Hash-based carving is a technique for detecting the presence of specific “target files” on digital media by evaluating the hashes of individual data blocks, rather than the hashes of entire files. Unlike whole-file hashing, hash-based carving can identify files that are fragmented, files that are incomplete, or files that have been partially modified. Previous efforts at hash-based carving have...

There have been many reports on the construction of digital libraries. We find three shortcomings in many of these reports. (1) They fail to articulate the organizational need for a digital library. (2) They ignore the important operational details in establishing the library, including the end user classroom. (3) They fail to provide any quantitative data concerning the ability of the digital ...

The swift progression in internet networking services has led to massive growth in various multimedia applications such as images, audio files, video files etc. This web revolution has made it feasible and simpler to transmit digital media from one point to another with paramount speed and accuracy. Besides this, it is easier to misuse and exploit the valuable information through hacking at the...

In digital signal processing, bit width of intermediate variables should be longer than that of input and output variables in order to execute intermediate operations with high precision. Then a processor core for digital signal processing is required to have two types of register files, one of which is used by input and output variables and the other one is used by intermediate variables. This...

This in vitro study compared conventional and digital radiographic linear measurements to determine the working length (WL) of curved canals with fine endodontic files. In total, 30 mesiobuccal root canals in molars were measured with a #06 K-file to a length 1 mm short of the apical foramen (WL1). Teeth were mounted in plastic blocks and standardized periapical radiographs were obtained by con...

Digital piracy, the sharing files of music on peer-to-peer (P2P) networks has been cited as the key threat to the music industry by distorting promoting plans of albums (Billboard.biz, 2009). To combat widespread digital piracy on file-sharing networks, the content industries have employed diverse anti-piracy strategies including pollution technologies and stronger copyright legislation for mus...

In digital steganography normally image, audio or video files are the standard cover files or the host files for embedding secret message such as text, image, audio or video. Nath et al.(2) explored the standard method for hiding secret message inside standard cover files such as image, audio or video files. In the present work we have shown how we can hide secret message in encrypted form in s...

With technology of digital image recognition, the data frames include vehicle’s digital image can be detected automatically from an Audio Video Interleaved (AVI) File, and vehicle type will be recognized automatically. The system consists of four modules: Reading AVI file and decomposing it into digital image frames; Motion detection; Vehicle’s digital image processing; Module of vehicle type c...
