Secure DNA-based password

A system comprising a first sequencer, the first sequencer comprising:

• a processor;
• and
• a memory in communication with the processor, the memory containing program instructions that, when executed by the processor, are configured to cause the sequencer to perform a first method, the first method comprising:
• obtaining, a password-length threshold wherein the password-length threshold comprises an integer;
• obtaining, for a first user, a set of nucleotide locations, wherein a number of nucleotide locations in the set is greater than or equal to the integer;
• obtaining a first sample of the user's DNA;
• determining, in the first sample, a nucleotide at each nucleotide location in the set of nucleotide locations, resulting in a first nucleotide-password sequence;
• and
• performing a one-way hashing operation on the first nucleotide-password sequence with a first hashing algorithm, resulting in a first hashed password.

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• receive, from a first sequencer, identification information associated with a first user;
• transmit, to the first sequencer, a set of nucleotide locations and a set of hash information, wherein each nucleotide location is one nucleotide in length;
• receive, from the first sequencer, a first hashed password;
• and
• storing, in a profile for the first user, the set of nucleotide locations, the set of hash information, the identification information, and the hashed password.
