Abstract: A centralized account reputation system differentiates between illegitimate users and legitimate users using reputation scores associated with the users' online accounts. The system restricts the access of illegitimate users to certain network services while minimizing its negative effects on legitimate users. The system can manage the life cycle of an online account, considering data about the account that is obtained throughout the account network to compute the online account reputation score and allocating access to network services based on the online account reputation score. For example, a reputation score may be embedded in a security token that can be accessed by multiple services on the account network, so that each service can determine the appropriate level of access to be granted to the associated user account based on the reputation score. Various types of online account behavior over time can improve or diminish the online account's reputation.

Abstract: An integration approach to improve electromigration resistance in a semiconductor device is described. A via hole is formed in a stack that includes an upper dielectric layer, a middle TiN ARC, and a lower first metal layer and is filled with a conformal diffusion barrier layer and a second metal layer. A key feature is that the etch process can be selected to vary the shape and location of the via bottom. A round or partially rounded bottom is formed in the first metal layer to reduce mechanical stress near the diffusion barrier layer. On the other hand, a flat bottom which stops on or in the TiN ARC is selected when exposure of the first metal layer to subsequent processing steps is a primary concern. Electromigration resistance is found to be lower than for a via structure with a flat bottom formed in a first metal layer.

Abstract: A federated realm discovery system within a federation determines a “home” realm associated with a portion of the user's credentials before the user's secret information (such as a password) is passed to a non-home realm. A login user interface accepts a user identifier and, based on the user identifier, can use various methods to identify an account authority service within the federation that can authenticate the user. In one method, a realm list of the user device can be used to direct the login to the appropriate home realm of the user. In another method, an account authority service in a non-home realm can look up the user's home realm and provide realm information directing the user device to login at the home realm.
