anding over your credit card to a waiter or waitress in a restaurant, or to a petrol pump assistant may be a dangerous act. The worker may take your card into the back room and swipe the card through a skimming machine which copies the information held on the magnetic strip. This replica card can now be used to impersonate the victim with goods being bought by the criminal and being charged to the victim’s credit card.
However, the virtual world is also not a 100% safe environment. The network itself may not be safe giving rise to the problem of eavesdropping. The Internet is an open network thus it is not a safe medium for information transfer. An intranet is only marginally safer. Messages may also have to be routed across the globe. Unlike a traditional communication delivery system a limitless number of people may be able to intercept the communication. Finally, the Internet is not owned by anyone and thus it is very difficult to attach blame to one person/State/company.
Nevertheless, the public perception is that the virtual world is a much more lawless place than the real world and thus the virtual world is a more inherently unsafe environment. Thus, to encourage e-commerce, governments have to take action to overcome this reluctance to go online. This perception can be countered through legislative and non-legislative means. Non-legislative measures include technological security measures, consumer e英语论文网 【http://www.51lunwen.org】ducational programmes and the promulgation of Codes of Best Practice by business organisations. Laws can be enacted that engender confidence in online transactions. These laws may create two problems. Firstly, the law may not be technology neutral, since virtual transactions may be subjected to a stricter regulatory regime than those in the real world. Secondly, these strict laws that regulate virtual transactions may actually forestall the utilisation of new technology, that is the law may actually have the opposite effect of what the law was intended to achieve.
What are the Purposes of Formal Validation/Authentication Rules? GENERAL Evidential/Authenticity A signature acts to authenticate a written document by linking the signer with the signed document. The distinctive sign is attributed to the signer. Authentication is currently achieved in e-transactions through digital signatures and bio-metrics. In the future, quantum cryptography may be used which will be 100% secure and may render mathematical algorithms obsolete.
Ceremonial/Formal The physical act of signing is a significant act. Thus, the person signing is made aware of the gravity of their actions.
Affirmation/Authorisation/ Non-repudiation Appending a signature to a document expresses the signer's approval/authorisation of the contents of the document and signifies the intention o
