An intended recipient of the forwarding signature can verify that the forwarding signature corresponds to the message, but, can neither derive the original digital signature nor generate a new forwarding signature for a different parameter. Generation and verification of the forwarding signature is accomplished with access to the public key of a public/private cryptographic key pair, the original signed message, and the predetermined parameter. Access to the private key is not needed.

Compound order handling in an anonymous trading system
Joint execution type compound orders can be processed in an anonymous trading system comprising a plurality of broker nodes each of which includes an order matching functionality and a market distribution functionality. Trader agent nodes are connected to a number of dealer terminals grouped in trading floors and also to a broker node.

Method and system for music distribution
Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment.
