Patents by Inventor Thomas Emmanual Varghese

Thomas Emmanual Varghese has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9106422
    Abstract: Embodiments of the present invention provide techniques for authenticating users based on personalized (i.e., user-provided or user-selected) authentication data. In one set of embodiments, the personalized authentication data includes acoustic, image, and/or video data, but is exclusive of biometric data of the user. In this manner, existing acoustic, image, and video-based authentication interfaces/mechanisms may be leveraged, without the problems associated with verifying biometric data. In some embodiments, a user may enroll or register multiple pieces of personalized authentication data into an authentication system. The user may then select one piece of personalized authentication data for use by the system at a time of authentication.

  • Patent number: 8739278
    Abstract: Techniques for fraud monitoring and detection using application fingerprinting. As used herein, an “application fingerprint” is a signature that uniquely identifies data submitted to a software application. In an embodiment, a plurality of historical application fingerprints are stored for data previously submitted to a software application. Each historical application fingerprint is associated with one or more contexts in which its corresponding data was submitted. When new (i.e., additional) data is subsequently submitted to the application, a new application fingerprint is generated based on the new data, and the new application fingerprint is associated with one or more contexts in which the new data was submitted. The new application fingerprint is then compared with one or more historical application fingerprints that share the same, or substantially similar, context(s).

  • Patent number: 8484455
    Abstract: Systems and methods for providing encryption and decryption of data transmitted on a computer implemented network, preferably user authentication identifier data, such as a password, at the point of entry into the user's computer. The systems and methods enable an end user to mentally select a marker from one of the randomly arranged elements on a first portion of a graphical image. A second portion of the graphical image includes an arrangement of possible elements of any individual authentication identifier sequence, and is positioned adjacent to the first portion. The systems and methods prompt a user to enter each element of the identifier by moving the selected marker and the first portion as necessary to substantially align the selected marker with a chosen element of the authentication identifier appearing on the outer portion. According to one embodiment, the image portions are concentric wheels. According to another embodiment, the image portions are arranged in adjacent rows.

  • Patent number: 7908645
    Abstract: The present invention provides systems and methods for authenticating access requests from user devices by presenting one of a plurality of graphical user interfaces selected depending on a perceived risk of fraud associated with the devices. User devices are identified with fingerprinting information, and their associated risks of fraud are determined from past experience with the device or with similar devices and from third party information. In preferred embodiments, different graphical user interfaces are presented based on both fraud risk and, in the case of a known user, usability. In preferred embodiments, this invention is implemented as a number of communicating modules that identify user devices, assess their risk of fraud, present selected user interfaces, and maintain databases of fraud experiences. This invention also includes systems providing these authentication services.
