WAYS COMPUTER TECHNOLOGY THREATEN OUR PRIVACY

Every time you click on an advertisement or register a software product online, your Information is entered into a database. Computer technology can also threaten privacy through spam. Do you know what spam is? Spam is unsolicited e-mail messages, advertisements or newsgroup postings sent to many recipients at once.

How does computer technology threaten the privacy of our data? It is done through:

• Cookies

• Electronic profile

• Spy ware

Computer technology threatens our privacy through electronic profiling. For example, when we fill out a form such as a magazine subscription, purchasing products or contest entry form on the Internet, this data is kept in the database. It will include age, address, marital status and other personal details.

• are used by some websites to store passwords and track how regularly we visit a website, that’s how we become potential targets for web advertisers
  
• enable web sites to collect information about your online activities and store them for future use, then the collected details will be sold to any company that requests for it.

• can enter computers, sneaking in like a virus.

WHY DO WE NEED PRIVACY?

We need privacy for anonymity. For example, the Internet creates an elaborate trail of data detailing a person surfing on the Web because all information is stored inside cookies. We do not want our trail to be detected.

We also need privacy for confidentiality. For example, online information generated in the course of a business transaction is routinely used for a variety of other purposes without the individual’s knowledge or consent.

We do not want our private lives and habits exposed to third parties.

• Security Management to protect the resources
