Comparison of the performance of cDNA secret writing techniques.

Features	DNA hybridization technique	Chromosome DNA indexing
Running time	Less	More
Size of the key	Large depending on the input	Large independent of the input
Strength of the algorithm	High based on the type, size, and the randomness of the key	High based on the key type and key size and the randomly produced index
Memory space	Needs more memory space for storing the lengthy key and performing the operations involving it	More than the hybridization type because of the huge key length and the index array involved
Cost	High	High
Longevity	Believed to withstand any duration	Believed to withstand any duration
