The application discloses a magnetotelluric data processing system suitable for highland and cold conditions, relates to the technical field of data processing, and determines a magnetotelluric acquisition area under highland and cold conditions, arranges a plurality of sensing points in the area, establishes a local communication fence at the sensing points to acquire magnetotelluric data, establishes the distribution relationship of the local communication fence in the magnetotelluric acquisition area, analyzes and determines the position of a data aggregation point, determines all the sensing points around the data aggregation point, establishes the corresponding relationship between the data aggregation point and the surrounding sensing points, adjusts the sensing points based on the corresponding relationship, performs trusted verification on the sensing points initiating data upload applications, establishes a synchronization chain based on the verification result, associates the synchronization chain to a data processing platform for uploading magnetotelluric data, establishes a plurality of categories of processing components to perform data processing on the magnetotelluric data, realizes safe data uploading, and improves the data acquisition and processing efficiency.

The application discloses a kind of based on blockchain intelligent monitoring equipment security protection method and system, it is related to the field of intelligent monitoring.The application designs the dual authentication mechanism of blockchain-intelligent monitoring equipment to prevent illegal access;Based on asymmetric encryption (RSA) and symmetric encryption (AES) hybrid encryption, a monitoring data encryption storage mechanism is designed, to protect the privacy of users on intelligent monitoring equipment from being disclosed;Through blockchain technology, the interaction data of all user devices are recorded and the use rights of users are clarified, so as to prevent the data of intelligent monitoring equipment from being tampered with, and thus to ensure data credibility.Therefore, the intelligent monitoring equipment security protection method and system can effectively prevent the login authentication risk, privacy leakage risk and data tampering risk in the data access and interaction process, and improve the security of the data access and interaction process.

The invention relates to the technical field of power data regulation and control, and provides a power data access control method, device and system and a medium. According to the implementation scheme, a power data access request of a user is responded, request data carried in the power data access request is verified, and a verification result is obtained; if the verification result is that the verification is passed, automatically triggering a context information collection interface to collect multi-dimensional power data of the user so as to generate a multi-dimensional feature vector of the user; performing anomaly detection on the multi-dimensional feature vector through a pre-trained anomaly detection model to obtain an anomaly score; performing anomaly prediction on the multi-dimensional feature vector through a pre-trained classification model to obtain a risk probability value; and determining a target access strategy based on the request data, the business dimension data in the multi-dimensional power data, the anomaly score and the risk probability value, so as to execute a target action according to the target access strategy. According to the embodiment of the invention, intelligent security control on the power data access request can be realized.

The application discloses a user login verification method and device, equipment, storage medium and product, and relates to the technical field of network security, and comprises the following steps: in response to a login request of a target user, performing pre-information verification on the target user to obtain a pre-information verification result; when the pre-information verification result is verification success, performing risk assessment on the target user according to login data of the target user to obtain a risk level; performing account verification on the target user based on the risk level to obtain a verification result; and when the verification result is account verification success, feeding back login success information to the target user; the method performs pre-information verification on the target user in response to a login request of the target user, and if the pre-verification is successful, performs risk assessment on the user according to login data, determines a risk level, and performs different mode security verification based on the risk level, so that the account security is comprehensively ensured, the login security is enhanced, and potential illegal access is effectively prevented.
