Abstract: A method and system for the dissemination of the profiles that a user has on the various online social networks, based on recognising a physical element and network software allowing any user of online social networks to disseminate all or part of the profiles they have on the various online social networks to which they belong effectively and selectively, based on identification of users via a string of graphic symbols.

Abstract: Method and system of communication that allow people unknown to each other who have visual contact, to communicate by sms or e-mail based on the identification of system users through the perception of codes of registered users, formed from the combination of graphic symbols that follow uniquely identifying coding rules for each user within the system, by use of a computer application that decodes said user codes and allows the delivery of messages between said users, ensuring maximum discretion during communication, both towards the rest of the environment and towards the user with whom one wishes to establish contact.
