Recently, Google has introduced a new feature called "Circle to Search" in the Android system, aiming to help users quickly determine the authenticity of images. This feature, through the added "About this image" label, can instantly display the metadata and source information of the image, and check for the presence of Google AI watermark as a basis for judging the authenticity of the image.

This innovative tool is particularly useful for political images that frequently appear on social media, detached from their original context. It provides users with a convenient means of verification, reducing the spread of misleading information. Users can obtain key information without leaving the application, enabling them to make wiser judgments.

Currently, this feature is gradually being rolled out on the latest Pixel series, as well as some Samsung smartphones, tablets, and foldable devices. Google's move signifies an important step in combating false information and improving user experience. In the future, with the continuous advancement and popularization of technology, it is expected that more devices and applications will integrate such features, collectively creating a more authentic and trustworthy digital environment.
