Abstract
Systems, methods, and software for providing digital security to a child message transmitted from a mobile device to a messaging server, where the mobile device typically does not transmit the parent message with the child message to the messaging server. Whether to apply digital security, such as encryption or a digital signature, or both, is determined, and if the mobile device does not include a complete copy of a parent message for insertion into the child message, the mobile device selectively downloads the parent message from the messaging server prior to the computation of a digital signature or prior to encryption. The systems and methods may also provide a check of the child message size, when the child message includes inserted parent content, to ensure that the child message does not exceed any prescribed limits on message size.

40. A method for providing digital security to a message transmitted from a mobile device, wherein the message is associated with a previously received message, at least a portion of said previously received message having been received and stored at the mobile device, the method comprising:
-
generating a message; determining whether a complete copy of the previously received message is stored at the mobile device; downloading a complete copy of the previously received message while the message is being generated if the complete copy of the previously received message is not stored at the mobile device; inserting content from the previously received message into the message; determining whether a body of the message comprising inserted content from the previously received message exceeds a predetermined size limit, and truncating the body of the message prior to transmission of the message, if the body of the message exceeds said size limit, such that the truncated body of the message comprises a portion of the inserted content from the previously received message; applying a digital signature to the message; and transmitting the message.
