Abstract: The present invention depicts systems and methods for utilizing sensors and other means that are able to track a User, and grasp his pattern of food intake (e.g., the volume, Calories, content, and other attributes of food entities), Calories outtake, and online network capabilities for tracking the balance of User Calories and other nutritional attributes.

Abstract: A system and algorithms to authenticate a person where a system only has some standard personal text data about the person, and cannot have a real biometric template obtained using an enrollment procedure. The authentication allows access to restricted resources by the person. This method is especially useful when it is used as an auxiliary authentication service with other methods such as password or Callback that dramatically lower the chances for an imposter.

Abstract: The present invention provides systems and methods for utilizing sensors of human physical features, ambient conditions, and interfacial behavior for adaptive and friendlier user interfaces for computer applications and communication environments. A user's physical characteristics, for example, age, gender, ergonometric structure and user's interfacial behavior, for example, typing speed, typing error rate and distance from the screen are used to adapt to the user needs and provide more appropriate and fitting interface. In addition, ambient conditions may be considered within the adaptation process.
