Oligonucleotides representing digital data

A computer system for creating an oligonucleotide sequence to represent digital data, the computer system comprising:

• data memory to store a first set of multiple oligonucleotide sequences;
• and
• a processor configured to:
• select from the first set of multiple oligonucleotide sequences one oligonucleotide sequence for each of multiple parts of the data, the multiple oligonucleotide sequences being configured to generate an electric time-domain signal from one oligonucleotide sequence that is distinguishable from the electric time-domain signal from another oligonucleotide sequence, the electric time-domain signal being indicative of an electric characteristic of one or more nucleotides present in an electric sensor at any one point in time;
• and
• combine the one oligonucleotide sequence for each of multiple parts of the data into a single oligonucleotide sequence that represents a single oligonucleotide molecule to encode the digital data.

A method for manufacturing an identifiable product, the method comprising:

• manufacturing the product;
• selecting from a first set of multiple oligonucleotide sequences one oligonucleotide sequence for each of multiple parts of digital identification data, the multiple oligonucleotide sequences being configured to generate an electric time-domain signal from one oligonucleotide sequence that is distinguishable from the electric time-domain signal from another oligonucleotide sequence, the electric time-domain signal being indicative of an electric characteristic of one or more nucleotides present in an electric sensor at any one point in time;
• and
• combining the one oligonucleotide sequence for each of multiple parts of the data into a single oligonucleotide sequence that represents a single oligonucleotide molecule to encode the digital identification data;
• synthesising the oligonucleotide molecule;
• and
• adding the synthesised oligonucleotide sequence to the product to allow decoding the digital identification data to verify the product's identity.

A method of verifying a product's identity, the method comprising:

• providing a product to which a oligonucleotide molecule has been added,
• obtaining an electrical signal indicative of a sequence of the oligonucleotide molecule;
• selecting from a first set of multiple oligonucleotide sequences one oligonucleotide sequence for each of multiple parts of the electrical signal, the multiple oligonucleotide sequences being configured to generate an electric time-domain signal from one oligonucleotide sequence that is distinguishable from the electric time-domain signal from another oligonucleotide sequence, the electric time-domain signal being indicative of an electric characteristic of one or more nucleotides present in an electric sensor at any one point in time;
• and
• decoding digital data encoded by the multiple oligonucleotide sequences to verify the product's identity based on the decoded digital data.

An identifiable product comprising:

• one or more product constituents;
• and
• a synthesised oligonucleotide molecule added to the one or more product constituents, wherein
• the synthesised oligonucleotide molecule is represented by a single oligonucleotide sequence,
• the single oligonucleotide sequence is a combination of oligonucleotide sequences comprising one oligonucleotide sequence selected for each of multiple parts of digital data from a first set of multiple oligonucleotide sequences to encode the digital data,
• the multiple oligonucleotide sequences being configured to generate an electric time-domain signal from one oligonucleotide sequence that is distinguishable from the electric time-domain signal from another oligonucleotide sequence, the electric time-domain signal being indicative of an electric characteristic of one or more nucleotides present in an electric sensor at any one point in time;
• and
• the digital data allows verification of the product's identity from decoding the digital data from the synthesised oligonucleotide molecule.
