Consequently, we adapt SimAttack to link a query to the p most probable users.
In addition, if the adversary considers the 10 most probable users (i.e., p=10) while the systems gather 100 users, the recall only reaches 52.8%%.
This results is counter-intuitive, as the 10 most probable users represent 10%% of the dataset, this number is expected to be close to 100%% (as there is a high probability that an initial user is among the 10 most probable users).
For instance, the adversary de-anonymizes in average only 12.9%% more queries if the 10 most probable users are targeted compared to targeting the most probable one (i.e., p=10 versus p=1).
The objective of this study was to get an initial measurement of the usability of the NIOSH AutoROPS among tractor operators who would be probable users of this new technology.
Therefore, these queries cannot be retrieved as their similarity with the user profile equals 0. Fig. 4 The number of de-anonymized queries increases according to the number of probable users returned by SimAttack.
However, depending on the intentions of the adversary, this latter might consider that the attack succeeds if the initial user is among the 3, 5 or 10 most probable users.
But now that one of the largest purveyors of user-generated content happens to be owned by a media giant like News Corp., it seems probable that user-generated video sites will begin to rein in their anything-goes impulses.
However, despite the realisation that this is very challenging, it is very likely that users will have extremely high expectations (even for automatically generated databases), which in turn makes it quite probable that users will view patent chemistry databases as not being fit for purpose for this specific task.
Plus, enough great athletes have lost medals after being judged as cheats — Ben Johnson, Marion Jones, Floyd Landis, Tyler Hamilton and dozens of our wonderful baseball players now emerging as probable drug users.
It is probable that users from these clusters had more reasons to see professionals because they suffer from multiple mental disorders and show more acute needs [ 35].
