It protects the confidentiality of the information by encrypting the information.
2. Data integrity is guaranteed by cryptography as the receiver is ensured that the data received has not been tampered with during transmission as digital keys are used to confirm that what is received is real and from the intended sender.
3. Cryptography also supports the availability of data by guaranteeing that individuals with the right permission can use systems and retrieve data in a dependable and timely manner.]]> 2022-09-03 03:20:24 UTC https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281313885 rach3246 https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281345050 1.

Electronic money is mostly utilized for electronic transactions because of how convenient it is, even if its value is supported by fiat currency and may therefore be converted into a physical, tangible form.]]> 2022-09-04 02:03:53 UTC https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281726997 rach3246 https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281728050 Blind signature techniques are the foundation of anonymous applications, which conceal the customer's identity. Based on more open-ended varieties of signature systems, identified spending schemes make the customer's identity known. There are also some hybrid approaches where payments can be anonymous with respect to the merchant but not the bank ;or anonymous to everyone, but traceable (a sequence of purchases can be related, but not linked directly to the spender’s identity).]]> 2022-09-04 02:07:47 UTC https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281728050 rach3246 https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281728706 Public-key encryption can guarantee confidentiality, digital signatures can take the place of handwritten signatures or credit-card authorizations, and encryption is used in electronic money schemes to secure traditional transaction data such account numbers and transaction amounts.]]> 2022-09-04 02:09:15 UTC https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281728706 rach3246 https://padlet.com/rach3246/9nq5h9exaidfpkau/wish/2281729682 1.
