A private network system operates over a public network to provide an asymmetric service to members with information from other members and non-members. The system includes central servers and databases connected via the public network to client systems of public network users. The users may be members who communicate with a private protocol or non-members who communicate with the public protocol. A process for the private service includes communication of information between users via the private service servers. The private service server implements the private service, which includes a viral engine for network deployment. Features of the viral engine include genetic algorithms, data mining, personalization, frictionless service setup, user maximization, and member-controlled privacy. A sample setup process and contact update wizard that include several viral engine features are described.

A method for communicating location information to a device includes receiving, at a computer system that implements a social networking service, location information that represents a geographic location of a device associated with a first user; associating, by the computer system, the received location information with a profile associated with the first user; and sending, from the computer system to a device associated with a second user, a message that is generated based at least in part on the location information.

A system and method for performing email processing at multiple stages along an email delivery chain. A first embodiment uses an email filter to receive information about an email message from a message transfer agent and then perform limited email pre-processing on the email message. The email filter then stores instructions and data such as the results from the email pre-processing into an internet email header added to the email message. The instructions and data placed into the email header may be encrypted for privacy and security. A later email program may extract the instructions and data from the internet email header and continue the email processing. One disclosed application of the multi-stage email processing system is email authentication.

A system and method displays lists of users or messages in segments, with some segments showing messages or users believed to be more relevant to the user than others on the list.

An interface element connected to a device and a security die-chip are fabricated in a single package. The security die-chip may provide a security authentication function to the interface element that does not have the security authentication function. The security die-chip may include a physically unclonable function (PUF) to provide a private key, and a hardware security module to perform encryption and decryption using the private key.

Disclosed herein are system, method, and computer program product embodiments for a dynamic email content engine. An embodiment operates by selecting a subscriber record from a database. The embodiment adds a first content item to a content pool based on a first rule in a set of rules, wherein the first rule is applied based on a characteristic of the content item or a persona record assigned to the subscriber record. The embodiments adds a second content item to the content pool based on a second rule in the set of rules. The embodiment ranks the first content item and the second content item in the content pool based on a first priority value and a second priority value. The embodiment assigns the first content item to the subscriber record based on the ranking.

A measure of influence of a sender entity is determined for a message receiving entity based at least in part on an analysis of previous electronic messages sent by the sender entity. An electronic message associated with the sender entity is received. The measure of influence of the sender entity is utilized to determine a security risk associated with the received electronic message.

A method for facilitating job introductions between candidates and employers for one or more job listings in an online system is disclosed. The method includes accessing, by the system, a completed form containing candidate contact information associated with a selected job listing. The method further includes determining employer contact information based on the selected job listing and transmitting an electronic communication introducing the candidate and employer.

A mobile device, such as a cellular telephone or a personal digital assistant (PDA), stores first personal data, such as any one or more of image, video, and audio data. The mobile device transmits the first personal data over a first wide area network (WAN) to a personal server.

A collaborative communication system that includes a plurality of endpoints and interconnecting nodes configured to communicate via messages over interconnecting channels. Each of the plurality of endpoints and/or interconnecting nodes can determine whether to apply protection to the messages on a per message basis and/or base on the interconnecting channel being used. Thus, a balance between adequate protection and use of system resources and bandwidth can be maintained.
