چکیده

Many studies have been conducted in addressing problem of fragmented JPEG. However, carving fragmented JPEG files are not easy to solve due to the complexity of determining the fragmentation point. In this article, X_myKarvee framework is introduced to address the fragmentation issues that occur in JPEG images. X_myKarve introduce a new technique, deletion by binary search to detect fragmentation point which is used to separate a file into several individual fragments. These fragments are then reassembled with the correct pairs which form a complete and correct image. X_myKarve is tested using various datasets namely DFRWS 2006 and DFRWS 2007. The result shows that X_myKarve is capable of carving over 20% more than myKarve and RevIt for DFRWS 2006 datasets where X_myKarve can carve intertwined fragmented JPEG images completely compared to myKarve and RevIt. X_myKarve is a good alternative for carving fragmented JPEG files intertwined with each other.

Bin-Carver: Automatic recovery of binary executable files

File carving is the process of reassembling files from disk fragments based on the file content in the absence of file system metadata. By leveraging both file header and footer pairs, traditional file carving mainly focuses on document and image files such as PDF and JPEG. With the vast amount of malware code appearing in the wild daily, recovery of binary executable files becomes an important...

Carving Contiguous and Fragmented Files with Object Validation

‘‘File carving’’ reconstructs files based on their content, rather than using metadata that points to the content. Carving is widely used for forensics and data recovery, but no file carvers can automatically reassemble fragmented files. We survey files from more than 300 hard drives acquired on the secondary market and show that the ability to reassemble fragmented files is an important requir...

Improving Generic Non-contiguous File Access for MPI-IO

We present a fundamental improvement of the generic techniques for non-contiguous file access in MPI-IO. The improvement consists in the replacement of the conventional data management algorithms based on a representation of the non-contiguous fileview as a list of 〈offset , length〉 tuples. The improvement is termed listless i/o as it instead makes use of spaceand time-efficient datatype handli...

A capacity estimation technique for JPEG-to-JPEG image watermarking

In JPEG-to-JPEG image watermarking (J2J), the input is a JPEG image file. After watermark embedding, the image is JPEG-compressed such that the output file is also a JPEG file. In this paper, we use the human visual system (HVS) model to estimate the J2J data hiding capacity of JPEG images, or the maximum number of bits that can be embedded in JPEG-compressed images. Watson’s HVS model is modif...
