Crypto-Stego-Real-Time (CSRT) System for Secure Reversible Data Hiding

Table 1

Hardware versus software based implementation of data security.

Software Implementation	Hardware Implementation
Generalized design under PC environment	Customized designed using FPGAs (ES)
Complex Algorithms can be possible	Simplified Algorithms with hardware
Not a Real time solution	Real time solution with hardware
More power requires for PC	Less power required for embedded system
Easy to modify the design	Difficult to modify the design
More area & cannot execute without PC.	Less area & can execute without PC.
Not Portable	Portable
The Cost of PC, OS and language support	Low-cost due to specific hardware involved
Less secured	More secured
Easy to copy the implemented code.	Difficult to copy the implemented hardware.
All operations are sequential	Parallel operations are possible
