Abstract: The present disclosure provides systems and methods for timestamping events on edge devices. A trusted source measures the latency to the edge device and the edge device's clock offset, and stores the information at the trusted source for later use. The trusted source sends the latency and the device's clock offset to the edge device for later use. The trusted source or the edge device adjusts a timestamp generated at the edge device using an estimated clock offset. The estimated clock offset is determined by extrapolation or interpolation from measured clock offsets.

Abstract: The present disclosure describes systems and methods for aggregation and management of cloud storage among a plurality of providers via file fragmenting to provide increased reliability and security. In one implementation, fragments or blocks may be distributed among a plurality of cloud storage providers, such that no provider retains a complete copy of a file. Accordingly, even if an individual service is compromised, a malicious actor cannot access the data. In another implementation, fragments may be duplicated and distributed to multiple providers, such that loss of communications to any one provider does not result in inability to access the data. This implementation may be combined with error correction techniques to allow recovery, even with loss of multiple providers. File synchronization may also be faster in these implementations by dividing reading and writing operations among multiple providers.
