Abstract: An all-trinary rolling code method and system which allow a barrier opener to generate and transmit trinary rolling codes without entering or storing any rolling code values as binary words includes obtaining a stored trinary counter value upon a transmitter being actuated to remotely control a barrier. A trinary function void of trinary to binary or binary to trinary conversions is used to transform the trinary counter value to a trinary rolling code output such that the trinary rolling code output represents a trinary value that would be produced if the trinary counter value were converted to binary, mirrored, had its highest ordered bit set to zero after being mirrored, and converted back to trinary. The trinary rolling code output is combined with a stored trinary transmitter identification value to generate a trinary word. The transmitter transmits the trinary word for receipt by a receiver associated with the barrier.

Abstract: There is a need in the computer software and data industries to protect content from unauthorized access to private information. Alphanumeric passwords have been shown to offer very weak protection. Biometrics (personal traits such as fingerprints and hand-written signatures) offer superior protection, but still have a number of weaknesses. The most significant weakness is that there is no existing way to protect the stored biometric data itself; and once a person's fingerprint data has been obtained by an attacker, the use of that fingerprint can no longer be considered secure. The invention solves the problem by securing the access software application that manages the biometric data using tamper-resistant encoding techniques. These tamper-resistant encoding techniques include: data-flow, control-flow, mass-data and white-box encoding.

Abstract: A movable barrier operator having thumbprint identification in either a remote radio frequency transmitter, or a receiver/barrier operator system or both is provided.

On subsequent operation of the fingerprint detector, a fingerprint data set is received in the control circuit and an attempt is made to match the incoming data with previously stored data thus establishing the identify of the user according to highly reliable biometric principles. As an option, a variety of different actions can be taken based upon the perceived identity of a particular individual, as well as the type of device communicating with the receiver/barrier operator.

Abstract: A sensor panel having a matrix of independently decoded sensors, arranged in a two-dimensional pattern allows a consumer identification unit (CIDU) to detect a user-specific gesture made with a gesturing instrument such as an RF ID device. The CIDU monitors on a timed basis which of the sensors in the panel are receiving a signal from an RF ID device which has entered the proximity of one or more of the sensors. The user moves the sensor in a two-dimensional pattern to perform a “gesture signature” in free space near the panel, and the CIDU records the sequence of receiving sensors. This sequence can then be quickly and efficiently handled as a number to be looked up to identify and authenticate the user. Preferably, the user is allowed to define multiple signature gestures, each having the possibility of being associated with a transaction or authorization level.
