Mobile Forensics : An Overview of Techniques in Mobile Forensics Investigation

Smartphone and tablet technology has changed dramatically and quickly within the last many years and continues to do so at an astounding pace. These smaller computing devices are so common, with the flexibility to replace their desktop counterparts in human-to-computer interactions. Sit in any restaurant, airport, or public place that provides Wi-Fi and you may see humans with their faces apparently glued to their device screens, interacting on their device with such focus, seemingly oblivious to their own physical surroundings. Today’s smartphones are used less for calling and a lot for socializing; this has resulted in smartphones holding plenty of sensitive information about their users. Mobile devices keep the user’s contacts from a variety of sources (including the phone, social networks, instant electronic messaging, and communication applications), data about phone calls, sent and received text messages, and e-mails and attachments. There are also browser logs and cached geolocation information; photos […]

Cryptography : A Dive Into Encryption World

Let me ask you a question. Do you want to learn about encryption hashing and secure communication? Do you want to understand what I mean when I say SHA256 or MD5? Not only that but do you want to know how all of these fit together as part of an information security plan for any organization. Well, then you’ve come to the right place. Welcome to Cryptography and if you’ve never heard of this term, be sure to read the whole article and you won’t be disappointed. Cryptography in its simplest form is the secure communication and Information sharing technique that involves certain mathematical concepts and calculations often known as algorithms, which has one main objective, which is to transfer data(messages, emails, files). Intimidated huh? Alright, let’s break it down a little bit. Whenever someone from someplace wants to send some data(Files, Video, Image, even a small text message […]

Types & Principles of Chromatography

No wonder, being a science student you must be aware of chromatography techniques. We have been studying these techniques since 12th class and are useful in most of the experiments in the lab. Chromatographic techniques are used in Forensic science laboratories too for the analysis of samples making it much more necessary for you to learn and understand. Here, I will be explaining to you different Chromatographic techniques and their principles. Introduction to Chromatography It is a separation technique in which a sample is separated based on the principle of adsorption or partition where a sample is separated into different components based on stationary and mobile phases. The stationary phase can be solid or liquid while the mobile phase can be liquid, gas, or supercritical liquid. The Term Chromatography (chroma = a color and graphien = to write) is the aggregate term for a lot of research facility methods for […]

Electrophoresis: Types & Principle You Should Know About

Electrophoresis is a separation technique where different molecules of a substance are separated depending on their capacity to travel through a stationary phase with respect to the mobile phase. The term electrophoresis is derived from two words i.e., ‘electro’ meaning electricity, and ‘phoresis’ meaning separation. Thus, it can be defined as the separation of serum proteins by the effect of electric current. Arne Tiselius won Nobel prize in Chemistry in 1948 and is considered as the Father of electrophoresis for his research and adsorption analysis for the discovery of the complex nature of serum proteins. Types of Electrophoresis Contingent on the nearness or non-appearance of supporting media the technique can be classified as Moving Boundary and Zone electrophoresis. Moving Boundary Electrophoresis Capillary Electrophoresis Isotachophoresis Immuno Electrophoresis Isoelectrofocusing Zone Electrophoresis Paper Electrophoresis Gel Electrophoresis Thin Layer Electrophoresis Cellulose Acetate Electrophoresis Moving Boundary Electrophoresis This helps in the separation of molecules in […]

5 Tools Used in Digital Forensic Labs You Should Know About

Digital forensics tools will constitute many alternative classes, a number of that embrace info forensics, disk and data capture, email analysis, file analysis, file viewers, internet analysis, mobile device analysis, network forensics, and registry analysis. several tools fulfil over one operation at the same time, and a major trend in digital forensics tools are “wrappers”—one that packages many specific technologies with totally different functionalities into one overarching toolkit. New tools are developed on a daily basis, each as elite government-sponsored solutions and basement hacker rigs. The direction for each is a bit different. a number of these transcend easy searches for files or pictures, and dig into the arena of cybersecurity, requiring network analysis or cyber threat assessment. when there’s a tool for everything, the foremost pressing question is which one to use. I have mentioned some best tools used in the Digital forensics and cybersecurity Industry. Wireshark Wireshark is a free and open-source packet analyzer. it’s used for network troubleshooting, analysis, code and protocol development, and education. Originally called Ethereal, Wireshark displays data from many different protocols on all major network varieties. data packets are […]

Role of Criminal Profiling in India & Other Countries You Should Know About

Do you know about Criminal Profiling? Don’t worry we are here to explain Criminal Profiling and Criminal Profiler in detail and the extent to which they are used in India and other countries. We all are somewhat aware of the investigation process to solve a case. As of now, you must know that it is merely a part of the process and helps significantly in the investigation when Forensic evidence and witnesses couldn’t provide enough information about the criminal. Introduction to Criminal Profiling Criminal Profiling is also known as Offender Profiling or Psychological Profiling. It is a part of the investigation which is used to identify the specific characteristics of a person and his/her psyche by analysing the comes committed by an unknown person. A pattern of the crimes committed by them is studied and a personality of that specific person is developed. The profiling is done by the […]
