Abstract

The technical field to which the present invention belongs is the field of electronic mail retrieval. An object of the present invention is to provide a method of searching using an existing telephone number in an e-mail search. The step of the present invention is carried out in three steps as follows.

Step 1: When the user sends the phone number and name by e-mail, build a database consisting of the phone number field and the e-mail address field.

Step 2: The search system receives the landline and mobile phone numbers associated with the e-mail address from the user and compares them with the phone number field in the database.

Step 3: When comparing, display the value of the email address field of the matching record on the screen to inform the email address.

This is a very useful solution to privacy concerns that arise when searching by name.

Description

{The e-mail searching method by telephone number.}

The technical field to which the present invention belongs is the field of e-mail retrieval.

In the conventional field of e-mail searching, there is a method of informing a person's e-mail address using a name as a search word.

In order to operate a conventional e-mail retrieval system, a user must register in advance. However, when registering in the conventional e-mail retrieval system as a personal name as a search word, this method has a privacy problem.

The present invention is a method for requesting minimum information of a user and requesting the information limited to a telephone number.

The operation of the search system is almost the same. In other words, it enters the data to be searched for and displays matching or similar contents on the screen. In the present invention, the design process of the e-mail retrieval system goes through the following steps.

Step 1: When the user sends the phone number and name by e-mail, build a database consisting of the phone number field and the e-mail address field.

Step 2: The search system receives the landline and mobile phone numbers associated with the e-mail address from the user and compares them with the phone number field in the database.

Step 3: When comparing, display the value of the email address field of the matching record on the screen to inform the email address. If there is no matching record, it outputs no matching data and prompts the user again. The following describes each step in detail.

Step 1: Build a Mail Database

To perform a search, a database must be in place. Data to be built in the database can be performed on data registered by the user. This is because when an administrator registers arbitrarily, it can be a violation of privacy.

In the present invention, registration uses e-mail. However, you can also think about how to register to apply online. However, the online course should complement the verification process later. When you register, write and send the landline or mobile number, or both, to your e-mail address to find your e-mail address. The contents of the homepage of the search engine corresponding to the registration process are as follows. However, it is assumed that the email address of the system receiving the registration is test@test.co.kr.

<a href="mailto:test@test.com"> Register </a>

Receive the e-mail sent by the user and build a database based on the contents. For example, if the landline phone is 0652-275-0000 and the e-mail address is testuser@test.co.kr, the database construction is implemented as follows.

"Phone number field" "e-mail address"

06522750000 testuser@test.co.kr

The database is divided into a telephone number field and an e-mail address, as shown above. The size of the telephone number field is 32 bits, and the e-mail address is not restricted.

The same is true if only the mobile number is registered. For example, suppose the mobile phone number is 014-000-0000 and the e-mail address is testuser3@test.co.kr.

"Phone number field" "e-mail address"

0140000000 testuser3@test.co.kr

The same is true if you register more than one. For example, suppose the telephone numbers are 0652-275-0001 and 014-000-0001, and the e-mail address is testuser5@test.co.kr. The database is configured as follows.

"Phone number field" "e-mail address"

06522750001 testuser5@test.co.kr

0140000001 testuser5@test.co.kr

This telephone numbering system can be registered by foreign users. For example, suppose someone in the United States has a phone number of 123-456-7890 and an e-mail is testuser@test.com.

"Phone number field" "e-mail address"

0011234567890 testuser@test.com

In the value of the telephone number field 0011234567890, '00' exists to distinguish it from the area code, and then '1' means the country code of the United States. Of course, the remaining 1234567890 is the area code, including the area code.

Step 2: User Input and Comparison

There is a way to use the <Form> tag as a way of receiving input from the user and passing it to the server. The following is an example used in the present invention.

<Form method = "POST" action = scripts / ss.pl>

Enter number to search for: <input name = "number" type = "TEXT" size = "30,1">

<input type = "SUBMIT" value = "Search">

In the above statement, the method in the <Form> tag is the way to send to the server, and the action is to specify the program to be executed. The name of the <input> tag is used to specify a variable to receive the value entered by the user. The type of the <input> tag is submit, which acts as a user interface for executing the action of this Form statement.

