Patent number: 11372854Abstract: Provenance analysis systems and methods. Datums representing relationships between entities can be stored in a knowledge store. Datums can be received from agents as agents perform activities. Activity records are be stored in a provenance graph, the activity record and associate received datums with any input datums used in the activity. Provenance subgraphs can 5 be retrieved by traversing the provenance graph for selected datums and presented through a user interface. Provenance subgraphs can be augmented with trust modifiers determined based on attributions, confidences, and refutations provided by a user. Trust modifiers can be propagated downstream to enable the addressing of junctions in variable confidence.Type: GrantFiled: September 11, 2020Date of Patent: June 28, 2022Assignee: Smart Information Flow Technologies, LLCInventors: Scott Ehrlich Friedman, Jeffrey Mathew Rye, David Thomas LaVergne

Patent number: 11256561Abstract: A computer detects a crash of a computer program, the crash being caused by a faulting instruction. The computer determines, within concrete stack frame(s) of the computer program, memory position(s) and extent(s) of input. The computer maps, using the memory position(s) and the extent(s), inferred stack frame(s) onto concrete stack frame(s), the inferred stack frame(s) indicating positions of variables used in the computer program. The computer identifies, based on mapping the inferred stack frame(s) onto the concrete stack frame(s), at least one variable from among the variables that is within a stack overflow memory and within a dataflow path to the faulting instruction, wherein the dataflow path to the faulting instruction indicates the variables used in the computer program that are accessed by or contribute to the faulting instruction. The computer determines whether the stack overflow contributed to the crash of the computer program.Type: GrantFiled: March 4, 2021Date of Patent: February 22, 2022Assignee: Smart Information Flow Technologies, LLCInventors: Peter Kelly Keller, David John Musliner
