Abstract
In general, one aspect disclosed features a media-capture device, comprising: one or more sensors; a hardware processor; and a non-transitory machine-readable storage medium encoded with instructions executable by the hardware processor to perform a method comprising: initiating acquisition of one or more sensor data samples representing analog phenomena captured by the one or more sensors; receiving the one or more sensor data samples; encoding the one or more sensor data samples; generating a to-be-signed data structure comprising at least one of: the one or more encoded sensor data samples, or one or more cryptographic hashes of the one or more encoded sensor data samples; generating a cryptographic hash of the to-be-signed data structure; determining whether a time-stamping server is reachable over a network connection by the media capture device; and configuring a second data structure based on the determination of whether the time-stamping server is reachable.
