Saturday 30 July

Guided Nassagaweya Canyon hike at the Crawford Lake Conservation Area

Space is limited; RSVP as soon as possible to gc11@petsymposium.org.

12:00 noon (SHARP!) until about 6 pm
Length: about 7 km
Difficulty: moderate

Things to bring:

• water (required)
• sturdy hiking shoes (strongly suggested)
• snacks (not required, but hey, who can argue with snacks?)
• sun screen
• bug spray
• a hat

Note: Lunch will not be available, so eat before boarding the bus.

The bus trip is about 45 minutes each way; there are no restrooms on the bus.

If you'd like to come on the trip, but can't or don't want to complete the main hike, there are shorter, easier trails you can explore on your own. The conservation area also includes a 15th century Iroquois village reconstructed on its original site.

There is no additional charge for the hike for PETS attendees.

Invited Speakers

Sid Stamm

Sid Stamm is the lead privacy engineer at Mozilla. He is working on making the web a safer place for everyone, and has been instrumental in designing and developing many of the security and privacy-related features in Firefox including Content Security Policy and the Do Not Track header. He has published many academic papers on privacy, security and anti-fraud. He holds a Ph.D. in computer science from Indiana University.

Abstract: The growth of data sharing on the web is rapid and biased towards making shiny new things. New types of web applications pop up every day, and with fast innovation in data mining and analytics, the smallest bits of information about you can be valuable. While the complexity and robustness of web applications is quickly expanding, people's ability to control what happens with their information needs to grow fast enough to match. This talk discusses what Mozilla knows about needs for better privacy and anonymity, and what they're doing about it. There is lots of work to be done, and with a little focus and help we can put people back in control of what is done with their data.
