The U.K.'s Information Commissioner's Office is concerned about how companies are moving data into their cloud computing solutions, so ZDNet said they have released a set of guidelines for this reason, telling companies to review personal data they process to first decide if the data needs to be in the cloud or if it needs more protection.

"As a business, you are responsible for keeping your data safe," Dr. Simon Rice, ICO's technology policy advisor, said in  statement on Thursday. "You can outsource some of the processing of that data, as happens with cloud computing, but how that data is used and protected remains your responsibility."

ICO said that companies must inform end users of the cloud service processing arrangement they have, and make sure the provider has the best security measures in place. Guidelines say that while looking at the premises may be the best way to figure out how secure a provider is, not everyone may be willing to let customers in. This means businesses will have to do their own due diligence.

The Data Protection Act 1998 in the U.K. is the basis for many of the ICO's guidelines and relates to how they can be used with cloud computing solutions, as this law highlights how business information must be protected.
