Description

Password input system in internet and method for inputting password

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a password input system on the Internet and an input method thereof, and in particular, a password input system on the Internet for inputting a password without using keyboard input using a graphics interface, and a key value corresponding to a portion of the screen. It relates to an input method for generating an encryption key by pluralizing them.

The Internet is the world's largest network, interconnected with telecommunication networks in more than 190 countries around the world, and is connected by the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol.

The Internet is a very widespread and general purpose network with 200 million users and about 30 million hosts connected to the Internet.

Such an Internet is called the sea of information, and it is growing so that many people can easily and conveniently obtain various kinds of information and contents. In addition, the Internet can search for multimedia information, enjoy real-time Internet broadcasting, and access to computers around the world. In addition, the usefulness of the Internet makes it easier to find what you can't do on the Internet, rather than knowing what you can do, such as e-commerce, e-mail, real-time conversations, online games, Internet phones, file transfers, counseling, and so on. Awesome.

In such an Internet-based web site, a user authentication system is used to specialize users and to give preferences or manage the number of users statistically.

Such a user authentication system individually assigns a user name (hereinafter referred to as an 'identification') and a password to a person who accesses an Internet site, thereby providing a user's personal information and contact information. In general, using the material commercially or giving special benefits to its members. Here, the ID indicates that the person is authorized to use the system, and the ID is confirmed by the password.

In addition, such a user authentication system enables data communication between multiple computer systems that control a large amount of data, allowing different users to easily access their computer system resources.

The password input system on the Internet according to the prior art is to log in to the host computer from the client side computer in order to solve the security problem of the general network computer system as shown in FIG. This prevents unauthorized access to the system.

At this time, the user accesses the Internet initial access document stored in the host computer using the client computer, and enters the ID and password into the input fields 2 and 3 on the document screen 1.

For example, when a user inputs an ID such as "ABC12" of a predetermined number or letter combination and a predetermined password through the keyboard, "ABC12" is displayed in the ID field 2, and the password field 3 ) Is displayed as "******".

In addition, in order to prevent illegal information leakage or data tampering that may occur during the transmission of data on the Internet, some password input systems on the Internet may use "SSL" (a protocol used for secure transactions over a network by Netscape). It uses encryption technology such as Security Socket Layer. Even in this case, the input method of inputting an ID and password is input using a keyboard.

However, the password input system on the Internet according to the prior art requires expensive programs in order to use the encrypted technology, and there are difficulties in use and economic problems such as requiring separate authentication for each host server.

In addition, the conventional password input system is easy to be exposed to the person next to the password when entering a combination of numbers or letters, there is a disadvantage that it is easy to duplicate and leak by observing the communication line.

In addition, the conventional password input system in most multimedia (picture, text, sound, video, etc.) environment, such as Internet sites to search for information using a mouse, so you need to alternate between keyboard and mouse to enter a password There is discomfort.

Also, document files on the Internet have both pictures and text. In addition, a picture input window having a plurality of numeric pads and input buttons such as a telephone dial pad is used in some cases.

However, these number pads are simply used as a means of entering numeric information into the system without using a keyboard, and not as a means of entering passwords. The reason is that passwords can be stolen very easily if the person next to you sees clicking the number pads.

Therefore, the present invention has been made to solve the problems of the prior art as described above, by clicking the sectors and country or city name of the displayed clock on the screen, to prevent the leakage and exposure of passwords when using the graphics interface, The purpose is to provide a password input system on the Internet that can maximize the convenience of.

Another object of the present invention is to provide an input method of a password input system on the Internet that selects and encrypts a plurality of key values through a graphics interface.

First, as shown in FIG. 2, the password input system on the Internet of the present invention connects the client computer 100 and the host computer 200 to the Internet, and moves a mouse to a predetermined portion of the input picture displayed on the screen 160. Click to enter the password.

Such a client computer 100 uses a conventional web browser program 150, and when the web browser program 150 accesses the initial document of the host computer 200, the encryption program 110 is automatically downloaded. .

The encryption program 110 is composed of a picture input unit 120, a key map 130 (key map) and the condenser 140.

Here, the picture input device 120 divides the password input picture (for example, a world clock picture, an advertisement, etc.) on the screen 130 into tracks and sectors, and each sector thus divided. When is clicked with a mouse, coordinate values corresponding to the sector are input. This coordinate value is changed to the key value of the preset keymap 130. The multiplier 140 outputs other key values around the key value based on the key value generated on the key map 130. The generated key values are converted to an encrypted key by an "International Data Encryption Standard" (IDEA) encryption algorithm that performs document transmission and reception on a conventional Internet.

