[en] Paper: LLMs can be used to perform at-scale #deanonymization

"With full Internet access, our #agent can re-identify Hacker News users and Anthropic Interviewer participants at high precision, given #pseudonymous online profiles and conversations alone, matching what would take hours for a dedicated human investigator."

"Our results show that the practical #obscurity protecting pseudonymous users online no longer holds and that #threat models for online #privacy need to be reconsidered."

"We demonstrate that LLMs fundamentally change the picture, enabling fully automated deanonymization attacks that operate on #unstructured text at scale."

Note: also check paragraphs "Potential harms" and "Potential benefits".

Large-scale online deanonymization with LLMs

A quotation from Horace

Dear sire, and offspring worthy of your fire!
We bards are dupes to what ourselves admire.
Would I be brief — I grow confused and coarse;
Who aims at smoothness, fails in fire and force;
In him who soars aloft, bombast is found;
Who fears to face the tempest, crawls aground.
Who courts variety and fain would ring
A thousand changes on the self-same string,
Will paint, as ’twere in fancy’s wildest mood
Boars in the wave and dolphins in the wood.
Thus even error, shun’d without address,
Breeds error, diff’rent in its kind, not less.
 
[Maxima pars vatum, pater et iuvenes patre digni,
decipimur specie recti: brevis esse laboro,
obscurus fio; sectantem levia nervi
deficiunt animique; professus grandia turget;
serpit humi tutus nimium timidusque procellae:
qui variare cupit rem prodigialiter unam,
delphinum silvis adpingit, fluctibus aprum:
in vitium ducit culpae fuga, si caret arte.]

Horace (65–8 BC) Roman poet, satirist, soldier, politician [Quintus Horatius Flaccus]
Epistles [Epistularum, Letters], Book 2, ep. 3 “Art of Poetry [Ars Poetica; To the Pisos],” l. 24ff (2.3.24-31) (19 BC) [tr. Howes (1845)]

Obscurity haben auch ein neues Album draußen. Supertoll. Geht thematisch diesmal um den Konflikt zwischen christlichem Imperialismus und germanischen Stämmen, die ihre Kultur dagegen verteidigen. Wobei die Erzählperspektive primär aus heidnischer Sicht ist.

A quotation from Orwell

When I think of antiquity, the detail that frightens me is that those hundreds of millions of slaves on whose backs civilization rested generation after generation have left behind them no record whatever. We do not even know their names. In the whole of Greek and Roman history, how many slaves’ names are known to you? I can think of two, or possibly three. One is Spartacus and the other is Epictetus. Also, in the Roman room at the British Museum there is a glass jar with the maker’s name inscribed on the bottom, “Felix fecit.” I have a vivid mental picture of poor Felix (a Gaul with red hair and a metal collar round his neck), but in fact he may not have been a slave; so there are only two slaves whose names I definitely know, and probably few people can remember more. The rest have gone down into utter silence.

George Orwell (1903-1950) English journalist, essayist, writer [pseud. of Eric Arthur Blair]
Essay (1942-08), “Looking Back on the Spanish War, ch. 4, Such, Such Were the Joys, essay 8 (1953)
