- To protect privates data the programmer can use encryption.The information such as address,phone number.name and the e-mail will be changed to codes,and the only way to open them is to decrypt the code to the original form and this will open when the information is needed and only the programmer himself knows how to decrypt.

- Use and maintain anti-virus software, a firewall, and anti-spyware software - Protect yourself against viruses and Trojan horses that may steal or modify the data on your own computer and leave you vulnerable by using anti-virus software and a firewall (see Understanding Anti-Virus Software and Understanding Firewalls for more information). Make sure to keep your virus definitions up to date. Spyware or adware hidden in software programs may also give attackers access to your data, so use a legitimate anti-spyware program to scan your computer and remove any of these files (see Recognizing and Avoiding Spyware for more information).
- Keep software, particularly your web browser, up to date - Install software updates so that attackers cannot take advantage of known problems or vulnerabilities (see Understanding Patches for more information).*mahmoodalqubtan all right reserved* Many operating systems offer automatic updates. If this option is available, you should enable it.
3-Online banking
- The PIN/TAN system where the PIN represents a password, used for the login and TANs representing one-time passwords to authenticate transactions. TANs can be distributed in different ways, the most popular one is to send a list of TANs *mahmoodalqubtan all right reserved* to the online banking user by postal letter. The most secure way of using TANs is to generate them by need using a security token. These token generated TANs depend on the time and a unique secret, stored in the security token (two-factor authentication or 2FA). Usually online banking with PIN/TAN is done via a web browser using SSL secured connections, so that there is no additional encryption needed.
- Another way to provide TANs to an online banking user is to send the TAN of the current bank transaction to the user's (GSM) mobile phone via SMS. The SMS text usually quotes the transaction amount and details, the TAN is only valid for a short period of time. Especially in Germany, Austria and The Netherlands, many banks have adopted this "SMS TAN" service as it is considered very secure.
- Signature based online banking where all transactions are signed and encrypted digitally. The Keys for the signature generation and encryption can be stored on smartcards or any memory medium, depending on the concrete implementation.

Look For Signs of Security
Identify security clues such as a lock image at the bottom of your browser or a URL that begins with https://. These signs indicate that only you and the merchant can view your payment information.

Never Send Payment Information via Email
Information that travels over the Internet (such as email) *mahmoodalqubtan all right reserved* is not fully protected from being read by outside parties. Most reputable merchant sites use encryption technologies that will protect your private data from being accessed by others as you conduct an Online transaction.
