Claim:
A method for blocking objectionable information on a mobile communication terminal, the method comprising: receiving objectionable information determination data from a server and storing the objectionable information determination data in the mobile communication terminal if a current version of the objectionable information determination data is not stored in the mobile communication terminal; receiving objectionable information determining software from the server and installing the objectionable information determining software in the mobile communication terminal if the current version of the objectionable information determining software is not installed in the mobile communication terminal; receiving header information corresponding to a particular multimedia content; extracting grade information from the header; determining if the extracted grade information is an allowable grade indicating that the particular multimedia content can be received by the mobile communication terminal; receiving the particular multimedia content if the determining step determines the extracted grade information is the allowable grade or if the grade information is not recorded in the header; comparing the received multimedia content using the objectionable information determining software with the objectionable information determination data stored in the mobile communication terminal to determine if the multimedia content is objectionable; assigning an objectionable grade to the header of the multimedia content when the comparing step determines the received multimedia content is objectionable; and transmitting the header including the assigned objectionable grade including a priority of the assigned objectionable grade to the server that sent the particular multimedia contents so that the server adjusts the grade for the particular multimedia content, if the priority of the assigned objectionable grade is higher than a priority of a previously assigned objectionable grade.
