Abstract: Described are various embodiments of a digital data comparison filter, system and method, and applications therefor. In one embodiment, a digital data comparator system comprises two or more transformation engines each having securely stored in association therewith a common key, a common designated comparator threshold number, and a respective identifier; and a reconstitution engine operable to access partial encryption information from each transformation engine and, only upon relating to identical digital data, process each partial encryption information to successfully release the identical digital data.

Abstract: Described are various embodiments of an integrated network appliance and system. In one embodiment, the appliance comprises: a hardware-integrated processing engine operable to implement a trusted network-related resource; an integrated digital data processor operable to execute said processing engine; an integrated data storage resource accessible to said processing engine to implement said trusted network-related resource; an integrated location sensor; and an embedded hardware security module (HSM) hardwired to interface with said hardware-integrated processing engine via a dedicated hardware-isolated communication path, and operable to execute a trusted internal cryptographic process associated with said trusted network-related resource as a function of location data output from said integrated location sensor.

Abstract: Described are various embodiments of a hardware security module, hardwired port interconnection matrix, and embedded communication channel resources operable on selected hardware port-specific data communicated via this matrix.

Abstract: Described are various embodiments of a machine executable code deployment method and system. In one such embodiment, a machine executable code deployment method is described to comprise: compiling machine readable code in a secure digital processing environment to produce a unique ephemeral machine executable code instance representative thereof; deploying the unique ephemeral machine executable code instance to a distinct digital processing environment to be executed thereon for a predetermined runtime period, wherein execution of the unique ephemeral machine executable code instance is automatically terminated after the predetermined runtime period; and repeating the deploying for subsequent unique ephemeral machine executable code instances.

Abstract: Described are various embodiments of a hardware security module. For example, in one embodiment, a hardware security module is described to comprise: two or more hardware ports, each one of which operable to electronically receive given input hardware port-specific cryptographic data thereon to initiate execution of an internal cryptographic process as a function thereof; two or more segregated hardware port-specific storage spaces each operatively linked to a corresponding one of said hardware ports via a corresponding hardware link, and storing respective secured hardware port-specific cryptographic data thereon exclusively retrievable as a function of said given input hardware port-specific cryptographic data corresponding thereto; and a cryptographic engine operable to execute said cryptographic process based on said secured port-specific cryptographic data retrieved from said segregated hardware port-specific storage spaces as a function of said given input port-specific cryptographic data.
