End Users. Whether the end user is a Lab, a patient, a grocer, a consumer or other entity, each user will be able to view through the Media Sourcery XChain solution the path their asset(s) have traveled with all the metadata that is associated with that asset. This metadata can include storage and transport temperature, GPS coordinates, time stamps, documentation, the identity and calculated reputation of the person or system that loaded the metadata, and many other attributes. If there is an end of life or expiration on the asset, end users will be notified before and on this date.
