摘要： A social CAPTCHA is presented to authenticate a member of the social network. The social CAPTCHA includes one or more challenge questions based on information available in the social network, such as the user's activities and/or connections in the social network. The social information selected for the social CAPTCHA may be determined based on affinity scores associated with the member's connections, so that the challenge question relates to information that the user is more likely to be familiar with. A degree of difficulty of challenge questions may be determined and used for selecting the CAPTCHA based on a degree of suspicion.
