You don't need any special software. In Windows Explorer, select all the files, right click>properties. Click Details tab, and you can directly batch-edit certain EXIF fields. I know Author is one of the editable fields, and I'm assuming that's what you mean since I can't seem to find "Owner's Name" in my CS3 file properties dialogue. When I set my camera's Owners Name from EOS utility, my name shows up in my images' Author field, so I'm pretty sure that's what'll work.
