INTRODUCTION

A telephone directory is a collection of telephone numbersand associated customer details. However, unlike a standardtelephone directory, where the user uses customer's details(such as name and address) in order to retrieve the telephonnumber of that person or business, a telephone directoryallows users to search by a telephone service number in ordto retrieve the customer details for that service.Telephone directories are used by law enforcement and othemergency services in order to determine the origin of anyrequest for assistance, however these systems include both publicly accessible (listed) and private (unlisted) services. Asuch, these directories are restricted to internal use only.

Publicly accessible reverse telephone directories may be provided as part of the standard directory services from thetelecommunications carrier in some countries. In other countries these directories are often created by phone phreakers by collecting the information available via the publiclyaccessible directories and then providing a search functionwhich allows users to search by the telephone service detail

Advantages and disadvantages of using telephone directory

Advantages:-

A telephone directory usually is used so that people can find all of the contact number in their area, usually in thcity or their locality. The idea is that anybody can easily access thatinformation and use it any time, whenever they really want. Now thgood and bad at the same time, because you can only find the numbthat you need in your locality. If you are looking for a business thatout of town, you cant find it in the local telephone directory.

Disadvantages:-

The main problem of info gathering methods sucas free telephone directory is that such methods are often abused,which causes people to be bothered about their privacy and leakage
