Digital Libraries (DLs) is a recent term used to refer to video files used in a shared space. Fox and his colleagues information systems (IS) and services that provide elec(1995) noted these kinds of conceptual differences when tronic documents—text files, digital sound, digital they observed: video—available in dynamic or archival repositories. Some insist that DLs refer to documentary collect...

Information transmission is increasing with grow of using WEB. So, information security has become very important. Security of data and information is the major task for scientists and political and military people. One of the most secure methods is embedding data (steganography) in different media like text, audio, digital images. This paper presents two experiments in steganography of digital...

The majority of existing digital preservation solutions are focusing on the long-term storage of digital content such as documents, images, video, audio files and other domain specific data. Preservation of an Information Technology infrastructure for supporting business processes is a much more challenging task. It requires the preservation of software and hardware stacks as well as relevant c...

Current research on music information retrieval and music digital libraries focuses on providing access to huge, public music collections. In this paper we consider a different, but related, problem: supporting an individual in maintaining and using a personal music collection. We analyze organization and access techniques used to manage personal music collections (primarily CDs and MP3 files),...

Digital government applications often involve web sites to provide information for citizens and visitors from essential services such as passport application or motor vehicle registration to discretionary, but highly popular applications such as recreation and parks information. Another aspect of government web sites is the delivery of statistical reports with summary tables, aggregated data re...

For digital forensics, eliminating the uninteresting is often more critical than finding the interesting since there is so much more of it. Published software-file hash values like those of the National Software Reference Library (NSRL) have limited scope. We discuss methods based on analysis of file context using the metadata of a large corpus. Tests were done with an international corpus of 2...

INTRODUCTION We describe initial validation of a new system for digital to analog conversion (DAC) and reconstruction of 12-lead ECGs. The system utilizes an open and optimized software format with a commensurately optimized DAC hardware configuration to accurately reproduce, from digital files, the original analog electrocardiographic signals of previously instrumented patients. By doing so, t...

Digital watermarking plays an increasingly important role for proving authenticity and copyright protection. The Internet is an ideal medium for selling digital goods it also makes redistribution of pirated files very easy. Digital watermarking can be used to insert invisible data into an object helping to track down pirate copies and to prove rightful ownership in a dispute. In this paper we p...

Permanence issues for digital photographs arise in three different areas. First, the materials used for digital hard copies should preferably be as permanent as the conventional photographic materials. Longevity of digital hard copy materials is affected by the stability of the material and the storage conditions. Secondly, the digital files that are the counterpart of the conventional negative...
