Abstract

Aspects of the present invention disclose a method for encoding and transmitting access codes of a network to a computing device that is attempting to access the network. The method includes one or more processors identifying an audio command received by a first computing device. The method further includes generating a sound waveform that includes an access code of an access point, by encoding the access code into the sound waveform. The method further includes defining a sound power level of the sound waveform. The method further includes transmitting the sound waveform. The method further includes determining whether a second computing device receives the access code that is encoded in the sound waveform.

First claim

What is claimed is:

1. A method for sharing network access information, the method comprising:
identifying, by one or more processors, an audio command received by a first computing device;
generating, by one or more processors, a sound waveform that includes an access code of an access point, by encoding the access code into the sound waveform;
defining, by one or more processors, a sound power level of the sound waveform;
transmitting, by one or more processors, the sound waveform; and
determining, by one or more processors, whether a second computing device receives the access code that is encoded in the sound waveform.

2. The method of claim 1 , wherein determining whether the second computing device receives the access code that is encoded in the sound waveform, further comprises:
in response to determining that the second computing device receives the access code that is encoded in the sound waveform, wherein, the second computing device, validates network authorization access of the second computing device, monitoring, by one or more processors, communications from the second computing device for a verification message that validates network authorization access of the second computing device.

3. The method of claim 1 , further comprising:
in response to determining that the second computing device does not receive the access code that is encoded in the sound waveform, identifying, by one or more processors, transmission of an error message from the second computing device, wherein the error message includes directions; and
defining, by one or more processors, a second sound power level of the sound waveform that is greater than the first sound power level.

4. The method of claim 3 , further comprising:
determining, by one or more processors, whether the second sound power level exceeds a defined threshold, wherein the defined threshold is within a range of audible frequencies.

5. The method of claim 1 , wherein identifying the audio command received by the first computing device, further comprises:
monitoring, by one or more processors, an interface of the first computing device;
determining, by one or more processors, that the audio command includes a request for the access code of the access point; and
verifying, by one or more processors, an identity of a user providing the audio command.

6. The method of claim 1 , wherein generating the sound waveform that includes the access code of the access point, by encoding the access code into the sound waveform, further comprises:
modifying, by one or more processors, a carrier signal based on a modulating signal that corresponds to one or more characters of the access code; and
selecting, by one or more processors, a sound power level within an audible range of frequencies for transmission of the modified carrier signal.

7. The method of claim 1 , wherein determining whether the second computing device receives the access code that is encoded in the sound waveform, further comprises:
identifying, by one or more processors, a message of the second computing device; and
determining, by one or more processors, whether the message includes an indication that a demodulator of the second computing device has decoded the access code from the sound waveform, wherein decoding is based at least in part on a signal to noise ratio (SNR) of the sound waveform that includes signal distortion due to a communication channel.

8. A computer program product comprising:
one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to identify an audio command received by a first computing device;
program instructions to generate a sound waveform that includes an access code of an access point, by encoding the access code into the sound waveform;
program instructions to define a sound power level of the sound waveform;
program instructions to transmit the sound waveform; and
program instructions to determine whether a second computing device receives the access code that is encoded in the sound waveform.

9. The computer program product of claim 8 , wherein program instructions to determine whether the second computing device receives the access code that is encoded in the sound waveform, further comprise program instructions to:
in response to determining that the second computing device receives the access code that is encoded in the sound waveform, wherein, the second computing device, validates network authorization access of the second computing device, monitor communications from the second computing device for a verification message that validates network authorization access of the second computing device.

10. The computer program product of claim 8 , further comprising program instructions, stored on the one or more computer readable storage media, to:
in response to determining that the second computing device does not receive the access code that is encoded in the sound waveform, identify transmission of an error message from the second computing device, wherein the error message includes directions; and
define a second sound power level of the sound waveform that is greater than the first sound power level.

11. The computer program product of claim 10 , further comprising program instructions, stored on the one or more computer readable storage media, to:
determine whether the second sound power level exceeds a defined threshold, wherein the defined threshold is within a range of audible frequencies.

12. The computer program product of claim 8 , wherein program instructions to identify the audio command received by the first computing device, further comprise program instructions to:
monitor an interface of the first computing device;
determine that the audio command includes a request for the access code of the access point; and
verify an identity of a user providing the audio command.

13. The computer program product of claim 8 , wherein program instructions to generate the sound waveform that includes the access code of the access point, by encoding the access code into the sound waveform, further comprise program instructions to:
modify a carrier signal based on a modulating signal that corresponds to one or more characters of the access code; and
select a sound power level within an audible range of frequencies for transmission of the modified carrier signal.

14. The computer program product of claim 8 , wherein program instructions to determine whether the second computing device receives the access code that is encoded in the sound waveform, further comprise program instructions to:
identify a message of the second computing device; and
determine whether the message includes an indication that a demodulator of the second computing device has decoded the access code from the sound waveform, wherein decoding is based at least in part on a signal to noise ratio (SNR) of the sound waveform that includes signal distortion due to a communication channel.

15. A computer system comprising:
one or more computer processors;
one or more computer readable storage media; and
program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
program instructions to identify an audio command received by a first computing device;
