Dragging Telephone Numbers Into the Internet Age
azoblue writes with this teaser from Ars Technica, presenting a tempting suggestion for online consolidation: "E-mail, IM, Facebook, phones—what if all of these ways to reach you over a network could be condensed into a single, unique number? The ENUM proposal aims to do just that, by giving everyone a single phone number that maps to all of their identifiers. Here's how it works, and why it isn't already widely used."
Great, then spammers only need one number to send you all sorts of spam in all kinds of different ways. And even better, they can try random numbers!
Why would I want a "number" for that? That's why DNS was invented, so we could move forward from using numbers to identify things and use proper identifiers instead. This is a step backwards in many ways.
But I'm not quite sure why I would want to tie all my shiny new contact mechanisms to a 19th century relic controlled by the telcoms, entities which are sclerotic at best and downright evil at worst.
ENUM seems like the sort of thing that would happen if you got a bunch of fairly sharp techies together and told them that it was an axiomatic, foundational, truth that telephone numbers must remain relevant and central to communication. Within those constraints, they seem to have come up with a good solution. Those constraints, though, seem irrelevant. The internet, and its design philosophies, is simply better.
would you use the phone number as a universally unique id?
One user might have several phone numbers, while the one phone number might have several users.
Additionally, the phone number is not portable across national borders. You can not bring your Norwegian phone number and use it with an american registrar.
Additionally users might be forced at regular basis to change their phone numbers. Me for one, had to change my phone number when I changed employer.
Database designers have known this for ages. Always assign a new unique id to any row in a table. Ids that seem unique and stable might change. Even social security numbers might change.
Oh.. Who would want all their contact info to be collected in one global system available for all?
I do not want a single number, because I do not have a single identity.
I do not want my work to call me on my personal phone, so they don't have that number. But my job naturally requires some amount of phone work, so they all have *that* number. Makes sense, right?
"Good news, everyone!"
I prefer a mobile with just 10 data entry keys.
The user-friendliness of having to select something from a 150 entry drop-down or having to press every key (a different) multiple times is vastly overrated.
A single number to identify people would be just as powerful as a SSN or driver's license number. It would make fraud so much easier. Eventually people would compile databases tying these IDs to SSNs and would distribute those online. Then we would start seeing advisories to keep your single contact number a secret!
On the positive side, perhaps this would help to convince financial institutions that simply knowing someone's SSN and mother's maiden name doesn't prove anything about identity.
i've thought about this before - i think what one needs is a single PRIVATE number - that never gets given out to anyone - and you have a bunch of private ALIAS/Reference numbers which you yourself point to your private number - then you only give out the aliases - and if one of the aliases gets overloaded, you pull the plug on the alias, create a new alias, and then direct that new alias towards your private number.
