Abstract: Systems and methods that regulate range of access to personal information of a mobile unit's owner. The access control component can designate granularity for access levels and/or a spectrum of access modes—(as opposed to a binary choice of full access or no access at all). Such access can be based on a spectrum and/or discrete trust relationship between the owner and user of the mobile unit. A profile definition component can exploit an owner's trust relationships to designate levels of security. The profile definition component can further define a profile based on a set of applications, such as entertainment mode, browser mode, and the like.

Abstract: Various technologies pertaining to authenticating a password in a manner that prevents offline dictionary attacks are described. A protected module, which can be a hardware security module, a trusted platform module, or the like, is in communication with an authentication server. The protected module comprises a key that is restricted to the protected module. The key is employed in connection with authenticating the password on the protected module.

Abstract: A current prefix character string representing a prefix of a proposed password may be obtained from a user input device. A prediction of a most likely next character of the proposed password may be determined, based on applying a set of heuristics to the current prefix character string. A response indicating an impact on a security strength of the proposed password may be determined, based on a selection of the predicted most likely next character.

Abstract: The access control management technique described herein manages access control to one or more resources. Rather than mapping individuals or groups to permissions, the technique maps each permission (the right to perform an action on a resource) to the list of authorized principals (the users and groups authorized to perform the action on the resource). These lists are written in text form just as one would write the list of recipients (individuals and groups) of an email composition window. The technique also provides various operations to allow a user to manage the list of authorized principals and the authorizations assigned to a principal to access the resource/action pair.
