Abstract

A password verifying method includes the following steps: providing a plurality of interactive regions in which several known password characters are arranged and shown randomly, at least one interactive region containing at least two characters; accepting selection of one of said plurality of interactive regions by a user, and after selection of one of the interactive regions by the user, randomly re-distributing said several known password characters into said interactive regions for subsequent selection by the user; and comparing characters contained in a predefined password sequence with characters contained in the interactive regions selected by the user, and outputting a signal representing a successful password verification when each character contained in the password sequence is identical to corresponding ones of the characters shown in respective ones of the interactive regions selected by the user.

Dependent claims

A password verifying device, comprising:

memory configured to store instructions for executing a method comprising:
(a) displaying a plurality of candidate sets of characters in respective separate interactive regions of a display screen of the password verifying device, the characters in each candidate set being randomly generated by a control unit of the device, at least one of the candidate sets containing at least two characters, the separate interactive regions of the display screen being associated with corresponding ones of a plurality of predefined labels, each of the predefined labels comprising predefined image data;
(b) receiving a user input of an individual one of the candidate sets, including:
(i) receiving feature image data comprising a face of a user and determining if eyes of the user are open or closed;
and (ii) if the eyes of the user are open, associating the feature image data with a corresponding one of the predefined labels associated with the individual one of the candidate sets;
(c) comparing each character of the individual one of the candidate sets selected by the user to a corresponding one of the characters in the password;
and
(d) re-distributing the characters in the candidate sets among the candidate sets if the individual one of the candidate sets selected by the user contains a character identical to the corresponding one of the characters in the password;
(e) repeating the receiving, comparing, and re-distributing for each of the characters in the password in the specified order, until either:
(i) the user input has been received and the candidate sets selected by the user each contain a character identical to the corresponding one of the characters for each of the characters in the password;
or (ii) if any of the candidate sets selected by the user does not contain a character that is identical to the respective one of the corresponding ones of the characters in the password;
and
(f) outputting a signal representing successful password verification if each of the individual ones of the candidate sets selected by the user contains a character that is identical to a respective one of the corresponding ones of the characters in the password,
wherein each of the separate interactive regions of the display screen is configured to be activated by a user, wherein during the receiving of the user inputs, the individual ones of the candidate sets are selected by activating the respective separate interactive regions of the display screen.

A method of verifying a password including a number of characters in a specified order, the method comprising:

(a) displaying a plurality of candidate sets of characters in respective separate interactive regions of a display screen of a password verifying device, the characters in each candidate set being randomly generated by a control unit of the device, at least one of the candidate sets containing at least two characters, the separate interactive regions of the display screen being associated with corresponding ones of a plurality of predefined labels, each of the predefined labels comprising predefined image data;
(b) receiving a user input of a selection of an individual one of the candidate sets, including:
(i) receiving feature image data comprising a face of a user and determining if eyes of the user are open or closed;
and (ii) if the eyes of the user are open, associating the feature image data with a corresponding one of the predefined labels associated with the individual one of the candidate sets;
(c) comparing each character of the individual one of the candidate sets selected by the user to a corresponding one of the characters in the password;
(d) re-distributing the characters in the candidate sets among the candidate sets if the individual one of the candidate sets selected by the user contains a character identical to the corresponding one of the characters in the password;
(e) repeating the receiving, comparing, and re-distributing for each of the characters in the password in the specified order, until either:
(i) the user input has been received and the candidate sets selected by the user each contain a character identical to the corresponding one of the characters for each of the characters in the password;
or (ii) if any of the candidate sets selected by the user does not contain a character that is identical to the respective one of the corresponding ones of the characters in the password;
and
(f) outputting a signal representing successful password verification if each of the individual ones of the candidate sets selected by the user contains a character that is identical to the respective one of the corresponding ones of the characters in the password,
wherein each of the separate interactive regions of the display screen is configured to be activated by a user, wherein during the receiving of the user input, the individual one of the candidate sets is selected by activating the respective separate interactive region of the display screen.
