Capacity of DNA Data Embedding Under Substitution Mutations

Balado, Félix (IEEE, 2013-02)

A number of methods have been proposed over the last decade for encoding information using deoxyribonucleic acid (DNA), giving rise to the emerging area of DNA data embedding. Since a DNA sequence is conceptually ...
Gene Tagging and the Data Hiding Rate

Balado, Félix ; Haughton, David (The Institution of Engineering and Technology, 2012-06-28)

We analyze the maximum number of ways in which one can intrinsically tag a very particular kind of digital asset: a gene, which is just a DNA sequence that encodes a protein. We consider gene tagging under the most ...
Genetic channel capacity revisited

Balado, Félix (Springer, 2011-12)

We revisit previous analyses on the computation of the maximum mutual information between a genetic sequence and its mutated versions down the generations, taking into account the protein translation mechanism of the genetic ...
A Modified Watermark Synchronisation Code for Robust Embedding of Data in DNA

Haughton, David ; Balado, Félix (IEEE, 2013-05-26)

DNA data embedding is a newly emerging field aspiring to encode data in deoxyribonucleic acid (DNA). DNA is an inherently digital and noisy medium, undergoing substitution, insertion and deletion mutations. Hence, ...
On the embedding capacity of DNA strands under insertion, deletion and substitution mutations

Balado, Félix (SPIE--The International Society for Optical Engineering, 2010-01)

A number of methods have been proposed over the last decade for embedding information within deoxyribonucleic acid (DNA). Since a DNA sequence is conceptually equivalent to a unidimensional digital signal, DNA data embedding ...
On the Shannon capacity of DNA data embedding

Balado, Félix (IEEE, 2010-03-14)

This paper firstly gives a brief overview of information embedding in deoxyribonucleic acid (DNA) sequences and its applications. DNA data embedding can be considered as a particular case of communications with or without ...
Performance of DNA data embedding algorithms under substitution mutations

Haughton, David ; Balado, Félix (2010-12)

DNA data embedding is a relatively recent area which aims at embedding arbitrary information in deoxyribonucleic acid (DNA) strands. One interesting application of DNA data embedding can be tracing pathways of genetic ...
Permutation Codes and Steganography

Balado, Félix ; Haughton, David (IEEE, 2013-05-26)

We show that Slepian’s Variant I permutation codes implement first-order perfect steganography (i.e., histogram-preserving steganography). We give theoretical expressions for the embedding distortion, embedding rate and ...
Repetition coding as an effective error correction code for embedding information in DNA

Haughton, David ; Balado, Félix (IEEE, 2011-10-24)

The goal of DNA data embedding is to enable robust encoding of non-genetic information in DNA. This field straddles the areas of bioinformatics and digital communications, since DNA mutations can be seen as akin to a noisy ...
