Mobile applications (apps) often transmit sensitive data through network with various intentions. Some transmissions are needed to fulfill the app's functionalities. However, transmissions with malicious receivers may lead to privacy leakage and tend to behave stealthily to evade detection. The problem is twofold: how does one unveil sensitive transmissions in mobile apps, and given a sensitive transmission,...
For advance node such as 14nm technology and beyond, back end of line interconnect has implemented self-aligned via (SAV) schemes for better via-metal short process window [1]. A TiN metal hard mask (MHM) is used for the trench pattern definition, after which via lithography and partial via (PV) etch is performed where the TiN was opened. The via etch condition has very good selectivity so that via...
This paper introduces the covariance matrix of visually salient image features as a compact and robust descriptor for near duplicate image and video copy detection. We make two novel contributions. We first present a fast method for computing information theoretic based visual saliency maps using a data independent fast transform to replace the conventional data dependent computationally demanding...
With loss aversion and game theory as research tools, this paper investigates deeply on price competition behavior between mobile commerce retailers (MCR) and traditional off-line retailers (TOR) in m-commerce era, elicits 2 kinds of market structures. Furthermore, it gives out perfect equilibrium prices as well as market scale under each condition of market structure. On this basis, two related propositions...
