Optimizing Secure Function Evaluation on Mobile DevicesMood, Benjamin, Mood, Benjamin January 2012 (has links)
Secure function evaluation (SFE) on mobile devices, such as smartphones, allows for the creation of new privacy-preserving applications. Generating the circuits on smartphones which allow for executing customized functions, however, is infeasible for most problems due to memory constraints. In this thesis, we develop a new methodology for generating circuits that is memory-efficient. Using the standard SFDL language for describing secure functions as input, we design a new pseudo- assembly language (PAL) and a template-driven compiler, generating circuits which can be evaluated with the canonical Fairplay evaluation framework. We deploy this compiler and demonstrate larger circuits can now be generated on smartphones. We show our compiler's ability to interface with other execution systems and perform optimizations on that execution system. We show how runtime generation of circuits can be used in practice. Our results demonstrate the feasibility of generating garbled circuits on mobile devices.
This thesis includes previously published co-authored material.

Design considerations of MIMO antennas for mobile phonesUsman, Muhammad, Abd-Alhameed, Raed, Excell, Peter S. January 2008 (has links)
Yes / The paper presents a new modeling and design concept of antennas using polar-
ization diversity of 2 £ 2 and 3 £ 3 Multiple Input Multiple Outputs (MIMO) system that is proposed for future mobile handsets. The channel capacity is investigated and discussed over
Raleigh fading channel and compared to a linear/planner antenna array MIMO channel. The capacity is also discussed over three types of power azimuth spectrums. The results are compared to the constraints capacity limits in which the maximum capacity observed.

The relationship between electronic use, sleeping patterns, and EEG patternsWatts, Douglas A. 01 January 2002 (has links)
This correlation study examined the relationship among frontal EEG recordings, and self reports of computer and cell phone use and sleeping habits. Participants were 20 females and 5 males between the ages of 18 and 40. Results indicated owning a laptop was positively correlated with relative power of beta2 (21-32 Hz) in both hemispheres. Number of minutes of cell phone use per month was also positively correlated with relative power of beta2 activity in both hemispheres. Cell phone usage was also positively correlated with absolute power of SMR ( 12-15 Hz) in both hemispheres. Using a desktop for work was positively correlated with absolute power of alpha (8-12 Hz) activity in both hemispheres. Other significant relationships were also found.

The Effect of Income Inequality on Mobile Phone PenetrationSamaan, Mireille January 2003 (has links)
Thesis advisor: Timothy Duket / What is the relationship between inequality and the prevalence of mobile phones in a society? It is obvious that being poor is a barrier to owning a mobile phone, but what about simply being poorer than those around you? Stories abound about the benefits mobile phones bring to the poor in developing countries. For example, in Bangladesh's Narshingdi district, mobile phones have made it possible for families who once struggled to survive, to earn more than enough to eat well and live comfortably. These isolated villagers who grow crops or raise livestock can use their village cell phone to speak directly to wholesalers and are able to get better prices for their goods in the marketplace (Ahmed, 2000). In Cote d'Ivoire coffee growers share mobile phones to follow hourly changes in coffee prices in order to sell at the most profitable time (Lopez, 2000). But how likely will these poor people be to access a mobile phone if they are significantly poorer than the “rich” in their countries. In place where there is such a disparity, does unequal income distribution make it less likely that someone will own a cell phone, or does something about the condition make adopting this technology even more widespread? As it turns out, the results of this study indicate that the higher the level of inequality in a country, the more likely someone living there is to own a cell phone. While this result seems counterintuitive, I will discuss in detail a few ways to explain it after giving some background on the subject. / Thesis (BA) — Boston College, 2003. / Submitted to: Boston College.

The marketing implications and youth perceptions on mobile phone adult content.Ncube, Nompumelelo. January 2006 (has links)
Mobile telephony has become one of the most commonly used communication tools in the telecommunications industry. The rapid growth of mobile telephony usage and all technology developments in handsets as well as the mobile networks are generating tremendous changes in telecommunications. The changes range from sending text messages, being able to take pictures using the mobile phone, downloading content and being able to access the Internet using the mobile phone. Mobile phones have become an integral part of life and at the same time have established itself as a distribution channel of adult content. By being a distribution channel of adult content it is opening the possibility of children's exposure to adult content on their mobile phones. The availability and accessibility of adult content by the youth has marketing implications for the mobile network operators which need to be taken into account and it raises issues regarding the marketing of the product as well as the debate relating to the brand reputation, corporate image versus potential revenue generation. / Thesis (MBA)-University of Natal, Durban, 2006.
