Abstract: The present disclosure prevents the leakage of user data by preserving user data working not in an electronic computing machine. A part of a storage area of a main memory of a user terminal is used as a RAM disk. User data working is encrypted and stored in the RAM disk. The user data stored in the RAM disk is sent to a network storage, the RAM disk and the network storage are synchronized. Since the user data is controlled by using a driverware technology inside the electronic computing machine, and sent to the network, therefore the security is ensured.

Abstract: The present invention provides a data management program for performing monitoring so that user data provided to the client cannot be copied and utilized for a purpose other than the intended purpose. When a storage device (8) storing user data (3) is connected to a client computer (12), a management program (4) prohibits writing to all of the external storage devices. The management program (8) makes settings prohibiting usage of a network (7). The management program (4) performs control by acquiring the file name, folder name, and attribute data of the execution file as well as the process name and process ID of the process being executed. The management program (4) has built-in driverware (50) which runs in the kernel mode (15) of an operating system (21) and serves to provide a common interface for the communication of device drivers (35, 36, 42 to 44) and an application program (20).

Abstract: [Task] When data is printed to a printing device from a computer, the printing is approved or not approved according to the data contents. [Solution] A first control filter 23, which detects printing data output from a spooler 10, halts the printing task temporarily, and replicates the printing data, and a viewable image driver 20 which uses replicated printing data to create an image file, are provided. The image file is transmitted over a network 2 to a manager, and the manager views the image file and decides whether to perform printing on the printing device 4, and transmits a notification signal to this effect to the first control filter 23. The first control filter 23 performs printing control according to the notification signal from the manager.

Abstract: In the method of controlling a file system driver of an electronic computer and the program for the method and further the storage medium containing the program according to the present invention, access to a file stored in a storage device of the electronic computer is controlled in a kernel mode. When a specific file in a file system of an electronic computer (11) is accessed from an application program (4), the access is received in a kernel mode (8) of an OS (3). Then, an access control database (36) comprising filenames in the file system and access methods is referenced to judge whether or not the access to the specific file conforms to conditions prescribed in the access control database (36). If the access to the specific file does not conform to the conditions, the access is canceled.

Abstract: A method for preventing a return address from being falsified due to a buffer overflow during the program execution, and for detecting the buffer-overflow beforehand. When the return address is re-written during program execution, the debug function of the central processing unit is used to output an error. The falsification of the return address is detected through the error output. Then the falsified return address is re-written to a value stored in advance to enable the program to return to normal operation. When the falsification of the return address is detected, the executing program is terminated.

Abstract: A computer storing a print control program, the program, and a recording medium containing the program according to the present invention control access from the computer to a printer in the kernel mode. When access is made from an application program (4) to a printer (69), a spooler (65) operates. An access request is detected in response to an event occurring when the spooler (65) operates. A common interface driver (7) controls data output to the printer (69) at a filter (41) or the spooler (65) according to a control condition previously registered in a control condition database (36).

Abstract: A screen image for monitoring the usage state of a client computer is acquired, the acquired screen image is efficiently stored, and the stored screen image can be easily searched. A draw command is acquired by a driverware (22) when a screen image is generated in a client computer (2), and text data is extracted from the draw command. The extracted text data are associated with the draw command and stored in a database (13) of the server (3). The database (13) is searched using a keyword, and the screen image is reproduced from an associated draw command.

Abstract: When user data and a program stored in a computer is recorded into an electronic recording medium by a recording device connected to the computer and carried outside, its recording is limited. The data management program stored in a computer has a function used when writing data from the computer onto the recording medium, for authenticating a user and disabling a person other than the authorized person to perform writing. The data management program authenticates whether the user is an authorized person by using a USB memory containing a secret key for authentication.
