An unregistered requestor requests access to confidential information of an individual stored at a computer. In one embodiment, the requestor is authenticated by the computer using at least two authentication tests. When the requestor is authenticated, the computer determines access permission for the requestor based on information provided from the requestor, and provides, to the requestor, access to the confidential information of the individual based on the access permission. In another embodiment, the computer presents a series of challenges to the requestor, and if any of the challenges is passed, access is granted.
