registration behavior, and generating prompt information by utilizing the stored abnormal registration information and sending the prompt information to the user. The method, provided by the invention, can automatically finish the judgment and prompt of the abnormal user registration behavior according to the history user registration information and the user does not need to set the common registration place beforehand, so that the stealing risk of the user account is prominently reduced, the security of the user account is improved, the user operation complexity is decreased, and better experience is brought to the user. Furthermore, the embodiment of the invention further provides an abnormity monitoring device for the user registration.

The invention relates to a public payment security protection system based on artificial intelligence, in particular to the technical field of payment security, and the system comprises a collection module which is used for collecting the transaction information and transaction environment information of a first interaction body and the credit information of a second interaction body in real time; the storage module is used for storing transaction records of the first interaction main body and is connected with the acquisition module; the analysis module is used for analyzing the transaction security of the first interaction main body and the second interaction main body, is connected with the acquisition module, and is also used for judging the security of the transaction environment of the first interaction main body according to the transaction position of the first interaction main body; the judgment module is used for carrying out transaction safety judgment according to the safety analysis result and is connected with the analysis module; and the alarm module is used for carrying out corresponding transaction early warning according to the transaction security judgment result and is connected with the judgment module. According to the invention, the transaction security of public payment is effectively improved.

The invention relates to a safety detection method and system for remote login risk control. The method comprises the following steps of acquiring a login site of a current user, and verifying whetherthe current login site is a common login site of the user or not; if the current login site is not the common login site of the user, detecting whether user login equipment is the common equipment ornot; if the user login equipment is not the common equipment, acquiring the current position of the common equipment of the user; if the common equipment of the user does not exist in the preset range of the current equipment, judging that a dangerous login behavior exists at present; if the current user inputs login information, detecting whether the current user inputs a remote login special character or not; if the current user does not enter the remote login special character, judging that the dangerous login behavior exists at present; if the preset number of dangerous login behaviors exist in the single login, judging that the login is the abnormal login, recording the login behavior and exiting the login.

The invention discloses a method, system and device for dynamically generating an authentication code based on CDMA. The method includes the steps of: the mobile station and the authentication center randomly share security information according to the IMSI International Mobile Subscriber Identity Code, the ESN electronic serial number and the RANDSSD respectively. The data uses the MD5 algorithm to generate a private key; the mobile station and the authentication center use the DH algorithm to generate a public key according to their respective private keys; the mobile station and the authentication center exchange the public key with each other to obtain the other party's public key ; The mobile station and the authentication center use the DH algorithm to generate the authentication code according to their respective private keys and the public key of the other party. Therefore, the present invention dynamically generates an authentication code during the interaction process between the mobile station and the authentication center, and uses the dynamically generated instead of the fixed authentication code to perform authentication, which greatly reduces the risk of the authentication code being stolen, and greatly improves the authentication efficiency. security of rights.
