Abstract:
1. A method for providing access, comprising: at a controller, receiving electronic signal data representative of a contour of a first key presented by a first user at a first access location; comparing the electronic signal data with stored electronic signal data, the stored electronic signal data associated with an authorized key, wherein an energy reading from a particular sample point in the received electronic signal data is compared against a particular energy level in the stored electronic signal data, and when the energy reading from the sample point in the received electronic signal data does not match the energy level in the stored electronic signal data, comparing a number of additional sample points above and below the particular sample point against the particular energy level to determine if one of the additional sample points matches the particular energy level; instructing the first access location to allow access to the user if the electronic signal data matches the stored electronic signal data; and when the electronic signal data deviates from the stored electronic signal data by at least a predetermined amount, modifying the stored electronic signal data based on the deviated electronic signal data and re-designating the modified electronic signal data as the stored electronic signal data.
