Bu makalede, yaşadıkları şehrin ve özellikle yaşadıkları ülkenin dışında başka bir yere giden kişilerin, gerçekten
bu yerde olduklarının doğrulanarak istenen kişilere bildirim yapılabilmesi için bir cihaz ve bu cihaza dayalı
yöntemler önerilmektedir. Önerilen cihaz, kayıtlı sabit noktalara yerleştirilir ve kişisel mobil aygıtlar ile yalnızca
kısa mesafe kablosuz ağda haberleşir. İnsanların, mobil aygıtlarını çoğu zaman, seyahate çıktıklarındaysa hemen
her zaman, yanlarında bulundurdukları varsayımıyla, bir mobil aygıtın konumu bilinen sabit bir cihazın
yakınında olduğunun doğrulanması, o aygıta sahip kişinin de o kayıtlı konumda olduğu anlamına gelmektedir.
Kısa mesafe kablosuz ağ iletişiminde kullanılan verilerin açık anahtarlı kriptografi (AAK) ile şifrelenmesiyle, o
yerel ağda bulunulduğu ispatlanabilir hale getirilmekte ve böylece ilgili kişinin belli bir zaman için belli bir
konumda olup olmadığının doğrulanması mümkün kılınmaktadır.

Notification of Verified Locations using Short-Range Wireless Communication and Public-Key Cryptography

Öz

In this paper, we propose a device and methods, based on this device, in order to create notifications about
verified locations of people to other people in their contact lists, when they arrive in another city, and in
particular, in another country other than homeland. The proposed device is stationary at a known and recorded
location, and it communicates with personal mobile devices only in short-range wireless network. With the
assumption that a personal mobile device is with its owner most of the time, and almost always during a trip,
verification that the mobile device is in the vicinity of a stationary device means that its owner is also in that
certain location. Using public-key cryptography in encryption of data in the short-range wireless communication,
it becomes provable to be in that local network, and hence it is possible to verify, whether a particular person
was at a particular location in a particular time.
