Implementing security access includes mapping input elements of an input device to a coordinate system. Each of the input elements is assigned to a point on the coordinate system that is defined by respective coordinate values. The security access also includes receiving a number of inputs via corresponding input elements. An input element assigned to a first input of the number of inputs is denoted as a starting point for a sequence. Beginning with an input in the sequence that immediately follows the first input in the sequence, the security access further includes identifying a directional orientation of each of the input elements as compared to an input element immediately preceding the input element in the sequence, creating a directional pattern sequence from the directional orientation identified for each of the input elements, and providing access to an information source using the directional pattern sequence as an authentication mechanism.
