What it requires

  • Do not obtain access to a data system, or to data intended for use in one, without the right to do so, including by defeating an access control while scraping.

These lines are LexLint's reading of the law's text.

In the frameworks

NIST AI RMF
  • MAP 4.1Approaches for mapping AI technology and legal risks of its components – including the use of third-party data or software – are in place, followed, and documented, as are risks of infringement of a third party’s intellectual property or other rights.

Our reading of where this law's duties sit in each framework. It never says that running a control meets the law. How we read a framework against the law

Research summary

Legal information, not legal advice. This is LexLint's own research summary of a public legal source, and it creates no attorney-client relationship. For decisions that matter, consult qualified counsel in the relevant jurisdiction. About LexLint

Section 263, subsection 1, punishes with a fine or imprisonment of up to 1 year and 6 months whoever unlawfully obtains access to another's data system or to data intended for use in a data system. The provision does not state that the access must defeat a security measure, so its text does not on its face exclude reading a public, unauthenticated page.

Subsection 3 raises the maximum to imprisonment of up to 6 years where the access is made with intent to learn a business's trade secrets or under other especially aggravating circumstances, including systematic or organized offending. A related section, 263a, separately punishes commercial trafficking in access credentials to a data system.
