DNA Camouflage for the Protection of Sequence Identity from Unauthorized Individuals

The amount of digital information produced is continually growing, whereas digital space is increasingly vulnerable. DNA has emerged as a potential medium for information storage due to its high density, security (e.g., cannot be accessed remotely, requires technical skill to manipulate), stability, and reproducibility. Furthermore, valuable technological assets (e.g. biotherapeutic sequences) are stored in DNA and are thus vulnerable to industrial theft. DNA camouflage provides an additional layer of security to shield encoded information from unauthorized parties, both digitally encoded information and genetic information.
Patent Abstract: 
DNA camouflage is a method to obscure DNA sequence identity from unauthorized individuals. The system has two components: 1) the “camouflaged” DNA sequence flanked by recognition sites of recombinases, and 2) a cell that expresses the aforementioned recombinases. When the flanked DNA sequence (1) is introduced into the recombinase-expressing cell (2), the recombinases bind their recognition sites and invert or excise the sandwiched fragment. Bidirectional recombinases (e.g., FLP and Cre), which bind identical recognition sites (e.g., FRT and loxP, respectively), can be used to induce reversible combination. This causes the sequences to oscillate between two states (or more, if multiple recombinase systems are used), while the embedded data remains unchanged. An unauthorized attempt to sequence this mixed population would yield a low-quality, incomprehensible readout. Camouflaging sequences introduces complexity without altering the stored information, rendering the method useful for the protection of any valuable and safeguarded genetic or DNA encoded material.
