ABSTRACT
As discussed in previous chapters, encryption is used to determine identity and verify electronic signatures. Another area where encryption or digital signatures may give rise to practical problems is data security and privacy protection. For example in B2C transactions an online retailer might have a database of information about its customers’ personal details and their history of transactions. In B2B transactions an international trading company might have its business partners’ bank details and business strategies in their computer servers after issuing Electronic Bills of Lading and Electronic Letters of Credit. So what will happen:
a if a third party steals the information; or b if the database owner sells the information to the third party?
