While it brings convenience to daily life, but too much relying on it may potentially cause serious issue in certain scenario. µ¿¾È ÀÏ»ó »ýȰ¿¡ ÆíÀǸ¦ °¡Á®ÇÏÁö¸¸ ³Ê¹« ¸¹ÀÌ ÀÇÁ¸¿¡ ÀáÀçÀûÀ¸·Î ƯÁ¤ ½Ã³ª¸®¿À¿¡ ½É°¢ÇÑ ¹®Á¦°¡ ¹ß»ýÇÒ ¼öÀÖ½À´Ï´Ù. Just recently, a team of researchers from Cornell University have demonstrated a way on how to fool the GPS units by sending out false signal that imitate actual satellite signal patterns. ´ÜÁö ÃÖ±Ù¿¡, ÄÚ³Ú ´ëÇп¡¼ ¿¬±¸¿øÀÇ ÆÀ À§¼º ½ÅÈ£ ÆÐÅÏÀ» ¸ð¹æÇÏ´Â ¹æ¹ýÀ» ½ÇÁ¦ÀûÀ¸·Î À߸øµÈ ½ÅÈ£¸¦ º¸³»´Â ¹Ùº¸´Â GPS À¯´Ö¿¡ ´ëÇÑ ¹æ¹ýÀ» Áõ¸íÇϰíÀÖ´Ù. Those signals will be interpreted by the GPS receivers as a genuine signal which causes the wrong position information being retrieved by end users. ±× ½ÅÈ£´Â À߸øµÈ À§Ä¡ Á¤º¸¸¦ ÃÖÁ¾ »ç¿ëÀÚ¿¡ ÀÇÇØ °Ë»öµÈµÇ´Â ÁøÁ¤ÇÑ ¿øÀÎÀº GPS ¼ö½Å±â¿¡ ÀÇÇÑ ½ÅÈ£·Î ÇØ¼®µÉ °ÍÀÌ´Ù. For normal consumers, it may be still alright but the consequence could be very serious especially when such a scenario happens in military applications.

GPS receiver is capable to lock to at least four satellites orbiting around the earth to obtain accurate positioning information through specific pattern signals.

Although existing transmitter is quite large in size, about the size of a suitcase, but it is foresee that the size can be shrunk down as small as a cigarette pack, making the proximity attack possible anywhere without the users¡¯ acknowledgment. ±âÁ¸ÀÇ Æ®·£½º ¹ÌÅÍ´Â »ó´çÈ÷ Å©±â¿¡, °¡¹æÀÇ Å©±â¿¡ ´ëÇØ Å«ÀÌÁö¸¸, ±× Å©±â·Î »ç¿ëÀÚ°¡ '¸¦ ÀÎÁ¤ÇÑ ´ã¹è ÆÑÀ»·Î, ±ÙÁ¢ °ø°ÝÀ» °¡´ÉÇÏ°Ô ÀÛÀº ¾Æ¹«µ¥µµ¾øÀÌ ÁÙ¾îµé ¼ö ¿¹°ßÇÑ´Ù.
