Patent ID: 8171458

Claim:
A method for detecting a source-related risk associated with an object and generating an alert concerning the source-related risk comprising: obtaining at least one criterion of the source-related risk associated with the object; obtaining at least one threshold associated with the source-related risk and associated with the object; detecting an operation on the object; determining whether the operation satisfies the at least one criterion of the source-related risk; determining, based on a user reputation profile and the operation, whether the operation causes exceeding the at least one threshold, the user reputation profile comprising one or more of: a type of an author; an experience history of the author; a credibility of the author; a source information of the operation; and previous operations of the author, the user reputation profile generated by: creating an initial reputation profile with the type of the author, the experience history of the author and the credibility of the author; detecting every operation of the author in every object; determining whether an operation satisfies the at least one criterion of the source-related risk; determining whether an operation causes exceeding the at least one threshold; updating the credibility of the author with an operation, if the operation satisfies the at least one criterion of the source-related risk or if the operation causes exceeding the at least one threshold; and extending the experience history of the author with the operation and the object; and generating the alert if the operation satisfies the at least one criterion of the source related-risk, or if the operation causes exceeding the at least one threshold, wherein a computing system including at least one processor and at least one memory device connected to the processor performs the operation detecting, operation satisfaction determining, exceeding threshold determining, and the alert generating.
