US 8,997,215 B2 · Authentication using multi-tier multi-class objects

Abstract

The invention provides a method and apparatus for authenticating a user in a touchscreen environment. A first tier may be defined having at least one object, and a destination tier may be defined having at least one bin. An authentication-key may be registered, the authentication-key comprising a length defining a number of nodes and a correct sequence of nodes, each node specifying a movement of one object from the first tier to one bin of the destination tier. A user sequence of at least one touchscreen gestures is received, each gesture specifying that one object from the first tier should be moved to one bin of the destination tier. Access is permitted if the at least one touchscreen gestures corresponds to the length, the correct sequence, and the movement of the authentication-key.

Dependent claims

A method for authenticating a user in a touchscreen environment, the method comprising:

defining a first tier having at least one object, and a destination tier having at least one bin;
registering an authentication-key, the authentication-key comprising a length defining a number of nodes and a correct sequence of nodes, each node specifying a movement of the at least one object from the first tier to the at least one bin of the destination tier;
receiving a user sequence of at least one touchscreen gestures, each gesture specifying that the at least one object from the first tier is to be moved to the at least one bin of the destination tier;
and
allowing access if the user sequence corresponds to the length, the correct sequence, and the specified movement indicated for each node, of the authentication-key.

2 more elements

An apparatus for authenticating a user, comprising:

a processor for executing program instructions;
a touchscreen display for receiving touch-based user inputs;
and
computer readable non-transitory medium carrying program instructions, the program instructions executable by the processor to:
define a first tier having at least one object, and a destination tier having at least one bin,
register an authentication-key, the authentication-key comprising a length defining a number of nodes and a correct sequence of nodes, each node specifying a movement of the at least one object from the first tier to the at least one bin of the destination tier,
receive a user sequence of at least one touchscreen gestures, each gesture specifying that the at least one object from the first tier is to be moved to the at least one bin of the destination tier, and
allow access if the user sequence corresponds to the length, the correct sequence, and the specified movement of each node of the authentication-key.
