The TLC has been a pioneer in sharing big data since 2010. With over 21,000 licensed vehicles equipped to capture GPS-enabled trip records. TLC’s trip data are valuable for policy makers, scholars, businesses and urban planners. Earlier data releases included anonymized vehicle and driver identifiers, but in 2014 they were de-anonymized and published. In response, we stopped releasing these identifiers altogether, which limits the data's usefulness. TLC would like you help to re-release this information in the most efficient manner possible.
In order to protect both drivers' and passengers' privacy, this Hackathon has two tracks:
- Track 1 - Decryption: TLC is using a new anonymization method created by the NYU Center for Urban Science and Progress and invites the cryptography community to test its strength.
- Track 2 - Passenger Privacy: We are calling out to all civic hackers to help us identify risks to passenger privacy resulting from releasing precise GPS coordinates of every trip's origin and destination. We are especially interested in uncovering vulnerabilities created by introducing additional data.
Saturday 10AM, October 15, 2016
10 E 21st St, New York, NY 10010, USA 2nd Floor
*Breakfast will be provided*
The Kickoff event will be hosted at General Assembly's Educational Facility. During this event, NYU CUSP will explain how to use their online data facility. Instructional guides will be emailed prior to the kickoff event. Attendance is not mandatory, but will help prepare you to use the online data facility. Participants that cannot attend will be able to watch a recording of the kickoff event.
General Assembly is also providing work space for participating teams during the kickoff event and throughout the Hackathon. Participants will be shown the facility and told how to enter at the Kickoff.
The ideal participants are cryptographic or privacy experts who have experience working with Big Data. However, other data scientists, academics, and computer science researchers are welcome to participate.

Track 1: De-anonymize Medallion and Hack License Data
- In the online data facility you will be supplied all yellow taxi trip records from 2014, including anonymized medallion and driver license numbers.
- Your goal is to decrypt 10% of the medallion and/or license numbers.
- Submit your de-encrypted trip records via the data facility along with a short narrative description of the method used. Please write for non-technical audiences.
- If there are any external datasets that you will need to use to decrypt this data, please let us know in the registration form. NYU CUSP will need to know this information ahead of time, in order for it to be available in their online data facility.
Track 2: Expose privacy vulnerabilities
- In the online data facility you will be supplied the same yellow taxi trip records from 2014 that are already publicly available through NYC OpenData.
- Your goal is to identify risks to passenger privacy using publicly available yellow taxi trip records.
- Submit the trip records used, supporting documentation, and a short narrative description of the method used. Please write for non-technical audiences.
- If there are any external tools or datasets that you will need to use, please let us know in the registration form. NYU CUSP will need to know this information ahead of time, in order for it to be available in their online data facility.
$400 in prizes
Free General Assembly Classes
The top team in each track will each receive a classes & workshop gift card with a total value of $200. Check out https://generalassemb.ly/ to see how you can sharpen your tech skills or learn new ones.
The members of the top team in Track 1 and the top 3 teams in Track 2 will each receive an honorary taxi medallion. (No, this doesn't mean you own a taxi. Don't even try it.)
Submitting to this hackathon could earn you:
How to enter

Track 1: De-anonymize Medallion and Hack License Data
The winner of this track will be first team to accurately decrypt 10% of the medallion and/or driver license numbers.
Track 2: Expose Privacy Vulnerabilities
The top three teams will be chosen using the criteria below:
Team used a method which exposes a passenger privacy concern that extends beyond observing a single trip, i.e. does not rely on witnessing the trip personally or with cameras (5 points)
Team exposed a passenger privacy concern with only the 2014 TLC Trip Data (10 points) ⠀⠀⠀⠀⠀⠀⠀⠀⠀ Minus 2 points for any additional datasets used
Team was able to associate multiple trips with personally identifiable information (10 points)
Team exposed passenger('s) routine/behavior (5 points)
Points for suggesting a fix for exposed concern (based on feasibility and effectiveness)
Points awarded based on: The sum of points awarded for criteria 2-4 multiplied by the quality of the fix (0 = none submitted/completely ineffective or unfeasible; 1 = moderately effective and feasible; 2 = very effective and feasible)
