Description

New energy station communication facility identity recognition method and system

Technical Field

The invention belongs to the technical field of access control management, and particularly relates to a system and a method for identifying the identity of a communication facility of a new energy station.

Background

Access control management is a method for controlling the access rights of a user to a system or resource. It can manage the user's access rights according to the user's identity, time, location or functional requirements. The management mode can be used for limiting the authority of the user to access the communication facility of the new energy station, and ensuring that only the user with the authentication and the access authority can access.

Conventional access control methods typically use a static access control policy based on roles or permissions to restrict the user's access permissions. However, this approach lacks flexibility and cannot meet the needs of different users and scenarios. For example, time restrictions, area restrictions, or functional restrictions that cannot refine the user's access;

secondly, the conventional access control method only focuses on the authentication and authorization process of the user, and cannot monitor the access behavior of the user in real time and detect abnormal activities or unauthorized access. This may result in security risks not being perceived in time, increasing the security threat of the facility.

Example 1

Referring to fig. 1, a first embodiment of the present invention provides a method for identifying identity of a communication facility of a new energy station, including:

s1: and (3) carrying out identity verification on the user through a biological feature recognition technology and edge optimization, matching the user identity information with the access authority after the user passes the verification, and authorizing the user to access the new energy station communication facility according to the matching result.

The following identity recognition device is applied to metering scenes.

Furthermore, when the user requests to access the new energy station communication facility, the input module receives the user identity information and transmits the user identity information to the biological characteristic recognition module for identity verification, and the biological characteristic recognition module uses fingerprint, face, iris and voiceprint recognition to carry out identity verification on the user.

It should be noted that the access rights include time restrictions, area restrictions or functional restrictions,

the time limit comprises the steps of setting time period allowed access according to the access requirement of a user and the working time of a new energy station, setting time T epsilon [ x, y ] x is the earliest allowed access time, y is the latest allowed access time, when T < x, if any user applies access, the system automatically prompts to prohibit access, when x is less than or equal to T and less than or equal to y, if any user applies access, the area limit comprises a first-level area, a second-level area and a middle area according to the physical layout and the equipment position of the new energy station, wherein the first-level area only allows access of users with specific authority, the second-level area allows general users to access the middle area to connect the first-level area and the second-level area, and the temporary authority is stored; when a user requests to access the first-level area and the second-level area, the system judges according to the authority of the user, if the authority is insufficient, the user needs to apply for the highest authority manager, if the highest authority manager agrees, a temporary random key P is returned to the applied user and the middle area, the user accepts the key P and then applies for the second time after carrying out mixed encryption with an authority key Q contained in the user, at the moment, the middle area recognizes the mixed key and combines the biological feature recognition technology to judge whether the access is allowed, if the area requesting the access is within the authority range owned by the user, the access is allowed, when the user tries to access the limited function, the system judges according to the authority of the user, if the authority is insufficient, the access is forbidden, the user is prompted to have the authority insufficient and the key cannot be applied for the highest authority manager, at the moment, the system recognizes and refuses the access and uploads the key to a dispatching center for storage.

Access rights control: during the actual access of the user, the system will control the behavior of the user according to the current access rights. For example, for a user with high access rights, he may be allowed to access advanced functions and sensitive data; medium authority users access in-station functions and data, but are restricted from accessing certain sensitive information; and for users with lower access rights, only the users are allowed to access the public area and the non-sensitive data.

It should also be noted that when multiple users perform access requests and apply for new users at the same time, edge optimization control is triggered, so that data and calculation tasks in the authentication and access control processes are distributed to each node: the new user first makes reservation access, the normal user collects information through biological feature recognition, the identity verification request is sent to the edge computing node at the same time when collecting, after the edge computing node receives the request, the identity information of the user is initially verified through the biological feature recognition module, and if the initial verification is passed:

when a plurality of users access, the edge computing node sends the access control request of the users to the central server for further verification, after the central server passes the verification, the matching module matches the user identity information with the access authority stored in the storage module, and then the normal access work is authorized.

When the applicant is a new user, the edge computing node sends an access control request of the user to the central server for further verification, after the central server receives the access control request, the central server uploads the highest authority manager to check whether reservation records exist and combine the information according to the identity information and the access authority setting of the user and the application reason, and judges whether the new user can access the target resource, and the central server returns a verification result to the edge computing node: if the target resource is allowed to be accessed, the edge computing node generates a temporary access token and sends the temporary access token to the new user, and after the user receives the temporary access token, the temporary token is used for accessing the target resource and the record is saved to the central server.

The access token has time limit, and the token automatically fails after the time is exceeded, if the new user performs identity preservation application, the central server opens corresponding access rights after agreeing with the highest rights manager, and the reservation application is not needed when entering next time.

S2: in the user authentication process, the access log and the activity information of the user are recorded in combination with the self-adaptive access control, and the access behavior of the user is analyzed and monitored to detect abnormal activity or unauthorized access.

Further, after passing the authentication according to the biometric identification, the method is based on the location limitation, the time limitation, the area limitation and the behavior limitation: position limitation: and judging whether the user is in the area which is allowed to be accessed according to the position of the user.

Time limit: and judging whether the user has permission to access according to the current time and the preset time range.

Region restriction: and judging whether the user is in the range of the area which is allowed to be accessed or not according to the area where the user is located.

Behavior restriction: and judging whether the abnormal behavior of the user exceeds the limit times according to the behavior characteristics of the user.

Calculating a risk degree R (a):

According to the risk result, dynamically adjusting the access right of the user: when R (A) is more than or equal to mu, mu is E [0.5,0.8], the user is judged to be high in risk, access is refused, secondary identity verification is carried out, and monitoring and log recording are simultaneously carried out in real time;

when ω is R (a) < μ, the user is judged as risk of stroke, and limited access control and frequency are required;

when R (A) < ω, ω ε [0.3,0.5], then the user is judged to be low risk, allowing the access rights to be relaxed.

The self-adaptive access control strategy can dynamically adjust the access authority of the user according to the historical access record and the behavior mode of the user, thereby realizing intelligent management and control of the communication facilities of the new energy station. The method not only improves the safety and the management efficiency, but also provides more personalized access experience for the user.

S3: upon detection of abnormal activity or unauthorized access, a security alarm is triggered and corresponding security measures are taken, such as blocking access or notifying the relevant personnel.

Furthermore, an anomaly detection prediction model is established, the system collects access logs and access information of users in real time, analyzes and models the information, inputs a new sample into the model, and selects an optimal result:

F(X)＝Σ((u _i,j -c _v,j ) ² *θ)-∑((u _j -c _j ) ² *θ)

calculating the similarity of the optimal result:
