Application Design

Chain of custody (COC) is a concept and process designed to ensure the integrity of evidence including digital evidence (DE). Also, it defines a set of procedures to document files according to its chronological [1].  In this paper, the authors design a Chain of custody application software in order to document all digital evidence in order to ensure its integrity. Thus, a chain of custody application design to document the digital evidence from the time it collected to the time where the evidence actually presented at the court to ensure the digital evidence integrity and authenticity. It can help the investigator to follow clear documentation during the investigation process because of the conventional method considered a problematic issue when it used for digital evidence. In addition to physical evidence and digital evidence have different features and characteristics.The Chain of Custody application for digital evidence is designed using the SQL and XML [3] schema approach to save case information and compute DE hash value. then compare it with its value stores in the COC tab. This solution comes as one of the solutions to enrich the existing solution of the digital chain of custody.

Digital chain of custody is the record of preservation of digital evidence from collection to presentation in the court of law. This is an essential part of digital investigation process.  Its key objective is to ensure that the digital evidence presented to the court remains as originally collected, without tampering. The chain of custody is important for admissible evidence in court. Without a chain of custody, the opposing attorney can challenge or dismiss the evidence presented. The aim of this paper is to provide a brief introduction to the concept of digital chain custody.

Evidence is anything that tends to prove or disprove a fact at issue in legal action. It involves the offering of alleged proof through testimony or objects at court proceedings to persuade the trier of fact about an issue in dispute. Islamic Evidence Law is a body of rules that helps to govern conduct and determines what will admissible in certain legal proceedings and trials. In the proceeding that involves digital evidence, the court will consider whether the digital evidence is admissible or inadmissible depends on the requirements of admissibility stated in law statutes in force and the existence of any Standard Operating Procedure (SOP). Under section 33 of the Syariah Court (Federal Territories) Evidence Act or other Syariah Evidence Enactments, digital evidence is subjected to be authenticated by the digital forensics experts. In digital forensics, the process of identification, preservation, collection, analysis, and presentation is the main procedures contained in any Standard Operating Procedure (SOP) of any digital forensics services. The court will ensure that this procedure can maintain the authenticity and the originality of the evidence especially on the issue of expert qualification, a chain of custody and analysis part. Thus, digital forensics is integrated with the Islamic law of evidence to maintain justice in delivering judgment. Therefore, this article examines the standard requirement of the admissibility of digital evidence by digital forensic methodology by using the qualitative approach on the analysis of articles, books, law statutes documents and law cases. The results show that the need for amendment of Syariah Court Evidence and Procedure statutes and the necessity of the existence of Standard Operating Procedure (SOP) on digital evidence in the Syariah courts as a guideline for judges, lawyers and parties involved.

Chain of custody plays an important role in determine integrity of digital evidence, because the chain of custody works on a proof that evidence has not been altered or changed through all phases, and must include documentation on how evidence is gathered, transported, analyzed and presented. The aims of this work is first to find out how the chain of custody has been applied to a wide range of models of the digital forensic investigation process for more than ten years. Second, a review of the methods on digitally signing an evidence that achieves the successful implementation of chain of custody through answering a few questions "who, when, where, why, what and how", and thus providing digital evidence to be accepted by the court. Based on the defined aims an experimental environment is being setup to outline practically an acceptable method in chain of custody procedure. Therefore, we have adopted SHA512 for hashing and regarding encryption RSA and GnuGP is applied where according to the defined requirement a combination of this algorithms could be adopted as a practical method.

Digital evidence has a different meaning from physical evidence, but even though it is different, both are a unity of evidence that supports each other in the investigation process. Unfortunately, laws and regulations generally have not been oriented to the terminology of digital evidence that should be. It becomes a research challenge in how the handling of digital evidence also gets the same treatment as physical evidence. For this reason, technical studies are needed to support the application of law and regulations for digital evidence handling. This article provides a solution in the form of digital evidence cabinets as a framework to support the centralization of digital evidence that following the applicable regulations of procedures for the management of evidence in the territory of Indonesia. This concept can translate the centralization of digital evidence through the analogy of physical cabinet and the interpretation of cabinet, rack, bags, and evidence unit with types of criminals, list of crimes, list of crime scenes and list of digital evidence at one crime scene.

Special Space

Computer crime has 2 types of evidence, namely: physical evidence and digital evidence. Storage on physical evidence requires a special space that can hold physical evidence. However, a system that can store and manage physical evidence is needed.The current problem is the absence of a concept of storing physical evidence and its documentation (Chain of Custody). Management of Physical Evidence is proposed as a solution to solve the problem. This concept is in the form of a Physical Evidence Management System and Chain of Custody by taking the analogy of a Data Inventory. Problems with Physical Evidence Management require a Management System for Physical Evidence that is suitable for use in the UII Digital Forensics Laboratory. This research has successfully implemented the concept of Data Inventory. It is expected that with the concept of Physical Evidence Management the control of physical evidence and all activities related to it can be maintained and documented properly.

Hash Codes

This paper addresses a problem in the field of audio forensics. With the aim of providing a solution that helps Chain of Custody (CoC) processes, we propose an integrity verification system that includes capture (mobile based), hash code calculation and cloud storage. When the audio is recorded, a hash code is generated in situ by the capture module (an application), and it is sent immediately to the cloud. Later, the integrity of the audio recording given as evidence can be verified according to the information stored in the cloud. To validate the properties of the proposed scheme, we conducted several tests to evaluate if two different inputs could generate the same hash code (collision resistance), and to evaluate how much the hash code changes when small changes occur in the input (sensitivity analysis). According to the results, all selected audio signals provide different hash codes, and these values are very sensitive to small changes over the recorded audio. On the other hand, in terms of computational cost, less than 2 s per minute of recording are required to calculate the hash code. With the above results, our system is useful to verify the integrity of audio recordings that may be relied on as digital evidence.

A Chain

The problem of relativistieally boosting the unitary representations of a non-compact spin-containing rest-symmetry group is solved by starting with non-unitary infinite-dimensional representations of a relativistic extension of this group, by adjoining to this extension four space-time translations and by the napplying Bargmann-Wigner equations to guarantee aunitary norm. The procedure has similarities to the conventional method of induced representations. The boosting problem considered here is the first step towards the solution of the problem of coupling of such infinite-dimensional representations which is also briefly investigated. Startin g from a rest-symmetry like U (6,6) a chain of subgroups GL (6), U (3,3), etc., is exhibited for collinear and coplanar processes, etc.
