## Title
System and method for authenticating an end user

## Abstract

A method for authenticating an end user. The method begins by generating a login field in response to receiving an authentication request from an end user. The login field comprises a plurality of colored nodes containing a first subset of nodes matching both color and location to a second subset of nodes residing in a transparent credit card being controlled by the end user. Next the method determines the authenticity status of the end user by comparing data received from the end user with the first subset of nodes. The end user having generated the data by overlaying the transparent credit card on top of the login field and selecting at least one colored node. Each node being selected according to a function utilizing both static and dynamic variables. Finally, the method sends the determined authenticity status to the end user via an output device.

## Background
BACKGROUND OF THE INVENTION
The present invention relates to authenticating an end user; more specifically, authenticating an end user by means of dynamic information to prevent fraud.
Conventional authentication methods utilize static information to validate an end user. Since static information by its very nature rarely changes, individuals can easily capture an end user's authentication information for fraudulent use in the future.
Furthermore, conventional authentication methods traditionally employ only 1-way authentication. The term 1-way authentication hereinafter means identifying only a single party to a multiple party transaction. Conventional authentication methods usually call for an end user to authenticate to an entity (e.g. bank, credit card company, government agency, etc.) without the entity authenticating to the end user. The use of 1-way authentication methods exposes an end user to phishing attacks. The term phishing hereinafter means an attempt to criminally and/or fraudulently acquire sensitive information by masquerading as a trustworthy entity in an electronic medium.
SUMMARY OF THE INVENTION
The present invention provides a method for authenticating an end user, said method comprising:
generating a login field in response to receiving an authentication request from said end user, said login field comprising a plurality of colored nodes, said plurality of colored nodes containing a first subset of nodes matching both color and location to a second subset of nodes residing in a transparent credit card being controlled by said end user;
determining an authenticity status of said end user by comparing a third subset of nodes received from said end user with said first subset of nodes, said third subset of nodes being received in response to sending said login field to said end user, said end user having generated said third subset of nodes by overlaying said transparent credit card on top of said login field and selecting at least one node which displays a color not being black, each node of said at least one node being selected according to a function utilizing both static and dynamic variables; and
sending said determined authenticity status to said end user via an output device.

DETAILED DESCRIPTION OF THE DRAWINGS
Definitions
The term ‘credit card’ as used herein refers to any automated teller machine (ATM) card, credit card, charge card, debit card, gift card, etc. issued by an entity which allows an end user the ability to purchase goods and/or services therewith.
The term ‘node’ as used herein refers to a single point residing within either a login field and/or a transparent credit card.
Specification
Although certain embodiments of the present invention are described herein, it is understood that modifications may be made to the present invention without departing from its course and scope. Scope of the present invention is not limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc. Furthermore, while the accompanying drawings illustrate certain embodiments of the present invention, such drawings are not necessarily depicted to scale.
FIG. 1 illustrates a graphical representation 100 of the combination 106 of transparent credit card 102 and login field 104, in accordance with embodiments of the present invention.
A transparent credit card 102 is assigned to an end user prior to an authentication attempt. The transparent credit card 102 comprises a plurality of nodes, each displaying a seemingly random color. Only the provider of said transparent credit card 102 knows the pattern of colors contained in the transparent credit card 102.
The login field 104 also comprises a plurality of nodes, each displaying a seemingly random color. The color pattern of nodes contained within the login field 104 is dynamically created each time the end user wishes to authenticate, therefore each authentication attempt will produce a different color pattern of nodes in the login field 104.
Contained within each pattern produced in the login field 104 is a first subset of nodes. Each node in the first subset of nodes matches both the color and location of a unique node residing in the transparent credit card 102. The nodes residing in the transparent credit card matching the color and location as the first subset of nodes are called the second subset of nodes.
Overlaying the transparent credit card 102 on top of the login field 104 results in the combination 106. The combination 106 displays the nodes in both the transparent credit card 102 and the login field 104 having the same color and having the same location (i.e. the first and second subset of nodes).
In one embodiment of the present invention, the login field 104 will display colors such that when the transparent credit card 102 is overlaid, if the overlaid nodes do not match in color they will therein produce a dark, i.e. black, color. The blackening of non-color matching nodes will help identify for the end user which nodes are to be selected from to effectuate the authentication attempt.
In another embodiment of the present invention, the transparent credit card 102 when overlaid on top of the login field 104 merely turns non-color matching nodes a neutral color so as to highlight the matching colored nodes more easily (see 202 in FIG. 2, infra).
The combination 106 comprises at least three different groups of differently colored nodes. At this point the end user would select the group of colored nodes which match the result of a function. The function comprises both static and dynamic information gathered by the end user and thus prevents unauthorized individuals the ability to decipher the login scheme.
If the end user properly selects the appropriately colored nodes displayed in the combination 106, then the end user would properly authenticate and gain access to secure information. However, if the end user selects the wrong color nodes, the end user is denied access to the secure information.
FIG. 2 illustrates a graphical representation 200 of an alternative combination 206 of transparent credit card 202 and login field 204, in accordance with embodiments of the present invention.
Overlaying the transparent credit card 202 on top of the login field 204 results in the alternative combination 206. The combination 206 displays the nodes in both the transparent credit card 202 and the login field 204 having the same color and having the same location (i.e. the first and second subset of nodes).
Specifically, the transparent credit card 202 when overlaid on top of the login field 204 turns non-color matching nodes a neutral and/or lightened color so as to highlight the matching colored nodes more easily.
The alternative combination 206 comprises at least three different groups of differently colored nodes. At this point the end user would select the group of colored nodes which match the result of a function. The function comprises both static and dynamic information gathered by the end user and thus prevents unauthorized individuals the ability to decipher the login scheme.
If the end user properly selects the appropriately colored nodes displayed in the combination 206, then the end user would properly authenticate and gain access to secure information. However, if the end user selects the wrong color nodes, the end user is denied access to the secure information.
FIG. 3 illustrates a method 300 for authenticating an end user, in accordance with embodiments of the present invention.
The method 300 begins with step 302 which comprises sending a login field to the end user. The login field is sent to the end user in response to the end user requesting access to the secure information. Contained within the login field is a first subset of nodes which match both the color and location of a second subset of nodes, the second subset of nodes residing in the end user's transparent credit card. The first subset of nodes is dynamically selected each time the end user wishes to authenticate thus no two instances of the first subset are the same.
In one embodiment of the present invention, the end user requests the authentication attempt by submitting a unique userID. The userID is therein used to identify the color pattern residing in the transparent credit card assigned to the end user. The pattern residing in the transparent credit card is used to select the nodes which comprise the first subset of nodes located in the login field.
After completion of step 302, the method 300 continues with step 304 which comprises receiving authentication data from the end user. Step 304 receives data comprising the locations for a set of nodes which the end user selected after overlaying their transparent credit card on top of the login field and completing a function.
In one embodiment of the present invention, the function comprises both dynamic and static variables, the static variable known only to the end user and the provider of the transparent credit card. Along with the dynamic and static variables, the provider of the transparent credit card must assign numeric values to each color present in both the transparent credit card and login field.
For example, the transparent credit card provider assigns the following colors numeric values: red=0; green=1; blue=2; yellow=3, white=4, etc. The end user must be aware of each color's numeric value before attempting to authenticate. Additionally, the static variable S represents month in which the end user was born. The dynamic variable D represents the day which the end user attempts to authenticate. Finally, a second dynamic variable C represents the number of colors present when the end user overlays the transparent credit card on top of the login field.
When the end user overlays their transparent credit card on top of the login field, the combination produces three color combination: red, green, and blue (see 206 in FIG. 2, supra). If the end user was born on Sep. 1, 1948, and attempts to authenticate on March 3rd, the function appears as follows:

