  External recording media (devices) are increasing in storage capacity and can easily carry a large amount of information, contributing to operational efficiency. However, as described above, business using conventional external recording media In many cases, the efficiency of information processing is related to information leakage prevention, and the computer environment is related to the restoration of the environment. The present invention plays a role in preventing information leakage, and allows a user to maintain an adjusted work environment at any location according to his / her business, so that business can be performed without choosing a location. It is an object of the present invention to provide a method capable of maintaining the environment of the terminal device.

  In order to solve the above problem, according to one aspect of the present invention, in a system configuration in which the first and second terminal devices and the server are connected via a communication line, the first terminal device has a predetermined first Information about the environment is stored in the first terminal device, and a step of storing information on the second environment used during operation of the terminal device in a predetermined storage means by the first terminal device; A step of detecting an event; a step of detecting a third environment different from the first environment in the second environment when the event is detected; and information relating to the detected third environment to the terminal device A step of storing in a storage device provided, and a step of transmitting information relating to a first environment to the server via the communication line, wherein the server transmits the first information transmitted from the first terminal. Receiving information about the first environment from the server by the step of storing information about the border and the second terminal device, storing the information in the storage means of the second terminal device, and the storage device A step of detecting connection to the terminal device, a step of reading information on the third environment from the storage device, and a predetermined storage unit of the second terminal device for reading the information on the third environment And an operation method for a plurality of environments.

  Here, the first and second environments are an operational system (OS), various driver software, application software (hereinafter referred to as an application), wallpaper on a display screen, an array of icons, a document file, an image file, the Internet. Connection information and various address information.

  In addition, the event refers to a power-off on the OS, a timing when a user presses a predetermined key for termination processing of the terminal device, and the like.

  In this way, the environment of a certain terminal device is divided into a first environment originally installed in the terminal device and a second environment set for each user, and the user uses the terminal device. When finished, the difference environment between the first and second environments is set as the third environment, and information on the third environment is stored in the portable storage device or the like. Therefore, the terminal device used by the user is It is sufficient to install (or create an environment) information about the first environment. Therefore, it is possible to standardize the environment of each terminal device, and for example, maintenance of the terminal device becomes easy.

  FIG. 1 is a schematic diagram showing a configuration example according to an embodiment of a terminal device 1 according to the present invention. In the figure, the terminal device 1 includes a CPU, a memory, a disk unit (hard disk, flexible disk, etc.) as hardware, an input / output unit 62 such as a printer, a display, a keyboard, a mouse, etc., and an external storage device 60. A storage unit 80 is provided that is detachable via the output interface unit 40 and uses hardware such as a hard disk. The storage unit 80 is displayed outside the terminal device 1, but may be provided in the terminal device 1, and the operating unit (OS) and various software are installed in the storage unit 80. The storage unit 80 of the terminal device 1 stores filed information of the operation system file 82, the update log file 84, the update data file 86, and other files 88.

  In the operation system file 82, an OS and various application software necessary for normal operation of the terminal device 1 are stored as files. When these are executed by the terminal device 1, the operation unit 211, It functions as a write monitoring unit 212 and a read monitoring unit 213. The operation unit 211 executes these functions when the terminal device 1 executes the OS and application software stored in the operation system file 82.

  In the update log file 84, a history of data updated by the writing process is stored as log information. In the update data file 86, data to be newly written when a write process is performed is written as update data. That is, update data that should normally be written to the operation system file 82 is written to the update data file 86, and the data before update is held in the operation system file 82 as it is. Needless to say, data that is not updated, that is, unupdated data is also held in the operation system file 82 as it is.

  Next, the internal functions of the terminal device 1 other than the operation unit 211, that is, the functions of the write monitoring unit 212 and the read monitoring unit 213 will be described.

  The write monitoring unit 212 monitors the writing of data to the operation unit 211, that is, the hardware, firmware, and the operation system file 82 by the OS and applications, and when data writing occurs, the new data is transferred to the operation system file 82. Instead, the update data file 86 is written and stored as update data, and the history is recorded in the update log file 84.

  The read monitoring unit 213 monitors data read from the operation unit 211, that is, OS, application hardware, firmware, and the operation system file 82. When data read occurs, the update data of the data is an update data file. If the update data file 86 does not exist in the update data file 86, the corresponding data is read from the operation system file 82.

  Next, the operation of the terminal device 1 configured as described above will be described with reference to the flowchart shown in FIG. When the terminal device 1 is powered on and the process is started, the operation unit 211 detects the startup of the terminal device 1, determines the presence or absence of the external storage device 60 (step 500), and The file is read through the device driver stored in the other file 88 of the storage unit 80 (step 502). The read file stored in the external storage device 60 is written to the update data file in the storage unit 80 (step 504).

  In the normal operation state, the terminal device 1 is in a state of waiting for data writing or reading, and the writing monitoring unit 212 monitors data writing, and the reading monitoring unit 213 monitors data reading. When data writing occurs (YES in step 506), the write monitoring unit 212 records newly written data as update data, the data name and time in the update log file 84 (step 508), and updates the update data itself. The data file 86 is saved (step 510). Therefore, at this time, the data before update of the data with the same name is stored in the operation system file 82 which is the original storage location, and the updated data is stored in the update data file 86 as update data. It will be. Thereafter, when there is an instruction to end (in the case of YES at step 512), the update data file 86 is read (step 514), written to the external storage device 60 (step 516), and the terminal device 1 However, if there is no instruction for termination (NO in step S512), the process returns to step 506 and the operation state is continued as it is.

  3A is a schematic diagram showing the storage contents of the update log file 84, and FIG. 4A is a schematic diagram showing the storage contents of the update data file 86. In the update log file 84, for example, as shown in FIG. No. 1 data as “A” was updated at 0100 o'clock (3:00 am) on March 30, 2008; No. 2 data “B” as the information of No. 2 was updated at 0130 (1:30 am) on March 30, 2008. No. 3 data “C” was updated at 03:00 on March 30, 2008 (1:31 am). 4 as No. 4 information. It is recorded that the data named “A” in the information 1 was updated at 0200 o'clock (2:00 am) on March 30, 2008. In the update data file 86, as shown in FIG. The update data itself of the data “A”, “B”, “C”, “A” is stored in association with the information.

  Accordingly, the original data is stored in the operation system file 82 as the data with the name “A”, and the first update data is stored in the update data file 86 as No. 1 and the second update data are stored in the update data file 86 as No. 1 data. 4 data are stored.

  On the other hand, when data reading occurs (NO in step 506, YES in step 550), the read monitoring unit 213 refers to the update log file 84 to determine whether the data to be read exists as update data. (Step 552), if it exists as update data (YES in step 554), the data is read from the update data file 86 (step S556). However, if the data to be read does not exist as update data (NO in step 554), the read monitoring unit 213 reads the data to be read from the operation system file 82 (step 558). Thereafter, when there is an instruction to end (in the case of YES at step 512), the same processing flow as described above is performed. If a process that is neither data writing nor reading is instructed (NO in step 506, NO in step 550), a process corresponding to the instruction is executed (step 560).

  Referring to FIGS. 5 and 6, as an operation mode of terminal device 1, an operation method in a mode in which a plurality of terminal devices 1 (terminal device 1 </ b> A and terminal device 1 </ b> B) and server 600 are connected via communication line 70. explain.
