1. A method for detecting at least one dishonest rater in a rating system, the method comprising the steps of:
- entering, by a plurality of raters, respective ratings with respect to at least one entity to be rated;
storing the entered respective ratings;
calculating a first individual value for a first rater of the plurality of raters based on the respective rating entered by the first rater;
calculating a second individual value for at least one second rater of the plurality of raters based on the respective rating entered by the at least one second rater;
determining an indication value for the first rater based on the calculated individual values, the indication value representing a degree of honesty of the first rater;
comparing the determined indication value to a predetermined dishonesty threshold; and
classifying the first rater as dishonest if the indication value is equal or higher than the predetermined dishonesty threshold.

Abstract
A system and method for detecting a dishonest rater participating in a rating system is provided. Raters enter ratings regarding at least one entity which can be rated, and the ratings are stored. Individual values for the raters are calculated based on the ratings entered by the respective rater, and an indication value is determined based on the calculated individual values. The indication value is compared to a predetermined dishonesty threshold, and the rater is classified as dishonest based on the comparison result.
