"As a general principle, bookstores should not be selling dossiers on their customers' reading habits," the letter says.
Amazon reached an agreement with state regulators last month to curtail the sharing of consumer information with third parties after coming under pressure from consumer groups, privacy advocates and government authorities. But despite the deal, some privacy groups are claiming that Amazon still has not done enough to protect consumers' personal information, and are requesting that authorities take further measures to restrict the e-tailer's use of consumer data.
In their letter sent Tuesday, the Electronic Privacy Information Center (EPIC) and Junkbusters Corp. asked regulators to require Amazon to obtain customers' consent before transferring personal information in the case that it sells one of its business units, and allow consumers to access and delete certain purchase records or dissociate themselves from their transactions.
Amazon representatives were not immediately available to comment on the letter Tuesday.
