What makes e-cash secure

The security that is used in e-cash is cryptographic algorithms where is a key to create a tamper proof e-cash which can be traces back to where it is being issued. The usage of the e-cash is anonymous which means the e-cash could not be traced back to find out who sent it.

Each of the e-cash is embedded with a serial number and the number will not be used again. E-cash also has threat prosecution where it’s the main security in order to prevent double spending. This is made possible due to the complicated two-part lock which provides the e-cash with anonymous security and informs when someone is attempting to double the spent cash.

E-Cash as a Payment Method

Before the user is able to use e-cash the user first have to create an account with the provider first. Once the provider has verified the identity of the user they will provide the user with a digital certificate which serves as a proof of identity to that user.

Once the user is identified using the digital certificate the bank will issue an e-currency to the customer according to the amount that is required by the user and the amount is then deducted from the users account. The user then can use the e-cash to make payment to merchant who are verified to prevent fraud and forgery.

Once the goods or service are received by the buyer the merchant then can present the e-cash to the issuing bank to deposit it into the merchant’s account.
