FIELD OF THE INVENTION
The current invention generally relates to authentication systems and methods for providing additional security for authentication systems.
BACKGROUND OF INVENTION
Authentication is the process by which a system determines whether something is truly what it declares itself to be. In today's dynamic and diverse marketplace, authentication is vital to ensuring security and exclusivity when accessing or downloading information remotely. The most traditional authentication processes involve a username and password to log into a system. Secure keyboards, smartcards, electronic tokens, and key logger protection have provided a variety of complex and expensive means of improved security, but often fall short as hackers and identity thieves have easily tailored their software to adapt to any increased security devices. Generally, hackers plant viruses, Trojans, worms, key logging and screen recording programs to exploit the weaknesses in the authentication processes described above.
As we continue to move towards a remotely accessed marketplace, authenticating users and protecting their information has become necessary for maintaining and growing the remote marketplace. Furthermore, though authentication tokens, secure keyboards, and the like provide increased protection to the average consumer, their cost is prohibitive and they rely on a predetermined set of hardware and software devices.
The present invention overcomes these problems by allowing consumers to remotely access or download information from computers, televisions, cellular telephones, and the web in conjunction with a low cost easy to use authentication tool that uses human interaction and senses as well as simple technology to provide the average consumer with an inexpensive, convenient, highly secure, adoptable and easy to use system to remotely access information securely.
SUMMARY OF INVENTION
The present invention provides a unique Filter through which information is sieved then displayed and interpreted by the human eye. The user then processes the information and feeds back a security code into the computer. The Filter Image is presented on a visible medium and the Filter transforms the information whereby the user inputs a unique and random data to authenticate himself. The Filter image can be displayed on a computer screen, ATM screen or any similar active or passive display. The Filter Image can comprise of characters, images, or numbers in a matrix display, such as by a number of rows and columns lined up or scattered throughout the filter image. The data displayed can be in black and white, polarized or colored, such as red green, blue or other color. The data can be statically displayed with no change through the process or can alternate information in time so that a given location can display different letters or numbers at different times and with different colors.
In one embodiment of the invention, the Filter is the size and shape of a credit card. The Filter may take any other convenient shape or and size and its area is typically divided into segments. An example of the segmentation described above is a Filter with five rows and fifteen columns. A number of these segments can also have punch holes. For example, out of the seventy five potential segments eight may have open windows. These windows can be clear or open or can be a transparent color or polarized. By placing the Filter on the Filter Image the alignment of the two will display only eight images. These displayed images can be static in time or can be sequentially displayed and the image colors can change so that when a green letter is viewed through the red filtered window no image will appear. The images can be read from left to right in the static mode or as they appear in time in the timed mode. The open windows can also have numbers next to the window to designate which window is to be read first, second and so forth. The data observed by the user can also be used to prompt the user to change the information. For example, if the last number is 2, then the code is typed twice and the four visible letters become a code of eight letters. In another example, a user combines information allocated to his card to arrive at his unique authorization information.
In another embodiment of the present invention, the Filter is an active filter whereby the user looks at the image through a camera to authenticate himself/herself. In this embodiment, the user employs a camera phone where the Filter is a smart phone Application and the Filter Image is observed through the phone to authenticate the user. The active Filter can use colors that will act the same way as transparent colors on the regular Filter. The device or phone can then act as a Filter to interpret the Filter Image and authenticate the user.
In a third embodiment of the present invention, the Filter is a device such as liquid crystal windows with different colors. It can also be a device that will read digital data, such as blinking light or optical digital data from the screen transformed by the Filter and change its characteristics according to the new input information. In addition to authenticating a user, the method of the present invention can also be used to authenticate as any data, any software, video, audio or movie from various sources. It can also be coupled with electronic content to authenticate the source and to prevent malicious activity or illicit copying. The present invention can be used for securing online banking, for increased security without changing passwords regularly, securing VPN and other remote connections for employees, ATM transactions, and physical security for structures, securing credit cards and making their theft worthless for online authentication.
In essence, the current invention relates to a unique statistical arrangement for an image on a screen matrix such that the characters that are observed maximize the number of rounds that the product can handle in such a case as when a decoder tries to figure the card configuration by observing or recording the data transmitted. A unique optimization is figured whereby the screen matrix is made of letters in the same number (or very close to it) as the holes on the card and those letters are reused in the matrix. For a four hole card repeating letters on the matrix, such as xyzwxxzwwyxxx, will make it difficult to tell where the aperture that generated the specific letter exists. If there is a letter A that doesn't appear, than the intruder knows that the location of A on the matrix has no aperture, and so letters shown are used and repeated. Colors markedly increase the statistical difficulty for a spy system in its analysis of the data. Example, each hole has the statistical possibility of being clear, green, red or blue and so multiplies each hole by four possibilities and more letters can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
It is one object of the present invention to provide a secure mean of user authentication. In the preferred embodiment of the present invention, as shown in FIG. 1, once a user inputs the traditional login and password information into a computer generated user authentication screen, a Filter Image is presented onto the user's computer screen. The displayed Image will present an area on which the Filter will be placed. The manner in which the user reads the output will depend on the instructions for that specific Filter card. In the preferred embodiment of the present invention, a prompt will instruct the user how to interpret the Filter. One example of the prompt instructs the user to “type the letters as seen from left to right”. In other embodiments of the present invention, the prompt is a numbered window on the Filter card and instructs the user to type according to the sequence requested by the card numbers.
If a typing error occurs, a new set of Filter Image data is generated and can be presented. This new set of generated Filter Image data is independent of the original information. The Filter Images that appear on a user's screen may be black and white or colored Images. In one embodiment of the present invention, the Filter Image is a polarized Image and the windows on the Filter card have polarized filters.
In another embodiment of the present invention, the Filter is made of a battery operated window device. In this embodiment, the transmission can be either opened or closed in any given window by a device such as a liquid crystal. Each Filter card has multiple windows through which the images are observed.
