Abstract
An alphanumeric input terminal (10) is shown in the figure which allows a user to enter a sequence of characters (40) that is compared to a stored valid entry code to determine whether access should be granted. The terminal (10) displays a random number which the user adjusts by a rotatable knob (30) to obtain a desired character (40). The character (40) is entered by pushing the knob (10). The entered character (40) is no longer displayed and the terminal displays another random character which is similarly adjusted and entered. This prevents observation of the characters (40) being entered since only one character (40) is displayed at any one time. By initially displaying a random character for each entry position, the adjustment made by the user to reach the selected character (40) is different every time. This prevents one from determining the selected character (40) by observing the direction and extent that the user rotates the knob (30) before entering the character (40).
Claims
AMENDED CLAIMS
[received by the International Bureau on 15 April 1994 (15.04.94); original claims 1, 3 and 10 amended; original claims 2, 7 and 8 cancelled; new claim 11 added; remaining claims unchanged (4 pages)]
1. An electronic input terminal, comprising: means for generating a random alphanumeric character; display means for displaying a first generated random alphanumeric character at a first position thereon; adjustment means for incrementing or decrementing the first generated random alphanumeric character displayed on said display means to obtain a first selected alphanumeric character displayed by said display means; input means for entering said first selected alphanumeric character to comparing means; said display means further including means for preventing the first selected alphanumeric character from being viewed on said display means after said first selected alphanumeric character has been entered by said input means, and for displaying at least a second random alphanumeric character generated by said generating means at a second position thereon upon entry of said first selected alphanumeric character which second random alphanumeric character can be adjusted by said adjustment means to obtain a second selected alphanumeric character which is entered to said comparing means by activation of said input means; wherein said preventing means comprises means for displaying a blocking symbol at said first position on said display means occupied by said first selected alphanumeric character upon entry of said first selected alphanumeric character by said input means; means for storing a valid entry code; said comparing means for comparing the first and second entered alphanumeric characters to a valid entry code stored in said means for storing to determine if access is permitted, and outputting a signal if the entered characters match the stored valid entry code; and
15
access means responsive to said signal for allowing access to a user of said terminal.
3. The input terminal of claim 1 wherein said display means includes a liquid crystal display which displays the blocking symbol.
4. The input terminal of claim 1 wherein said adjustment means is a rotatable knob which is rotated to adjust the first random character.
5. The input terminal of claim 4 wherein said input means responds to axial depression of said rotatable knob depressed to enter the first random character.
6. The input terminal of claim 1 wherein said adjustment means and said input means include a rotatable and axially movable knob which is rotated for adjustment and moved axially for inputting.
9. A method of providing access through an electronic input terminal upon entry of a predetermined coded sequence, comprising the steps of: a) displaying a random character in one of at least two sequenced positions on the input terminal; b) adjusting the random character to correspond to a particular element of a coded sequence; c) entering the adjusted character into said terminal; d) displaying a symbol different from the adjusted character in place of the adjusted character in the one position after said entering step; e) displaying at least a second random character in a second of said plurality of sequenced positions and repeating steps b) through d) for the second random character; f) comparing the adjusted characters entered in the input terminal to a stored valid entry code to determine if access should be granted; and g) granting access to a user upon matching of the entered adjusted characters to said stored valid entry code.
16
10. A method of inputting an access code in an electronic input terminal which provides access upon entry of a valid coded sequence, comprising the steps of: a) displaying a first random character in a display area of the input terminal; b) adjusting the first random character to obtain a first adjusted character corresponding to a particular element of a coded sequence; c) entering the first adjusted character into said terminal; d) displaying a second random character in place of the first adjusted character in the display area so that said first adjusted character cannot be viewed after being entered, while visually indicating on the input terminal that the first adjusted character has been entered; e) repeating steps b) and c) for the second random character; f) comparing the selected characters entered in the input terminal to a stored valid entry code to determine if access should be granted; and g) granting access to a user upon matching of the entered adjusted characters to said stored valid entry code.
11. An electronic input terminal, comprising: means for generating a random alphanumeric character; display means for displaying a first generated random alphanumeric character; adjustment means for incrementing or decrementing the first generated random alphanumeric character displayed on said display means to obtain a first selected alphanumeric character displayed by said display means; input means for entering said first selected alphanumeric character to comparing means; said display means further including means for preventing the first selected alphanumeric character
17
from being viewed on said display means after said first selected alphanumeric character has been entered by said input means, and for displaying at least a second random alphanumeric character generated by said generating means upon entry of said first selected alphanumeric character which second random alphanumeric character can be adjusted by said adjustment means to obtain a second selected alphanumeric character which is entered to said comparing means by activation of said input means; wherein said preventing means comprises means for displaying said second random alphanumeric character in place of said first selected alphanumeric character upon entry thereof by said input means; means for indicating entry of each of said selected alphanumeric characters by said input means; means for storing a valid entry code; said comparing means for comparing the first and second entered alphanumeric characters to a valid entry code stored in said means for storing to determine if access is permitted, and outputting a signal if the entered characters match the stored valid entry code; and access means responsive to said signal for allowing access to a user of said terminal.
