NON-DECRYPTABLE DATA ENCRYPTION TECHNIQUE FOR A SCALABLE DATA-RELATED OPERATION

1 . A method for non-decryptably encrypting data entries, the method comprising:

receiving or accessing, at a first computing system, an input file, the input file comprising a list of data entries;

generating an initialization vector for a data entry;

generating a fingerprint for the data entry;

generating an encryption signature based on the initialization vector and the fingerprint;

determining an encryption type for the data entry;

generating, using the encryption type, an encryption value for the data entry; and

producing, at the first computing system, an output file comprising the encryption value and the encryption signature, wherein the encryption value cannot be decrypted to produce the data entry.

2 . The method of claim 1 , wherein the fingerprint is for controlling division of the list of data entries into blocks of data entries, wherein the fingerprint is used for a single data session or multiple data sessions.

3 . The method of claim 1 , wherein a size of the list of data entries is greater than a size of a memory of the first computing system.

4 . The method of claim 1 , wherein the output file is produced in a memory of the first computing system.

5 . The method of claim 1 , further comprising prior to generating the encryption value, normalizing the data entry, the normalizing comprising at least one of modifying a character of the data entry, deleting the character of the data entry, or adding a new character to the data entry.

6 . The method of claim 1 , further comprising determining a second encryption type for a second normalized data entry from the list of data entries, and inserting a new data entry in the output file for determining a false positive match with the new data entry.

7 . The method of claim 1 , further comprising binding the fingerprint and the initialization vector the data entry using a lambda calculus operation.

8 . The method of claim 1 , further comprising sorting encryption values in the output file such that an order of the encryption values does not have one-to-one correspondence with an order of the list of data entries.

9 . The method of claim 1 , further comprising transmitting the output file to a second computing system.

10 . The method of claim 9 , wherein a second computing system:

receives the output file from the first computing system, the output file comprising the encryption value;

receives or accesses a second input file, the second input file comprising a second list of data entries;

determines the fingerprint from the output file.

11 . The method of claim 10 , wherein a second computing system:

identifies, using the fingerprint, a subset of the second list of data entries in the second input file, the subset of the second list of data entries comprising a second data entry;

generates, using the encryption type, a second encryption value for the second data entry;

compares the encryption value with the second encryption value;

determines whether the encryption value matches the second encryption value;

in response to determining the encryption value matches the second encryption value, removes the second encryption value from the second output file or the output file to produce a modified second output file or a modified output file; and

transmits the modified output file or the modified second output file.

12 . The method of claim 11 , wherein a size of the subset of the second list of data entries is equal to or less than a memory of the second computing system.

13 . The method of claim 11 , wherein a size of the second list of data entries or the output file is greater than a memory of the second computing system.

14 . The method of claim 10 , wherein the second computing system:

generates, using the encryption type, a second encryption value for a second data entry in the second input file;

compares the encryption value with the second encryption value;

determines whether the encryption value matches the second encryption value;

in response to determining the encryption value matches the second encryption value, removes the second encryption value from the second output file or the output file to produce a modified second output file or a modified output file; and

transmits the modified output file or the modified second output file.

15 . The method of claim 14 , wherein the second computing system, prior to transmitting the modified output file or the modified second output file, inserts a second encryption signature in the modified output file or the modified second output file.

16 . The method of claim 14 , further comprising:

receiving the modified output file or the modified second output file from the second computing system;

determining, using the modified output file or the modified second output file, the initialization vector;

re-receiving or re-accessing the input file;

re-generating, using the encryption type, a third encryption value for a data entry in the input file; and

comparing the third encryption value to a fourth encryption value in the modified output file or the modified second output file.

17 . The method of claim 16 , further comprising:

in response to determining the third encryption value does not match the fourth encryption value, retaining the third encryption value;

determining a second data entry associated with the third encryption value; and

producing a second output file comprising the second data entry.

18 . The method of claim 16 , further comprising deleting the encryption signature from the modified output file.

19 . The method of claim 16 , wherein determining the initialization vector comprises:

determining the fingerprint;

building a fingerprint table using the fingerprint; and

merging the modified output file or the second modified output file with the fingerprint table.

20 . A computing system for non-decryptably encrypting data entries, the computing system for:

receiving or accessing an input file, the input file comprising a list of data entries;

generating an initialization vector for a data entry;

generating a fingerprint for the data entry;

generating an encryption signature based on the initialization vector and the fingerprint, the encryption signature being associated with a data session;

determining an encryption type for the data entry;

generating, using the encryption type, an encryption value for the data entry; and

producing an output file comprising the encryption value and the encryption signature, wherein the encryption value cannot be decrypted to produce the data entry.
