summary | Translucent Databases cure "Database Nation" and the "Transparent Society"? |
Translucent Databases has all the hallmarks of Wayner's books: clear, easy to read exposition of the main issues, why they're important, and, in his technical books, excellently documented code written for the most popular platforms for the technology in question.
This book in particular should be an instant classic because like all great books, it takes what should be a very simple idea, encrypted databases, and expands it to some amazing conclusions.
For a long time now, I've been interested in what I call the geodesic economy, where all information, including information controlling financial assets, is fractally "surfacted", like so much grease in soapy dishwater, as far out into the edges of a ubiquitous internetwork as Moore's Law will allow, using financial cryptography protocols to secure transactions and markets on a nominally insecure, but ubiquitous, public internetwork.
People who are familiar with my thinking about such things over the past 8 years will see quite quickly why I think Peter's new book is so important. Transparent databases represent a way not only to link the batch-settled, book-entry debit-for-credit world of modern financial operations with a more simply founded, but much more sophisticated world which uses cryptographic tokens representing control of various financial and real assets. They also show us how to actually account for those tokens in such a fashion that every financial actor in that market, man or machine, can trust that their bearer certificates are authentic ones, and done in such a fashion that a given token retains its cryptographic integrity, including the functionally anonymous characteristics that made it so cheap to use in the first place.
The singular feature of Wayner's translucent databases is that, like internet bearer transactions themselves, the cryptography securing data in them can happen in the client, and not a centrally vulnerable server. More to the point, by using data stored in this fashion, the data can be dispersed as far out in the network as... well, Moore's Law allows, in extremely fast and lightweight files, and, instead of creating summaries of data for reports, the data can be polled for as close to its source as possible, instantaneously, in realtime, instead of being rolled up into increasingly larger batch-processed summaries taking weeks, sometimes months, to produce and audit.
There are obvious implications for my own particular hobby-horses, like anonymous but accurate double spend databases for bearer transactions, where only a simple blinded m-of-n cryptographic hash of a given promise to pay is necessary to prevent the duplication of that promise to more than one person at a time. However, for the rest of us :-), Wayner also points to a whole host of much less esoteric applications in the lots of the usual places where absolute privacy and extremely authentic information, is at a premium. Examples for military, medical, and anti-rape databases, for accounting systems and securities transactions, and even for internet poker -- the paradigm of completely untrusted parties cooperating for what each player hopes will be his own, preferrably cash, benefit -- are all presented in clear writing and running code.
There has been a lot of lip-service in the privacy community about "owning" your own data. Unfortunately, by involving the state at all, these "advocates" almost always favor inadvertantly draconian political solutions to the problem presented by the ubiquity of database technology and its otherwise beneficial presense in our lives. They ususally present this nonsense as a "sacrifice" for the "greater good" that would make Hayek's Road to Serfdom look like Lilac Sunday at the local arboretum.
In Translucent Databases, Wayner shows, in precise detail, with code, how to solve that problem, without trusting lawyers, much less guys with guns.
Though quite a short read, the scope of the book itself is quite considerable. Wayner starts from simple hashes of data to merely obscure it, through various kinds of encryption, quantization of data, and even accounting with encrypted data using what amounts to virtual cumulative crossfoots like the kind you would see on all good accounting reports. In so doing, Wayner explains, quite simply, something that people like Eric Hughes made great, complicated hay out of years ago with gangling theories of encrypted "open" books.
Ultimately, Wayner really does end up where a lot of us think databases will be someday, particularly in finance: repositories of data accessible only by digital bearer tokens using various blind signature protocols, neatly, and quite literally, "dis-integrating" the ability of databases to be used against us as a tool of totalitarianism, exemplified most recently by Simpson Garfinkel in his book Database Nation , and, oddly enough, not because someone or other wants to strike a blow against the empire, but simply because it's safer -- and cheaper -- to do that way.
Every database programmer should have a copy of this simple and elegant book on his reference bookshelf. Particularly if he cares about the integrity of his data, the liability to the database's owner should information be misappropriated, and, not least, about freedom itself in a world of ubiquitous, and, frankly, necessary, stored detail: details about practically every person on earth, their property and finances, and, ultimately, everything they do.
Translucent Databases presents a simple, frankly beautiful, solution to David Brin's world of ubiquitous surveillance, one not requiring, as Brin seems to want, "trust" of state force-monopolists, much less their lawyers and apparatchiks.
In fact, it's such an elegant solution that, as Schopenhauer liked to say about the public acceptance of important new ideas, soon enough, people will say it was obvious all along.
Robert Hettinga is founder of IBUC, the Internet Bearer Underwriting Corporation, which will, hopefully, someday, :-), use translucent databases full of internet bearer certificates to reduce transaction costs by three orders of magnitude.
