Abstract
Systems and methods for security hardening of a file in transit and at rest via segmentation, shuffling and multi-key encryption are presented. The method including segmenting at a first computer system a file into a plurality of file segments, and encrypting the plurality of file segments using a plurality of encryption keys in order to generate a corresponding plurality of encrypted file segments, wherein each file segment of the plurality of file segments is encrypted using a respective encryption key of the plurality of encryption keys. Additionally included is bidirectional data transformation of a file by obfuscating at a first computer system digital values of the file in order to generate corresponding obfuscated digital values of the file, wherein the obfuscated digital values of the file retain their contextual integrity and referential integrity.
