Malware attacks are broadly disguised as useful applications. Many android apps, downloaded to perform crucial tasks or play games (take one's pick), seem to do completely different tasks, which are potentially harmful and invasive in nature. This could include sending text messages to random users, exporting the phone's contacts, etc. There exist some algorithms in place that can detect these malwares, but so far, it has been observed that many of these algorithms suffer from false negatives, which grossly reduced the effectiveness of said algorithms. The aim of this chapter is to introduce a flexible method to detect if a certain application is malware or not. The working can be loosely defined as the source of a set of applications is detected and the list of permissions is studied. The set of relevant and highly close applications is selected, and from the most relevant category, the permissions are checked for overlap to see if it can be stated as a possible anomalous application.

Image deconvolution has been an important issue recently. It has two kinds of approaches: non-blind and blind. Non-blind deconvolution is a classic problem of image deblurring, which assumes that the PSF is known and does not change universally in space. Recently, Convolutional Neural Network (CNN) has been used for non-blind deconvolution. Though CNNs can deal with complex changes for unknown images, some CNN-based conventional methods can only handle small PSFs and does not consider the use of large PSFs in the real world. In this paper we propose a non-blind deconvolution framework based on a CNN that can remove large scale ringing in a deblurred image. Our method has three key points. The first is that our network architecture is able to preserve both large and small features in the image. The second is that the training dataset is created to preserve the details. The third is that we extend the images to minimize the effects of large ringing on the image borders. In our experiments, we used three kinds of large PSFs and were able to observe high-precision results from our method both quantitatively and qualitatively.
