Topic 10 Questions

Topic 10: Trust
1.    What is meant by the following statements?
i.              Trust is not associative
Trust is not symmetric when buying or selling products on the internet, this is because a seller will only has to wait for a buy to place the money in there account before sending out the goods and because of this there is no trust in the relationship, the seller could not send the product.

ii.             Trust is not transitive
This means that you can refer customers to people whom you trust but it does not necessarily mean that they themselves will trust that person.
iii.            Trust is always between exactly two parties
This makes a point of trust being between 2 parties as a whole rather than trust being between individuals. This allows an individual party to trust a collection of individuals in a party.
                                                           
iv.           Trust will involve either direct trust or recommended trust
This means
2.    a) Have a look at the following websites. What are some of the elements that have been incorporated to increase your trust in the sites? If there are also some aspects which decrease your level of trust, describe them as well.
i.              http://www.eBay.com.au
You have to be registered before you can sell any goods. They also allow ratings for each seller so a potential customer can see all the reviews based on that seller.
ii.             http://www.anz.com.au
The bank provides a lot of precautious such as;
-          constant reminder to change passwords regularly
-          security and privacy statements
-          the use and disclosure of information
-          Record of IP addresses
(ANZ, 2010)
iii.            http://thinkgeek.com
Thinkgeek.com uses the following forms of security that users can implement and are more willing to trust them:

· 128-bit encryption to and from the servers and web browser.
· Credit card numbers are not stored in our database. We keep on file only the last 5 digits in cases where we need to verify the card that was used.
· Once the information is transmitted to our servers for processing, we use even stronger encryption in the back end to transmit the request to our payment processor to verify the credit card and place an authorization for the order total.
· If the authorization, address verification and risk assessment all clear, the order is accepted and a one-time unique ID is associated with the order for purposes of billing the previous authorization. This ID cannot be used to place further authorizations or bill more than the original auth. It contains no identifiable link to the credit card number.
· Once that ID has been used to bill the order (which happens only once the order begins shipping), it is no longer valid and cannot be used to authorize or bill again

iv.           http://paypal.com.au

b) Find a website yourself that you think looks untrustworthy
