What does "Passive Detection" mean?
Table of Contents
Passive detection refers to methods that identify objects or actions without needing to actively probe or interfere with them. Instead of sending out signals or actively searching, these techniques rely on observing the natural signals or traits that objects emit or reflect.
Deepfake Detection
In the context of deepfakes, passive detection looks for signs that a video, image, or audio has been altered or created using artificial intelligence. This method can analyze different types of media, such as photos, videos, or sounds, to identify inconsistencies that suggest manipulation. By considering various formats together, researchers aim to improve the ability to spot deepfakes, while also addressing issues like how well these methods work across different types of fake content.
UAV Detection
When it comes to identifying small flying drones, or UAVs, passive detection techniques monitor the natural signals emitted by the drones. A notable method uses radar to capture the small movements of the drone without needing to know its specific type or how it moves. This approach allows for accurate detection, even in challenging conditions, and can track the drone's location effectively.
