Electronic transaction signing is an important process as the volume and value of electronic transactions is increasing. There is a need for a secure yet convenient process to authorize the electronic transaction. On the other hand, current solutions often have complex deployment requirements, inclusive of a predefined communication channel to be established between the signer client and the signature requestor server. This paper proposed a multi-channel solution in which the signer client is capable of delivering these transaction-specific signatures to the signature requestor server, by means of different communication channels. |
