Abstract

This application relates to a remote login method and server based on security verification in a KVM system. The method includes having the server receive verification data sent by a local device and perform security verification on the verification data.

[0065] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, it can run on a terminal. Figure 1 This is a hardware structure block diagram of the terminal for the remote login method based on security authentication in the KVM system of this embodiment. For example... Figure 1 As shown, a terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 and a memory 104 for storing data are also included.

[0068] This embodiment provides a remote login method based on security authentication in a KVM system, applied to the server side. Figure 2 This is a flowchart of a remote login method based on security authentication in a KVM system according to this embodiment, as follows: Figure 2 As shown, the process includes the following steps:

[0069] Step S20: Receive verification data sent by the local device and perform security verification on the verification data.

[0070] The verification data is a dataset obtained by adding validation data to the user's biometric data collected locally. The purpose of this verification data is to validate the validity of the user's identity uploaded by the local device. Only when the user's identity matches the data within the preset mapping relationship in the server is the user currently logging in considered legitimate.

[0071] It is important to note that the object of security verification in this step is the verification data extracted from the verification data, not the verification data itself.

[0072] Step S30: If the security verification is successful, extract biometric data from the verification data, retrieve the biometric data from the pre-stored mapping relationship, and determine the login information corresponding to the biometric data.

[0073] As mentioned above, the object of security verification is the validation data within the verification data. If the aforementioned verification data successfully passes security verification, biometric data representing the user's identity information for remote login can be extracted from the verification data. The server then retrieves the corresponding login information based on a preset mapping relationship. This login information serves as the login credentials for logging into the remote device.

[0074] Step S40: Convert the login information into encrypted login data and send the login data to the remote device associated with the local device for login.

[0075] Instead of directly sending the login information obtained in the previous step to the remote device, the account data and key contained in the login information are converted into login data such as keypad codes. At the same time, the obtained login data is encrypted, and finally the encrypted login information is sent to the remote device for login.

[0076] In the above method, by performing security verification on the verification data, if the security verification is successful, the biometric data in the verification data is extracted for remote device login. By performing the operation of verifying the validity of the representative user, it is possible to effectively prevent unauthorized users from stealing biometric data to log in to remote devices, thereby improving the security of data during the remote login process.

[0077] In one embodiment, the remote device login method further includes:

[0078] Step S50: If the security verification fails, delete the verification data;

[0079] Step S60: Generate alarm information to be sent to the local device based on the verification data.

[0080] In implementation, the aforementioned embodiments provide the operational procedures after the verification data passes security verification. It is worth noting that if the verification data fails security verification, it indicates an anomaly in the verification data. As the principle of verification data generation dictates, only unauthorized intrusion will cause the environmental values ​​used to generate the verification data to change relative to a secure state. In other words, the only reason for failing security verification is unauthorized intrusion. Therefore, once an anomaly occurs indicating that the entire verification data, including biometric data and verification data, is insecure, the only solution is to delete all verification data and generate an alarm message sent to the local device, indicating that unauthorized intrusion may have occurred on the local device.

[0081] It is worth noting that step S60 includes:

[0082] Step S62: Perform reverse calculation based on the verification data to obtain the suspicious environment value.

[0083] Step S64: Send the suspicious environmental value as an alarm message to the local device.

[0084] In implementation, considering that the alarm information sent to the local device needs to clearly reflect the details of potential unauthorized intrusion, this embodiment uses verification data as the primary method for generating alarm information. Since the verification data is generated based on the local device's environmental values, a reverse calculation method is used: the verification data is used to perform reverse calculations to obtain suspicious environmental values ​​reflecting unauthorized intrusion behavior, and these suspicious environmental values ​​are then sent to the local device as alarm information. This allows the local device to easily obtain relevant parameters indicating an unauthorized intrusion by simply comparing the suspicious environmental values.

[0085] In one embodiment, the login information is converted into encrypted login data, and the login data is sent to a remote device associated with the local device for login. Step S40 includes:

[0086] Step S42: Extract the account data and key used for login from the login information;

[0087] Step S44: Translate the account data and key to obtain the corresponding login data, encrypt the login data, and send the encrypted login data to the remote device for login.

[0088] In implementation, the login information includes account data and keys used for login. Considering that directly transmitting account data and keys to remote devices would pose significant security risks, the obtained account data and keys are converted into login data for the login device. For example, when the login device is a keyboard, the corresponding login data is the keystroke code generated by pressing a key.

