Secure Electronic Transaction is not a software package, but instead an industry standard set up by leading credit card vendors, Visa and Master Card, to ensure online transactions. Secure Electronic Transaction gives credit card purchases made over the internet extra layers of security that would ensure the customers data security at all times. In fact security would be higher than that of a traditional brick and mortar business, since no actual people would see the credit card numbers.Companies that desire more than just secure credit card transactions there are other methods of encryption for all the data they transfer, such as Public Key Infrastructure. Public Key Infrastructure would be especially beneficially for conducting business-to-business transactions. Public Key Infrastructure is essentially a digital signature that is structurally attached to an electronic document. The digital signature encases the document or file with a layer of security that follows the document. Digitally signing e-documents and files provides proof of identity of the individual who created the document and at the same time binds the document to him, thereby preventing that individual from denying association with such a document or file at any point in the future....
