Abstract
A method and associated 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 the 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.
