Cheating in a flipped classrom

Using Weebly is a great option for having the students fill out a form that proves their attendance.  Within the assignment form, I have my students include their first and last name as well as the period.  Obviously, this does not deter the students who are going to cheat.  Even having students use their school ID number isn't going to shy away from cheating.  I'm well aware of the notion that some students will resort to having someone else do the video for them.  

• If I see the timestamps within 5 minutes of each other, I can quickly pull the students aside and ask why this happened.  
• On Weebly, you can also see the IP address that each submission came from.  Every device is given its own unique IP address, making a repeat customer a very suspicious flag.  Once again, having this issue come up is an easy resolution.  Simply hold these students after class and ask.  I had a situation where the students were at a friend's house and they did the homework together (AWESOME!).  Assume the best from your kids!
  
• Consider the amount of copying that goes on with a traditional homework assignment.  It is nearly impossible to catch.  With the flipped classroom, note checks, and form submissions, you can limit the amount of cheating that happens.
• The worst case scenario with cheating is this - a student has someone else watch the video.  The students still need to "copy" the notes from their friend in order to receive full credit for the day.  In this form of "cheating", the students are still getting some of the content by way of note-taking!
