发明名称 Human User Verification
摘要 Techniques for generating a human user test for online applications or services may include splitting the visual objects in an image into multiple partial images, and forming one or more alignment positions. At each of the alignment positions, some of the visual objects appear recognizable while some bogus visual objects also appear to prevent robots from recognizing the alignment positions. A user is requested to find the multiple alignment positions to return recognizable visual objects. A system determines that the user is a human user if the recognizable visual objects input by the user match the visual objects in the image.
