We spend a lot of time talking about digital identity for people and speculating about whether Apple ID or federated Bank ID or centralised Government ID is the best implementation. But in the new online world, there are a great many things other than people that will need to have digital identities in order to participate in a functioning post-industrial economy. Things, for example. Bots will need identities. In fact I’m writing a book about this at the moment. It’s going to be called “Will Robots Need Passports?” and it will be out next year sometime.
(And the answer, as I am sure you already know, is “yes”. Spoiler alert: robots will need passports because they will need to have reputations.)
What we don’t spend anything like enough time talking about though is the digital identity of animals. I read with great interest a report in the Times of India about a new smartphone app that farmers can use to check information about cattle. This was developed in response to an appeal from Prime Minister Modi for a means to reduce cattle theft. As you probably know, India already has a national identity number for people and it has worked pretty well, providing a low-cost mechanism to establish the unique identities of citizens and thereby contribute to the goal financial of financial inclusion which (as everyone knows) is an identity problem. Therefore, it would seem logical to give animals a number too.
But how do you tell Napoleon from Snowball? Well, specific information “unique to each animal” like the footprint, height, weight, colour and tail hair is recorded in the software and a unique ID is generated. As one of the designers of the software notes, this ID “is very useful when insuring cattle”, which is a good point. I am slightly surprised that, all other things being equal, they didn’t put the IDs on a quantum-resistant blockchain in the cloud, but that’s probably version 3. Nevertheless, biometric identification of animals and the association of a digital identity clearly has economic value. I don’t know how unique animal footprints are, so I cannot comment on adjusting the false accept and false reject for optimal barnyard efficiency, but I do know that (as the Wall Street Journal recently reported) face recognition for animals is actually pretty difficult. As they put it, “It’s not like you can tell a donkey to stand still“. Quite. Nevertheless it can be done.
I know this because I was privileged to have Dr. Jion Guong Shen from JD Digits, a subsidiary of JD (China’s largest e-commerce business) on my panel about AI ethics and governance at the Innovate Finance Global Summit (IFGS) last year. This was a great panel, by the way, largely because the well-informed panellists took the discussion in such interesting and unexpected directions. Anyway, this panel is relevant because JD Digits, amongst other things, runs face recognition services for farmyard animals including cows and pigs. It turns out that pig face recognition, in particular, is a big business, There are 700m pigs in China, and the productivity gains that farmers can obtain from ensuring that each pig is fed optimally, that sick pigs are kept away from the herd (and so on) are very significant.

Apparently the face recognition system also goes some way to reigning in wannabe Napoleons, as Dr. Shen explained that there are some “bully pigs” that try to obtain a disproportionate share of barnyard resources. The system can spot them chowing down when they shouldn’t be and flag for intervention. This is a pretty straightforward use case for biometric identification that might useful introduced into British fast food outlets in my opinion.
All of which is by way of noting that digital identities are not only for people and that the future economy desperately needs digital identity infrastructure for everything. Aadhar for animals is an interesting first step, but it really is only a first step.
