the web browser. This requires the transfer of data files and the formatting of a table
on the web browser." (Id. at 2.)
Small files (e.g., "character values") may be passed directly from the database,
converted into a hypertext markup language ("HTML") format, and displayed on the
browser. Large object binary files ("LOBs") (e.g., picture files, video files, audio files,
executable code), however, are difficult to pass directly. Accordingly, LOBs are often
stored in a temporary directory, and a datalink is passed to a requesting browser. (Id. at
3-4.) "Given the volume of potential Internet use and the size of LOBs, a temporary
directory may rapidly fill up even relatively large memory devices," (id. at 4.), explains
the appellant. "Full temporary directories would no longer be accessible and would
prevent the retrieval and use of additional LOBs. Furthermore, because the temporary
directory is a public directory, a hacker may be able to access LOBs in the temporary
directory, which are stored in the temporary directory beyond a reasonable time." (Id.)
Accordingly, the appellant's invention monitors the time that a LOB has been
stored in a temporary, public directory. More specifically, an interface module stores
data files requested by a web browser in the directory. The interface module generates
or duplicates data file names corresponding to each file and sends the names to a clean
module. A timing module generates time stamps for each name; the time stamps reflect
