  • Patent number: 10303864
    Abstract: A user authentication tool continuously authenticates the user of a computing device during an electronic communication session. A trusted user profile includes keypad pressure applied by the trusted user when depressing characters on a virtual keypad displayed on the computing device touch screen. Keypad pressure applied by the current user of the computing device is continually monitored during the current electronic communication session. The monitored keypad pressure applied by the current user is compared to the keypad pressure in the trusted user profile. A confidence score is generated based upon the compared keypad pressures of the current user and the trusted user, the confidence score being indicative of the likelihood that the current user is the trusted user of the computing device. The computing device is automatically required to re-authenticate the current user as the trusted user if the generated confidence score is below a predefined minimum confidence threshold.

  • Publication number: 20170063831
    Abstract: A method for authenticating a user having a username and password and authenticating access to the user's information. A client computer generates, and sends to a server computer, input data that includes a key (h1) to a dataset of salts accessible to the server computer, a proxy (h2) for the password, a proxy (h4) for the username, and in one embodiment, a different proxy (h8) for the username. The input data does not include the username in plaintext and does not include the password in plaintext. Using the input data and not utilizing the username in plaintext and not utilizing the password in plaintext, the server computer authenticates both the user and access to the user's information, after which the server computer sends, to the client computer, notification that the server computer has authenticated both the user and access to the user's information.
