PURPOSE: A method for blocking an area invasion between web server account users is provided to prevent a predetermined area user having an endowed usage right with an account as a "nobody" from invading not endowed area and a web program although the user logs-in a web server. CONSTITUTION: As an area invasion blocking method between web server account users, a web server software receives information with respect to a predetermined area and file wanted by a user for an access from a user(S16). The web server software judges whether the file exists in the area(S18). If the file exists in the area wanted by a user for an access, the web server software transmits an access approval request and a pre-set cipher text to a kernel(S20). It is judged whether the approval request is normal or not using the cipher text received from the web server software(S22). As a decision result of the kernel, if the approval request is normal, the kernel makes the web server software access to the predetermined area wanted by the user(S23). The web server software transmits a command processing result to the user, and the user requests a restoration of a user right to the kernel(S28). The kernel restores the user right(S30).
