A device and/or method for allowing authorization of computing device association using human-perceptible signals includes forming an association between a computing device and a further computing device. The computing device computes a fingerprint of a common key derived during the forming of the association and emits a first audio stimuli based upon the computed fingerprint. The first audio stimuli is at least one octave number apart from a second audio stimuli of the further computing device emitted by the further computing device based upon the common key.

1. A first computing device, comprising: a transmitter;a receiver;a user interface configured to emit a human perceptible stimulus;a memory in which command instructions are stored; anda processor operably connected to the transmitter, receiver, user interface, and memory, and configured to execute the command instructions to: form an association with a second computing device using the transmitter and the receiver,compute a fingerprint of a common key derived during the association formation with the second computing device, andcontrol the user interface to emit a first audio stimulus, the first audio stimulus based upon the computed fingerprint, wherein the first audio stimulus is at least one octave number apart from a second audio stimulus emitted by the second computing device based upon the common key. 2. The first computing device of claim 1, wherein: the transmitter is a wireless transmitter; andthe receiver is a wireless receiver. 3. The first computing device of claim 1, wherein the processor is further configured to execute the command instructions to emit the first audio stimulus simultaneously with emission of the second audio stimulus. 4. The first computing device of claim 1, wherein the processor is further configured to execute the command instructions to control emission of the first audio stimulus at a semitone interval with the second audio stimulus when the computed fingerprint is not identical to a computed finger print of the second computing device such that the first audio stimulus and the second audio stimulus produce a minor second. 5. The first computing device of claim 1, wherein the processor is further configured to execute the command instructions to control emission of the first audio stimulus at a semitone interval with the second audio stimulus when the computed fingerprint is not identical to a computed finger print of the second computing device such that the first audio stimulus and the second audio stimulus produce a tritone. 6. The first computing device of claim 1, wherein the processor is further configured to execute the command instructions to: apply a one-way collision resistant hash function to the computed fingerprint; andcontrol the user interface to emit the first audio stimulus in the form of a sequence of notes based upon the applied hash function. 7. The first computing device of claim 1, wherein the processor is further configured to execute the command instructions to: exchange timing information with the second computing device to enable synchronized emission of the first audio stimulus and the second audio stimulus. 8. The first computing device of claim 1, wherein the processor is further configured to execute the command instructions to: control the user interface to emit the first audio stimulus in a waveform having a shape different from a waveform of the second audio stimulus. 9. The first computing device of claim 1, wherein the first audio stimulus is the same note as the second audio stimulus when the computed fingerprint is identical to a computed finger print of the second computing device. 10. A method to allow authorization of computing device association using human-perceptible signals, comprising: forming an association between a first computing device and a second computing device;computing with the first computing device a fingerprint of a common key derived during forming of the association; andemitting with the first computing device a first audio stimulus, the first audio stimulus based upon the computed fingerprint, the first audio stimulus at least one octave number apart from a second audio stimulus of the second computing device emitted by the second computing device based upon the common key. 11. The method of claim 10, wherein the association is formed using a wireless network. 12. The method of claim 10, wherein the first audio stimulus is emitted simultaneously with emission of the second audio stimulus. 13.

The method of claim 10, wherein the first audio stimulus is emitted at a semitone interval with the second audio stimulus when the computed fingerprint is not identical to a computed finger print of the second computing device such that the first audio stimulus and the second audio stimulus produce a tritone. 15. The method of claim 10, further comprising: applying a one-way collision resistant hash function to the computed fingerprint with the first computing device, wherein the first audio stimulus is emitted in the form of a sequence of notes based upon the applied hash function. 16. The method of claim 10, further comprising: exchanging timing information between the first computing device and the second computing device; andsynchronizing emission of the first audio stimulus and the second audio stimulus using the exchanged timing information. 17. The method of claim 10, wherein the first audio stimulus is emitted in a waveform having a shape different from a waveform of the second audio stimulus. 18. The method of claim 10, wherein the first audio stimulus is the same note as the second audio stimulus when the computed fingerprint is identical to a computed finger print of the second computing device. 19. The first computing device of claim 1, wherein: the processor is further configured to execute the command instructions to implement an encoding function that inputs the fingerprint and a voice-string; andthe first audio stimulus comprises an output of the encoding function in the form of a sequence of audio signals. 20. The first computing device of claim 19, wherein: the fingerprint comprises a shortened sequence of bits indicative of the common key;the bits comprise a zero bit or a one bit at each bit position in the sequence of bits; andthe voice-string is a predetermined audio signal mapped on each zero bit or one bit at the respective bit positions.
