Digital evidence bags

This thesis analyses the traditional approach and methodology used to conduct digital forensic information capture, analysis and investigation. The predominant toolsets and utilities that are used and the features that they provide are reviewed. This is used to highlight the difficulties that are encountered due to both technological advances and the methodologies employed. It is suggested that these difficulties are compounded by the archaic methods and proprietary formats that are used. An alternative framework for the capture and storage of information used in digital forensics is defined named the `Digital Evidence Bag' (DEB). A DEB is a universal extensible container for the storage of digital information acquired from any digital source. The format of which can be manipulated to meet the requirements of the particular information that is to be stored. The format definition is extensible thereby allowing it to encompass new sources of data, cryptographic and compression algorithms and protocols as developed, whilst also providing the flexibility for some degree of backwards compatibility as the format develops. The DEB framework utilises terminology to define its various components that are analogous with evidence bags, tags and seals used for traditional physical evidence storage and continuity. This is crucial for ensuring that the functionality provided by each component is comprehensible by the general public, judiciary and law enforcement personnel without detracting or obscuring the evidential information contained within. Furthermore, information can be acquired from a dynamic or more traditional static environment and from a disparate range of digital devices. The flexibility of the DEB framework permits selective and/or intelligent acquisition methods to be employed together with enhanced provenance and continuity audit trails to be recorded. Evidential integrity is assured using accepted cryptographic techniques and algorithms. The DEB framework is implemented in a number of tool demonstrators and applied to a number of typical scenarios that illustrate the flexibility of the DEB framework and format. The DEB framework has also formed the basis of a patent application

Computer forensics methodology and praxis.

This thesis lays the groundwork for creation of a graduate-level computer forensics course. It begins with an introduction explaining how computing has invaded modern life and explains what computer forensics is and its necessity. The thesis then argues why universities need to be at the forefront of educating students in the science of computer forensics as opposed to proprietary education courses and the benefits to law enforcement agencies of having a computer scientist perform forensic analyses. It continues to detail what computer forensics is and is not. The thesis then addresses legal issues and the motivation for the topic. Following this section is a review of current literature pertaining to the topic. The last half of the thesis lays a groundwork for design of a computer forensics course at the graduate level by detailing a methodology to implement which contains associated laboratory praxis for the students to follow

Towards a circular economy: fabrication and characterization of biodegradable plates from sugarcane waste

Bagasse pulp is a promising material to produce biodegradable plates. Bagasse is the fibrous residue that remains after sugarcane stalks are crushed to extract their juice. It is a renewable resource and is widely available in many countries, making it an attractive alternative to traditional plastic plates. Recent research has shown that biodegradable plates made from Bagasse pulp have several advantages over traditional plastic plates. For example, they are more environmentally friendly because they are made from renewable resources and can be composted after use. Additionally, they are safer for human health because they do not contain harmful chemicals that can leach into food. The production process for Bagasse pulp plates is also relatively simple and cost-effective. Bagasse is first collected and then processed to remove impurities and extract the pulp. The pulp is then molded into the desired shape and dried to form a sturdy plate. Overall, biodegradable plates made from Bagasse pulp are a promising alternative to traditional plastic plates. They are environmentally friendly, safe for human health, and cost-effective to produce. As such, they have the potential to play an important role in reducing plastic waste and promoting sustainable practices. Over the years, the world was not paying strict attention to the impact of rapid growth in plastic use. As a result, uncontrollable volumes of plastic garbage have been released into the environment. Half of all plastic garbage generated worldwide is made up of packaging materials. The purpose of this article is to offer an alternative by creating bioplastic goods that can be produced in various shapes and sizes across various sectors, including food packaging, single-use tableware, and crafts. Products made from bagasse help address the issue of plastic pollution. To find the optimum option for creating bagasse-based biodegradable dinnerware in Egypt and throughout the world, researchers tested various scenarios. The findings show that bagasse pulp may replace plastics in biodegradable packaging. As a result of this value-added utilization of natural fibers, less waste and less of it ends up in landfills. The practical significance of this study is to help advance low-carbon economic solutions and to produce secure bioplastic materials that can replace Styrofoam in tableware and food packaging production
