The long-term preservation of digital objects has become increasingly relevant. Libraries, public institutions and museums, but also companies are requesting solutions to store their digital files with all relevant contents and attributes for the future. This master thesis makes two contributions to the research in digital preservation. The first attempt is the creation of a testbed which store...

Evidence acquisition is concerned with the collection of evidence from digital devices for subsequent analysis and presentation. It is extremely important that the digital evidence is collected in a forensically-sound manner using acquisition tools that do not affect the integrity of the evidence. This paper describes a forensic acquisition tool that may be used to access files on a live system...

Natural systems studies inspire researchers to develop new algorithmic models to solve complex real-world problems to which traditional approaches. In dentistry the Root Canal Treatment (RCT) is one of the complex problems, where various types of file systems are used for canal cleaning and shaping purpose during RCT, as the canal anatomy is complex, it is difficult to operate with rotary instr...

The framework described in this paper is based on the concept of the digital resource. A digital resource is defined as any servable electronic file, retrieved by a user after a search of NSDL, including text files, pictures, films, animations, audio files, software applications, applets, etc. The resource lifecycle framework describes the various stages in the ‘lifecycle’ of a resource, from t...

In several countries, the possession of files containing child and adolescent pornography is a crime. Law-enforcement officers must be able to detect this type of content at crime scenes. The NuDetective Forensic Tool was developed to assist forensic examiners in the timely identification of such files at crime scenes. NuDetective automatically detects nudity in images and employs other techniq...

Nowadays we all are surrounded by big data. The term ‘Big Data’ itself indicates huge volume, high velocity, variety and veracity i.e. uncertainty of data which gave rise to new difficulties and challenges. Hadoop is a framework which can be used for tremendous data storage and faster processing. It is freely available, easy to use and implement. Big data forensic is one of the challenges of bi...

DiameterJ is an open source image analysis plugin for ImageJ. DiameterJ produces ten files for every image that it analyzes. These files include the images that were analyzed, the data to create histograms of fiber radius, pore size, fiber orientation, and summary statistics, as well as images to check the output of DiameterJ. DiameterJ was validated with 130 in silico-derived, digital, synthet...

Electronic commerce has gained importance over the last years, but only a few digital products can be sold and delivered over the internet. These products need security to be protected against pirates who could sell copies over the internet without any loss of quality. MIDI files are an excellent example for such a product: They are rather small and expensive, making them ideal for downloading ...

The acquisition of data stored on cloud services has become increasingly important to digital forensic investigations. Apple, Inc. continues to expand the capabilities of its cloud service, iCloud. As such, it is critical to determine an effective means for forensic acquisition of data from this service and its effect on the original file data and metadata. This research examined files acquired...

Digitalization of information across organizations has made information exchange between organizations easier. Information exchange, however, requires governmental organizations to define security policies, stating which information can be accessed, processed and indexed by which organizations, when, where and how. Ensuring that the information, once exchanged, stays up-to-date is a real challe...
