Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accessing at least one persona that includes a unique identifier that is at least partly based on a first user's device-identifier data and the first user's network-participation data; verifying the persona by comparing the first user's device-identifier data and the first user's network-participation data of the unique identifier to a second user's device-identifier data and the second user's network-participation data; and presenting the persona in response to a request for personal information.

Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accepting at least one persona from a party to a transaction; evaluating the transaction; and negotiating receipt of at least one different persona from the party to the transaction at least partly based on an evaluation of the transaction.

Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accepting at least one request for personal information from a party to a transaction; evaluating the transaction; and negotiating presentation of at least one persona to the party to the transaction at least partly based on an evaluation of the transaction.

Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accepting at least one email communication from at least one member of a network; disambiguating the at least one search term including associating the at least one search term with at least one of network-participation identifier data or device-identifier data; and presenting the sender profile in association with the at least one email communication.

Abstract: Structures and protocols are presented for facilitating a search partly based on a movement status of a search-capable device or on a position of a person's limb or on an association with another search-capable device.

Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accepting from a user identifier encryption entity at least one encrypted identifier corresponding to a user having at least one instance of data for encryption; encrypting the at least one instance of data to produce level-one-encrypted data; associating the at least one encrypted identifier with the level-one-encrypted data, wherein a level-one decryption key for the level-one-encrypted data is inaccessible to the user identifier encryption entity; and transmitting the level-one-encrypted data and associated encrypted identifier.

Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accepting at least one indication of an interaction involving at least one member of a network; creating a persona corresponding to the at least one member of a network, wherein the persona is at least partly based on the indication of an interaction; and presenting the persona for use in the interaction involving the at least one member of the network.

Abstract: Methods, apparatuses, computer program products, devices and systems are described that carry out accepting device-identifier data corresponding to at least one communication device; accepting network-participation identifier data associated with a verified real-world user associated with the at least one communication device; and assigning a unique identifier at least partly based on the device-identifier data and the network-participation identifier data.
