Abstract
A method for operating a data processing system of a type that includes a first data processing entity located within a trusted environment and a second data processing entity located within an untrusted environment. The method includes a first step, executed at the first data processing entity, of operating a first software agent for detecting a presence of an information container of interest and for producing a modified information container by automatically identifying and at least one of removing, masking, or replacing at least one predetermined type of restricted or private information in the information container. A second step of the method transports the modified information container from the first data processing entity to the second data processing entity for further processing. The further processing may entail an analysis of the modified information container to locate and/or identify an undesirable software entity, such as a computer virus.
