37 Electronic Payment Processes - Secure Electronic Payments Secure electronic payments – when you make an online purchase on the Internet, your credit card info is vulnerable to interception by network sniffers ¦ SW that easily recognizes credit card number formats ¦ Several basic security measures are being used to solve this security problem. They include: ¦ Encrypt data passing between customer and merchant ¦ Encrypt the data passing between the customer and the company authorizing the credit card transaction ¦ Take sensitive information offline (cont-d) ¦
38 Electronic Payment Processes - Secure Electronic Payments (cont-d) Secure Socket Layer (SSL) – automatically encrypts data passing between your web browser and a merchant’s server. ¦ Digital Wallet – you add security software add-on modules to your web browser. This enables your browser to encrypt your credit card data in such a way that only the bank that authorizes credit card transactions for the merchant can see it. ¦ Secure Electronic Transaction standard (SET) – software encrypts a digital envelope of digital certificates specifying the payment details for each transaction. SET is expected to become the dominant standard for secure electronic payments on the Internet. ¦
