Dual-Byte-Marker Algorithm for Detecting JFIF Header
نویسندگان
چکیده
The use of efficient algorithm to detect JPEG file is vital to reduce time taken for analyzing ever increasing data in hard drive or physical memory. In previous paper we proposed single-byte-marker algorithm for header detection. In this paper, we propose a novel algorithm so-called dual-byte-marker for header detection. It is based on a newly proposed FORHEADER model. Two experiments have been carried out using images from a hard disk and a physical memory. The experiment results show that dual-byte-marker algorithm provides better performance in executing time for header detection as compared to single-byte-marker.

Detecting JFIF Header using FORHEADER
Header and footer are important in digital investigation for JPEG file detection as only 16% of files are fragmented. The use of efficient algorithm to detect them is vital to reduce time taken for analyzing ever increasing data in hard drive or physical memory. Even though there are few applications developed for file carving that rely on header and footer e.g. Foremost, Scalpel; however the a...
متن کاملZero-byte Support for Bidirectional Reliable Mode (R-mode) in Extended Link-Layer Assisted RObust Header Compression (ROHC) Profile
This document defines an additional mode of the link-layer assisted RObust Header Compression (ROHC) profile, also known as the zero-byte profile, beyond the two defined in RFC 3242. Zero-byte header compression exists in order to prevent the single-octet ROHC header from pushing a packet voice stream into the next higher fixed packet size for the radio. It is usable in certain widely deployed ...
متن کاملRFC 3803 Content Duration MIME Header
Time varying media contents, for example, a spoken voice message or a video clip, have an inherent time duration. Many audio and video encodings may include their duration as header information or may allow accurate calculation based on the byte length of the data. However, it may be useful to present the time duration of the content in a MIME header to allow its simple determination without de...
متن کاملImplementation and Evaluation of the Enhanced Header Compression (IPHC) for 6LoWPAN
6LoWPAN defines how to carry IPv6 packets over IEEE 802.15.4 low power wireless or sensor networks. Limited bandwidth, memory and energy resources require a careful application of IPv6 in a LoWPAN. The IEEE 802.15.4 standard defines a maximum frame size of 127 bytes that decreases to 102 bytes considering the header overhead. A further reduction is due to the security, network and transport pro...
متن کاملAn All-MPLS Approach for UMTS 3G Core Networks
In this paper, we present an all-MPLS approach for UMTS 3G core networks. GTP-tunnel has been defined by 3GPP as the transport mechanism for UMTS. For each packet transmission, extra GTP, UDP, and IP headers (40-byte) are required. For short packets, such as VoIP payloads, transmission overhead is very high. Enhanced-GTP was proposed to eliminate the need for a GTP header. Since its operation m...
