The response includes a plurality of response characters that includes the plurality of challenge characters drawn in a response region. The drawing the response characters includes drawing a first response character, calculating a second set of coordinates for a second response character, and drawing the second response character. After all of the response characters have been drawn, locations of each of the challenge characters within the response are identified, and a maximum allowed distance is calculated based on the identified locations of the challenge characters within the response."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Unicode-based image generation and testing","description":"Systems and methods for testing to tell computers and humans apart and generating said tests are described.
