Various groups have expressed concerns over the privacy implications of the data providers would be required to retain under the act, including the
Electronic Frontier Foundation, the
American Civil Liberties Union, and the
American Library Association. the nature of the data collected, Even though only assigned IP addresses and certain subscriber data would be retained, some commenters, including the EFF and some editorialists, have suggested that the data could be used to deduce any given user's personal habits, including a detailed map of where they customarily are at any given point in a day. The CDT also issued a comprehensive memorandum regarding the Data Retention Mandate in H.R. 1981, in which it detailed how data retention provisions in H.R. 1981 would raise issues concerning privacy and free speech, among the few other issues that the bill raises. Representative
Zoe Lofgren, (D-Calif.), a vocal opponent of the bill, presented an amendment to rename the bill the "Keep Every American's Digital Data for Submission to the Federal Government Without a Warrant Act." Rep.
John Conyers (D-Mich.) also opposed it, saying "This is not protecting children from
Internet pornography. It's creating a database for everybody in this country for a lot of other purposes." Lamar Smith, however, has defended the data retention requirements present in the bill in stating that, "Some Internet service providers currently retain these [IP] addresses for business purposes. But the period of retention varies widely among providers, from a few days to a few months. The lack of uniform data retention impedes the investigation of Internet crimes." Smith also stated that the number of child pornography cases has grown by 150% per year over the past ten years. Marc Rotenberg, president of the
Electronic Privacy Information Center has gone on record for saying that "the bill's expansion of data retention is counter to the growing practice to limit data retention as a mechanism to counter security threats." In addition, Rotenberg also mentions that in fact, there is a strong movement towards
data minimization in the information security arena, and that data retention is in direct conflict with that notion. Rotenberg concluded that data minimization and not data retention is the best way to protect
consumer privacy. ==Cost==
