Local Dampening: Differential Privacy for Non-numeric Queries via Local Sensitivity

Autor: Farias, Victor A. E., Brito, Felipe T., Flynn, Cheryl, Machado, Javam C., Majumdar, Subhabrata, Srivastava, Divesh

Differential privacy is the state-of-the-art formal definition for data release under strong privacy guarantees. A variety of mechanisms have been proposed in the literature for releasing the output of numeric queries (e.g., the Laplace mechanism and

The light pollution as a surrogate for urban population of the US cities

Autor: Operti, Felipe G., Oliveira, Erneson A., Carmona, Humberto A., Machado, Javam C., Andrade Jr, José S.

We show that the definition of the city boundaries can have a dramatic influence on the scaling behavior of the night-time light (NTL) as a function of population (POP) in the US. Precisely, our results show that the arbitrary geopolitical definition

Optimal Time-dependent Sequenced Route Queries in Road Networks

Autor: Costa, Camila F., Nascimento, Mario A., Macedo, Jose A. F., Theodoridis, Yannis, Pelekis, Nikos, Machado, Javam

In this paper we present an algorithm for optimal processing of time-dependent sequenced route queries in road networks, i.e., given a road network where the travel time over an edge is time-dependent and a given ordered list of categories of interes
