2 results about "Obfuscation" patented technology

Described is a system for protecting sensitive information that is hardcoded in polynomial-size ordered binary decision diagram (POBDD) form. A software executable represented as a POBDD having sensitive information embedded therein is obfuscated into an obfuscated POBDD. An input query on the obfuscated POBDD is evaluated, and the sensitive information is revealed only if the input query is a correct input. Thus, an adversary is prevented from extracting the sensitive information embedded in the POBDD.

A method and apparatus are disclosed for identifying an object with specific characteristics and automatically obfuscating part or all of a digital image corresponding to that object. The obfuscation comprises pixelation, color alteration, and/or contrast alteration. The obfuscation optionally can be performed only when the digital image is being viewed by certain client devices.
