Privacy of Community Pseudonyms in Wireless Peer-to-Peer Networks
2012
Journal on spesial topics in mobile networks and applications
Preserved Fulltext
We use the general concept of community pseudonyms to abstract anonymous community identification mechanisms and define two distinct notions of community privacy by using a challenge-response methodology ...
After years of research, the deployment of such peer-to-peer wireless networks is finally being considered. ...
Probabilistic Attacks In probabilistic attacks, the adversary constructs a probabilistic mapping of community pseudonyms P to communities C . ...

One solution for this problem lies in the protection of sensitive information in medical data sets by applying appropriate anonymization. ...
With recent improvements in data retrieval and processing, data mining, business intelligence and other empirical approaches have a vast potential for various fields of research. ...
Table linkage attacks determine the presence or absence of the record owner, while probabilistic attacks refer to the threat of a change in the general probabilistic belief of the attacker after seeing ...

Providing an efficient location privacy solution would be challenging due to the open nature of the WSN. Anonymity is a key solution for location privacy. ...
Wireless sensor network (WSN) is built of many sensor nodes. The sensors can sense a phenomenon, which will be represented in a form of data and sent to an aggregator for further processing. ...

In LBS, if the original location data are directly provided, serious privacy problems raise. ...
Further, we use two calculus moving and probabilistic choice to model nodes' mobility and compute its probability distribution of nodes' locations, and a renaming function to model privacy leakage. ...
Besides, many efforts are spent on the combination of k-anonymity with pseudonyms. For example, Liao et al. ...

These sensors can sense a phenomenon (motion, temperature, humidity, average, max, min, etc.) and represent what they sense in a form of data. ...
In these applications, data privacy itself might not be as important as the privacy of source location. In addition to the source location privacy, sink location privacy should also be provided. ...
Ideally, the source should update the pseudonyms only after making sure the BS receives the data. ...

AbstractThis thesis addresses the timely concern of protecting privacy in the age of big data. ...
We cast the problem of quantifying privacy as computing the estimation error in a statistical (Bayesian) inference problem, where an adversary combines his observation, background knowledge and side channel ...
He can measure the success of the attack by computing the certainty over the results. ...
