  • Patent number: 7647402
    Abstract: Protecting data files from being stolen or compromised in a data processing operation having stored data in a plurality of data files by receiving user requests for access to data files, determining whether said requests are unauthorized intrusions into the requested data files and, responsive to a determination that a request is an unauthorized intrusion, changing the identification of the requested data files by renaming the files. Preferably, the rename should be one which does not identify the contents of the file, i.e. the rename disguises the file contents. Then, it is also desirable that the renamed file be moved to a new “hidden” directory. In such a case, the renamed file is also assigned a covert name which indicates a covert location in the new directory. Then, there is provided a log referencing each renamed file to the covert name of the respective file so as to indicate the covert location of said file in said new directory.

  • Patent number: 6829767
    Abstract: A method, system and computer readable instructions for executing a file with a file format is provided. An attempt is made to execute the file with a first computer application within a plurality of computer applications. Responsive to the first computer application being unable to recognize the file format of the file, a second computer application within the plurality of computer applications is selected to execute the file. The file is then executed using the selected second computer application.

  • Patent number: 6711644
    Abstract: An apparatus and method for communicating the completion of asynchronous I/O requests is provided. In particular, the apparatus and method make use of a new function call which is capable of waiting for a predetermined number of I/O requests to be completed prior to returning to the calling application. Control blocks for the I/O requests are updated after a predetermined number of I/O requests have been completed, i.e. in a process context rather than in an interrupt context as in the known systems. In this way, the overhead associated with known asynchronous I/O system calls is reduced.

  • Publication number: 20020129152
    Abstract: Data files are protected from being stolen or compromised by unauthorized users by a system comprising receiving user requests for access to data files, means for whether said requests are unauthorized and means for destroying the requested data files responsive to a determination that a request is unauthorized for such files. The present invention offers a very aggressive solution to the problem of theft of data in files. At the first suspicion of intrusion, there is a set up for destroying the intruded files. It would be advantageous to have duplicate or backup files for all files. These duplicates must be substantially inaccessible to user requests.
