A senior European Union (EU) official has warned the three leading search engines to get inline with EU suggestions and delete users' browsing history more quickly.
The chairman of the Article 29 Working Party (WP29), Jacob Kohnstamm, has written letters to Google, Yahoo and Microsoft conceding that improvements had been made but they needed to go further to protect their user's privacy.
The companies currently hold IP addresses in the search query log files for nine months but Kohnstamm wants them to cut this down to six months.
He also wants "a reduction of the possibility to identify users in the search logs and the creation of an external audit process to reassure users that you are delivering on your privacy promises, i.e. by involving an independent and external auditing entity."
In his letter to Google Kohnstamm wrote: "Fair and lawful processing of personal data by search engines is becoming more and more crucial due to the explosion and proliferation of audiovisual data (digital images, audio and video content) and the increasing use of geolocation on the internet."
"Given the predominant role of the Google search engine in the daily lives of all citizens of the European information society, the apparent lack of focus on privacy in this area is concerning."
However, Google thinks it has performed much better than it has been given creit for by Kohnstamm.
A spokesperson from the company told IT PRO: "Google was the first search engine to reduce the time it stores search logs, and the first to anonymise them."
"We develop our policies based on what provides the best experience for users both in terms of respect for their privacy and the quality and security of our services. Our current retention policy represents the most responsible balance between these two important concerns."
Microsoft has taken a different tact and said it will abide by the WP29's recommendations.
Thomas Myrup Kristensen, senior EU policy director at the company, said in a statement: "Microsoft will delete the entire IP address from search queries at six months in keeping with the Working Party's recommendation."
Before he finished, Kristensen took a dig at Google, adding: "We look forward to the continued dialogue with the WP29 on all aspects of compliance and encourage them to ensure that the whole search market, including the 95 per cent that in some markets is held by a single company, is held to a single standard."
Privacy is becoming an increasingly prominent topic in the internet world. Facebook has been hitting the headlines all week regarding its privacy flaws and attempts to bring in new controls whilst Google has faced months of criticism over its Buzz social network.
We contacted Yahoo for comment as well but it had not responded to our request at the time of publication.
