Fuzzy Dataset Processing and Biometric Identity Technology Leveraging Blockchain Ledger Technology

A computer system, comprising:

• a processor;
• a memory device coupled to the processor;
• and
• a computer readable storage device coupled to the processor, wherein the storage device contains program code executable by the processor via the memory device to implement a method for verifying that distorted biometric information received by a computing device is authentic, the method comprising:
• receiving a signal indicative of a distorted biometric of a biometric of a person;
• determining, by a processor, a DNA sequence code of the signal indicative of the distorted biometric signal;
• generating, by the processor, a first dataset based on the DNA sequence code;
• hashing, by the processor, the first dataset to obtain a second dataset, wherein a relationship of data values and ranges of the first dataset and the second dataset are maintained;
• encrypting, by the processor, the second dataset;
• storing the encrypted second dataset into a blockchain to generate a blockchain transaction that includes one or more biometric identifiers;
• publishing, by the processor, the generated blockchain transaction to a distributed blockchain computing system for authentication;
• retrieving, by the processor, the encrypted second dataset from the blockchain;
• decrypting, by the processor, the encrypted second dataset to obtain the second dataset to authenticate that the blockchain has validated the submitted blockchain transaction that includes one or more biometric identifiers;
• comparing, by the processor, the second dataset to a test dataset to determine if the second and test datasets are from a related data source and remains unchanged from the distorted biometric of the person;
• and
• responsive to a validation, updating, by the processor, a new transaction record on the blockchain to indicate that the submitted blockchain transaction has been validated.
