1. An electronic device comprising:
a camera;
a microphone;
one or more processors; and
one or more computer readable media storing processor executable instructions which, when executed using the one or more processors, cause the electronic device to perform operations comprising
generating first image data using the camera,
generating, based on encoding the first image data, a plurality of blocks,
determining a first set of blocks of the plurality of blocks,
determining a first hash value based on
a first block of the first set of blocks, and
authentication data,
determining a second hash value based on
a second block of the first set of blocks, and
a hash value determined based on a block of the first set of blocks other than the second block,
generating encrypted data based on
the second hash value, and
a key stored at the electronic device,
determining signature data comprising the authentication data and the encrypted data,
transmitting to a remote system
data representing the first set of blocks, and
the signature data.
