System and method for filtering message
First Claim
1. A method of filtering messages, comprising the steps of:
- (a) generating a conversion target letter table storing hex code information corresponding to each conversion target letter that may be used for eluding filtering and conversion letters corresponding to each of the conversion target letters;
(b) comparing a hex code of a letter of a message text inputted by a user with the hex code information stored in the conversion target letter table;
(c) when the hex code matches any one of the hex code information stored in the conversion target letter table, converting the letter to the corresponding conversion letter stored in the conversion target letter table;
(d) repeating the steps (b) and (c) for all of letters of the message text so as to create a converted message text; and
(e) when a pre-configured prohibited word or words are included in the converted message text, filtering the converted message text.

Abstract
A system and method for message filtering are disclosed. A conversion target letter table is generated which stores information on letters that may be used to elude filtering, the table storing the hex code information of each letter that may be used for eluding filtering and the conversion letter information regarding the conversion letter to which each letter is to be converted. A hex code of a message text inputted by a user is compared with the hex codes of the table, and when a conversion target letter is included, it is converted to the conversion letter stored in the conversion target table associated with the letter. When the conversion is completed, it is determined whether or not pre-configured prohibited words are included in the converted message; and message filtering is performed.
