> more sensitive personal information (like social security numbers or other government ID numbers) I tend to think that there should be a publicly accessible, unique, and more or less immutable ID number for every citizen or resident. This ID would have pointers to our name, birth date and a few other identifiers that shouldn't really be considered secret. My concern is that the absence of such a unique ID leads to a mess of overlapping systems in which only large organizations with the resources to track everyone will be able to uniquely identify people. So we'll have a degree of anonymity from random other individuals, not not from banks, tech corporations or the government. Computing power is becoming too cheap and ubiquitous to effectively hide information that isn't explicitly confidential. That is, as a society we need to adjust to a paradigm in which it is more expensive to keep information confidential than to allow it to be public. Especially keeping information private from those with deep pockets.
