Abstract: A method and system for securing hosting web pages from malicious third party modules. The method includes uploading a third party module to a hosting web page; validating a proxy API call received from the third party module, wherein the proxy API call includes at least a payload parameter provided by the third party module; generating an engine API call including at least the payload parameter; validating the engine API call; and executing the payload parameter if the engine API call is validated.

Abstract: A computer-implemented method and system is provided for tracking a cumulative number of identifiable visitors to different objects (S1, S2 . . . SN), each of which may be visited by multiple visitors. A data structure is adapted to contain records relating to each object (S1, S2 . . . SN) and to each combination of two or more objects (S1S2, S1S3, . . . S1SN, S2S3, S2S4, . . . S2SN, S1S2S3, S1S3S4, . . . S1SN?1SN etc.). For each visitor visiting an object (SM) for the first time there is determined a current combination of objects previously visited by the visitor. If no objects have been previously visited by the visitor, a respective record relating to the object (SM) is incremented; and if objects have been visited by the visitor, the record relating to the current combination is decremented and the record relating to the combination of the object (SM) with the current combination is incremented.
