System and method for detecting computer viruses in a mobile communication system

摘要

It is an object of the present invention to allow efficient detection of computer viruses in a portable telephone. The server device (10) comprises a pattern data transmission request receiving unit (12) which receives pattern data transmission requests that include information of the portable telephone (100), a pattern data extraction unit (13) which extracts specified pattern data from a plurality of sets of pattern data on the basis of the information of the portable telephone (100) contained in the pattern data transmission requests received by the pattern data transmission request receiving unit (12), and a pattern data transmitting unit (14) which transmits the specified pattern data extracted by the pattern data extraction unit (13) to the portable telephone (100). <IMAGE>
