In this paper, we discuss an insider security which has been one of the biggest issues in the network security. By surveying and analyzing an issue of previous studies, we suggest an effective approach for future research. Approximately 90% of the information leakage incidents are recently being performed by internal workers. It is coming as a more serious problem than outsider attacks. The inf...

This study investigates the market reaction to dividend change announcements at the Istanbul Stock Exchange. A sample of 184 announcements made by 46 companies during the period 2005 to 2008 is analyzed by using the event study methodology. The results suggest that the market reacts positively to dividend increases, negatively to dividend decreases and does not react when dividends are not chan...

Recall from last lecture that we have several ways to model leakage. One model is “only computation leaks” by Micali and Reyzin [11], which assumes a form of secure memory that does not leak as long as no computation is done on the data. Another one is “memory leakage” by Akavia, Goldwasser, and Vaikuntanathan [1], which assumes that everything can leak information. From an orthogonal dimension...

As we enter the nanoscale regime, power reduction is of increasing importance, but the established leakage reduction techniques will become less effective. Subthreshold leakage is being joined by band-to-band tunneling and gate leakage as the primary leakage mechanisms. The increased significance of these leakage components threatens the usefulness of some traditional leakage reduction techniqu...

The DRAM cells consist of one or several MOSFET devices and the subthreshold leakage current through the MOSFET strongly depends on the temperature variation. Therefore, it is obvious that the leakage of a memory cell is highly related to temperature variation. The temperature of the circuit can be measured indirectly by using leakage sensors which can be applied to various VLSI circuits becaus...

background: apical leakage assessment is a way to compare the effi ciency of a fi lling material to seal the apical region of the tooth. many microleakage testing techniques have been introduced through the years, but there has been no agreement as to which technique gives the most accurate results. the aim of this study was to compare the accuracy of fl uid fi ltration and bacterial leakage te...

In this work, we show that strong leakage resilience for cryptosystems with advanced functionalitiescan be obtained quite naturally within the methodology of dual system encryption, recently introducedby Waters. We demonstrate this concretely by providing fully secure IBE, HIBE, and ABE systems whichare resilient to bounded leakage from each of many secret keys per user, as well as ...

A new generalised approach for multiple correlated sources over a wiretap network is investigated. A basic model consisting of two correlated sources where each produce a component of the common information is initially investigated. There are several cases that consider wiretapped syndromes on the transmission links and based on these cases a new quantity, the information leakage at the source...

Innovation is becoming more and more important in modern society. There are a lot of researches on different kinds of innovation but marketing innovation is one kind of innovation that has not been studied frequently before. Marketing innovation is defined as a new way in which companies can market themselves to potential or existing customers. The study shows some key elements for marketing in...
