Encoding model | Advantages | Disadvantages |
|
Microvenus project | Laid the foundation for storing abiotic information in DNA | Being inaccurate and not distinctively decodable |
|
Genesis project | Laid the research work to explore the intricate relationship between biology, belief systems, information technology, dialogical interaction, ethics, and the Internet | Inaccurate as the original sentence was altered during mutation at the presence of ultraviolet light |
|
PCR based encoding models | High security because of the size of the microdots and even if an adversary identifies the microdot it would be extremely difficult without the knowledge of the primer sequence | Insertion of errors in template region making it unmanageable to recover the encoded data Need of the knowledge of primers Widespread experimental obstacles and practical problems Need of PCR Data breakage that could occur in encoding and decoding procedures due to errors of humans |
|
Alignment based encoding models | Independent of Polymerase Chain Reaction Greater speed and lower cost of reading DNA data and lower cost of synthetic DNA Positions of the data breakages that could be identified easily by the alignment results although they were not recoverable | Multiplication of cassettes leads to redundant volumes Parity effects cost a certain volume of data sequence Data recovery rate is fragile and is proportional to data breakage which occurs through DNA deletion of long ranges Sequencing of the entire genome is required to retrieve data There is size limit of the cassette oligonucleotides being used to encode the message. If it increases a certain limit there is a possibility of it to appear by chance in host genome |
|
Rewritable and random access based DNA storage system | Random access to data blocks of DNA which promotes nonlinear access Rewriting capability of information into random locations Cross hybridization problems that are eliminated in this method by prohibiting redundancy of information Being used to store frequently updated data which needs to memorize the editing history | High cost |
|
Next generation digital information storage | Employment of one-bit representation per base High scalability High data storage density Highly reliable Each copy having the capability to correct the errors in the other copy as the errors are almost never coextensive | Cost is unfeasible Time for reading and writing onto DNA is high |
|
Encoding scheme for small text files | High volume data storage density Not needing ample context information for encoding purposes Maximum efficiency of compression Reducing cost factor | Have not proceeded in implementing the biological protocols to insert the sequence in genome of bacteria |
