Vijay Pandurangan, CEO of Mitro and an internet security expert, saw the buzz on Twitter about the taxi data. He noticed a comment on Reddit that questioned how the same driver was making so many trips.

Pandurangan looked at the data and saw the medallion numbers listed in the datasets were not the actual medallion numbers. The TLC used an algorithm to encrypt the numbers, a process known as hashing. Each taxi was given a unique identifier so the data could be analyzed, but the idea was that the medallion number, and thus the driver, would not be identifiable. Pandurangan recognized the type of hash the TLC used (MD5) and spent a little bit of time researching it.
Because the numbers are so structured, Pandurangan said he was able to, in laymen's terms, 'crack the code' within a few hours of looking at the data. He could take the taxi license numbers and look them up online, thus identifying the driver.
Regardless of operating a taxi, limousine or long-haul truck, a driver will need to perform basic tasks over the course of any given day. Some basic responsibilities include testing the vehicle frequently to ensure it runs properly, offering to help passengers bring any luggage onboard, washing the exterior and interior of the car, running various errands for the passenger, and collecting fares at the end of the trip.
As I stood against the bar looking out I could see them through thewindow. Frances was talking on to him, smiling brightly, looking intohis face each time she asked: "Isn't it so, Robert?" Or maybe she didnot ask that now. Perhaps she said something else. I told the barman Idid not want anything to drink and went out through the side door. As Iwent out the door I looked back through the two thicknesses of glass andsaw them sitting there. She was still talking to him. I went down a sidestreet to the Boulevard Raspail. A taxi came along and I got in and gavethe driver the address of my flat.
The Norte station in Madrid is the end of the line. All trains finishthere. They don't go on anywhere. Outside were cabs and taxis and a lineof hotel runners. It was like a country town. I took a taxi and weclimbed up through the gardens, by the empty palace and the unfinishedchurch on the edge of the cliff, and on up until we were in the high,hot, modern town. The taxi coasted down a smooth street to the Puertadel Sol, and then through the traffic and out into the Carrera SanJeronimo. All the shops had their awnings down against the heat. Thewindows on the sunny side of the street were shuttered. The taxi stoppedat the curb. I saw the sign HOTEL MONTANA on the second floor. Thetaxi-driver carried the bags in and left them by the elevator. I couldnot make the elevator work, so I walked up. On the second floor up was acut brass sign: HOTEL MONTANA. I rang and no one came to the door. Irang again and a maid with a sullen face opened the door.
Down-stairs we came out through the first-floor dining-room to thestreet. A waiter went for a taxi. It was hot and bright. Up the streetwas a little square with trees and grass where there were taxis parked.A taxi came up the street, the waiter hanging out at the side. I tippedhim and told the driver where to drive, and got in beside Brett. Thedriver started up the street. I settled back. Brett moved close to me.We sat close against each other. I put my arm around her and she restedagainst me comfortably. It was very hot and bright, and the houseslooked sharply white. We turned out onto the Gran Via. 041b061a72
