Replication Data for: Continuous Authentication using Touch Dynamics and its Application in Personal Health Records

The dataset contains 20 data files for 20 participants with overall 125794 instances of touch dynamics information collected using TouchSense (available at https://play.google.com/store/apps/details?id=org.mun.navid.touchsens). The application is implemented in such a way that it prompts the user to type in 30 random words or numbers. While the user interacts with the keyboard, it captures the touch inputs corresponding to those actions and stores them in a data file. This dataset can be used exclusively for research purposes. Commercial purposes are fully excluded. Attribute information: 1- pressure (numeric), 2- size (numeric), 3- touchmajor (numeric), 4- touchminor (numeric), 5- duration (numeric), 6- flytime (numeric), 7- shake (numeric), 8- orientation (numeric), 9- type (numeric), 10- class (AndroidId, Others) Pressure: indicates the pressure applied by a touch action. Size: indicates the number of pixels affected on the screen by a touch action. Touch Major: reports the major axis of an ellipse that represents the touched area. Touch Minor: reports the minor axis of an ellipse that represents the touched area. Duration: represents the time interval from the moment a finger touches the screen until the finger loses contact with it. Fly Time: shows the time elapsed between finishing typing a character and starting to type the next one. Shake: records the amount of vibration of the smartphone while performing touch actions. Orientation: records whether the touch behavior was recorded while the device was in the landscape orientation or the portrait one. Word or Number: records whether the touch behavior involves typing in a word or a number.
