A forensics activity logger to extract user activity from mobile devices
(Institute of Electrical and Electronics Engineers Inc., 2019) Cedillo, Priscila
Nowadays, mobile devices have become one of the most popular instruments used by a person on its regular life, mainly due to the importance of their applications. In that context, mobile devices store user's personal information and even more data, becoming a personal tracker for daily activities that provides important information about the user. Derived from this gathering of information, many tools are available to use on mobile devices, with the restrain that each tool only provides isolated information about a specific application or activity. Therefore, the present work proposes a tool that allows investigators to obtain a complete report and timeline of the activities that were performed on the device. This report incorporates the information provided by many sources into a unique set of data. Also, by means of an example, it is presented the operation of the solution, which shows the feasibility in the use of this tool …

(Institute of Electrical and Electronics Engineers Inc., 2018) Coronel Tapia, Bryan Daniel; Cedillo Orellana, Irene Priscila; Campos Argudo, Karina Pamela; Camacho Cajamarca, Jessica Paola; Bermeo Arpi, Alexandra Elizabeth
Nowadays, with the demand of web applications there is also an increase in the number of problems and crimes that demand an investigation that requires digital forensics techniques in order to manage web evidence. Although there are several studies that address cyber forensics, they are mainly oriented to manage evidence at server side, as far as we know, no systematic literature reviews have been reported on how cyber forensics is addressed at clients’ side; considering the internationals standards. Thus, this paper presents a literature review about how cyber forensics is addressed at clients’ side related to techniques of identification, collection, analysis, preservation and report of digital evidence. Also, a review of how standards are being used in cyber forensics focused on the client side. The aim of this study is to provide a background of relevant activities that are considered by investigators to handle potentially digital evidence from web environments, considering what internationals standards are solving for this purpose. Thus, a total of 37 studies have been selected and analyzed in this study. Moreover, this study provides important insights about the need to create methodologies aligned with formal standards that support the management of the evidence in an appropriate way.
A Systematic Literature Review on Devices and Systems for Ambient Assisted Living: Solutions and Trends from Different User Perspectives
(Institute of Electrical and Electronics Engineers Inc., 2018) Cedillo Orellana, Irene Priscila; Campos Argudo, Karina Pamela; Bermeo Arpi, Alexandra Elizabeth
The aim of Ambient Assisted Living (AAL) is to help people (e.g., elderly, children) to have an independent and monitored life with the use and assistance of technology. For this population, specific technologies have been developed; many of those technologies (i.e., hardware, software) use sensors and embedded systems. Although there are many studies that address AAL approaches, no systematic literature reviews have been presented that cover hardware and software working together and take into account specific disabilities. Therefore, in this paper a systematic literature review of primary studies related to AAL is presented, which is focused on establishing software and hardware relations working together in order to solve or support specific disabilities. In this study, 3297 articles were extracted, from them only 48 were selected after applying the corresponding inclusion and exclusion criteria. Â© 2018 IEEE.
Análisis digital forense de los sensores de un teléfono inteligente para la detección y recreación de actividad motriz inusual en una localización determinada
(2016) Espinoza Farfán, David Antonio; Yánez Rodas, Juan Martín; Campos Argudo, Karina Pamela
The objective of this research is to develop a new methodology in order to detect and recreate unusual motor activity from a possible victim in a determined location. This work is framed within the field of digital forensic analysis, branch of criminology which is in charge of obtaining potential digital evidence from electronic devices with criminal purposes by applying a set of adequate techniques and procedures. This work has as its base the use of information obtained from a smartphone, so in first instance an application for the Android operative system is developed with the purpose of extracting and registering measurements from some sensors of the device. Once the information is stored it is processed and analyzed in MATLAB, from which the identification of abrupt movements is achieved regardless of the type of activity performed by the victim at the time of the incident. Finally, a desktop application is developed in the same platform, it contains a graphical interface in which is presented the digitalized reconstruction in three dimensions of the trajectory followed by the victim, as well as the geographic location of the exact site where the incident occurred. In the desktop application is also presented other information relevant to the forensic research like the resultant acceleration before and after the occurrence of unusual activity, the date and hour, number of steps taken by the victim and the total distance of displacement.

(2018) Camacho Cajamarca, Jessica Paola; Campos Argudo, Karina Pamela; Cedillo Orellana, Irene Priscila
Mobile devices have evolved vertiginously due to their massive adoption by users, who have several devices with different purposes. These devices contain greater capacity/functionality to manage information, with the embedded characteristics they become an important digital evidence container. In recent years, considerable research has been conducted on various digital electronic evidence, acquisition schemes and methods of extracting evidence from mobile devices. The research must follow protocols based on national and international standards and consider recommendations for the correct handling of the evidence. The main objective in this work is to propose a process for Digital Forensic Analysis in mobile devices, provide scientific techniques and develop a tool that provides a record of user activities. At the same time, this document contains a case study to prove its viability.
Diseño e implementación de un sistema prototipo digitalizador de señales sísmicas, empelando tecnología ZigBee para la Red Sísmica del Austro
(2018) Peñaloza García, Yadyn María; Campos Argudo, Karina Pamela
The recording of seismic signals allows early warnings systems helps reduce the risk of natural phenomena. Also evaluates the structural health of buildings to have an idea of the behavior of the structure in front of a seismic event; also these types of signal help to have a geotechnical information. Currently in the Red Sismica del Austro, the ES-300 equipment is available for the seismic refraction prospection. This equipment uses physical connectors to connect their nodes, this derives in a problem due to the cable routing and the time it takes the installation of its nodes; for this reason, the objective of this work is to implement a system for the acquisition of synchronized seismic signal through a ZigBee network. To do this, a star network topology was proposed, which has 1 master node and 13 slave nodes; also has a synchronization based on the RBS algorithm, and it was added a baseline correction, as well as the identification of the gains versus distance; all this to receive the data in a PC and present them in SEG2 format. It turned out that the digitizer worked satisfactorily in the case of a seismic prospection in which it was possible to observe and identify the arrival times of the p wave until covering a distance of 60m. Finally, it could be concluded that using the CC2530 module, this digitizer fulfilled expectations by making the maximum use of it, that is, its design was ideal for the purpose that was planned.