Color Value=(S+D)modulo C=(3+9)modulo 3=0

Use of the modulo operation ensures that the color value calculated by use of the function matches one of the assigned color values present in the combination. Since the numeric value of zero (0) was assigned to the color red, the end user would select all the red nodes which appear in response to overlaying the transparent credit card on top of the login field.
After completion of step 304, the method 300 continues with step 306 which comprises determining whether the end user's authentication attempt is valid or invalid. Step 306 compares the nodes selected in the authentication data received pursuant to step 304 with the first subset of nodes residing in the login field.
If the authentication data received from the end user contains each and every node which both: 1) correspond to a node from the first subset of nodes residing the login field; and 2) correspond to the color value determined by use of the function identified supra, then step 306 returns a response ‘yes’ and the method 300 continues with step 308 which comprises granting the end user access to the secure information.
In one embodiment of the present invention, step 306 returns a response ‘no’ and the method 300 denies the end user access 310 if the authentication data received pursuant to step 304 contains at least one node having a color which does not correspond to the color value determined by use of the function identified supra. For example, if the authentication data contains three red node locations and one green node location where the color value calculated pursuant to the function corresponds to red, the end user's authentication attempt fails.
In an alternative embodiment of the present invention, step 306 returns a response ‘no’ and the method 300 denies the end user access 310 if the authentication data received pursuant to step 304 contains at least one node not corresponding to any node in the first subset of nodes residing in the login field.
In another alternative embodiment of the present invention, step 306 returns a response ‘no’ and the method 300 denies the end user access 310 if the authentication data received pursuant to step 304 does not contain all nodes which: 1) correspond to nodes in the first subset of nodes residing in the login field; and 2) correspond to the color value determined by use of the function identified supra. For example, if the authentication data contains only two red node locations where the first subset of nodes in the login field comprises three red nodes and the color value determined by use of the function corresponds to red, the end user's authentication attempt fails.
Step 308 comprises granting the end user access to secure information. After completion of step 308, the method 300 ends.
Step 310 comprises denying the end user who attempted to authenticate access to the secure information. In one embodiment of the present invention, after completion of step 310, the method 300 ends. In an alternative embodiment of the present invention, after completion of step 310, the method 300 returns to step 302 and sends a new login field to the end user to attempt an authentication again. The new login field would comprise a new and dynamically created first subset of nodes matching a new second subset of nodes residing in the end user's transparent credit card.
