Abstract:
1. A system for eliminating redundant notifications to subscribers, the system comprising: a notification fingerprinter which generates a fingerprint from the contents of a subscriber notification using a predefined fingerprinting method; a fingerprint comparator which compares a fingerprint of a previously-sent notification with a fingerprint of a waiting-to-be-sent notification; and a server which determines whether to send said waiting-to-be-sent notification to said subscriber based on a result of the comparing by said fingerprint comparator, wherein: the server determines to send said waiting-to-be-sent notification to said subscriber in response to the comparing by said fingerprint comparator yielding that said fingerprint of said waiting-to-be-sent notification and said fingerprint of said previously-sent notification do not match, the server determines to omit the sending of said waiting-to-be-sent notification to said subscriber in response to the comparing by said fingerprint comparator yielding that said fingerprint of said waiting-to-be-sent notification and said fingerprint of said previously-sent notification match, and said notification fingerprinter generates said fingerprint from a hash value of said subscriber notification and the probability that two different notifications will have the same fingerprint is below a predefined threshold, wherein:
