Development of the Device that Restrains Phishing Scams : Experiment for Detection of 2GHz Band Electromagnetic Wave

[出版社版]Phishing scams often occur every day, and it is still not showing signs of decline. The recognized number of criminal damage was about 20,500 and the amount of damage was about 27.6 billion Japanese yen in 2008. This is a very serious problem and a great pressure to the society. To reduce such social anxiety, the device that restrains phishing scams was developed in this study. The most important aim of this study is to detect the existence of the 2 GHz band high frequency electromagnetic wave emitted from a mobile phone. As the result of the production of the device, the expected detection of the electromagnetic wave from a mobile phone could be achieved within the distance of 30 cm at least. Further several improvements, e.g. the improvement in sensitivity of the antenna and so on, will be added to the device in the future
