Claim:
1. A method for securing data using a dynamic hash, the method comprising: creating a first hash input including a first set of data fields selected from a first collection of data, the first set of data fields including a first data field obtained from a consumer input device by a point of data entry device, a second data field obtained from the consumer input device by the point of data entry device and a third data field obtained from the point of data entry device, the first data field including an account identifier obtained from the consumer input device, the second data field including sensitive data obtained from the consumer input device, the third data field including data having a value determined independent of the consumer input device; performing a hash operation on the first hash input to create a first hash output; assembling a second collection of data including (i) at least a portion of said first hash output and (ii) a second set of data fields selected from the first collection of data, the second set of data fields partially incorporating the first set of data fields at least in part by including the first data field obtained from the consumer input device and the third data field obtained from the point of data entry device and being distinct with respect to the first set of data fields at least in part by excluding the second data field obtained from the consumer input device; and securely communicating the sensitive data obtained from the consumer input device to the remote destination at least in part by transmitting the second collection of data over a network to a remote destination; wherein the second collection of data is assembled for each of a plurality of transactions with respect to an account identified by the account identifier and contents of said at least a portion of said first hash output changes for each of the plurality of transactions.
