Method and system for format preserving of dates

A system for format preserving tokenization of calendar dates in data suitable for use in a data-centric ecosystem for safeguarding and securing data as it moves from networks to applications and a cloud, the system comprising:

• a Computer Agent with centrally defined global parameters in a global protection policy;
• and
• one or more Connectors communicatively coupled to the Computer Agent for managing and distributing the global protection policy to the one or more Connectors that convert and store non-sensitive token date data on a hard disk, wherein said one or more Connectors performs steps for:
• reading said global parameters from the global protection policy;
• generating a date look-up table using said global parameters;
• shuffling said date look-up table by way of a quick unsort to ensure secrecy and produce a shuffled date look-up table;
• and selectively:
• tokenizing date entries of sensitive date data via said shuffled date look-up table to produce said non-sensitive token date data, wherein said tokenizing comprises:
• retrieving a date format, a date range, an encryption key and a tweak value from said global parameters in the global protection policy;
• generating said date lookup table with all possible dates in said date format in the date range;
• seeding a Random Number Generator with said date range, said encryption key and said tweak to produce a seeded RNG;
• and
• shuffling said date lookup table in accordance with an output of said Random Number Generator;
• and
• detokenizing said non-sensitive token date data via said shuffled date look-up table to produce said date entries of the sensitive date data, wherein said data look-up table and shuffled date look-up table are pinned in system memory and not stored on said hard disk, and encrypted with a key unique to each installation of said one or more Connectors, wherein said Computer Agent and one or more Connectors comprise one or more processors and memory coupled to the one or more processors, wherein the memory includes one or more partitions and computer instructions which when executed by the one or more processors causes the one or more processors to perform said steps and operations.
