Abstract

Manual password entry at a User Interface is common in Automatic Teller Machines (ATM’s) or Purchase Kiosks. Since these are located in public places, there is a risk of the password being observed or recorded by an unknown person who might use the password later for fraudulent purposes. While entering the password in “not so private” areas, others can observe the sequence of key strokes and hack the passwords that are short. Physically challenged people and Senior Citizens are especially vulnerable to this problem. This idea proposes a method for assigning pseudo-elongated passwords using a short password root and ignored character definition to prevent over-the-shoulder hacking of passwords when used in public places such as Automated Teller Machine (ATM)s or Purchase Kiosks.

Password protection using pseudo long passwords

Manual password entry at a User Interface is common in Automatic Teller Machines (ATM’s) or Purchase Kiosks.  Since these are located in public places, there is a risk of the password being observed or recorded by an unknown person who might use the password later for fraudulent purposes.  While entering the password in “not so private” areas, others can observe the sequence of key strokes and hack the passwords that are short.  Physically challenged people and Senior Citizens are especially vulnerable to this problem. This idea proposes a method for assigning pseudo-elongated passwords using a short password root and ignored character definition to prevent over-the-shoulder hacking of passwords when used in public places such as Automated Teller Machine (ATM)s or Purchase Kiosks.

Closed circuit television and other cameras can also help others hacking passwords that are short. When short passwords are entered on the touch screens of ATM’s in public places, others can observe the finger movement and also use the fingerprint left behind after use to hack the password. The benefits of this proposal include enabling easy-to-remember short passwords via user-defined ignored characters, while entering a more secure long string password to avoid theft from observers.

This idea proposes a method to prevent password hacking by others looking over the shoulder or using a camera in public places by using a pseudo long password scheme.  The three solutions (S1, S2, and S3) and examples for them are given below.

S1. A certain range/set of ignore characters.  When a user sets/changes a password “a range of characters or certain characters” are defined to be “ignore characters”. The ignore characters are not known to others. When the user enters the password to login, the user includes many instances of the “Ignore characters“ in the beginning, at the end,...
