Method for proof of transaction
First Claim
1. Method for proof of transactions in a digital network, especially on the internet, where the acceptance of a bid presented via a bid server takes place by means of the fact that a) a digital form is requested from the bid server (3) by a customer'"'"'s computer (1) connected to the network, b) the form is transmitted from the bid server (3) to the customer'"'"'s computer (1) and c) the form data entered in the form, which comprise the data required for acceptance of the bid, are sent back to an order acceptance server, characterised in that d) the form sent from the bid server (3) to the customer'"'"'s computer (1) contains the network address of a transaction proof server (4), e) the form data are sent from the customer'"'"'s computer (1) to the transaction proof server (4), f) the form data are provided with a digital time specification, g) at least one check digit code is generated for the form data and the digital time specification, and this check digit code is encoded with a key to form a time signature, and h) the form data are transmitted from the transaction proof server (4) together with the digital time specification and the time signature to the order acceptance server.

b) the form is transmitted from the bid server (3) to the customer'"'"'s computer (1) and
c) the form data entered in the form, which comprise the data required for acceptance of the bid, are sent back to an order acceptance server,
d) the form sent from the bid server (3) to the customer'"'"'s computer (1) contains the network address of a transaction proof server (4),
e) the form data are sent from the customer'"'"'s computer (1) to the transaction proof server (4),
f) the form data are provided with a digital time specification,
g) at least one check digit code is generated for the form data and the digital time specification, and this check digit code is encoded with a key to form a time signature, and
