Abstract:
Firstly, a first double exclusion having a weak double exclusion effect and a light exclusion load is performed. Secondly, prior to a second double exclusion having a strong double exclusion effect and a heavy exclusion load, information relating to the result of the first double exclusion is acquired. Then, data objects to be subjected to the second double exclusion are narrowed down according to the acquired information. Lastly, the second double exclusion of only the data objects narrowed down is performed. Thus, an integral double exclusion system having an exclusion load lighter than conventional system while producing a strong double exclusion effect is realized.
