摘要： A file differencing and updating system is provided that includes a file differencing component and a file updating component. The file differencing component, or file differencing engine, generates a difference file in a first processor-based or computer system from an original or old version and a new version of an electronic file. Generation of the difference files includes processing to reduce the number of file changes introduced by code block swaps. The processing uses an alignment algorithm, which includes a sorting algorithm, to align the code blocks of the original version in the same order as those of the new version, thereby eliminating the increase in the number of byte-level file differences due to code block swaps. During the alignment operations, the block movements are dynamically recorded at a minimum cost level and encoded for transmission to the file updating component for use in code recovery.

摘要： Systems and methods are provided for pre-processing original and new versions of files as part of difference file generation between the original and new file versions, for example byte-level file differencing. Software/executable changes between file versions include primary changes/logical changes, which are defined to be the source code changes, and secondary changes. The secondary changes generally result from the primary changes and are generated by the software compiler/linker utilities. The secondary changes include address changes, pointer target address changes, and changes in address offsets. The pre-processing systems and methods provided use approximation rules between file versions to remove/reduce the secondary changes and encode information relating to the removal of these changes in information of the corresponding difference file.

摘要： Devices and methods are provided for generating difference files that include encoded differences between byte streams of original and new file versions. Generation of the difference files includes processing by components of an optimizing system and/or algorithm to identify replacement content in a first area of the new byte stream. The replacement content includes a group of bytes of the new byte stream identified as at least one of byte insertions and byte replacements in a corresponding operation array. The optimizing system identifies content similarities between the replacement content and at least one of the original byte stream and a second area of the new byte stream. The optimizing system generates information of the difference file by encoding information of the content similarities.

摘要： A system and method provides a graphical user interface (GUI) for users to monitor and manage sensitive information within an enterprise network. The GUI can provide users with information, such as the presence of input/output devices (I/O device), the location of documents containing sensitive information (sensitive documents), and the status of local security policy. The GUI can also provide users with real-time information, such as the occurrence of local security policy violations, the life-cycle of sensitive documents, and the sensitive information dynamic flow within the enterprise network.
