The popularity of Android brings many functionalities to its users but it also brings many threats. Repacked Android application is one such threat which is the root of many other threats such as malware, phishing, adware, and economical loss. Earlier many techniques have been proposed for the detection of repacked application but they have their limitations and bottlenecks. In this work, we proposed an image similarity based repacked application detection technique. The proposed work utilized the main idea behind the repacking of application that is “the attacker wants to create fake application looking visually similar to the original". We convert each APK file into a grayscale image and then use perceptual hashing for creating a hash of each image. The string distance algorithms like Hamming distance was used to calculate the distance and searching for the repacked application. The proposed work also used distance calculation on binary features extracted from the app. The proposed work is very powerful in terms of detection accuracy and scanning speed and we achieved 96% accuracy.

: Traditional network-based computational methods have shown good results in drug analysis and prediction. However, these methods are time consuming and lack universality, and it is difficult to exploit the auxiliary information of nodes and edges. Network embedding provides a promising way for alleviating the above problems by transforming network into a low-dimensional space while preserving network structure and auxiliary information. This thus facilitates the application of machine learning algorithms for subsequent processing. Network embedding has been introduced into drug analysis and prediction in the last few years, and has shown superior performance over traditional methods. However, there is no systematic review of this issue. This article offers a comprehensive survey of the primary network embedding methods and their applications in drug analysis and prediction. The network embedding technologies applied in homogeneous network and heterogeneous network are investigated and compared, including matrix decomposition, random walk, and deep learning. Especially, the Graph neural network (GNN) methods in deep learning are highlighted. Further, the applications of network embedding in drug similarity estimation, drug-target interaction prediction, adverse drug reactions prediction, protein function and therapeutic peptides prediction are discussed. Several future potential research directions are also discussed.
