Abstract

PURPOSE: A variable password scheme changed according to the time and place is provided to remove danger according to information exposure, by changing password uniformly and to use one password in various credit card. CONSTITUTION: A variable password scheme changed according to time and place comprises a variable element and operator. The password is changed by the variable element uniformly in order to prevent an information exposure. The variable element is changed by time and place. The changed variable element according to time is a year, a month, a day, a day of the week and time. The changed variable element according to the place is a country, a province and a city. Also, in the password change, an arithmetic calculation such as addition and subtraction is used.

Description

Variable Encryption System depending upon timing points and geographical points}

Most patents on cryptography are about encrypting / decrypting certain letters or numbers so that others cannot recognize them.

Some cryptosystems allow you to check the time, but this is a check on the system, and you do not use time variables in your cryptosystem.

Even if a password is exposed, the password is constantly changed so that the risk of exposure is eliminated.

In particular, even when used for payment on the Internet, it eliminates the risk of information exposure, which is a disadvantage of the protocol, and removes anxiety about information exposure of users.

Have a password and use it on several cards.

By using arithmetic operators and concatenation operators on variable elements, strings and numbers are added to diversify passwords and make passwords difficult to break.

Encryption selects elements that change over time. Of course, not only the timing but also the place of payment can be used for all variable factors. The elements that change according to time are year, month, day, day of the week, and time.The elements according to the place are divided into country, province, city, and distinction and are based on the place of payment (hereinafter referred to as 'variable element'). Using these elements is not limited to elements that change with time, and has various effects such as increasing variables and preventing crime.

Once these elements are defined, prior to the addition of a constant password (hereinafter referred to as the "constant element") to these elements using arithmetic calculations such as addition or subtraction or more various methods (collectively referred to as "calculation elements"). This is done using the arithmetic calculations mentioned.

To determine the passcode

-Year: y1y2y3y4 (y means 'year', number means digits, e.g. 1999)

-Month: m1m2 (m means 'Month'. Number means digits. Example: 04)

-Day: d1d2 (d means 'day', number means digits, eg 27)

-Hour: h1h2h3h4 (h is a number meaning 'hour', a number means digits, e.g. am07, pm04, 07am, 04pm, 13, 23)

-Day: sun .. sat or 0 .. 6 ('sun' .. 'sat' or '0' .. '6' is an abbreviation or numeric code for 'day of the week')

Itinerary code indicating a place: country code, state, county, county, etc. Phone number code. ZIP code, etc. (eg korea, USA, Australia, 0f49, 012, 02, 0343)

The above code system can be decided at system design time. The password is checked on each system, so it can be different for each system.

An example is demonstrated as follows.

Example number 1 2 3 4

Variable element y1y4 y4m2 weekday y3h1h2h3h4

Arithmetic Elements x 3 +25 +11 +34

Constant addition method. . . .

Constant Element wolf cat12 123 not

Actual Input Password (1) 57wolf 119cat12 svo123 943pmnot

(2) 60wolf 31cat12 057not

In the example above, the position of the variable element and the constant element can be changed and can be configured by using one element multiple times. For example weekday. (h3h4 x 2). m2

Constant passwords can only be configured with numbers, without the English alphabet, as long as the input keyboard can only enter numbers.

Constant addition methods use operators in computer languages. In the example above, '.' Is the 'string concatenation operator' that describes the characters in sequence.

The actual input password is the password that must be entered. The variable elements and descriptions for the above example are as follows:

Example number 1 2 3 4

Variable elements

Actual (1) 1999 1999 April sun + 011 1999 09pm

= 19 * 3 = 94 + 25 = svo = 909 pm + 34

= 909 pm

Variable elements

Actual (2) 2000 2000 Jun 2000 2000

= 20 * 3 = 06 + 25 = 023 + 34 = 057

As shown in the example above, the password changes from time to time and uses arithmetic operations, etc., so even if you know the password, you cannot connect to the system with the same password next time. It is safe to temporarily expose your password on the Internet, and even if you know the password at the place of purchase, the password will change the next time, so you don't have to worry about revealing your password.

Despite the many advantages, there are many surveys showing that Internet commerce is reluctant to use because of concerns about password exposure.

The format of using an address as a variable element is (position code) (arithmetic calculation element) (constant addition method) (constant element), for example 02 * 4. abc1 and the like (02 is a phone number code).

Purchasing on the Internet is expected to increase significantly with the advantage of being universal and cheap. Many Internet users recognize the advantages and want to buy online over the Internet, but due to the possibility of exposing all online data according to the characteristics of the Internet protocol TCP / IP, the exposure of credit card numbers and the Reluctant to buy online due to concerns about abuse.

Also, existing password systems have a fixed password, so if someone knows the password, you have to change it. In banks and other places, employees were asked for their passwords, and in stores, they were inconvenient to enter passwords without fear of exposing them.

According to the present invention, the password is automatically changed according to the point of purchase or the place of purchase, and even if the password is exposed, the same password cannot be used at different time points or other places without knowing the encryption system. Therefore, you do not have to worry about password exposure.

In order to solve this problem of cryptography, hardware methods such as electronic cards have been devised, but since all users have to purchase hardware, it is expensive and wastes resources. The present invention can be simply employed by changing the password system according to the login of the computer system.
