We would write a scaling server with Go on one of these public datacenter services. A manufacturer or distributor could register a UUID with us that is then verified through us by the pharmacy and consumer later. The pharmacy/consumer has the aztec barcode with the UUID, manufacturer cryptographic number, and distributor cryptographic number, so maybe we’re talking about two barcodes and a distribution standard.
Capturing already-scanned UUIDs may mitigate some copying, or at least indicate to the consumer or pharmacy that there's a copier problem. Would the picture be processed by the server or by the client? How are existing Go libs for these aztec barcodes? We'd need an authentication system for people or organizations registering UUIDs. Could we have data tied to the UUID on the target distributor, target pharmacy, or target consumer? “when we are looking at the source, we are looking at the stock cards, and also cross-checking with the delivery sheet to confirm this is what is being supplied” In Kenya one distributor handles 40% of the country’s medicine supply. They have a QA process. But: “Many small storefronts buy from unauthorized distributors” - we’re not fixing this part except maybe through consumer knowledge (“we’re expecting the bar code”). PBS pointed out barcoding as a solution put into place already. Thomas Woods of the World Bank talks about “rapid authentication devices”. As a group of app implementers I think we’d be best served by partnering with an organization with connections to the industry instead of directly with manufacturers or distributors. Who can we talk to? I think this is on-topic for golang-nuts as we’re discussing a use case of Go and programming: building global information services. Maybe somebody can use our designs for their Go service later.
