Problems solved by technology

"However, existing CAPTCHA mechanisms can be foiled by a practice known as "CAPTCHA farming," in which automated algorithms temporarily redirect a CAPTCHA question to a human user to answer the CAPTCHA question and then return to its illegitimate purpose
If cheap manpower is available, it may render existing CAPTCHA mechanisms completely useless

Embodiment Construction

[0012] By using human power, CAPTCHAs based on distorted character recognition or common sense problems can be cracked. However, the CAPTCHA, which is based on a problem that only a specific user can know, will not be cracked by using human power. For example, a question requiring information associated with a user's close friends cannot be answered by any person who is not familiar with the user. A CAPTCHA based on information related to the user's social circle and the user's social interaction is called a social CAPTCHA. These questions require information that can be obtained in social networks.

[0013] A social network gives its members the ability to communicate and interact with other members of the social network. In use, members join a social network and then add connections to several other members with whom they wish to connect. As used herein, the term "friend" refers to any other member with whom a member forms a connection, association, or relationship via a soc...

Abstract

A social CAPTCHA is presented for authenticating members of a 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 a social CAPTCHA may be determined based on affinity scores associated with connections to members, such that the challenge questions relate to information that is more likely to be familiar to the user. The difficulty of asking questions can be determined based on suspiciousness and used to select a CAPTCHA.

Description

Technical field [0001] The present invention relates to computer security, and particularly to preventing unauthorized personnel or computing algorithms from illegally using computing resources. Background technique [0002] The authenticity of a user interacting with a website can be determined in a variety of ways, such as a question-and-response test in which only the target user is likely to be able to answer. In this way, unauthorized use of computing resources by another user or automatic computing algorithm can be avoided. One type of inquiry question for automatic calculation algorithms is called CAPTCHA, which is an acronym for "Completely Automated Turing Test To Tell Computers and Humans Apart". The common type of CAPTCHA requires users to type letters or numbers based on distorted images that are difficult to interpret by computing algorithms, but relatively easy to interpret for humans. Requiring users to read distorted text for authentication prevents automated sy...
