Log Anonymization and Information Management (LAIM) Working Group

The LAIM Working Group was created in 2005 to focus activities on log anonymization and data sanitization at the NCSA. These activities have been funded by the National Science Foundation (NSF)—Cyber Trust project, 0524643—and the Office of Naval Research (ONR) through the National Center for Advanced Secure Systems Research (NCASSR). The LAIM group has been led by Adam Slagell from its initiation and has included nearly a dozen members from the University of Illinois campus—who can be seen on the Team Members page.

The two main goals of the LAIM group are to (1) investigate the trade-offs between information loss and privacy inherent in the anonymization process, and (2) develop a flexible framework and prototype tool to anonymize multiple log types to varying levels. The anonymization framework we developed is called FLAIM (Framework for Log Anonymization and Information Management).

We have several publications on this site discussing topics such as measuring utility of anonymized logs, measuring the security level of an anonymized log, classifying attacks against anonymization, presenting an adversarial model of de-anonymization and negotiating anonymization policies through a predicate logic. Whenever appropriate, we have included the slides of the presentation of these publications. A separate site serves for the distribution of FLAIM.

In addition to including some publications and presentations on log anonymization topics from before LAIM was formed, we also link to some earlier anonymization tools we developed.
