  If for any short time period the [=interest cohorts=] exposed to different sites tends to be the same, then the time series of [=interest cohorts=] can also be used as a user identifier. Sites could associate users' first-party identity with a series of [=interest cohorts=] observed over time, and could report these series to a single tracking service. The tracking service could then associate each series with the sites to know the browsing history of an individual.
 
- Computing the [=interest cohorts=] on-the-fly should make it less likely for different sites to observe the same [=interest cohort=] for a given user. However, those distinct [=interest cohorts=], when casting to a lower dimension, may still be identical, and the above concern still applies though to a lesser extent.

  Updating the [=interest cohort=] too often may let a given site learn too much about the user. An attacker could attempt to use <a href="https://en.wikipedia.org/wiki/Compressed_sensing">compressed sensing</a> to recover the browsing history.
