The ubiquity of GPS-enabled devices has resulted in an abundance of data about individual trajectories. ...
However, existing works are primarily concerned with maintaining the trajectory data geographic utility and neglect the semantic utility. ...

Code obfuscation is designed to impede the reverse engineering of a binary software. Dynamic data tainting is an analysis technique used to identify dependencies between data in a software. ...
In this paper, we present a code transformation technique meant to prevent the identification of useless results: a few lines of code are inserted in the obfuscated software, so that the results obtained ...
They should be placed closely before points where the taint is spread from a single data to multiple data. ...

One such technique is called data obfuscation in which data is deliberately modified to blur the sensitive information, while preserving the data utility. ...
The current obfuscation techniques, however, focus on the privacy of published datasets shared with untrusted parties. ...
At the time of data dissemination, the obfuscator masks the sensitive data based on contextual information. ...

The text search queries in an enterprise can reveal the users' topic of interest, and in turn confidential staff or business information. ...
To safeguard the enterprise from consequences arising from a disclosure of the query traces, it is desirable to obfuscate the true user intention from the search engine, without requiring it to be re-engineered ...

We show how semantic annotations can support the preparation of process benchmarking data by adding machine-processable semantic information to existing process models without modifying the original modeling ...
Furthermore, the annotations create the basis for an obfuscation mechanism that deals with sensitive information and acts as an additional incentive to share the data. ...
