- Moritz Hardt gives a tutorial on multiplicative weights in differential privacy: http://youtu.be/VeY-fqaaQv4
- Gerome Miklau gives a tutorial on the matrix mechanism and related work in differential privacy: http://youtu.be/FCIoJ77aTQ4
- Benjamin Pierce gives a tutorial on differentially private programming languages: http://youtu.be/ci2aueqZ6CU
- I give a tutorial on game theory and differential privacy: http://youtu.be/kqQ2qv0fYtQ
These tutorials all assume some familiarity with differential privacy (I don't think differential privacy is actually -defined- in any of them). For some light reading to fill in some of the background, you can check out my course notes.
