Description
FIELD OF TECHNOLOGY

The following relates to a method and a system for connecting people in relation to a directory database, said method and system comprising the delivery of a relevant and targeted message according to a particular context.


BACKGROUND

A directory generally comprises organized data and provides a support to search any type of information. For example, the telephone directory, in the paper form or electronic form, allows telephone numbers to be found given the individuals and organizations name, while a web directory provides an organized collection of links to websites in response to search requests.


Advertising directories are also well known. In such directories, advertisements are classified according to some purpose. The most commonly known directory is the hard copy or web form of the Yellow Pages which comprises information about potential providers of goods and services, but advertising directories may be also found in newspapers, regional dailies, weekly papers, technical and professional magazines.


Consumer to consumer, or peer-to-peer, directories are also well known. They facilitate the sale or transfer of goods and services between individuals using a third party providing a website or a paper copy of the offers to match consumers.


Generally, a user consults a hard copy or an electronic directory, of any kind discussed above, to get the information and contact information, for example a telephone number, he is interested in, and contacts the entity, individual, organisation or business, of interest, generally by placing a telephone call to the telephone number of said entity.


One main drawback of this way to proceed is that generally the contact information, i.e. telephone numbers, are the real contact information, i.e. telephone numbers, of the entity to reach, leading to a lack of privacy, especially for unlisted numbers, or silent lines, of individuals posting an advertisement in a peer-to-peer directory. Furthermore, real telephone numbers published in a directory of any kind are generally a target of choice for unwelcome communications, unsolicited communications or unwanted telemarketing calls.


Another main drawback is that the charges of a telephone call to reach an entity, corresponding to a local or long distance call, to a local or national number, or to a pay-per-call or premium-rate telephone number, is generally supported by the person who call, unless the called number is a toll-free or free call number (800, 0800 or 1-800 number), in this case the charges are supported by the called party.


In addition, it is well known that methods and/or systems to connect people usually allow the delivery of advertisements, but generally such advertisements are not automatically activated or delivered. Furthermore such advertisements generally do not match the people's desire or needs, leading to a waste of money for the advertiser, and leading to a bad brand image for the advertiser.
