Towards the Data Security and Digital Evidence based Solution in Bangladesh Perspective

Shekh Abdullah-Al-Musa Ahmed, Nik Zulkarnaen Khidzir, Tan Tse Guan



Data is anything in a form suitable for use with a computer. Data is often distinguished from programs. A program is a set of instructions that detail a task for the computer to perform. In this sense, data is thus everything that is not program code. Generally and in science, data is a gathered body of facts. Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to computers data. Data security also protects data from corruption. However in this article would show a method for encryption text data by java program. It will encrypt is such a way that data could not read in plain text. Whereas Forensic science is a combine science. Scientific Evidence is a part of forensic science. By using the forensic science collecting information and present it on the court. So the meaning of evidence of science representing the understanding of collection information by establishes science. For example to create a DNA profile, following the establish protocol to make a DNA profile. So by testing it thousand times it will give the same result. This is the establish rule of science. When applying this rule in the court then it will call scientific Evidence. In Bangladesh most of the time it is seen that judiciary process is depends on confession based. Justice in the lower court does not depend on Digital forensic rather depend on Confession based. The definition of document is given in Section 3 at Evidence Act, 1872 and it is amended by ICT Act 2006 by Section 87 ,it is said that creating document by electronic is also a document .So any picture or video or audio are electronic document is a document .However for digital evidence based solution in this project using autopsy forensic tools, which will run on Kali Linux Forensic mode. It will generate a report paper and calculates MD5 hash values and confirms the integrity of the data before closing the files. Not all computer offence we can called cybercrime , but if a person created forged certificate or steal computer file , may called it as a Digital Crime .In real space , there are some physical force such as robbery , theft etc. But in Digital crime, there is no physical force, but doing the crime by technology.

An average number of books for a normal library is around 10,000. Finding books in a library is a cumbersome process and time consuming especially in a huge library. Besides, the cost to embed RFID tag on each book is too expensive. To overcome the problem, this paper proposed a solution for finding location of library books. The solution is using i) a smartphone application to navigate location of book, and ii) LED Blinker with Beacon Bluetooth Low Energy (BLE) technology on bookshelf. The case study for this research is Library of Jeneral Tun Ibrahim at Universiti Pertahanan Nasional Malaysia (UPNM) Library. This study also produces a new framework for finding books in libraries. The framework is a proof of concept that can be applied in the smart library system to assists library patrons in finding locations of books.

This paper represents an effective method to enhance colour correction for tongue diagnosis. Colour Correction means exactly that, correcting the colour in image in the post production process. If the task of correcting an image is not in the workflow, it may be missing out on how great the image could look. It is one of the tasks of being a director of photography to get the best image to the colourist that can be. Understanding the camera’s limitation and using that knowledge on set is the first step in getting images that are much easier to correct later in the production workflow. Cameras record three colour responses of Red, Green and Blue (RGB) that are device dependent. In this work, preliminary research on tongue colour correction using polynomial regression algorithm has been implemented on Munsell colour checker for future tongue colour correction and diagnosis. The attained RGB colour space from Munsell Checker image converted to Lab colour space which is device independent colour space based on human visual system that is perceptually uniform. Then, several degrees of polynomial regression method are employed to provide comparative analysis on colour reproduction index to produce good quality of image after colour correction procedure. The experimental outcomes on colour checker show the colour difference is equal to 3.3289, ∆E*ab=3.3289 which is acceptable in digital image colour reproducibility.



Prototyping Digital Tongue Diagnosis System on Roborealm and Raspberry-Pi

In Oriental Medicine, the examination of tongue body contributes to rich information in diagnosing some diseases. The practitioners use tongue body colour and other relevant features to predict the patient’s conditions and disease-oriented state. To reduce the ambiguity and other limitation caused by environment, an automatic tongue acquisition system has been introduced recently to assist the medical practitioner in daily clinical practices. However, most of these acquisition systems are not equipped with the intelligent decision support system to diagnose certain diseases using informative tongue bio-markers. In this paper, automatic tongue diagnosis prototype on Raspberry-pi is proposed to reduce human labour and to promote portability. To integrate with Internet of Things (IOT) technology, tongue image processing analysis including segmentation and colour classification techniques using k-means and Support Vector Machine (SVM) is executed on Raspberry-Pi that is equipped with High Definition (HD) camera via MATLAB Coder platform. This high definition camera will capture the real time image of a patient’s tongue to be segmented and analysed further. It is expected to provide health information that can be used as a pre-diagnosis system based on Oriental Medicine perspectives.



Assessment of Knowledge and Attitude regarding Human Papilloma Virus Vaccination among Preclinical Medical Students in the Malaysian Military University

Aye Aye Mon, Halyna Lugova, Myint Myint Maw



Human papillomavirus (HPV) causes cervical cancer and sexually transmitted infections. Cervical cancer is the third most common malignancy among the women worldwide. The primary tool for prevention of cervical cancer is through the HPV vaccination. Pre-clinical year medical students must have background knowledge about HPV vaccination as they become healthcare providers, who will play an important role in influencing patients’ decision to receive vaccination. If their knowledge on the HPV is low this will result in poor attitude towards its prevention. This study was aimed to determine the knowledge of HPV vaccine and cervical cancer as well as the acceptance of HPV vaccination among pre-clinical year medical students. A descriptive cross sectional study was conducted among 83 pre-clinical year medical students in National Defence University of Malaysia (NDUM). A set of self-administered questionnaire was distributed to the respondents to gather the data. Although almost half of respondents (46.3%) did not know the exact indication for HPV vaccination Most of them perceived that HPV vaccine can protect against the cervical cancer (64.4%) and it is as important as Hepatitis B or Haemophilus influenzae vaccines in Malaysia (54.9%). Substantial proportion of the respondents (47.6%) disagreed that HPV vaccination will diminish the need for annual Pap smear testing. The findings of this study show that being a pre-clinical year student does not warrant good knowledge and prevention of HPV infection. There is a need to obtain more information about HPV vaccination effects on cervical cancer in their medical school teaching and from the social media.
