Abstract: Emails are received and the received emails are classified and accumulated based on relay path information contained in the header of each email. For each of the classified groups, a judgment is made according to a judgment rule including at least (1) the number of received emails per unit time is a first threshold or more and (2) the number of emails having an invalid destination address is a second threshold or more. For emails included in a classified group satisfying at least a prescribed number of items of the judgment rule, a mail process including (a) blockage of delivery to the user and (b) transmitting a pseudo error message replicating an undelivery mail to the source is carried out.

Abstract: A computer-executable browser program, which generates drawing data for displaying contents on a display in accordance with contents data described in markup language, is provided with plurality of browser modules in which different functions are implemented, and a browser module managing unit that manages the plurality of the browser modules. One of a plurality of the browser modules is a rendering module to carry out rendering contents data for generating drawing data. At least one of a plurality of the browser modules is such a module as exclusively used for substituting for or changing a part of a rendering module or adding a separate function to functions of the rendering module. The browser module managing unit determines to process an element included in the contents data by using any of the exclusive modules in accordance with a predetermined condition so as to provide what makes a rendering module process such a thing that a predetermined change is added to the contents data.

Abstract: A moving image generation method includes: a content designation step of designating a plurality of contents used for a moving image; a content collecting step of collecting each designated content; a content image generation step of generating content images based on the collected contents; a display mode setting step of setting a display mode of each generated content image; and a moving image generation step of generating a moving image where each content image alters with respect to time in accordance with the display mode which has been set.

Abstract: A moving image processing method includes: an operation item setting step of setting operation items to be operated on the moving image; a time interval setting step of setting which time interval in a reproducing period of the moving image should be defined as an interval in which the operation items that have been set are executable; a display area setting step of setting display areas for images for operations corresponding to the operation items that have been set; an image combining step of combining the images for operations corresponding to the operation items that have been set with the respective frame images, in accordance with the time interval setting step and the display area setting step; and an associating step of associating, with each combined frame image, information concerning the display areas of the images for operations in the frame image and information concerning the operation items, and storing each combined frame image and the associated information.
