Question

write short note on (a)digital cash (b) safety and security of transaction​

Answer 1

Explanation:

Digital cash is a system of purchasing cash credits in relatively small amounts, storing the credits in your computer, and then spending them when making electronic purchases over the Internet. Theoretically, digital cash could be spent in very small increments, such as tenths of a cent (U.S.) or less.

In order to ensure security and safety of e-commerce, the following points need to be strengthened : (i) Authentication : The sender of a document must be identified precisely and without any possibility of fraud. (ii) Confidentiality : The contents of a message may not be carried by unauthorised parties.
