Claim:
1. A computerized data processing method to control access to consumer devices, the method comprising: collecting a plurality of user-specific parameter values as a user attempts to access a consumer device; determining at least two of the plurality of user-specific parameter values that uniquely identify the user; determining two or more parameter categories to which the at least two of the plurality of user-specific parameter values belong; for each of the two or more parameter categories, retrieving, from a reference database, at least one user-specific reference value that belongs to the parameter category and that has been stored in the reference database for the user; for each of the two or more parameter categories, selecting from the at least one user-specific reference value that belongs to the parameter category, a most recently obtained user-specific reference value obtained the most recently from the user; for each of the two or more parameter categories, determining whether any of the at least two of the plurality of user-specific parameter values matches the most recently obtained user-specific reference value that belongs to the parameter category; and in response to determining, for each of the two or more parameter categories, that at least one of the at least two of the plurality of user-specific parameter values matches the most recently obtained user-specific reference value that belongs to the parameter category, granting, to the user, access to the consumer device.
