the main purpose of this paper is identifying the current situation of iranian digital libraries in terms of interoperability abilities and proposing an interoperability solution for iranian digital libraries. analytical survey is used in this research. in fact, questionnaire and observation were used for collecting data about the current situation of iranian digital library applications. the g...

Graphic design applications are often used for the editing and design of digital art. The same applications can be used for creating counterfeit documents like identity documents (IDs), driver’s licenses or passports among others. However the use of any graphic design application leaves behind traces of digital information which can be used during a digital forensic investigation. Current digit...

File carving is a popular method used for digital investigations for detecting the presence of specific target files on digital media. Hash based sector hashing helps to identify the presence of a target file. The hashes of physical sectors of the media is compared to the database of hashes created by hashing every block of the target files. To enable this, instead of evaluating the hashes of e...

Digital Image Watermarking used for protecting digital media files and data. It has been an active research field since last decades. Digital Image watermarking is an approach that enables a user from being misused of personal images or information. Here, the term “watermarking” refer to data hiding for copyright protection and image security. Digital Watermarking is becoming a necessity these ...

The digital content lifecycle is generally understood as a set of activities: select, get and/or produce, prepare and/or assemble, describe, manage, and, as appropriate, make available. At the bit level, digital content is viewed as files on a file system. Many crucial activities of the digital content lifecycle are therefore undertaken primarily at the bit level, including transferring, moving...

This paper describes a digital forensic model for investigating computer networks, focusing specifically on network log mining. A thorough examination of log files is needed to reveal the hidden actions of criminals in computer networks. The proposed model specifies the steps that forensic investigators can follow with regard to the extraction and examination of digital evidence from log files ...

The Photo Response Non-Uniformity acts as a digital fingerprint that can be used to identify image sensors. This characteristic has been used in previous research to identify scanners, digital photo cameras and digital video cameras. In this paper we use a wavelet filter from Lukáš et al [1] to extract the PRNU patterns from multiply compressed low resolution video files originating from webcam...

Previously [1], we demonstrated a method for automated search for query-identical images and their differentiation from the query image closest analogs, based on the previously described nonprobabilistic method for hypothesis generation and verification (HyGV-2D) [2-3] applied to analysis of grayscale (or color) histograms. The HyGV method provides the differentiation between original images an...

Digital camcorders commonly have an in-built capability to export entire video files or a single image to storage media such as a digital versatile disc (DVD). In the event that a DVD is not properly finalised, its contents might not be easily readable. It is generally accepted that recovering video evidence from an unfinalised DVD in a forensically sound manner is an expensive and a challengin...

The impacts of information and communication technologies (ICT) on the environment have been a rich area for research in recent years. ICT has substantially affected commerce, enabling new methods for connecting producers and consumers (i.e., e-commerce) and creating new electronic products. A prime example is the continuing rise of digital music delivery, which has obvious potential for reduci...
