In one embodiment of the present invention, a computer-implemented system for protecting from unauthorized reproduction data associated with one or more products that is communicated over a communications network includes one or more servers. The servers collectively receive data associated with one or more products matching search criteria specified in a search query received from a buyer computer, the data having been collected in response to communicating the search query to one or more databases in which data associated with one or more products is stored. The servers collectively communicate to the buyer computer the data for the matching products and communicate a software component to the buyer computer, the software component operable to provide a user associated with the buyer computer access to the data for the matching products, the software component further operable to disable one or more tools supported at the buyer computer for reproducing the data.
