Technology firms are leaping at the chance to use the Covid-19 pandemic to ply dubious products, from useless
thermal cameras to creepy
tracking collars. The latest comes courtesy of New York Gov. Andrew Cuomo, who entered the state into a partnership with IBM to put citizens’ Covid-19 vaccine and test data on perhaps the most over-hyped technology of all: blockchain.
State officials are providing virtually no details on the high-tech coronavirus “health passport” system, raising troubling privacy questions. Furthermore, the use of blockchain technology appears completely nonsensical, lending the distinct impression that the project — trumpeted amid a series of
sexual harassment allegations against the governor — is as much about generating much-needed positive buzz for him as solving real problems.
Cuomo’s office
announced on March 2 that testing had begun on the joint IBM system, known as
Excelsior Pass. The “pass” itself is a smartphone app that displays a QR code to be scanned before entering an indoor business or other public gathering place; when verified by another device, it attests that the bearer has been vaccinated against Covid-19 or received a recent negative test result. The idea is to offer streamlined access to indoor businesses as they begin to reopen,
similar to plans in other parts of the country and throughout the world.
What sets Cuomo’s approach apart is that the data behind the Excelsior Pass lives atop a blockchain, the software technology behind Bitcoin and other digital currencies. A blockchain is essentially just a widely distributed list of data whose contents are verifiable as genuine using cryptography (essentially, complex math). Blockchains are typically public, their contents transparent to anyone with an internet connection, but the one behind Excelsior Pass will be private, meaning only parties sanctioned by IBM will be able to check the contents.
But the governor’s office and IBM, neither of which provided comment for this article, have been stingy with details, like how exactly the app works behind the scenes or why New Yorkers should trust this software with their sensitive health information. The answer to both of these questions is simply: blockchain. The press release from Cuomo’s office assures users that “robust privacy protections are woven throughout the digital health pass solution” without giving any details whatsoever as to what these protections are or what might make them robust. IBM’s public material about the system is similarly devoid of specifics.
“Gov. Cuomo gave us screenshots of the user interface, but he never even published a privacy policy,” said Albert Fox Cahn, executive director of the New York-based Surveillance Technology Oversight Project. “We have no idea how this data can be tracked and if it’s accessible to police.”
