Tilte: Pattern-sensitive Time-series Anonymization and its Application 
to Energy-Consumption Data
Authors: Stephan Kessler, Erik Buchmann, Thorben Burghardt, Klemens Böhm

Abstract: Time series anonymization is an important problem. One 
prominent example of time series are energy consumption records, which 
might reveal details of the daily routine of a household. Existing 
privacy approaches for time series, e.g., from the field of trajectory 
anonymization, assume that every single value of a time series contains 
sensitive information and reduce the data quality very much. In 
contrast, we consider time series where it is combinations of tuples 
that represent personal information. We propose (n; l; k)-anonymity, 
geared to anonymization of time-series data with minimal information 
loss, assuming that an adversary may learn a few data points. We propose 
several heuristics to obtain (n; l; k)-anonymity, and we evaluate our 
approach both with synthetic and real data. Our experiments confirm that 
it is sufficient to modify time series only moderately in order to 
fulfill meaningful privacy requirements.

Title: Perceived Sociabilityof Use and Individual Use of Social 
Networking Sites – A Field Study of Facebook Use in the Arctic
Author: Juhani Iivari

Abstract: This paper investigates determinants of individual use of 
social network sites (SNSs). It intro­duces a new con­struct, Per­ceived 
Socia­bility of Use (PSOU), to explain the use of such com­puter 
medi­ated communi­cation ap­plications. Based on a field study of 113 
Facebook users it shows that PSOU in the sense of main­taining social 
contacts is a signifi­cant predictor of Per­ceived Benefits (PB), 
Per­ceived Enjoyment (PE), attitude toward use and intention to use. 
Inspired by Benbasat and Barki, this paper also attempts to answer 
questions “what makes the system useful”, “what makes the system 
enjoyable to use” and “what makes the system socia­ble to use”. As a 
consequence it pays special focus on systems characteristics of IT 
applica­tions as poten­tial predictors of PSOU, PB and PE, intro­ducing 
seven such designable qualities (user-to-user interactivity, user 
identifi­ability, system qual­ity, information quality, usability, 
user-to-system interactivity, and aesthetics). The results indicate that 
espe­cially satisfac­tion with user-to-user inter­activity is a 
significant determinant of PSOU, and that satis­factions with six of 
these seven designable qualities have signifi­cant paths in the proposed 
nomologi­cal network.
