Abstract:
1. A computer implemented method for detecting whether a received information content is identical to any of a plurality of stored information contents, comprising the steps of: calculating a plurality of unique parameter values by applying an algorithm that calculates, for each of a plurality of stored information contents, a unique parametric value to a predetermined precision set by an organization, wherein each unique parametric value represents one of the plurality of stored information contents; storing the plurality at parameter values; receiving a new information content; responsive to receiving said new information content, applying said algorithm to said received information content to calculate a parametric value representing the received information content; comparing the parameter value representing the received information content with each of said unique plurality of stored parameter values; and indicating that the received information content is identical to a stored information content if the corresponding parameters values are equal; wherein said algorithm is:
