Patent ID: 7343627

Claim:
A hard-drive, document-task-data, storage-avoiding non-retention method for the secure handling of document task data in a computer work environment in relation to the performance of a task, or tasks, (1) relating to such data, and (2) involving at least one of the functions including (a) scanning, (b) copying, (c) printing, and (d) faxing, and wherein, with regard to performance of such a task, there is a user interface through which the task is initiated and implemented by a user, and memory structure which may receive, and, during task performance only, random-access store, at least a portion of such data as a consequence of such initiating and implementing of the task, said method comprising prior to document-data introduction into that environment, preemptively narrowing the prospective scope of permitted outside access and inter-engagement which will be permitted to such data during the time when that data will be entered and present in the environment, so as to limit such access and inter-engagement substantially solely to direct local implementation of the user-selected task(s), and to no other external influence, said narrowing selectively including disconnectively isolating the computer work environment in a partial-only manner relative to any flow of task data between that environment and the outside world, with said partial-only isolating being defined by blocking such document data from any access to hard-drive storage without blocking other access to the hard drive, introducing the data into the narrowed-access environment, implementing the selected task(s), upon completion of the task(s) implementation(s), preventing any task-data retention through ridding the environment of any memory-structure data-content related to the just-completed task(s), and after said ridding, disengaging the environmental scope-narrowing which was earlier created.
