A potential change in the US government's policy that would permit the broad use of web cookies on government sites could "allow the mass collection of personal information," according to the American Civil Liberties Union (ACLU).
A spokesman with the White House Office of Science and Technology (OSTP) wasn't immediately available for comment on the ACLU concerns.
The ACLU isn't necessarily opposed to the US government using cookies in some circumstances, but there need to be strong privacy safeguards in place, said Michael Macleod-Ball, acting director of the ACLU Washington, DC, Legislative Office.
"We'll have to put some very shielded boxes around the information that's being collected, retained and used," he said.
The Kundra and Fitzpatrick blog post also said the government shouldn't discriminate against web surfers who opt out of government cookies. But Macleod-Ball suggested that the government should get opt-in permission before it assigns tracking cookies to visitors of government web sites.
"I don't think the opt-out thing works for us in a government context," he said.
Many private web sites allow users to opt out of tracking technologies, but few get opt-in permission before issuing tracking cookies.
While Macleod-Ball said he wasn't opposed to the government's use of some cookies, several people posting comments on OSTP's blog said they were opposed to the government collecting personal data.
"The current 'cookie' policy should be kept in place," one person wrote. "The potential for abuse in gathering a person's personal computer data is too great and yet another example of the Federal Government trying to intrude in the private lives of its citizens."
Another poster commented: "Keep your nose out of my business, your snitches off my back and your cookies out of my computer."
"If permitted, persistent cookies will enable government websites to move to the next level in offering our patrons increased customisation instead of one-size-fits-all websites," wrote Valerie Allen, web manager for several government sites hosted by the US Department of Energy's Office of Scientific and Technical Information. "These capabilities are routinely available on nongovernmental sites. As technologies advance, federal government websites may fall behind due to limited options open to developers, and with it an overall decrease in user satisfaction."
