Abstract
The present disclosure relates to systems and methods for tamper-evident storage of a media stream, and for serving tamper-evident media. The tamper-evident media is stored using a data structure comprising a payload field and an associated metadata field. A portion of a media stream is obtained from a media source. A set of parameters, to be stored in the metadata field of the data structure, is determined. A progenitor parameter to associate with the set of parameters is obtained, the progenitor parameter based on a hash of at least part of a previous data structure storing a previous portion of the media stream. The progenitor parameter is incorporated into the set of parameters, and the set of parameters is stored in the metadata field of the data structure. The portion of the media stream is stored in the payload field of the data structure.
