Abstract: Disclosed herein are embodiments for a record-level encryption scheme. A data visibility control platform may facilitate record-level encryption between a data owner device and a requester device, requesting access to the encrypted record. The record may contain sensitive and/or confidential information of the data owner. The data owner may directly control the visibility of the record via the data visibility control platform. The data visibility control platform may use a combination of private and public cryptographic keys associated with the data owner and requester to provide record-level encryption. An embodiment may include record keys used to encrypt records being stored by a records database managed by a data intermediary. The record key may be encrypted using the public key of the data owner and stored on a blockchain. Access to the record key stored on the blockchain is controlled by the data owner.

Abstract: Disclosed herein are embodiments for implementing periodic management of cryptographic keys. An embodiment includes a processor configured to perform operations comprising receive a first input associating a first set of subscribers with a first data stream published by the first publisher device, and a first cryptographic key. Processor may transmit, to the first publisher device, a first confirmation, indicating that the first cryptographic key is ready for use, for example. In some embodiments, processor may release the first cryptographic key to a first set of subscribers, receive a second input from a publishing user, associating a different, second set of subscribers with the first data stream, and receive a second cryptographic key after a certain time period. Processor may further transmit, to the first device, a second confirmation, indicating that the second cryptographic key is ready for use, and release the second cryptographic key to the second set of subscribers.

Abstract: Embodiments disclosed herein for processing signals from sensor groups include processor(s) configured to perform operations comprising sampling, at a configurable signal sampling interval, a plurality of signal sample values via the one or more output signal traces from the plurality of remotely located sensors; storing, in a transmission array, an available portion of parameters extracted from a first timeslot array and from a second timeslot array, wherein the available portion of parameters is extracted using an algorithm configured to assign specific parameters to the transmission array, independent of the sampling; and transmitting, to an external communications network, an available portion of the parameters stored in the transmission array, at a transmission interval, wherein the transmission interval is independent of timeslot durations of the first timeslot array and the second timeslot array, and wherein the transmitting operation is performed independently of the storing operation of the available

Abstract: Briefly, embodiments of methods and/or systems of sampling output signal traces by one or more function processors for storage into timeslot arrays are disclosed. In one embodiment, responsive to availability of a connection to an external communications network, computed results of function processing may be conveyed along the external communication network. Responsive to loss of communications to the external communications network, computed parameters may be stored in one or more timeslot arrays, signal sampling intervals, timeslot durations, and transmission frequency to be independent from one another.