In addition, the host computer 200 is a general UNIX or NT server based on "HyperText Transfer Protocol (HTTP)", and decrypts an encryption key again in a "computer graphics interface" or "JAVA" language. And a decoder 230, a key management program 220, and an information meta 240.

In the present invention, the decoder 230 is implemented by a conventional decryption algorithm that returns the aforementioned encryption key back to the original key value.

The key management program 220 stores the decrypted key values and IDs, and compares the stored key values and IDs with the key values and IDs to be input according to a request to log in from the client computer 100 to log in. It can be approved or rejected.

In addition, the information meta 240 measures the amount of information coming into the host computer 200, and when abnormal excessive information is input from the client computer 100, a screen that can express the amount of information relatively to the client computer 100 is displayed. Display and send various prompts, such as a message to wait for login access. The information metadata 240 serves to prevent abnormal information (hacking program, data bomb) from being input to the host computer 200, prevents overload of the host computer 200, and uses the client computer 100. It does not have a hasty state of mind to the user.

As illustrated in FIG. 3, the password input system on the Internet as described above displays the screen 160 using the graphics interface on the client computer 100.

For example, on the screen 160, a password input picture is formed into a plurality of clock pictures 170 and 171 so that a trade password or netizens can input a password while checking the world time.

These clock figures 170 and 171 basically display the dynamic time of each of the six countries or countries provided from the above-described host computer, respectively, and additionally a plurality of countries and countries using the drop menu 180. You can see their perspective. Also, on the screen 160, a new / change button 181 and an input field 182 for entering an ID are formed.

The new / change button 181 is an operation button that is clicked by the user so that the initial ID input box appears on the screen. The user may input the ID in the initial ID input box, and input the password by clicking a predetermined position of the clock figures 170 and 171 on the screen 160 with the arrow 183 of the mouse.

The banner billboards 178 and 178a are arranged at the center of the clock pictures 170 and 171 to alternately advertise at minute intervals.

As shown in an enlarged view in FIG. 4, a drop menu 180 and a clock picture 170 for selecting a country and a city are shown on the screen, and in particular, the hour hand 172 and the minute hand 173 are shown in the clock picture 170. The second hand 174 displays a time corresponding to the country or city selected in the drop menu 180.

In addition, the clock picture 170 is divided into four tracks 176, as shown by the ring-shaped line indicated by a dotted line, and the outer track is divided into 24 sectors 177 and 177a, and the innermost track is It is divided into 60 sectors 177b.

In addition, numbers 1 to 24 are written on the outside of the circular rim 175, and numbers 1 to 60 are written on the innermost track divided by 60 sectors 177b. Here, the numbers 1 to 24 simply display the numbers 1 to 24 to help the user associate with his or her password, and the numbers 1 to 60 represent the 60 second intervals through which the second hand passes.

In addition, in the present invention, in order to make a simple password, it is possible to be divided into larger parts.

Such a clock plot 170 produces a ticking sound as the cuckoo 179 protrudes on the screen by the "JAVA" language each time the sectors 177, 177a, 177b are clicked in sequence with the arrow 183 of the mouse. In addition, the circular rim 175, the hour hand 172, the minute hand 173, and the second hand 174 may each additionally flicker, change color, or change in size.

The country and city of the drop menu 180 refer to the first key value of the first digit of the password, and the sectors 177 with numbers written outside of the circular border 175 are the second key value of the second digit of the password. Means. In addition, the sectors 177a and 177b formed inside the circular edge 175 mean third, fourth, and fifth key values, which are the remaining digits of the password. That is, while viewing the clock picture 170, the user can memorize the password by memorizing the country or city name and selecting the respective sectors 177, 177a, and 177b while associating hours, minutes, and seconds.

In more detail, the user selects a country or city by pressing an arrow button of the drop menu 180 using a mouse to set a password. At this time, the hour hand 172, the minute hand 173, and the second hand 174 of the clock figure 170 move according to the time of the country or city, so that the time of the selected country or city can be known. First key values corresponding to the selected country or city are input to the picture input unit described above. That is, the user does not memorize the first key values of the password, but rather memorizes the country or city name that becomes the first key value of the password. Such a country or city name is a country or city name of a country of which the user is most interested, and the user can enter a password while checking the time of the country or city.

