Attacks On Reputation Systems
Reputation systems are in general vulnerable to attacks, and many types of attacks are possible (Jøsang & Golbeck 2009). A typical example is the so-called Sybil attack where an attacker subverts the reputation system by creating a large number of pseudonymous entities, and using them to gain a disproportionately large influence (Lazzari 2010). A reputation system's vulnerability to a Sybil attack depends on how cheaply Sybils can be generated, the degree to which the reputation system accepts input from entities that do not have a chain of trust linking them to a trusted entity, and whether the reputation system treats all entities identically. It is named after the subject of the book Sybil, a case study of a woman with multiple personality disorder.

Famous quotes containing the words attacks on, attacks, reputation and/or systems:
“We are seeing an increasing level of attacks on the “selfishness” of women. There are allegations that all kinds of social ills, from runaway children to the neglected elderly, are due to the fact that women have left their “rightful” place in the home. Such arguments are simplistic and wrongheaded but women are especially vulnerable to the accusation that if society has problems, it’s because women aren’t nurturing enough.”
—Grace Baruch (20th century)

“The esteem of good men is the reward of our worth, but the reputation of the world in general is the gift of our fate.”
—François, Duc De La Rochefoucauld (1613–1680)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
