Finding Data in DNA: Computer Forensic Investigations of Living Organisms [chapter]

Marc B. Beck, Eric C. Rouchka, Roman V. Yampolskiy
2013 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
Recent advances in genetic engineering have allowed the insertion of artificial DNA strands into the living cells of organisms.  ...  Several methods have been developed to insert information into a DNA sequence for the purpose of data storage, watermarking, or communication of secret messages.  ...  The Huffman code is the most economical in terms of codon length, while the comma code is the least economical. The Clelland coding scheme and the Wong coding scheme are the easiest to implement.  ...

1979 Mathematical Reviews  
Economical encoding of commas between strings. Comm. ACM 21 (1978), no. 4, 315-317.  ...  The idea behind the method is to cleverly encode the lengths of the strings within the sequence. The method has ap- peared in modified forms in earlier papers by J. L. Bentley and A. C.  ... 

The Use and Usefulness of Numeration Systems [chapter]

Stabilizing synthetic data in the DNA of living organisms

Nozomu Yachie, Yoshiaki Ohashi, Masaru Tomita
2008 Journal of Systems and Synthetic Biology  
Data-encoding synthetic DNA, inserted into the genome of a living organism, is thought to be more robust than the current media.  ...  A disadvantage of this approach is that encoded data can be unexpectedly broken by mutation, deletion, and insertion of DNA, which occurs naturally during evolution and prolongation, or laboratory experiments  ...  Kazuharu Arakawa for useful suggestions in the preparation of the manuscript.  ...

Robust universal complete codes for transmission and compression

Aviezri S. Fraenkel, Shmuel T. Kleinb
1996 Discrete Applied Mathematics  
Several measures are defined and investigated, which allow the comparison of codes as to their robustness against errors.  ...  Then new universal and complete sequences of variable-length codewords are proposed, based on representing the integers in a binary Fibonacci numeration system.  ...  Although for the same input S, the string C'(S) encoded by C' will be longer than the string H(S) encoded by Huffman's algorithm, the number of codewords in C' (S) , which is the number of times we have  ...

Overflow/underflow-free floating-point number representations with self-delimiting variable-length exponent field

H. Yokoo
1992 IEEE transactions on computers  
A class of new floating-point representations of real numbers, based on representations of the integers is described.  ...  In the class, every representation uses a self-delimiting representation of the integers as a variable length field of exponent, and neither overflow nor underflow appears in practice.  ...  Iri of the University of Tokyo for his continued interest and encouragement.  ...
