Digital forensic is defined as the process of preserving, identifying, extracting, and documenting computer evidence for use in a court of law. It involves identifying evidence stored on devices, preserving the data without alteration, analyzing the evidence using forensic tools, and documenting the findings. The key steps of the digital forensic process are identification, preservation, analysis, documentation, and presentation. Common types of digital forensics include disk, network, wireless, database, malware, email, memory, and mobile device forensics. Forensic tools used in the process include those for forensic imaging to make bit-by-bit copies of storage devices and data recovery tools to extract data from damaged sources.
Digital Forensics is the use of scientifically derived and proven methods toward the preservation, collection, validation, identification, analysis, interpretation, documentation, and presentation of digital evidence derived from digital devices.
Cyber crime is an activity done using computers and internet.
Cyber forensics is the science of collecting, examining, analyzing and reporting electronic evidence.
Computer forensics is a very important branch of computer science in relation to computer and Internet related crimes. Earlier, computers were only used to produce data but now it has expanded to all devices related to digital data. The goal of Computer forensics is to perform crime investigations by using evidence from digital data to find who was the responsible for that particular crime.
For better research and investigation, developers have created many computer forensics tools. Police departments and investigation agencies select the tools based on various factors including budget and available experts on the team.

Systematic Digital Forensic Investigation ModelCSCJournals
Law practitioners are in a uninterrupted battle with criminals in the application of digital/computer technologies, and require the development of a proper methodology to systematically search digital devices for significant evidence. Computer fraud and digital crimes are growing day by day and unfortunately less than two percent of the reported cases result in confidence. This paper explores the development of the digital forensics process model, compares digital forensic methodologies, and finally proposes a systematic model of the digital forensic procedure. This model attempts to address some of the shortcomings of previous methodologies, and provides the following advantages: a consistent, standardized and systematic framework for digital forensic investigation process; a framework which work systematically in team according the captured evidence; a mechanism for applying the framework to according the country digital forensic investigation technologies; a generalized methodology that judicial members can use to relate technology to non-technical observers. This paper present a brief overview of previous forensic models and propose a new model inspired from the DRFWS Digital Investigation Model, and finally compares it with other previous model to show relevant of this model. The proposed model in this paper explores the different processes involved in the investigation of cyber crime and cyber fraud in the form of an eleven-stage model. The Systematic digital forensic investigation model (SDFIM) has been developed with the aim of helping forensic practitioners and organizations for setting up appropriate policies and procedures in a systematic manner.
Automated Live Forensics Analysis for Volatile Data AcquisitionIJERA Editor
The increase in sophisticated attack on computers needs the assistance of Live forensics to uncover the evidence
since traditional forensics methods doesn’t collect volatile data. The volatile data can ease the difficulty towards
investigation in fact it can provide investigator with rich information towards solving a case. Here we are trying
to eliminate the complexity involved in normal process by automating the process of acquisition and analyzing
at the same time providing integrity towards evidence data through python scripting.
Digital Forensics is a technique used to search for evidence of events that have occurred. This quest aims to reveal the hidden truth. The existence of digital forensic activities due to the occurrence of crimes both in the field of computers or other. Legal treatment in digital forensic field makes this area of science a compulsory device to dismantle crimes involving the computer world. In general, the cyber crime leaves a digital footprint, so it is necessary for a computer forensics expert to secure digital evidence. Computer forensics necessarily requires a standard operational procedure in taking digital evidence so as not to be contaminated or modified when the data is analyzed. The application of digital forensic is beneficial to the legal process going well and correctly.
Incident Response Methodology is one of the popular process to investigate the incident which is unlawful, unauthorized or unacceptable action on computer system or computer network.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
