FUTURE OF DIGITAL FORENSIC




Introduction-: Digital forensics deals with the recovery and investigation of fabric found in digital devices. It includes investigation of each device capable of storing digital data. The discipline emerged completely within the 21st century with the emergence of national policies. it's applications in criminal or civil courts to support or refute a hypothesis. Digital forensics is additionally partitioned into a couple of branches - computer, mobile device, network, forensic data analysis and database forensics.
Forensic science is relatively new field and cyber forensics is even newer. There are different fields of cyber forensics and each field in itself is extremely difficult to practice. Nevertheless, significance of cyber forensics can't be undermined especially in contemporary times of space laws, AI and Internet of Things (IoT).
Future Paradigms-: Many of the digital forensics’ tools tailored to discovering evidence are expected to reside on the suspect’s device, but offer limited features for investigating unknown and complex environments, including big data–like sources. The majority of forensic software is unsuitable for identifying anomalies in an automatic or unattended way. One of the major challenges to be addressed within the near future, therefore, is that the creation of tools and techniques to research the bulk of knowledge and report possible digital clues to the examiner for further investigation. Such tools and techniques’ engineering, including proper visualization features to assist the forensic examiner, may be a complex task, particularly due to the shortage of unified standards and the nontrivial computational requirements. Digital investigation can leverage the features of cloud computing, as an example, to dump the foremost demanding operations of digital forensics procedures, such as log analysis, data indexing, and multimedia processing. One of the most interesting aspects of the cloud is that the opportunity to take advantage of a replacement paradigm during which forensics is provided as a utility like forensics as a service (FaaS). For example, a tool was developed for indexing forensic disk images which will be easily employed by investigators through an internet interface. A further advantage of pursuing an FaaS paradigm is that the possibility of concentrating the software during a single point, which makes updates and improvements easier. This can also hide complexity from end users, allowing professionals to concentrate on the investigation. Similarly, digital investigations can leverage the proliferation of software-defined networking techniques, which supply additional layers of abstraction useful for analysing attacks or infections without the necessity for resource-consuming traffic analysis campaigns. Lastly, digital forensics could quickly become essential even in new and unforeseen scenarios. IoT usage creates some extent of interaction between the cyber and physical worlds, making digital IoT forensics an effective way to collect information about the nondigital environment as well. Obviously, such investigations are linked to further privacy issues especially as sensors could be influenced not only by one user but by an undefined set of influencers several individuals could trigger a presence sensor during a room every day, not just the potential criminal.

THE DOCTRINE OF SEPARATION OF POWER

Image
                           Based on the principle of trias politica, the Doctrine of Separation of Power has been in existence in India since the days of “Magna Carta”. The Doctrine of Separation of Power envisages a division of powers in a tripartite system. The Indian system is formulated on three main organs; the legislative organ of the state makes laws, the executive forces them and the judiciary applies them to any cases arising out of the breach of those laws. The concept of Separation of Power as elucidated by Wade and Philips meant that no same individual should be a part of more than one out of the three organs of the government. It was further interpreted that one organ of the Government ought not to control or interfere with the activity of another organ, for example, the Judiciary ought to be free of the Executive and that one organ of the Government ought not to exercise the functions of another, for ex...

PROPERTY DIVISION IN MUSLIM LAW

Image
INTRODUCTION Succession is both a legal and a practical requirement. Every individual will be required to renounce the world once, after which all of their legal rights and responsibilities will be dissolved and transferred to someone else. In India, succession is governed by religiously based personal laws. As a result, the rule of succession is influenced by one's faith on religion. “THE MUSLIM PERSONAL LAW (SHARIAT) APPLICATION ACT, 1937”, deals with intestate succession, the special property of women, inheritance, and the transfer of property under a gift or any other provision that is a subject of personal law among Muslims. DIVISION In Muslim law, the two forms of succession are also recognised. In the event that a man leaves a valid will, testamentary succession occurs, and the property is divided according to the will. When a person dies without leaving a will, intestate succession takes place. Since the joint family system is not recognised, the heirs are limited to t...

DELAYED JUSTICE IN DEATH PENALTY

Image
Justice is rightly called the shield of innocence and guardian of civil rights, as Martin Luther King said, “injustice anywhere is threat to justice everywhere”.  Justice basically means being just, impartial, fair and right. Justice to the accused/convict is as important as justice to the victim. Capital punishment has been in talk in India and other countries as well. In 1982, in the Bachan Singh Vs State of Punjab, the Supreme Court propounded the “rarest of rare” doctrine and since then, life sentence is the rule and the death sentence the exception. Capital Punishment is awarded in cases related to rape, murder, terrorism and atrocity. In Law Commission of India’s report on Death Penalty in 2015, it was stated that there were 12 crimes under IPC and 22 other laws which prescribed death penalty. In 2019, the NDA government amended the POCSO Act in order to grant death penalty to those who indulge in aggravated sexual assault against children.  William Edward Gl...
