System and method for securing digital data by implementing noise injection

A method comprising:

• receiving a request to transmit a text-based data record;
• generating unique alphanumeric noise, wherein generating the unique alphanumeric noise comprises:
• based on a first unique random key, randomly generating a set of text locations within the text-based data record using a first random number generator;
• for each text location from the set of text locations:
• generating a random alphanumeric string comprising one or more randomly sampled alphanumeric characters, wherein a number of the one or more randomly sampled alphanumeric characters is randomly selected based on a second unique random key using a second number generator, and wherein each one of the one or more randomly sampled alphanumeric characters is sampled from a probability distribution using a third unique random key;
• and
• inserting into the text-based data record the random alphanumeric string, resulting in an altered text-based data record;
• recording in a database the first, second and third unique random keys and the altered text-based data record referenced by a request identifier;
• verifying using authentication credentials a permission to access the text-based data record;
• transmitting the text-based data record upon successful verification of the authentication credentials;
• and
• transmitting the altered text-based data record upon unsuccessful verification of the authentication credentials.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to:

• receive a request to transmit a text-based data record;
• generate unique alphanumeric noise, wherein generating the unique alphanumeric noise comprises:
• based on a first unique random key, randomly generating a set of text locations within the text-based data record using a first random number generator;
• for each text location from the set of text locations:
• generate a random alphanumeric string comprising one or more randomly sampled alphanumeric characters, wherein a number of the one or more randomly sampled alphanumeric characters is randomly selected based on a second unique random key using a second number generator, and wherein each one of the one or more randomly sampled alphanumeric characters is sampled from a probability distribution using a third unique random key;
• and
• insert into the text-based data record the random alphanumeric string, resulting in an altered text-based data record;
• record in a database the first, second and third unique random keys and the altered text-based data record referenced by a request identifier;
• verify using authentication credentials a permission to access the text-based data record;
• transmit the text-based data record upon successful verification of the authentication credentials;
• and
• transmit the altered text-based data record upon unsuccessful verification of the authentication credentials.
