Authentication of an end user

摘要

A method and system for authenticating an end user. A selected subset of root nodes of a set of root nodes in a server mask is received, the selected subset of root nodes having been selected by the end user. In response to the receiving of the selected subset of root nodes, the end user is authenticated by determining that a spatial location in the server mask of each root node of the selected subset of root nodes matches a spatial position of a corresponding root node of a server set of transparent root nodes in the server mask, wherein the server set of transparent root nodes are a result of a first random selection of root nodes from the set of root nodes in the server mask.

1. A method for authenticating an end user, said method comprising:
receiving, by a computer processor, a selected subset of root nodes of a set of root nodes in a server mask, said selected subset of root nodes having been selected by the end user; and in response to said receiving the selected subset of root nodes, said processor authenticating the end user by ascertaining that a spatial location in the server mask of each root node of the selected subset of root nodes matches a spatial position of a corresponding root node of a server set of transparent root nodes in the server mask, wherein the server set of transparent root nodes are a result of a first random selection of root nodes from the set of root nodes in the server mask, wherein the server mask comprises a set of nodes, wherein each node of the set of nodes in the server mask is in a unique spatial location in the server mask, wherein the set of nodes comprises the set of root nodes, wherein a client mask comprises the set of nodes, wherein each node of the set of nodes in the client mask is in a unique spatial location in the client mask, wherein each node of the set of nodes in the client mask is either transparent or opaque, wherein the set of root nodes in the client mask consists of a client set of transparent root nodes and a client set of opaque root nodes, wherein the client set of transparent root nodes are a second random selection of root nodes from the set of root nodes, wherein the selected subset of root nodes consists of the root nodes of the client set of transparent root nodes that overlap the server set of transparent root nodes while the client mask is overlayed on the displayed server mask, and wherein the client mask had been overlayed on the displayed server mask prior to said receiving the selected subset of root nodes.
