  2.  
  3. "Abstract-Covert channels can be used to circumvent system and network policies by establishing communications that have not been considered in the design of the computing system. We construct a covert channel between different computing systems that utilizes audio modulation/demodulation to exchange data between the computing systems over the air medium. The underlying network stack is based on a communication system that was originally designed for robust underwater communication. We adapt the communication system to implement covert and stealthy communications by utilizing the near ultrasonic frequency range.

  1. Back in California, when I raised the issue of too much homework on that e‑mail chain, about half the parents were pleased that someone had brought this up, and many had already spoken to the math teacher about it. Others were eager to approach school officials. But at least one parent didn’t agree, and forwarded the whole exchange to the teacher in question.
  2.  
  3. As the person who instigated the conversation, I was called in to the vice principal’s office and accused of cyberbullying. I suggested that parents’ meeting to discuss their children’s education was generally a positive thing; we merely chose to have our meeting in cyberspace instead of the school cafet
