US 12,505,232 B2 · System and method facilitating encryption preserving format as a distributed processing library

Abstract

The present invention provides a robust and effective solution to an organization by enabling them to implement a system (110) for facilitating format preserving encryption capability such that the encrypted data will not be available with its original value in a big data system and render sensitive field data as non-sensitive. Thus, sensitive data may be hidden from data-stores/warehouses without worrying about downstream access to the data. The system (110) proposed may also preserve the data type and format of datasets but not limited to the like. The system encrypts a dataset with a unique key (404) and then allows a privileged user (902) to decrypt the encrypted dataset with the unique key (404) and view the decrypted values without getting access to the sensitive original dataset.

Dependent claims

A system for facilitating encryption preservation format as a distributed processing library, the system comprising:

a processor;
and
a memory coupled to the processor, wherein the memory comprises processor-executable instructions, which on execution, causes the processor to:
receive a set of data packets comprising decimal numbers, multi-lingual alphabets, and alphanumeric values from a database;
extract an original dataset from the received set of data packets for encryption of the original dataset in the database;
encrypt the extracted original dataset by using a Format Preserving Encryption (FPE) technique to generate an encrypted dataset of a same format and a same length associated with the original dataset in the database and in a database of fast accessibility;
and
provide an interface to a user to access the encrypted dataset for a regeneration of the original dataset from the encrypted dataset.
