AUTHENTICATION METHOD AND SYSTEM

摘要

A method and a system authenticate an identity of an entity or a user (16) transacting with a remotely accessible transaction host (10). A first message (32), encoded using a first transaction verification code, including a verification response address associated with the transaction host, is transmitted over a first communication channel (20) to a remote client device (18). A verification response number (address) is provided for communication from a remote communication device (22) with the transaction host over a second communication channel (26) with a second message (36) encoded by using a second transaction verification. The first and second transaction verification codes are compared. The identity of an entity or a user having transmitted the second message is authenticated, if the second message, received by the transaction host at the verification response address, has the second transaction verification code correspond to the first transaction verification code.

1. A method for authenticating the identity of an entity or a user transacting with a remotely accessible transaction host, wherein at the transaction host carried out are the steps of:
transmitting over a first communication channel a first message, including at least a verification response address associated with the transaction host, to a remote client device, said first message being encoded by using a first transaction verification code, and said verification response address being provided for communication from a remote communication device with the transaction host over a second communication channel; receiving a second message over the second communication channel from said remote communication device, said second message being encoded by using a second transaction verification code, the second transaction verification code having been transmitted to the verification response address; comparing the first and second transaction verification codes; and authenticating the identity of an entity or a user having transmitted said second message, if said second message was received by the transaction host at the verification response address and the first and second messages match at least in so far as the second transaction verification code used for encoding said second message corresponds to the first transaction verification code used for encoding said first message.
