Abstract: A method, system or computer usable program product for masking communication data using context based rules including intercepting a communication between a server and a client by an intermediary, the communication having a recipient, parsing the communication by the intermediary to determine whether a context based alteration rule should be applied, responsive to an affirmative determination, applying the rule to the communication to produce an altered communication with altered data, and sending the altered communication to the recipient so that the altered data in the communication is utilized in a masked manner.

Abstract: Briefly, some embodiments of the invention provide, for example, devices, systems and methods for storage and access of computer files. A method in accordance with an embodiment of the invention may include, for example, receiving from a remote site a request to access a first file having a plurality of blocks, said request having a pre-defined format encapsulating an original request of a client of a synchronous client-server system and in accordance with a pre-defined file system; determining, for each of at least some of said plurality of blocks, a differential portion representing a difference between each said block and a corresponding block of a second file; and sending said differential portion to said remote site.

Abstract: A method and system providing a distributed filesystem and distributed filesystem protocol utilizing a version-controlled filesystem with two-way differential transfer across a network is disclosed. A remote client interacts with a distributed file server across a network. Files having more than one version are maintained as version-controlled files having a literal base and at least one delta section. The client maintains a local cache of files from the distributed server that are utilized. If a later version of a file is transferred across a network, the transfer may include only the required delta sections.
