Sections dealing with the offences of violation of information a privacy and damage to information /informational systems are too broadly worded, which may lead to confusion. International aspects of e-commerce such as recognition of the foreign certificates and electronic signatures etc. are missing.

How lack of trust barrier can be overcome or minimized? Discuss it briefly

Lack of Trust

It is very important for online businesses to establish trusting relationships with their customers like in the physical world where companies ensure that customers know who they are. However, it is difficult to build trust because
a kind of anonymity exists for companies trying to establish web presence. Lack of trust barrier can be overcome or minimized:

A plan for establishing credibility of an online business is extremely crucial for its success.
In this behalf, attention to the needs of the site visitors is very
important while designing the web site, since it can be helpful in building trust with customers.  For instance, there should be easy to find web pages that answer questions of the visitors.
Note that companies with established brands can build trust for
online business more quickly as compared to a new company/business without reputation, since a brand conveys expectations about how the online business would behave. For example, how the seller online business

Question No: 39     (Marks: 5 )

Differentiate between Cyber squatting and concurrent use with
example.  P: 181
Cyber squatting

The act of intentionally registering domain names containing trademarks/trade names of prominent companies to later blackmail or demand ransom from those companies is called cyber squatting.


Assume there is a firm Glory Enterprise and it wants to have its web site. It also wants to have the word glory as a part of its domain name because for years it has been recognized in the physical world through this word. However, at the time of registration of its domain name it finds that a person Mr. A who has nothing to do with the business of the firm or the word glory’ has already registered a domain name containing this word as a part of it. Since there cannot be two similar domain names, the firm is forced to request Mr. A to transfer that domain name to it. In response, if Mr. A blackmails or claims ransom from the said firm, he would be said to

have comm    ed cybe     qua     ng
Concurrent iuttse

r s       tti      .

This problem arises when two organizations have apparently legitimate
claim to use the same domain name but cannot do so due to the uniqueness of domain names.

Suppose, there is a company manufacturing electronic goods and another company selling French fries. Under the traditional trade mark law both these companies can have the same trade mark/trade name such as frys’. The problem
arises when both apply for the registration of a domain name containing
the word frys’. Here, both are legitimate claimants of this domain name but due to the element of uniqueness of domain names only
one of them can be assigned the desired domain name.

Question No: 40     (Marks: 5 )

Explain Confidence and Support as two measures of Association? P: 144


There are two terms/measures used in association, that is, support and confidence. Confidence is a measure of how often the relationship holds true e.g, what percentage of time did people who bought milk also bought eggs. Support means what is the percentage of two items occurring together overall.
Mathematically, they can be expressed as follows if we take the example of
eggs and milk:
Confidence = Transactions (eggs + milk) Transactions (eggs or milk or both)
In case no. of transactions involving eggs and milk are 25 and those involving eggs or milk or both are 75
then confidence is 25/75*100=33.3% Support =                       Transactions (eggs + milk) Total no. of transactions
In case no. of transactions involving eggs and milk are 10 and total no. of
transactions in a day is 50 then support is 10/50*100 = 20%
Suppose if confidence is 90% but the support is 5%., then we can gather from this that the two items have very strong affinity or relationship with each other such that when an item is sold the other is sold together, However, the chance of this pair being purchased out of the total no. of transactions is very slim, just 5%.
One can adjust these measures to discover items having corresponding
level of association and accordingly set marketing strategy. So, if I feed the data to the association mining tool and specify the percentage of confidence and support, it will list down the items that have association

corresponding to these percentages. Results of association mining are
shown with the help of double arrows as indicated below: Bread Å----Æ Butter
Computer Å----Æ Furniture

Clothes Å----Æ Shoes

Using the result of association mining, a marketer can take a number of useful steps to set or modify marketing strategy. For example, items that have closeness/affinity with each other can be shelved together to improve customer service. Certain promotional schemes can be introduced in view
of the association mining result etc.