[0089] When login data, such as keystrokes, is encrypted before being transmitted to a remote device for remote login, the increased conversion and encryption of account data and keys to login data significantly improves the security of remote device login compared to the commonly used method of directly transmitting login information.

[0090] In one embodiment, before receiving the verification data sent by the local device, i.e., step S20, the method further includes:

[0091] Step S10: Construct a mapping relationship that includes biometric data and login information.

[0092] In practice, to ensure the smooth execution of step S30, step S10 needs to be executed before step S20 to establish the necessary mapping relationship. This mapping relationship represents the correspondence between each user's biometric data and the login information required by a remote device. Biometric data includes unique information that reflects the validity of each user. For security and ease of use, typical biometric data includes facial features, fingerprints, and other biometric information.

[0093] Because biometric data has high anti-counterfeiting properties, using biometric data to obtain login information on the server side can provide a more secure login environment compared to the existing technology of directly logging into devices using usernames and passwords.

[0094] Secondly, this application also provides a remote login method based on security authentication in a KVM system, for use on the local device side, such as... Figure 3 As shown, it includes:

[0095] Step S70: Collect the user's biometric data.

[0096] Here, biometric data serves as the unique information that reflects the validity of each user. For security and ease of use considerations, typical biometric data includes facial features, fingerprints, and other biological information.

[0097] Step S80: Add verification data to the biometric data to obtain verification data.

[0098] In order to obtain the verification data sent to the server, it is necessary to add verification data representing the current environmental value of the local device to the existing biometric data. Since unauthorized intrusion will cause a significant change in the current environmental value compared to the state without unauthorized intrusion, the verification data can serve as an indicator of whether an unauthorized intrusion has occurred.

[0099] Step S90: Send the verification data to the server for security verification. After passing the security verification, obtain the login information to log in to the remote device.

[0100] Once the verification data with added validation information is obtained, it is sent to the server. The server will then perform security verification on the verification data and handle subsequent operations such as remote device login.

[0101] In one embodiment, after collecting the user's biometric data, i.e., step S70, the method further includes:

[0102] Step S72: Generate verification data related to biometric data based on the environmental values ​​at the current time.

[0103] In practice, the basis for generating verification data is environmental values, specifically the environmental values ​​of the local device at the moment the verification data is generated. These environmental values ​​include parameters such as time, IP address, and the MAC address of the local device. The algorithm for generating verification data based on these parameters can be calculated using methods including weighted summation, which will not be elaborated upon here.

[0104] In one embodiment, it further includes:

[0105] Step S92: Receive alarm information sent by the server, extract suspicious environmental values ​​from the alarm information and perform security checks.

[0106] In practice, if the verification data fails the security verification, the local device will receive an alarm message from the server. At this time, step S92 needs to be executed to extract suspicious environmental values ​​from the alarm message so as to analyze the suspicious environmental values ​​to determine the details of the illegal intrusion.

[0107] The present embodiment will now be described and illustrated through preferred embodiments.

[0108] Figure 4 This is a detailed flowchart of the remote login method based on security authentication in the KVM system of this preferred embodiment.

[0109] Step S301: Collect the user's biometric data.

[0110] Step S302: Generate verification data related to biometric data based on the environmental values ​​at the current time.

[0111] Step S303: Add verification data to the biometric data to obtain verification data.

[0112] Step S304: Send the verification data to the server for security verification.

[0113] Step S305: Receive verification data sent by the local device and perform security verification on the verification data.

[0114] Step S306: If the security verification is successful, extract biometric data from the verification data, retrieve the biometric data from the pre-stored mapping relationship, and determine the login information corresponding to the biometric data.

[0115] Step S307: Convert the login information into encrypted login data and send the login data to the remote device associated with the local device for login.

[0116] In step S308, if the security verification fails, the verification data is deleted, and an alarm message is generated and sent to the local device based on the verification data.

[0117] Step S309: Receive alarm information sent by the server, extract suspicious environmental values ​​from the alarm information and perform security checks.

[0118] By performing security verification on the verification data, and if the verification passes, the biometric data in the verification data is extracted for remote device login. By performing the operation of verifying the validity of the user, it is possible to effectively prevent unauthorized users from stealing biometric data to log in to remote devices, thereby improving the security of data during the remote login process.

[0119] It should be noted that in the above steps S301 to S309, the local device executes S301-S304 and S309; ​​the server executes S305-S308. Because multiple execution entities are involved, this is specifically combined... Figure 4 Please provide an explanation.
