Obfuscation of JPEG CODEC IP core for CE devices
Joint Picture Export Group (JPEG) is the most commonly used image compression standard in the world. One cannot comprehend a CE system that does not process a JPEG. Without JPEG there is no smartphone photography, no social media. So, authors feel strongly that this important multimedia core “JPEG”needs to give well-deserving credit in terms of securing it when security/protection of “DSP core”has been a major focus of all the discussions in this book so far. The chapter is organized as follows: Section 9.2 provides an overview of DCT-based JPEG compression and decompression process. Section 9.3 explains the design process of generating structurally obfuscated JPEG CODEC IP core; Section 9.4 provides a detailed insight on the implementation process of obfuscated JPEG codec IP core in a CAD synthesis tool. Section 9.5 provides implementation and analysis of JPEG CODEC IP core as well as compressed images through the devised JPEG CODEC IP core.
