Data leak protection system and processing methods thereof

A method of identifying data leaks in a messaging gateway implemented at least in part on a message processing device, comprising:

• identifying one or more asset within a data package via an asset descriptor,
• framing the one or more assets identified into a contextual environment that is derived from a unique context based on the data package;
• and
• identifying a data perimeter via a domain identifier that is both specific and adaptable to the one or more assets and the contextual environment for the one or more assets based on the contextual environment identified;
• generating a digital fingerprint for the data package based on the one or more assets identified, the contextual environment, and the data perimeter;
• comparing the digital fingerprint to a collection of domain specific identifiers, each domain specific identifier characterizing the digital fingerprint within the domain;
• and
• triggering a data leak notification in response to a digital fingerprint that indicates the data package falls outside of the data perimeter for the contextual environment.

• generating a contextual fingerprint for the data package based on the one or more assets identified, the contextual environment, and the data perimeter, the contextual fingerprint being further incorporated into the digital fingerprint;
• comparing the digital fingerprint to a collection of domain specific identifiers, each domain specific identifier characterizing the digital fingerprint within the domain, wherein the collection of domain specific identifiers is refined based on the comparison of the digital fingerprint to the collection of domain specific identifiers;
• and
• triggering a data leak notification in response to a digital fingerprint that indicates the data package falls outside of the data perimeter for the contextual environment, wherein triggering a data leak notification in response to a digital fingerprint that indicates the data package falls outside of the data perimeter for the contextual environment includes quarantining the data package for manual processing based on the triggered data leak notification.
