Unikatna uporabniška imena na internetu omogočajo profiliranje

Unikatna uporabniška imena na internetu omogočajo profiliranje

Technology Review - Pri nadzoru nad podatki, ki jih puščamo naokoli po spletu, mnogokrat pozabimo na kratek enoličen identifikator, ki ga potrebujemo za prijavo na različne strani - na uporabniško ime. Toda ne smemo ga pozabiti, saj so raziskovalci s francoskega Nacionalnega inštituta za računalniške znanosti (INRIA) v članku How Unique and Traceable are Usernames? pokazali, da lahko preveč unikatna uporabniška imena, ki jih uporabimo na več straneh, omogočajo profiliranje uporabnikov.

Kot vzorec so vzeli deset milijonov uporabniških imen, ki so jih pobrali z Googlovih profilov, računov za eBay in drugih strani. Ugotovili so, da lahko polovico teh uporabniških imen povežejo z računi na več straneh in učinkovito izdelajo profil uporabnika. Bolj kot je uporabniško ime unikatno, nižjo entropijo ima in laže ga je križno povezati med različnimi stranmi, kjer je bilo uporabljeno. To utegnejo izkoristiti oglaševalci za ponujanje bolj ciljanih oglasov ali prevarantje pri postavljanju prepričljivih ribarskih strani. Raziskovalci so izdelali tudi stran, kjer lahko preverimo unikatnost svojega uporabniškega imena.

ampak unikatnost je včasih tisto kar si želimo, nekaterim je všeč, da dobimo samo oglase ki nas zanimajo, ne pa da gledamo oglase za povečanje prsi. spet drugič nam paše, da nas ljudje poznajo na vseh spletnih straneh, ne pa da si moramo identiteto vedno znova ustvarjati.

Sicer je to res, ampak če želiš to doseči, moraš imeti hkrati preprosto in unikatno ime, če je 10 random črk, bo to sicer unikatno, ampak zapomnu se te nebo nihče:).

Mislim da to ni neka pogruntavščina. Če bi hotli med na vsaki strani drugo uporabniško ime da mamo drugo identiteto potem bi si jo dali. Večji problem je tracking in profiliranje s pomočjo unikatnosti brskalnika.
Your browser fingerprint appears to be unique among the 1,430,801 tested so far.

Currently, we estimate that your browser has a fingerprint that conveys at least 20.45 bits of identifying information.

Preporosto povedano -- unidentifiable pomeni, da je vaše uporabniško ime dovolj pogosto rabljeno, da ne morejo zagotovo trdit, da je Bigwhale@google == Bigwhale@ebay.


Based on language models and Markov Chain techniques, our model validates an intuitive observation: usernames with low "entropy" (or to be precise Information Surprisal) will have higher probabilities of being picked by multiple persons, whereas higher entropy usernames will be very unlikely picked by multiple users and refer in the vast majority of the cases to unique users.


Zanimivo je pa tudi tole

Third, we extend this model to cases when usernames are di erent across many online services. In essence, given two usernames our technique returns the probability that these usernames refer to the same user, and allows then to e ectively trace users identities across multiple web services using their usernames only. While we acknowledge that our technique cannot trace users that choose unrelated usernames on purpose, experimental data shows that users tend to choose closely related usernames on di erent services.
