It appeared with the development of IT skills to help the social network SNS(Social Network Service) on the online form. Many people around the world and in the business environment changes is the emergence of social networks are bringing. And the rapid development of the idea, but are insignificant for the security threats that are used by many people in many companies, and social network services. In addition, although it is true that this connection is increased from the number of mobile machines to the development of M2M, that is not recognized for that vulnerability. To evaluate and identify vulnerabilities against security threats and countermeasures for the SNS access the social network on the M2M After looking for privacy and in the present.

-In this paper, we have checked a method of performance evaluation for electronic pedal, which is a core technology of HBD for detecting the axle temperature of high-speed train. As it is practically impossible to conduct train speed test of 500 km/h, we utilize a high speed rotor for evaluating high speed performance of the electronic pedal instead. According to this method, we found that the measurement results by the velocity measuring instrument is similar with the ones from this research through the high speed rotor. In conclusion, it will be possible to conduct reliability evaluation for high speed performance for Beacon, Balise and RFID, which are utilized for transmitting vital information of train control systems through using the rotor.

The development of communication method for a variety of intelligent automobiles are delivering comfortable and safe information. However the development of such communication method must also think about security. Even the update of navigation to be used for intelligent automobiles uses the wireless updating methods but the updating methods currently being used has no reliable security measures. The navigation communications used in the intelligent automobiles are being provided with TTI(Traffic and Travel Information) service using a variety of methods by the countries. In the case of Korea, most are based on T-DMB using the TPEG method for transmitting the information. By identifying
