Comparison between 2 models of K-Anonymity: Incognito and Mondrian


Often organizations publish microdata for purposes such as public health and demographic research. Although attributes that could identify the individuals such as names and IDs are removed, by combining information (such as Zipcode and Birthdays) within different database, these individuals could still be identified through “Joining Attacks” – Combining 2 different database by cross-linking the similar information.

K-Anonymity has been proposed as a mechanism for protecting privacy by generalizing or suppressing certain portion of the released microdata. There had been several models of K-Anonymity since, each release attempts to improve the previous version’s weaknesses. In this paper, we will compare 2 models of K-Anonymity, namely Incognito (full-domain generalization) and Mondrian (multidimensional model), in terms of their effectiveness as well as their performance.

How to stop FortiClient from starting automatically?

Installed FortiClient recently but the challenge in disabling the application/service from running automatically on every start-up annoyed me. Attempt to stop 'FortiClient Service Scheduler' only return 'Parameter is incorrect' error message.

An article on Technet help solve my trouble. To stop FortiClient from starting automatically, try the following:
Shut down FortiClient from the system tray.
Run net stop fortishield on command prompt.
Run msconfig.
On msconfig, switch to the Services tab. Clear the FortiClient Service Scheduler check box and click Apply.Run services.msc on command prompt to open up show all available services.Look for FortiClient Service Scheduler. Switch Startup type to Manual.Restart your computer. FortiClient should not be running automatically the next time round. Hope it helps.
