System and method for securing digital data by implementing noise injection

Abstract

A system for secure data obfuscation includes a memory storing instructions and a processor executing those instructions. The system receives a request to transmit a text-based digital data record, including authentication credentials, and associates a request identifier with the request. A probability distribution for a set of alphanumeric characters is selected, and unique alphanumeric noise is generated using unique random keys. Noise generation involves identifying text locations within the digital data record using a first unique random key and sampling alphanumeric characters from the probability distribution using a second unique random key, ensuring the number of characters matches the identified locations. The system inserts sampled characters into the identified locations, creating an altered digital data record. The first and second random keys, along with the altered record, are stored in a database. Upon verifying authentication credentials, the system transmits the original record or the altered record if verification fails.
