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.

Abstract: A method for rendering data of a three-dimensional image adapted to an eye position and a display system are provided. The method is used to render the three-dimensional image to be displayed in a three-dimensional space. In the method, a three-dimensional image data used to describe the three-dimensional image is obtained. The eye position of a user is detected.

When coordinating the physical characteristics of a display panel and the multi-optical element module, a plurality of elemental images can be obtained. The elemental images form an integral image that records the three-dimensional image data adapted to the eye position, and the integral image is used to reconstruct the three-dimensional image.
