Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new paradigms of computing and communications new data security challenges arise. Existing data protection mechanisms, such as encryption, have failed to prevent data theft attacks, especially those perpetrated by a member of the cloud provider. We propose a different approach to securing data in the cloud using offensive lure technology. We monitor access to data in the cloud and detect patterns of access to abnormal data. When unauthorized access is suspected and then verified through challenge questions, we launch a misinformation attack by returning large amounts of lure information to the attacker. This protects against misuse of the user's actual data. Experiments carried out in a local file provide evidence that this approach can provide unprecedented levels of user data security in a cloud environment.
