A patent on the algorithm is pending.<\/p>\n<p>&#13;<br \/>\n\u201cWe treat regular ratings as noise, but we can detect patterns from users who are colluding to unfairly manipulate ratings,\u201d she said.  \u201cIt\u2019s designed to improve the quality of the information in the rating systems to make them more reliable.\u201d<\/p>\n<p>&#13;<br \/>\nSun explained that systems already exist that can detect obvious efforts to manipulate ratings, but current algorithms cannot detect \u201csmart attackers\u201d who try to make subtle changes to a product\u2019s rating.   Her new algorithm is more successful at detecting these subtle manipulations.<\/p>\n<p>&#13;<br \/>\nTo test its effectiveness, Sun is inviting computer users to try to manipulate a rating system protected by her algorithm.  A $1,000 prize is offered to the individual or team that can introduce the largest bias in the rating system.<\/p>\n<p>&#13;<br \/>\n\u201cWe hope that the contest will enable us to collect a lot of attack data, which can be used as a benchmark for testing our algorithm and future algorithms,\u201d said Sun.  \u201cIt\u2019s the best way to test it against real attackers.\u201d<br \/>&#13;<br \/>\n&#13;<br \/>\nThe contest begins April 25 and runs through July 30.
