1. A method for tamper-evident storage of a media stream using a data structure comprising a payload field and an associated metadata field, the method comprising:
obtaining a portion of the media stream from a media source;
determining a set of parameters to be stored in the metadata field of the data structure, the set of parameters associated with the portion of the media stream to be stored in the payload field of the data structure;
obtaining a progenitor parameter to associate with the set of parameters by hashing a metadata field, defining a previous set of parameters associated with a previous portion of the media stream, from a previous data structure storing the previous portion of the media stream, the previous data structure having previously been rendered tamper-evident;
incorporating the progenitor parameter into the set of parameters and storing the set of parameters in the metadata field of the data structure; and
storing the portion of the media stream in the payload field of the data structure.
