  • Publication number: 20070285674
    Abstract: A system and method for controlled monitoring of pending document processing operations is provided. Each document processing request received by a document processing device is assigned a job name, which is then encrypted using a random static encryption key, resulting in a job identification. A user then logs onto the document processing device to view pending jobs, which are displayed to the user by only job identification. Those jobs with which the user is associated are then decrypted by the document processing device, allowing the user to view job information including status and file name. The user is thereby also able to modify or delete those pending jobs with which the user is associated. Once the job queue is empty, the random static encryption key is deleted and a new key is generated when a document processing request is received into the empty queue.

  • Publication number: 20070208915
    Abstract: The subject application is directed to a system and method for the secure and correct deletion of data files from a data storage that bypasses the file system of an operating system. A secure erase service receives a request from a system interceptor, which has intercepted a system call from an application. The interceptor component communicates with the secure erase service via an interprocess communication module. The erase service receives the erase request from the communication module and communicates the erase request to a secure erase library. Using the file information within the secure erase request, the secure erase library queries the file system of the data storage device to determine the location of data blocks containing the data for deletion. Upon locating the data blocks, the secure erase library then instructs the device driver, via a virtual file system, to overwrite the data blocks a predetermined number of times.
