Secure continuous compliance enforcement on a data exchange system
An exchange template framework for a data platform. A data provider of the data platform instructs the data platform to generate an exchange template based on compliance rules. In response to determining by the data platform to initiate a compliance report, the data platform maps evidence items for the compliance report from one or more source tables using a data field mapper of the exchange template. The data platform generates compliance program specific views based on the evidence items mapped from the source tables and generates an anonymized view based on the compliance program specific views using an anonymization layer of the exchange template. The data platform provides the anonymized view to an assessor using one or more validation scripts of the exchange template. |

RTOS/OS architecture for context switching that solves the diminishing bandwidth problem and the RTOS response time problem using unsorted ready lists
The present invention is a novel RTOS/OS architecture that changes the fundamental way that data is organized and context switching is performed. This novel approach consists of a context switching method in which interrupts are never disabled. This RTOS/OS architecture requires specialized hardware. Concretely, an advanced interrupt controller that supports nesting and tail chaining of prioritized interrupts is needed (e.g. the Nested Vectored Interrupt Controller (NVIC) found on many ARM processors) is required. The novel RTOS/OS architecture does not keep the list of tasks ready to run in sorted order, allowing for O(1) insertion time and utilizes a barrier variable to allow for safe O(n) insertion of tasks into the priority sorted list of blocked tasks without disabling interrupts. The advanced interrupt controller allows for any new interrupts to preempt the software exception handler thereby ensuring no data loss. This novel RTOS/OS architecture eliminates the diabolical deficiency existent in current architectures which creates a superficial dependency between the number of tasks in the system and the maximum bandwidth that can be sustained at some peripheral. That is, this architecture ensures that the maximum bandwidth never decreases as more tasks are added to the system. |
