A simple cryptographic hash function may be a sufficiently acceptibleacceptable measure.

increase the entropy of the rest of the available data, there are some cases in which security can be breached and user identity can be established by an attacker.

Line 49:

## In this manner, the noise can be of lower variance and still be effective.

## Or, the noise could be unecessaryunnecessary.

## Users gain security because their behavior is partly obscured by their presence in a "crowd".

## However, in frustrating analysis of the readership behavior on smaller pages, which may cause serious limitations on studies which would like to verify claims about all of Wikipedia.
