Electronic payment system
First Claim
1. An electronic payment system comprising:
- first payment means for making payments in electronic form, first processing means for generating electronic receipts corresponding to received payments, the first processing means being arranged to encrypt the electronic receipt to be generated or part of it, if necessary, with a public-key algorithm by using the payee'"'"'s private key as an encryption key, wherein an electronic receipt which is partly of completely encrypted does not contain unencrypted identification data on the payee, second processing means for receiving said receipts, the second processing means being arranged to decrypt a received receipt with a public-key algorithm by using the payee'"'"'s public key as a decryption key, and transfer means for transferring said receipts between the first and second processing means and the first payment means, wherein the first processing means are arranged to transfer the generated electronic receipts to the first payment means in response to the payments made by means of the transfer means, and the first payment means are arranged to transfer one or more of said receipts to the second processing means by means of the transfer means, and when transferring one or more of said receipts to the second processing means, the first payment means are arranged to transfer with the receipts only the payee'"'"'s identification data related to the receipts that the second processing means are entitled to decrypt.

Abstract
Equipment and method for acknowledging a transaction in an electronic payment system, comprising first processing means for providing electronic receipts corresponding to payments, second processing means for receiving said receipts, and transfer means for transferring said receipts between the first and second processing means. Said electronic receipt or part of it is encrypted with a public-key algorithm by using the payee'"'"'s private key as an encryption key, and a receipt is decrypted with a public-key algorithm by using the payee'"'"'s public key as s decryption key. If a recipient of the receipt wants to be convinced of the authenticity of the receipt, he decrypts the encryption by means of the payee'"'"'s public key. Digital encryption with the payee'"'"'s private key certifies the origin of the receipt undeniably. As long as the receipt is in encrypted form, it cannot be read without exactly knowing the payee, and counterfeiting of the receipt is impossible. An electronic receipt can be easily read and transferred between different destinations.

11. A method for acknowledging a transaction in an electronic payment system comprising first payment means for making payments in electronic form, first processing means for providing electronic receipts corresponding to payments, second processing means for receiving said receipts, and transfer means for transferring said receipts between said first and second processing means and the first payment means, the method comprising:
-
encrypting said electronic receipts or parts of them in the first processing means with a public-key algorithm by using the payee'"'"'s private key as an encryption key, wherein an electronic receipt which is partly or completely encrypted does not contain unencrypted identification data on the payee, transferring the encrypted electronic receipts from the first processing means to the first payment means, transferring one or more of said receipts from the first payment means to the second processing means in such a way that only the payee'"'"'s identification data related to the receipts that the second processing means are entitled to decrypt are transferred with the receipts, and decrypting receipts in the second processing means with a public-key algorithm by using the payee'"'"'s public key as a decryption key. - View Dependent Claims (12, 13, 14, 15)
