Because files are typically stored as sequences of data blocks, the file carving process in digital forensics involves the identification and collocation of the original blocks of files. Current file carving techniques that use the signatures of file headers and footers could be improved by first classifying each data block in the storage media as belonging to a given file type. Unfortunately, ...

This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and s...

Small Web Format (SWF) or Flash files are widely used on the Internet to provide Rich Internet Applications (RIAs). This makes SWF files an excellent candidate for disseminating hidden data. However, digital forensic investigators are unable to detect and extract the hidden data because limited information is available about the techniques used to hide data in SWF files. This paper investigates...

The widespread use of server and desktop virtualization technologies increases the likelihood of unauthorized and uncontrolled distribution of virtual machine (VM) images that contain proprietary software. This paper attempts to address this issue using a platform-independent digital watermarking scheme applicable to a variety of VM images. The scheme embeds a watermark in the form of files in ...

In this paper, we propose effective system for digital music retrieval. We divided proposed system into Client and Server. Client part consists of pre-processing and Content-based feature extraction stages. In pre-processing stage, we minimized Time code Gap that is occurred among same music contents. As content-based feature, first-order differentiated MFCC were used. These presented approxima...

Nowadays digital libraries have become the source of information, sharing across the globe in the fields of education, research and knowledge. The full usage of digital libraries will be realized only when people can have access to the material from any location. The advantage of multimedia is that people of all ages can understand more clearly by seeing or hearing rather than reading. Consider...

Journaling is a relatively new feature of modern file systems that is not yet exploited by most digital forensic tools. A file system journal caches data to be written to the file system to ensure that it is not lost in the event of a power loss or system malfunction. Analysis of journal data can identify which files were overwritten recently. Indeed, under the right circumstances, analyzing a ...

Applications are no longer monolithic files, but rather a collection of dynamically linked libraries, images, fonts, etc. For such applications to function correctly, all of the required files must be available and be the correct version. Missing files preclude application execution, and incorrect versions lead to mysterious and frustrating failures. This paper describes a simple scheme to addr...

Computer forensics is emerging as an important tool in the fight against crime. Increasingly, computers are being used to facilitate new criminal activity, or used in the commission of existing crimes. The networked world has seen increases in, and the volume of, information that may be shared amongst hosts. This has given rise to major concerns over paedophile activity, and in particular the s...
