Description

METHOD AND SYSTEM FOR SEARCHING NON-ACQUAINTANCE VIA NETWORK}

The present invention relates to a method and system for finding a person using a communication network.

In general, people come across many different people at places such as subways, bus stops, streets and the like. People who meet by chance like this can include people who like you and people you've met somewhere. However, despite being crushed and likely to have met somewhere, people are unable to talk to each other because of time problems, instant embarrassment, or limitations of memory. In this case, people will not be able to verify the contact's name as well as their name, so it is very unlikely that they will reunite. Moreover, even if you later find out or remember the name, school, etc. of the other party, it is impossible to find the other party without knowing the other party's contact information.

Accordingly, recently, a system for finding a person through a data communication network such as the Internet has been developed to provide a person searching service. The system for finding a person using a conventional communication network receives and stores dictionary information such as a user's name, a home school, a grade / class, a year of graduation, etc. in detail. Here, the dictionary information is information which does not change with time and place. When the user inputs dictionary information such as the name of the other party, the school of origin, the grade / class, and the graduation year, the user connects the user with the counterpart corresponding to the input dictionary information.

However, since the method and system for finding a person using a conventional communication network as described above can retrieve information about the other party only when the user's prior information is input from the user, the prior information is insufficient, such as a person who meets on the street. It is impossible to find a person.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a method and system for finding a person using a communication network that can find a counterpart even if the prior information is insufficient.
