Abstract

Human ability to perceive higher audio frequencies diminishes with age. Functionality can be implemented to use a combination of audio tones with varying frequencies to identify an age range to which a user belongs and accordingly control access to age dependent access controlled information and services. The user's ability to perceive one or more audio tones in the combination of audio tones depends on the user's age. Thus, different users, depending on the users' age, may perceive the same combination of audio tones differently. Such an age verification system based on human perception of audio tones can minimize the need for identification cards and a reliance on the user providing accurate age information. This can prevent the user from misinterpreting his/her age to access the age dependent access controlled information and can ensure that only an authorized user gets access to the age dependent access controlled information.
