Mobile Forensic of Vaccine Hoaxes on Signal Messenger using DFRWS Framework

The COVID-19 pandemic is one of the factors that has increased the use of social media. One of the negative impacts of using social media is the occurrence of cybercrime. The possibility of cybercrime can also happen on one of the social media platforms, such as the Signal Messenger application. In the investigation process, law enforcement needs mobile forensic methods and appropriate forensic tools so that the digital evidence found on the perpetrator's smartphone can be accepted by the court. This research aims to get digital evidence from cases of spreading the COVID-19 vaccine hoaxes. The method used in this research is a mobile forensics method based on the Digital Forensic Research Workshop (DFRWS) framework. The DFRWS framework consists of identification, preservation, collection, examination, analysis, and preservation. The results showed that the MOBILedit tool could reveal digital evidence in the form of application information and contact information with a performance value of 22.22%. Meanwhile, Magnet AXIOM cannot reveal digital evidence at all. The research results were obtained following the expected research objectives

Multimedia sensors embedded in smartphones for ambient assisted living and e-health

The final publication is available at link.springer.com[EN] Nowadays, it is widely extended the use of smartphones to make human life more comfortable. Moreover, there is a special interest on Ambient Assisted Living (AAL) and e-Health applications. The sensor technology is growing and amount of embedded sensors in the smartphones can be very useful for AAL and e-Health. While some sensors like the accelerometer, gyroscope or light sensor are very used in applications such as motion detection or light meter, there are other ones, like the microphone and camera which can be used as multimedia sensors. This paper reviews the published papers focused on showing proposals, designs and deployments of that make use of multimedia sensors for AAL and e-health. We have classified them as a function of their main use. They are the sound gathered by the microphone and image recorded by the camera. We also include a comparative table and analyze the gathered information.Parra-Boronat, L.; Sendra, S.; Jimenez, JM.; Lloret, J. (2016).

Acquisition of digital evidence in android smartphones

From an expert\u27s perspective, an Android phone is a large data repository that can be stored either locally or remotely. Besides, its platform allows analysts to acquire device data, collecting information about its owner and facts that are under investigation. This way, by exploring and cross referencing that rich data source, one can get information related to unlawful acts and its perpetrator. There are widespread and well documented approaches to forensic examining mobile devices and computers. Nevertheless, they are not specific nor detailed enough to examine modern smartphones, since these devices have internal memories whose removal or mirroring procedures are considered invasive and complex, due to difficulties in having direct hardware access. Furthermore, specific features of each smartphone platform have to be considered prior to acquiring its data. In order to deal with those challenges, this paper proposes a method to perform data acquisition of Android smartphones, regardless of version and manufacturer. The proposed approach takes into account existing techniques of computer and cell phone forensic examination, adapting them to specific Android characteristics, its data storage structure, popular applications and the conditions under which the device was sent to the forensic examiner. The method was defined in a broad fashion, not naming specific tools or techniques. Then, it was deployed into the examination of six Android smartphones, addressing different scenarios that an analyst might face, and was validated to perform an entire evidence acquisition

Privacy in Gaming

Video game platforms and business models are increasingly built on collection, use, and sharing of personal information for purposes of both functionality and revenue. This paper examines privacy issues and explores data practices, technical specifications, and policy statements of the most popular games and gaming platforms to provide an overview of the current privacy legal landscape for mobile gaming, console gaming, and virtual reality devices. The research observes how modern gaming aligns with information privacy notions and norms and how data practices and technologies specific to gaming may affect users and, in particular, child gamers. After objectively selecting and analyzing major players in gaming, the research notes the many different ways that game companies collect data from users, including through cameras, sensors, microphones, and other hardware, through platform features for social interaction and user-generated content, and by means of tracking technologies like cookies and beacons. The paper also notes how location and biometric data are collected routinely through game platforms and explores issues specific to mobile gaming and pairing with smartphones and other external hardware devices. The paper concludes that transparency as to gaming companies’ data practices could be much improved, especially regarding sharing with third party affiliates. In addition, the research considers how children’s privacy may be particularly affected while gaming, determining that special attention should be paid to user control mechanisms and privacy settings within games and platforms, that social media and other interactive features create unique privacy and safety concerns for children which require gamer and parent education, and that privacy policy language is often incongruent with age ratings advertised to children and parents. To contribute additional research value and resources, the paper attaches a comprehensive set of appendices, on which the research conclusions are in part based, detailing the technical specifications and privacy policy statements of popular games and gaming platforms for mobile gaming, console gaming, and virtual reality devices

Cooperative Interactive Distributed Guidance on Mobile Devices

Mobiles device are quickly becoming an indispensable part of our society. Equipped with numerous communication capabilities, they are increasingly being examined as potential tools for civilian and military usage to aide in distributed remote collaboration for dynamic decision making and physical task completion. With an ever growing mobile workforce, the need for remote assistance in aiding field workers who are confronted with situations outside their expertise certainly increases. Enhanced capabilities in using mobile devices could significantly improve numerous components of a task\u27s completion (i.e. accuracy, timing, etc.). This dissertation considers the design of mobile implementation of technology and communication capabilities to support interactive collaboration between distributed team members. Specifically, this body of research seeks to explore and understand how various multimodal remote assistances affect both the human user\u27s performance and the mobile device\u27s effectiveness when used during cooperative tasks. Additionally, power effects are additionally studied to assess the energy demands on a mobile device supporting multimodal communication. In a series of applied experiments and demonstrations, the effectiveness of a mobile device facilitating multimodal collaboration is analyzed through both empirical data collection and subjective exploration. The utility of the mobile interactive system and its configurations are examined to assess the impact on distributed task performance and collaborative dialogue between pairs. The dissertation formulates and defends an argument that multimodal communication capabilities should be incorporated into mobile communication channels to provide collaborating partners salient perspectives with a goal of reaching a mutual understanding of task procedures. The body of research discusses the findings of this investigation and highlight these findings they may influence future mobile research seeking to enhance interactive distributed guidance

IMPLEMENTATION OF VOICE CALL TRANSFER SERVICE BETWEEN SMART PHONE AND TABLET THROUGH WI-FI

Communication through voice call leads to significant growth in technology in distant areas where two or more people from opposite ends of world will connect. This research describes a case study of voice call transfer service. This research aims at designing a system that will allow Android users to communicate over Wi-Fi. This design is able to transfer voice of incoming telephone caller over Wi-Fi network at real time through UDP. It uses client/server architecture: Server for receiving telephone call and transferring voice (one user) and client for receiving incoming caller voice and enables communication with server. Architecture designed could be used on Android smart phones with telephony enabled and tablets with telephony not enabled. Outcome of this research will allow users to communicate on real time at no cost. Proposed design gives cost effective, reliable and real time voice communication over Wi-Fi. It provides good and comfort experience to users in emergency situation where user cannot effort cost for telephone call. Proposed design is useful for educational organizations, construction buildings, shopping malls and hospitals which point to new possibilities for voice communication