In addition, when the user clicks on any one of the sectors 177 having numbers 1 to 24 by using the arrow 183 of the mouse, the border of the circular border 175 is flickering or cuckoo 179. Open the door, protrude and enter again. In the same manner, when the user clicks on the plurality of sectors 177a and 177b arranged inwardly of the circular border 175, the hour hand 172, the minute hand 173, and the second hand 174 blink, and the cuckoo ( 179 opens the door, protrudes and enters again. This shows that the user's click has been normally performed, and the user can naturally memorize the positions of the sectors 177a and 177b which are the same as the input position of the password, reminiscent of the time of the clock. In addition, since the other clock pictures configured in the same manner as the clock picture 170 described above are represented in plural on the screen as shown in FIG. 3, the user may make the password more complicated and difficult.

The coordinate values of the sectors 177, 177a, and 177b are changed into second, third, fourth, and fifth key values by the picture input unit and the multiplier described below.

In addition, as shown in FIG. 5, the picture input unit uses a mouse arrow 183 to click on a predetermined portion of a sector 177 to obtain a coordinate value (x _o ˜) within the boundary line of the sector 177. x _n, y _{n o} ~y key value (a _o ~A _n, B _o ~B _n) on the keymap 130 corresponding to the sector 177 in the keymap 130 is determined, and predetermined to be one of) One of the key values 131 is selected. In this case, the multiplier selects a plurality of key values 132 arranged around the selected one key value 131. The plurality of key values 132 are output as the second key value of the password. In the same way, the third, fourth and fifth key values of the password are output from the multiplier.

In addition, the multiplier capable of generating a plurality of key values in this manner may variously output different types of key values according to the nature of the selection algorithm. The second to fifth key values thus output are combined with the aforementioned first key value and arranged in a string of passwords.

And, as shown in Figure 6, through the clock picture (170, 171), when the login access to the host computer, the information metadata of the host computer is displayed on the screen 160 of the client computer information screen ( Send a "HTML" document that can display 161).

At this time, a circular meta group 162 is represented on the information meta screen 161, and the meta group 162 has a different color (green, yellow, red) in an unsafe information area 162a and an appropriate information area ( 162b) and the overload information area 162c are divided, and the needle 163 which displays the information amount is rotated in the circumferential direction a. This meta device 162 is displayed with a variety of instructions 164 that the user can recognize.

In the following, the input method and operation relationship of the password input system on the Internet as described above will be described.

A user who accesses the password input system on the Internet of the present invention accesses an initial access document. Such a user presses the New / Change button so that the initial ID input box appears on the screen, and performs a procedure of typing and entering an ID in the ID registration box (S10). In operation S20, the user selects a country or a city from drop menus by using a mouse to input a password. At this time, the plurality of clock pictures display the time of the corresponding country or city, respectively (S30). In addition, the user moves the mouse arrow outside the circular border of the clock figure to click on any of the sectors where the numbers are represented, then click on the sectors inside the circular border that can in turn change the shape of the hour, minute and second hands. (S40). The coordinate values of the clicked sectors are input to the picture input unit (S50). The input coordinate values are converted into key values on the keymap by the picture input unit, and are multiplexed into a plurality of key values according to the characteristics of the algorithm by the multiplier. The pluralized key values are arrayed to form a password consisting of a string (S60). Then, the encryption program having the "IDEA" encryption algorithm generates an encryption key corresponding to the password consisting of a plurality of strings (S70). The generated encryption key and the above-mentioned ID are sent to a host computer connected to the Internet by a web browser (S80). The information meta data of the host computer measures the amount of information of the transmitted encryption key and ID, and displays a screen on which the client computer can express the amount of information relatively (S90). In addition, when the operation is normally performed in the information metadata, the host computer stores the transferred ID and the encryption key (S90).

The decoder of the host computer changes the encryption key to a password and inputs it to the key management program together with the ID. At this time, the key management program stores IDs and passwords for a plurality of users in a format such as "ID: password". The key management program compares the ID and password input from the client computer with the stored ID and password, and permits or prohibits the login.

As described in detail above, the password input system and input method on the Internet of the present invention constitute a password by a method of pluralizing a key value corresponding to a selected sector on the screen, and change the configured password to an encryption key so that the password is transmitted on the Internet. This has the advantage of preventing password leakage and leakage.

In addition, since the password input system on the Internet of the present invention can enter a password by clicking a predetermined part on the screen with a mouse, the person next to it can not easily memorize, it is duplicated and leaked by a method of observing the communication line There is a difficult advantage.

In addition, the password input system on the Internet of the present invention has the advantage of maximizing user convenience by inputting a password using a mouse.

In addition, the password input system on the Internet of the present invention has the additional advantage of checking the world's time while entering the password.

Although the technical idea of the password input system on the Internet of the present invention has been described above with the accompanying drawings, this is intended to illustrate the best embodiments of the present invention by way of example and not limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
