Google has received 12,000 requests from people seeking to be "forgotten" by the world's leading search engine on the first day it offered the service, a company spokesman says.

The requests, submitted on Friday, came after Google set up an online form to allow Europeans to request the removal of results about them from internet searches.

The service is not available in Australia.

The number confirms earlier estimates given by the German daily Der Spiegel and reported in other media.

Earlier in May the European Court of Justice ruled that individuals have the right to have links to information about them deleted from searches in certain circumstances, such as if the data is outdated or inaccurate.

Google said that each request would be examined individually to gauge whether it met the ruling's criteria.

The US-based internet giant declined to estimate how long it might take for the links to disappear, saying factors such as whether requests are clear-cut will affect how long it takes.

The ruling on the right to be forgotten comes amid growing concern in Europe about individuals' ability to protect their personal data and manage their reputations online.
The case was originally launched by a Spanish man who objected to old articles emerging from a Google search of his name.

When Mario Costeja Gonzalez googled his name the search engine threw up 16-year-old articles about his home being repossessed, something he would rather have the world forget.

After the court verdict European justice commissioner Viviane Reding said the decision vindicated the European Union's efforts to toughen up privacy rules.

Google said the outcome of the court case was disappointing.
