Abstract: Disclosed are methods, systems, and computer program products for identifying sensitive application-layer data and controlling transmission of the data in a network. According to one method, sensitive data in a system resource is identified at an application layer. A packetization of the identified sensitive data is detected. A flag indicative of the presence of sensitive data is inserted in a packet having at least a portion of the identified sensitive data in response to identifying the sensitive data and detecting the packetization. The flag is inserted in a portion of the packet corresponding to a layer other than the application layer. Transmission of the packet is controlled in a network based on the flag.

Abstract: Associating a network packet with biometric information for a user includes identifying biometric identification information for a user of a network device, including an identifier of the biometric identification information in at least one of a header and a trailer of a network packet without including biometric identification information in a payload of the network packet, and sending the packet via a network, wherein the identifier identifies the network packet as having originated from the user.

Abstract: Presence information for an object in a digital image is determined. An identifier associated with at least one object depicted in the image is sufficient to determine presence information from at least one of a presence application and a presence roster list is used to subscribe to presence information associated with the at least one object via a presence service. Presence information for the at least one object is determined based on the identifier from the at least one of a presence application and a presence roster list. An action related to the object is performed using the determined presence information.

Abstract: Presence information for an object in a digital image is determined. An identifier associated with at least one object depicted in the image is allowed to be stored as image metadata. The identifier is sufficient to determine presence information from at least one of a presence application and a presence roster list. Presence information for the at least one object is determined based on the identifier from the at least one of a presence application and a presence roster list. An action related to the object is performed using the determined presence information.

Abstract: Methods, systems, and computer program products for determining an originator of a network packet using biometric information are disclosed. A network packet is received from a network device. A header or a trailer of the network packet is analyzed to determine whether the header or trailer includes an identifier of biometric identification information of a network user. The network packet is identified as having originated from the network user if the header or trailer includes the identifier of biometric identification information of the network user. Identifying the network packet as having originated from the network user does not require reading a payload of the packet.

Abstract: Methods, systems, and computer program products for associating an originator of a network packet with the network packet using biometric information are disclosed. According to one method, biometric identification information is identified for a network user. The identified biometric identification information is associated with a header or a trailer of a network packet originated by the network user. The network packet may be sent over a network.

Abstract: The present invention provides a computer-implemented method and system for associating presence information with a digital image. Aspects of the preferred embodiment include allowing an identifier associated with at least one object depicted in the image to be stored as image metadata; using the identifier to associate presence information with the at least one object; and performing an action related to the object using the associated presence information.
