Abstract: Systems, methods, and frameworks for detecting cryptocurrency wallet artifacts in a file system of a device are provided. The cryptocurrency wallet artifacts can be automatically detected and can include: (i) cryptocurrency wallet application folders; (ii) images containing cryptocurrency artifacts (e.g., mnemonics phrases and/or transactions information); and/or (iii) web browsers artifacts (e.g., cache data, credentials, cookies, and/or bookmarks). This information can be analyzed and extracted using machine learning (ML), natural language processing (NLP), a convolution neural network (CNN), a recurrent neural network (RNN), and/or a string search algorithm.

Abstract: Methods and systems for a near-field communication. In one aspect, a method of fabricating a relay for a near-field communication system comprises the steps of providing a flexible substrate; and providing an electric circuit on the flexible substrate, wherein the electric circuit comprises a hub inductor pattern configured to receive and transmit via electro-magnetic induction; one or more terminal inductor patterns laterally spaced apart from the hub inductor pattern relative to a surface of the flexible substrate and configured to receive and transmit via electro-magnetic induction; and a connecting trace between the hub inductor and the one or more terminal inductors.
