| Summary: | There are a lot of information embedded in JPEG image than just
graphics. Visualization of its metadata would benefit digital forensic investigator
to view embedded data including corrupted image where no graphics can be
displayed in order to assist in evidence collection for cases such as child pornography
or steganography. There are already available tools such as metadata
readers, editors and extraction tools but mostly focusing on visualizing attribute
information of JPEG Exif. However, none have been done to visualize metadata
by consolidating markers summary, header structure, Huffman table and quantization
table in a single program. In this paper, metadata visualization is done
by developing a program that able to summarize all existing markers, header
structure, Huffman table and quantization table in JPEG. The result shows that
visualization of metadata helps viewing the hidden information within JPEG
more easily. |
