Just base64_decode() the data:

$blob = base64_decode($json_64_encoded_string);

Then write it to the DB. If you need help getting the encoded string out of the POST array have a look at the PHP json_decode function: http://php.net/manual/en/function.json-decode.php

$json_obj = json_decode($_POST[post_key]); //replace 'post_key' with whatever you use
$blob = base64_decode($json_obj->blob); //replace 'blob' with whatever you use
