Building the Blocks of Knowledge – NIST Releases Draft Blockchain Technology Overview

Share

On January 25, 2018, the National Institute of Standards and Technology (NIST) division of the U.S. Department of Commerce released a draft report of Blockchain technology (Overview). Recognizing the growing public awareness of the most well-known application of Blockchain technology – Bitcoin, the Overview draft report provides a high-level discussion of the technical components of Blockchain technology, addressing how data is encrypted, and how the data is verified and then distributed among the participating Blockchain parties. NIST is seeking comments on the scope and completeness of the draft Overview, which are due by February 23, 2018.

The Overview begins with a fairly detailed, yet accessible, overview of the architecture of Blockchain technology, covering both how data that is to be recorded and encrypted in the blocks, and how the individual blocks are then incorporated into the corresponding Blockchain. Discussions of hashing, nonces, forking and Merkle Trees are included, along with helpful charts for those with a preference for visuals.

Georgetown Law Center Releases Report on Biometric Face Scans at Airport Departure Gates

Share

The Georgetown Law Center for Privacy & Technology released a report that takes a harsh look at the Department of Homeland Security (DHS)’s “Biometric Exit” program.  The “Not Ready for Takeoff: Face Scans at Airport Departure Gates” report  highlights the myriad number of privacy and fairness issues associated with the use of biometric data for screening and other purposes.   The Biometric Air Exit program uses biometric data to verify travelers’ identities as they leave the U.S. and has been deployed at Boston’s Logan International Airport and eight other airports.  The program is operated by DHS and uses photographs of passengers taken at the gate while boarding to verify travelers’ identities as they leave the country.  Prior to departure of an outbound international flight, DHS prepopulates the Traveler Verification Service (TVS) with biometric templates from the travelers expected on the flight.  TVS either confirms the travelers face or rejects the face as a “non-match.”  Non-matched travelers credentials will then be checked manually.

A.G. Schneiderman Announces SHIELD Act to Protect New Yorkers

Share

The Stop Hacks and Improve Electronic Data Security Act (SHIELD Act) was introduced in the New York legislature in early November and would amend New York’s state breach notification law.  The bill was announced after the release of a New York Office of the Attorney General report found a nearly 60% hike in data breaches affecting state residents in 2016 and following the Equifax breach in September, which A.G. Schneiderman is investigating.

Among other things, the SHIELD Act would:

  • Require reasonable security for private information, using standards tailored to the size of the business, while avoiding duplicate regulations and providing incentive to businesses that certify security compliance and provides clear examples of safeguards (e.g., technical, administrative, and physical measures).
  • Carve out “compliant regulated entities,” which are defined as those already regulated by, and compliant with, existing or future regulations of any federal or NYS government entity (including NYS DFS cybersecurity regulations; regulations under Gramm-Leach-Bliley; HIPAA regulations) by deeming them compliant with this law’s reasonable security requirement.
  • Provide safe harbor from AG enforcement actions under this law for “certified compliant entities,” (those with independent certification of compliance with aforementioned government data security regulations, or with ISO/NIST standards).
  • Provide a more flexible standard for small business (less than 50 employees and under $3 million in gross revenue; or less than $5 million in assets): requiring reasonable safeguards “appropriate to the [small business’s] size and complexity.
