  • Patent number: 12335291
    Abstract: An information leakage detection method and a device using the same are disclosed. The method includes the following steps. Network connection data of an electronic device is obtained. Log data related to a (domain name system) DNS is extracted from the network connection data. A DNS request in the log data is analyzed to obtain multiple character distribution feature values according to an analysis result. The character distribution feature values reflect a character distribution status of a domain name in the DNS request under different classification rules. A machine learning model determines whether the DNS request is a malicious DNS request according to the character distribution feature values, and the malicious DNS request is used to carry leaked data to a remote host.

  • Publication number: 20250070653
    Abstract: An electromagnetic interference suppression method for at least one power supply is provided. Each of the at least one power supply includes a first conversion circuit and a second conversion circuit. The first conversion circuit receives an input voltage and outputs a first output voltage. The second conversion circuit receives the first output voltage and outputs a load current. If the input voltage received by the first conversion circuit of the at least one power supply is a DC voltage, an electromagnetic interference suppression operation is performed. Then, the electromagnetic interference suppression operation is performed to determine whether the load current is greater than a preset current and lower than an upper current limit. If the determining condition is satisfied, the first output voltage is dynamically adjusted, and a peak-peak value of the first output voltage is not zero with the varying load current.
