One of the break in allowed the criminal to get , social security numbers. At Georgia Tech an intruder was able to steal 57, credit card numbers.

Something similar happend at University of Texas in Austin when someone broke a server and got social security numbers and email addresses of more than 55, students, former students, and employees. George Mason was another school who was affected by someone breaking in and getting personal information. These breaks are very dangerous and make the people whose information was stolen very vulnerable to identity theft, credit card attacks and other issues.

People who were affected should immediately cancel credit cards, and check personal records to makes sure no harm was or is being done to them. Although this language is very useful, some recent security flaws have been found. Some issues with AJAX are that clients are able to send corrupt data and perform an attack.

Another risk is a user can do unauthorized privileges if there is no server-side protection. This obviously could cause a lot of problems if the wrong person is granted high access rights. Although communicating parties do not need to invest in a private network infrastructure, they have no control over the network used and no guaranteed standard of service.

The lack of interoperable implementations has been the main impediment to the deployment of VPNs to date [ 6 ]. Just as you wouldn't allow anybody to listen in to your telephone conversation, so you need to care for your Web browsing sessions and e-mail exchanges. For this purpose you need a firewall, designed to prevent damage to your system. Whether you are connected to NHSnet or the Internet the security threats to your data in transit are the same; data may be subject to loss, late delivery, damage, or attack.

Against loss or lateness, there is little the individual can do, but damage or attack can be dealt with. You should assume the wires or other network infrastructure could be got at--as indeed they can--and thus must give your data a metaphorical envelope to maintain its integrity and privacy.

This is precisely what cryptography can do. A popular technique for protecting messages in transit is so-called asymmetric public-key infrastructure PKI cryptography. Alice and Bob who wish to exchange messages each use an algorithm based on very large prime numbers to develop two separate but related numbers, by way of typing in a pass-phrase.

If Alice wishes to send a message to Bob, she finds his public key typically from a directory , writes her message, and encrypts addresses the data to Bob's public key, thus producing a unique set of digital data.

Bob receives this in encrypted form and uses his private key to extract the data back into Alice's original text message. This process is illustrated in Figure 1. In use, this is easier than it sounds, and confers integrity the data haven't been manipulated , authenticity the identity of the sender is known , nonrepudiation the data can't be disowned and privacy on the data. Any attempt to interfere or damage the contents messes up the mathematics, and the message becomes unintelligible, thus warning the recipient not to trust it.

Provided the verification of the identity of the key-holders is carried out in a dictatorial fashion, the origin authentication of the message is also assured. If only Alice knows the private phrase key to make an exchange work, then only Alice can have sent the message. As we move towards a browser-accessible type of electronic patient record there will arise a need to protect the exchange of data from leakage and attack.

A precedent has been set by the widespread practice of Internet banking and commerce, which out of necessity involves transmitting confidential information. It uses a symmetrical one-time electronic key that works between the browser and the server for as long as the connection is open. When the session ends, the encryption dies with it, and thus it depends largely on its length of key structure and short time of operation for its safety.

Assurance of identity authentication on the Web presently requires the use of a certificate supplied by a third party Certificate Authority, such as VeriSign Inc.

The process is illustrated in Fig. In the UK the Electronic Communications Act provides the legal framework for the recognition of digital signatures [ 8 ].
