Original Information

Currently, the changes in image quality resulting a low-resolution images, faded colors, and so on. This condition potentially attract irresponsible parties to take advantage of the situation for certain purposes. Nowadays, it is very easy for people to manipulate, change, or delete the original information from a digital image thus cause the authenticity and integrity of the image to be doubted. This study is conducted in a specific objective to prove the authenticity of a digital evidence for analysis by providing detailed illustrations of the role of Digital Forensics in accordance with applicable legal regulations in Indonesia using the NIST workflow. The research flow begins with uncovering the background of the problem, collecting data, making scenarios, applying the NIST method, and making conclusions. The illustration used in the scenario is a video inserted into a digital evidence. The video used in this research is the Cyanide Coffee Case with the suspect Wayan Mirna Salihin, happened in August 16, 2016 which was uploaded by Kompas TV channel on Youtube. The NIST analysis phases used several tools: Exiftools, Forevid, and Video Cleaner. The result indicates that all phases in the NIST method are correlated to each other. The result is specifically very clear in the collection phase. The discovery of hidden information causes the examination and analysis process to be more complex especially the extraction process of digital evidence in the form of images. Indeed, the use of various tools are more helpful in disclosing the existing information. This information can be seen from the results of metadata, hash value, and image sharpness from the analyzed digital evidence.

Security Incidents

The article presents interpretations of the concepts of cybersecurity and cybercrime as well as the abuse of the term cybernetic. The author refers to information as a new “centre of gravity” of the nation’s power and special attention is paid to activities aimed at ensuring a high level of information security in Poland. The assumptions of the draft Act on the national cybersecurity system are described and particular emphasis is placed on the issues of technical and organisational reporting and the handling of ICT security incidents. The author points out that handling incidents violating cyber security at a strategic level for a country ought to be considered as an intentional action of a definite and repeatable character. Here the reference to the ISO/IEC standards and recommendations can be found. Moreover, behaviours related to securing digital evidence after an incident, including the so-called good practice in relation to the reaction in the event of an incident, are presented. A simplified procedure for securing computer hardware, as a recommended method of action in case of the triage and live data forensics, are suggested in the article. The recommendations of the FORZA methodology and frameworks are also discussed. When summarising, the author underlines that it is essential to prepare appropriate procedures and personnel for the broadly understood handling of incidents violating cybersecurity. This includes protection of digital evidence according to the procedures, good practice and suggestions contained in normative documents, as well as implementing cybersecurity policy, bringing legislation into line with international standards and educating users and the judiciary.

The development of instant messenger, especially Skype applications is growing rapidly. Skype users are usually used as tools to share information using an Android smartphone. The large number of Skype users can be misused for carrying out criminal activities such as illegal goods transactions in the form of vape drugs among Skype users. This case can be resolved by getting digital evidence from the Skype application left on an Android smartphone using the Forensic Digial method. The forensic method used in this study is the National Institute of Justice (NIJ) with several stages, namely identification, collection, examination, analysis, and reporting while the Oxygen Forensic Suite software is used for data acquisition. The results obtained successfully obtained all the desired evidence from the two smartphones that installed Skype, namely EVERCROSS and SAMSUNG J2 in the form of a profile account, contact person, conversation text and image file with the percentage of Skype data acquisition results from the EVERCROSS B75 smartphone succeeding in getting 48% data, and Skype data acquisition results from SAMSUNG J2 managed to get 100% data.

Descriptive Method

This paper discusses about how to build a data warehouse (DW) in business intelligence (BI) for a typical marketing division in a university. This study uses a descriptive method that attempts to describe the object or subject under study as it is, with the aim of systematically describing the facts and characteristics of the object under study precisely. In the elaboration of the methodology, there are four phases that include the identification and source data collection phase, the analysis phase, the design phase, and then the results phase of each detail in accordance with the nine steps of Kimball’s data warehouse and the Pentaho Data Integration (PDI). The result is a tableau as a tool of BI that does not have complete ETL tools. So, the process approach in combining PDI and DW as a data source certainly makes a tableau as a BI tool more useful in presenting data thus minimizing the time needed to obtain strategic data from 2-3 weeks to 77 minutes.

Edge detection is the first step to cover information in the image. The edges characterize the boundaries of objects and therefore edges are useful for the process of segmentation and identification in the image. The purpose of edge detection is to increase the appearance of the boundary line of the object in the image. The sobel method is a method that uses two kernels measuring 3x3 pixels for gradient calculations so that the estimate gradient is right in the middle of the window. Digital image processing aims to manipulate image data and analyze an image with the help of a computer. Matlab is made to facilitate the use of two collections of subroutines in the fortran library, linpack and eispack, in handling matrix computing, and develops into an interactive system as a programming language. Experimental results from the input image research, namely the flower image have different MSE values because each input image has a different pixel value

The dynamical scattering effect, which can be described as the failure of the first Born approximation, is perhaps the most important factor that has prevented the widespread use of electron diffraction intensities for crystallographic structure determination. It would seem to be quite certain that dynamical effects will also interfere with structure analysis based upon electron microscope image data, whenever the dynamical effect seriously perturbs the diffracted wave. While it is normally taken for granted that the dynamical effect must be taken into consideration in materials science applications of electron microscopy, very little attention has been given to this problem in the biological sciences.

Image Management System

One of the most common tasks in a typical analysis lab is the recording of images. Many analytical techniques (TEM, SEM, and metallography for example) produce images as their primary output. Until recently, the most common method of recording images was by using film. Current PS/2R systems offer very large capacity data storage devices and high resolution displays, making it practical to work with analytical images on PS/2s, thereby sidestepping the traditional film and darkroom steps. This change in operational mode offers many benefits: cost savings, throughput, archiving and searching capabilities as well as direct incorporation of the image data into reports.The conventional way to record images involves film, either sheet film (with its associated wet chemistry) for TEM or PolaroidR film for SEM and light microscopy. Although film is inconvenient, it does have the highest quality of all available image recording techniques. The fine grained film used for TEM has a resolution that would exceed a 4096x4096x16 bit digital image.
