Google's accidental release of private information of users this month has led to an online privacy group's calling upon the federal regulators to probe into the sufficiency of the security safeguards by Google.

Noting faults in Google's practices related to the so-called 'cloud computing' services, the Electronic Privacy Information Center (EPIC) Tuesday filed a complaint with the US Federal Trade Commission (FTC). The main flaw in the cloud computing services is that all the user-generated documents and other personal information is stockpiled on Google servers, rather than the personal computer of the users.

Known for focusing on privacy issues and civil liberties, the Washington, D. C.-based privacy group, has also asked the FTC to prevent Google from offering the contentious services till the time it puts the requisite safeguards in place.

Referring to the March 7 Google Docs glitch, EPIC Executive Director Marc Rotenberg said that the malfunction provided "ample" precedent for the FTC to initiate a probe. Rotenberg said: "The Google Docs data breach highlights the hazards of Google's inadequate security practices, as well as the risks of cloud computing services generally."

Meanwhile, Google has said that the bug in Google Docs - which caused the sharing of personal documents among users - had affected only 0.05 percent of all documents, and had been duly fixed.
