Abstract: A first executable program on a computer system is enabled to exchange communications with a second executable program on the computer system by determining that the first executable program requests to exchange information with the second executable program, using the second executable program to challenge the first executable program for a digital certificate, and using the second executable program to exchange information with the first executable program when the digital certificate is verified.

Abstract: Separations or images relating to film or other fields may be registered using a variety of features, such as, for example: (1) correcting one or more film distortions; (2) automatically determining a transformation to reduce a film distortion; (3) applying multiple criteria of merit to a set of features to determine a set of features to use in determining a transformation; (4) determining transformations for areas in an image or a separation in a radial order; (5) comparing areas in images or separations by weighting feature pixels differently than non-feature pixels; (6) determining distortion values for transformations by applying a partial distortion measure and/or using a spiral search configuration; (7) determining transformations by using different sets of features to determine corresponding transformation parameters in an iterative manner; and (8) applying a feathering technique to neighboring areas within an image or separation.

Abstract: A first content selection stored on a portable media device is associated with a first tag. In addition, a second tag that is associated with a second content selection and that indicates that supplemental content related to the second content selection is stored on a peer device is accessed from a peer device. The first tag is compared to the second tag, and, if a commonality shared by the first content selection and the second content selection is identified, an exchange of the supplemental content from the peer device to the portable media device is initiated.

Abstract: Systems and methods are provided for determining in real-time geographic areas having a threshold level of content consumption and deploying dynamic geo-fences to contain these geographic areas. These dynamic geo-fences provide a means for timing message notifications in order to optimize the chances of delivering targeted content to a mobile device user based on the current geographic location of the user's device relative to a threshold level of content consumption area. As mobile device users may be more likely to launch a client application in a place where other users are currently consuming content, a general message notification sent to the user's device located in a dynamic geo-fence created based on real-time content consumption, may increase the likelihood that the user will launch the client application and thereby, allow targeted content to be delivered to the user's mobile device.

Further, the simplified messaging interface may be used in conjunction with a standard messaging interface.

Abstract: An initialization vector (IV) is employed to decrypt a block of a stream that has been encrypted with Cypher Block Chaining (CBC) encryption, without requiring decryption of previous blocks within the stream. For example, a listener who accesses a distribution point to retrieve encrypted content authenticates himself to an application server that regulates access to encrypted content on the distribution point, and responsively receives a key. The listener then requests access to a reference point within the encrypted content stream somewhere after its beginning (e.g., using preview clips). The distribution point relates the reference point to a corresponding block of the encrypted stream, and identifies an IV previously used for encryption of that block. The distribution point provides the associated encrypted block of content and the IV to the listener to enable mid-stream rendering of the encrypted content, without requiring the listener to decrypt previous blocks within the encrypted stream.

Abstract: Systems and methods are provided for timing message notifications to be provided to mobile device users based on their respective geographic locations with respect to a targeted content area. The timing of message notifications may be controlled in order to optimize the chances of delivering targeted content to a mobile device user based on the current geographic location of the user's device relative to a targeted content area. As the particular client application may not be actively executing at a time when the user's device happen to be located within a targeted content area, a general message notification sent to the user's device, which may be displayed at any time, may increase the likelihood that the user will launch the client application when it is not already executing at the device and thereby, allow targeted content to be delivered to the user's mobile device at the appropriate time and location.

Abstract: According to one aspect of the present disclosure, a computer-implemented method is provided for generating a reputation record and filtering electronic messages, each reputation record including a reputation score and a reputation key. The method includes receiving at least one incoming event notification, including a reputation key; determining, based on the reputation key, whether a corresponding reputation record exists; creating a new reputation record if the corresponding reputation record does not exist; determining a trust determination function based on the incoming event notification; calculating a reputation score based on the determined trust determination function, the incoming event notification, and an attribute associated with the reputation key; storing the calculated reputation score along with the reputation key in either the new reputation record or the corresponding reputation record; and filtering one or more electronic messages based on the calculated reputation score.

Abstract: Enabling a user to perceive map or route information including a status includes enabling a first user to perceive one or more features of a map and receiving condition information that reflects a condition perceived by the first user as existing relative to the one or more features based on input from the first user. Also, enabling a user to perceive map or route information includes receiving a request for a route from a second user and determining a response to the request for the route including the route based on the condition information received from the first user related to the one or more features. Further, enabling a user to perceive map or route information includes enabling the second user to perceive the route based on receipt of the response.

Abstract: A page structure may be used to begin validation of an embedded resource prior to the time a browser issues a request to validate the embedded resource. A page structure includes information indicating one or more embedded resources in the web page and, in some implementations, its corresponding cache characteristics. The page structure may be used to generate a validation message that indicates resources to be validated. The validation message may be sent to a server at substantially the same time that the browser begins rendering the web page. The server can then begin validating the resources indicated in the validation message by sending validation requests to an origin or other server storing the embedded resources. The server then may send the validation responses back to the client computer executing the browser so that the validation responses can be used to satisfy corresponding validation requests generated by the browser.

Abstract: A mood state may be modeled using mood information for a content selection (e.g., a digitally-encoded song) and/or by using mood information determined by how a user is interacting with a media player. For example, a playlist engine on a host may determine that a particular song is associated with an uplifting mood, thus determining that a user who has selected that particular song currently is in an uplifting mood, and correspondingly may select additional songs and advertisements consistent with, or responsive to, the uplifting mood. Mood information also may be used to present a mood state of users (e.g., co-users) in a network for display in a graphical user interface (GUI). For example, a user's screen name appearing in an America Online (AOL) Instant Messenger's Buddy List may indicate a determined user's mood, such as “happy”, “sad”, “silly”, or “angry.

Abstract: Systems and methods are provided for managing workloads across multiple resources in a distributed computing system. A data traffic flow between a source device and each of a plurality of target devices within the distributed computing system is monitored. A load state of each of the plurality of target devices is determined based on the monitored data traffic flow. Upon detecting a resource constraint for at least one of the plurality of target devices, at least a portion of the data traffic flow between the source device and the resource-constrained target device is adjusted such that the device operates at a reduced load state. The data traffic flow to the particular target device may be readjusted so as to restore its load state to a default or predetermined operating level once the resource constrained has been resolved.

In one implementation, the chat session or data feed relates to content provided by members of a group or social network. In other implementations, the content related to chat session or data feed is provided by members of the general public.

Abstract: Systems and methods are provided for increasing sales profits by dynamically determining a promotion associated with a coupon. The promotion may be determined and delivered to a mobile device once the mobile device is in a geographic location associated with the coupon. By allowing advertisers to change or decide promotions in real-time, demand may be smoothed and profits may be maximized. When the mobile device is in the location associated with the coupons, advertisers can use a variety of factors including location, time of day, current sales or redemption data, or information known about the mobile device to set or adjust an ideal promotion for the current situation.
