Memory Carving in Embedded Devices: Separate the Wheat from the Chaff

A Study of "Wheat" and "Chaff" in Source Code

Natural language is robust against noise. The meaning of many sentences survives the loss of words, sometimes many of them. Some words in a sentence, however, cannot be lost without changing the meaning of the sentence. We call these words “wheat” and the rest “chaff”. The word “not” in the sentence “I do not like rain” is wheat and “do” is chaff. For human understanding of the purpose and beha...

Improved Content Aware Image Retargeting Using Strip Partitioning

Based on rapid upsurge in the demand and usage of electronic media devices such as tablets, smart phones, laptops, personal computers, etc. and its different display specifications including the size and shapes, image retargeting became one of the key components of communication technology and internet. The existing techniques in image resizing cannot save the most valuable information of image...

Volatile Memory Message Carving: A "per process basis" Approach

The pace at which data and information transfer and storage has shifted from PCs to mobile devices is of great concern to the digital forensics community. Android is fast becoming the operating system of choice for these hand-held devices, hence the need to develop better forensic techniques for data recovery cannot be over-emphasized. This thesis analyzes the volatile memory for Motorola Andro...

Embedded Memory Test Strategies and Repair

The demand of self-testing proportionally increases with memory size in System on Chip (SoC). SoC architecture normally occupies the majority of its area by memories. Due to increase in density of embedded memories, there is a need of self-testing mechanism in SoC design. Therefore, this research study focuses on this problem and introduces a smooth solution for self-testing.  In the proposed m...
