Online services and Security and privacy of data

To reduce the chances of information theft from users certain data security aspects will be identified in the below categories:

• Need to protect confidentiality of data:

Encryption is the main I.C.T. technique used to ensure the confidentiality of data in online systems.

• Shop security:

Public-key systems are used to encrypt information that is transmitted using the Internet for payment purposes.

• Online banking: There are three methods:

1. Transaction numbers (T.A.N.s), or in other words passwords used only once.
2. Asking the user to type only parts of their passwords.
3. Providing customers with a handheld chip and P.I.N. device which is capable of generating single-use passwords (in other words "two-factor authentication"/ "2.F.A.").

• Online shopping:

the customer should make sure that the data is being transmitted using either the secure socket layer (S.S.L.) or transport layer security (T.L.S.) protocols which are used in the encryption of messages between a client computer and a server.
