Information Security in Big Data: Privacy and Data Mining

TL;DR: This paper identifies four different types of users involved in data mining applications, namely, data provider, data collector, data miner, and decision maker, and examines various approaches that can help to protect sensitive information.
Journal ArticleDOI

Preparations and photocatalytic hydrogen evolution of N-doped TiO2 from urea and titanium tetrachloride

TL;DR: In this article, X-ray photoelectron spectroscopic measurements showed that the N presented in TiO2 was in the state of both molecularly chemisorbed N2 and substituted N.
Journal ArticleDOI

TiO2 nanotubes incorporated with CdS for photocatalytic hydrogen production from splitting water under visible light irradiation

TL;DR: In this paper, the CdS/TiO2 composites were synthesized using titanate nanotubes (TiO 2NTs) with different pore diameters as the precursor by simple ion change and followed by sulfurization process at a moderate temperature.
Journal ArticleDOI

Coalitional Games for Resource Allocation in the Device-to-Device Uplink Underlaying Cellular Networks

TL;DR: This paper addresses the uplink resource allocation problem for multiple D2D and cellular users from a game theory point of view and proposes a coalition formation game based scheme, which achieves the close optimum solution obtained by the centralized exhaustive algorithm and enhances the system sum rate by about 20%-65% without sacrifice of resource sharing fairness.

Steganography in Inactive Frames of VoIP Streams Encoded by Source Codec

TL;DR: It is revealed that, contrary to existing thought, the inactive frames of VoIP streams are more suitable for data embedding than the active frames of the streams; that is, steganography in the inactive audio frames attains a largerData embedding capacity than that in the active audio frames under the same imperceptibility.
