PAAS(Pride As A Service)
Strava – community of show-off athletes
• KOM (king of mountain)
• ride/run data analysis
• regular social stuff
Our “tool”
• just compress the time without jumps
• HR data stays the same
• spoof the date/time
• resampled data borrowed from other athletes is accepted by the system as a unique entry
Solution
• current
• closure of APIs
• stricter internal fraud-detection algo
• user reporting
• future?
• signed GPS logs
• correlation (physiology based)
Uber
• convenient / just one click to get a ride
• cheaper than a regular cab
• good for rider’s too
• in SF or NYC a driver can get unto 90K a month
• drivers feel safer since all the riders are “tracable”
Uber Hacks
• regular things, like lying, hedging vs Lyft
• creating new accounts with new phone numbers getting referrals (repeat)
• new scams:
• rider canceling the current ride?
• rider requesting stops that could not be proven to be initiated by rider
Gympact
ePride + real_money
• get paid to visit the gym regularly
• get penalized for every missed workout
• one could make a little money (~$25) per week
• or loose up to $50 per missed workout
• Gympact trusts GPS for correctness