The value entered by the user may include a space or the '-' sign of 0652-270-0000. Of course, it can be just a number, not included. However, all number fields in the database are numeric. Therefore, the process of deleting a space or '-' character should be performed first. This process uses the Perl language in the present invention. The following is a part of our program.

sub del_string {

local ($ str); // variable used for user input data

local ($ delchar); // variable to determine which character to delete

local ($ c_length); // Variable that determines the length of the input data

local ($ output); // variable used for data returned after processing

local ($ c); // local variable

local ($ comp); // local variable

$ str = $ _ [0]; // of the function that saw the argument in the calling function

// convert to variable

$ delchar = $ _ [1]; // take the value to be deleted as an argument

// convert for use in this function

$ c_length = length ($ str); // assign length to variable

$ output = ""; // initialize the variable to be used for the return

for ($ c = O; $ c <$ c_length; $ c ++) // Handle To The Entered String

{

$ comp = substr ($ str, $ c, 1); // one of the strings entered

// accept character

if ($ comp ne $ delchar) // Check if the character should be deleted

{

$ output = $ output. $ comp; // should not be deleted

// assign only characters to be assigned to variables

}

}

$ output; // variable back to the calling function

}

In this way, the value entered by the user is compared with the telephone number field of the database previously constructed and returns the value of the e-mail address field. For example, if the inputted data is 0652-270-0000, it is first compared with the telephone number field of the database already constructed using 06522700000 as a search word with blanks and '-' characters removed. Comparison can be done by searching the records one by one from the beginning of the record and binary searching by comparing with the median. In the present invention, since the test environment, a sequential search method was used. The important part of this method is described in Perl language.

open HAND, "data.db"; // The file used as database is data.db

// HAND is used as the file handle.

end: // mark the exit as it exits the loop

while (3> 0) {// Set the loop to continue.

read HAND, $ all_string, 200; // Read data from file.

$ one_line = index ($ all_string, "＼n"); // to distinguish records

// Return the length of the first record.

$ comp_name = substr ($ all_string, 0,32); // in the record

// phone number field extraction

$ comp_name = & del_string ($ comp_name, $ del);

// remove spaces from the extracted phone number field

if ($ m_name eq $ comp_name) // compare with user input

{

$ flag_x = 1; // Use the variable $ flag_x as an indication when they are equal.

$ out = substr ($ all_string, 32, $ one_line-32);

// equal to the value entered by the user

// Assign the value of the email address field to the variable $ out.

last end; // exit the loop

}

$ one _- line ++; // to indicate the location of the next record

$ one_line ++; // Specify record length including control characters.

$ charcount + = $ one_line; // position the next record in the file

// Determine the size to move forward to specify.

seek HAND, $ charcount, 0; // advance to next record position.

if (eof HAND) // check if end of file

{

last end; // break out of loop

}

}

For example, if the value entered in such a program is 06522700000, testuser@test.co.kr is returned in $ out in the above program, preparing an address for writing an e-mail.

Step 3: print the search results on the screen

If the data obtained in step 2 is identical, the value of the variable $ flag_x becomes "1". Therefore, you can print out the search results on the screen under this condition. If we implement this method using Perl language,

if ($ flag_x> O) // of user built data and built database

{// Condition when phone number field value match.

print "Content-Type: text / html＼n＼n";

// header section for text sentence output

print "<br> for the $ m-name you entered";

// $ m-name is a variable that remembers the number entered by the user.

print "email address is";

print '<a href="mailto:$out"> $ out';

// $ out is the email address in the database.

}

If there is no match, it prints the message "There is no matching data" and prints a form that can be input from the user. If this is implemented in Perl language, it is as follows.

print "Content-Type: text / html＼n＼n";

// header section for text sentence output

print '<center> <font color = "red">';

print "There is no match. Please try again.";

print "</ font> <br>";

print '<form method = "POST" action = scripts / ss.pl>';

print "Enter the number to search for:";

print '<input name = "number" type = "TEXT" size = "30,1">';

print '<input type = "SUBMIT" value = "search">';

print "</ center>";

According to the present invention can solve the privacy problem that appears when the name as a search word. That is, the present invention only remembers the user's telephone number and can know the e-mail address.
