Abstract: Content of different formats may be sourced from various data sources such as content servers and ingested into a data integration server by an ingestion broker embodied on a non-transitory computer readable medium. The ingestion broker may normalize the content of different formats into a uniform representation that can be indexed and delivered across multiple digital channels for a variety of applications. The normalized content may be analyzed and semantic metadata may be determined from the normalized content. The normalized content can be semantically enriched by associating the semantic metadata and the like with the content. The semantic metadata can be stored in a semantic index that can be used for searching via the data integration server. During search, the semantic metadata can be instantiated as facets for user navigation and refinement of search criteria and additional semantic relationships can be assigned to the words in the normalized content.

Abstract: An obfuscation circuit relies on a tamper-resistant nonvolatile memory which encodes a trusted Boolean function. The Boolean function is used to enable several operations relating to circuit obfuscation, including obfuscation of logic circuitry, obfuscation of operand data, and release of IP blocks. The tamper-resistant nonvolatile memory is part of a trusted integrated circuit structure, i.e., one fabricated by a trusted foundry, separate from another integrated circuit structure which contains the various operational logic circuits of the design and is fabricated by an untrusted foundry. The Boolean function is encoded based on a look-up table implemented as a cascaded multiplexer circuit. Multiple obfuscation functions can be so encoded. The obfuscation functions may be reprogrammed using a protocol that relies on symmetric keys, one of which is stored in the tamper-resistant nonvolatile memory.
