- zamadatix 8y agoHistorically they just make it more complicated http://www.dc949.org/projects/stiltwalker/ http://www.dc949.org/projects/stiltwalker/ Steganography prevents for people to use their exact service while making it more difficult in general prevents people from using any existing service.
- ilovetux 8y agoI think a simpler solution would be to check if a text to speech API request resulted in the correct answer as part of validating a captcha submission.
- desas 8y agoThere are other free text to speech APIs.
- dwd 8y agoYou would think they could apply a hidden track at a certain frequency that is inperceptable to a human or a pattern of changes in volume to prevent it being passed through their API. Of course the next step will be to resample the sound to remove the steganography...and the arms race continues.

- jdietrich 8y agoThe obvious approach would be to generate adversarial examples. https://blog.openai.com/adversarial-example-research/ https://blog.openai.com/adversarial-example-research/
