SYSTEMS AND METHODS FOR MANAGING ACCESS TO A VEHICLE OR ANOTHER OBJECT USING ENVIRONMENTAL DATA

摘要

Systems and methods for controlling access to a vehicle or other object are provided. A vehicle-based authentication unit and a mobile access device, e.g. For example, a key fob that communicates wirelessly with the vehicle-based authentication unit may each include environmental sensors that collect respective environmental data locally for the particular device / unit, e.g. GPS data, local temperature data, local barometric pressure data, etc. The mobile access device sends an access request message (eg, a response to a request from the vehicle-based authentication unit) containing environmental data acquired by the on-board sensor (s). The vehicle-based authentication unit receives the access request message and, based on the environmental data included in the message, determines whether access to the vehicle is to be granted. For example, the authentication unit may compare the environment data in the access request message with corresponding environmental data collected from sensor (s) on the vehicle or with other reference data (eg, user-specific fingerprint data).
