Abstract: Systems and methods are provided for location tracking and filtering or hiding electronic communications. In one implementation, a method is provided for location tracking for electronic communications. The method includes receiving a location ID for a location from a user who desires to follow the location within a social networking environment, and associating the location ID with the user. The method also includes providing instructions to display a representation of the location in a list of the user's contacts.

Abstract: Systems and methods are provided for filtering electronic communications. One exemplary method includes receiving a first message directed to a user, the first message including a plurality of messaging data; and receiving from the user a selection of the messaging data within the first message. The method further includes adding the selected messaging data to a database in relation to one or more contacts of the user, and receiving a second message directed to the user from at least one of the one or more contacts. The method further includes scanning the second message for the selected messaging data, and filtering, with at least one processor, the second message from delivery to the user if the second message contains the selected messaging data.

Abstract: A secure electronic messaging system permits communication between registered users, with the assistance of a key server. The system requires a recipient to submit key retrieval information to a key server, and obtain decryption key information. The decryption key information is necessary for the recipient to form the decryption key which is used to read a message encrypted by the sender. The decryption key information may be an encrypted version of a decryption key, or portions thereof, or may be portions of an unencrypted version of a decryption key, among others. Typically, the key retrieval information may either be sent to the recipient by the sender, or may be generated by the recipient, based on information sent by the sender.
