Abstract
The present disclosure includes systems and methods for providing instant messaging communication between users via a communication network. Instant messaging clients are executed at user devices of a first and second user. A data message is transmitted from the instant messaging client at the user device of the first user to the instant messaging client at the user device of the second user, the data message having a content portion and at least one associated attribute that is cryptographically generated. The cryptographic attribute plus any additional first user attributes irrefutably binds the ID of the first user to the message information content to form an irrevocable message. The availability of at least one user-selectable function by the instant messaging client at the user device of the second user is controllable, based on the at least one associated attribute.
