Abstract
Despite advances in biometric access to smartphones and tablets, passcodes are set to remain in use due to their simplicity and accessibility. Means of inputting passcodes using numerical keypads has proven to be vulnerable, however, to fraudulent access. The methods here leverage the increased size and resolution of screens to implement a more secure way to encode both personal identification numbers and passcodes.
