Patent 8176533 was granted and assigned to Oracle on May, 2012 by the United States Patent and Trademark Office.
An authentication mechanism is provided to authenticate both client and user of a portable computing device when the user causes a client to request a protected resource on the portable computing device. Upon receiving a request a protected resource by the client, the authentication mechanism determines which authentication method is specified for authentication of the client, and authenticates the client accordingly. Upon a determination that the client is authentic, the authentication mechanism invokes a user interface that is separate and distinct from the client to solicit input from the user. Based on the input solicited from the user, the authentication mechanism determines whether the user is an authentic user of the portable computing device. If it is determined that the user is an authentic user, the authentication mechanism determines based on an indication from the user whether the client should be authorized to access the protected resource requested.
