Scalable and extensible secure rendering of digital content

A processor implemented method, comprising:

• a root one of a plurality of hierarchically organized plain text digital content rendering modules collectively equipped to render digital contents of a plurality of types requesting a tamper resistant digital content recovery module to recover a first protected digital content of a first type;
• the tamper resistant digital content recovery module verifying that said root one of the plurality of hierarchically organized plain text digital content rendering modules has not been comprised;
• the tamper resistant digital content recovery module recovering the first protected digital content in an obfuscated manner, and transferring the recovered first digital content to said root one of the plurality of hierarchically organized plain text digital content rendering modules;
• and
• said root one in conjunction with first at least one other one of said plurality of hierarchically organized digital content rendering modules rendering said first digital content, with each of said root and non-leaf ones, if any, of said first other ones of said plurality of hierarchically organized digital content rendering modules verifying an immediate downstream module is uncompromised before transferring the first digital content to the immediate downstream module to further the rendering of the first digital content.

An apparatus comprising:

• a plurality of digital content rendering modules communicately coupled with each other in a hierarchical manner forming a hierarchy of modules, with selective combinations of which to be selectively employed to protectively render digital contents of corresponding types, including one of said digital content rendering modules occupying a root position of the hierarchy to exclusively receive the digital contents to be rendered, of all types, from at least a separate recovery module responsible for recovering the digital contents from their ciphered states, and each of the non-leaf ones of the digital content rendering modules being responsible for verifying to its own satisfaction that its immediate downstream module or modules, if any, have not been compromised;
• one or more storage units to store said plurality of digital content rendering modules;
• and
• a processor coupled with the one or more storage units to execute the digital content rendering modules.

A processor implemented method comprising

• each of a plurality of hierarchically organized digital content rendering modules verifying to its satisfaction that each of its immediate downstream module, if any, is uncompromized, during an initialization period;
• a root one of the plurality of hierarchically organized digital content rendering modules exclusively receiving a first digital content of a first type;
• and
• said root one in conjunction with first at least one other one of said plurality of hierarchically organized digital content rendering modules rendering said first digital content, with each of said root and non-leaf ones, if any, of said first other ones of said plurality of hierarchically organized digital content rendering modules further verifying an immediate downstream module is uncompromised before transferring the first digital content to the immediate downstream module to further the rendering of the first digital content.

An article of manufacture comprising:

• a recordable medium;
• a first plurality of programming instructions recorded on said recordable medium, with said first programming instructions designed to program a computing device, to implement on the computing device, a tamper resistant digital content recovery module to recover protected digital contents of various types in an obfuscated manner;
• and
• a second plurality of programming instructions recorded on said recordable medium, with said second programming instructions designed to program a computing device, to implement on the computing device, a plurality of plain text digital content rendering modules communicately coupled with each other in a hierarchical manner forming a hierarchy of modules, with selective combinations of which to be selectively employed to render the recovered digital contents of corresponding types, including one of the plain text digital content rendering modules occupying a root position of the hierarchy to exclusively receive the recovered digital contents to be rendered, of all types, from a tamper resistant digital content recovery module.
