Abstract
E-commerce web page forms contain an encrypted and encoded string, which contains basic information about a product for sale on the web page. Optional product data (e.g. size, color) is selected by an online shopper and transmitted with the basic information when the form is submitted to a cash register server. The form may also contain store ID information which is used to the look up the secret string needed to decrypt the product information. A method for generating the encrypted encoded string for use in the web page is described. Confidentiality is provided with regard to purchases over the Internet.
