E-mail is a relatively inexpensive, flexible and quick way of communicating with other people. It is easy to request and exchange genealogical information. E-mail distribution lists are also used for informing you about new versions of Sukujutut.
To ensure the functionality and safety of the network, traffic in the network and the use of the network services are monitored. The maintainer and the service providers trace the activity and use of services per each workstation, but safety and other requirements may require identification of your computer. It is possible to monitor the use of e-mail, record where and how often messages are sent, and it is also possible to read the content of the messages.
Each action in the Internet, browsing the Web pages and participation in discussions leave traces. When you surf in net services or take part in discussion groups, the pages that you visit, items that you view, the frequency of these visits, the time that you use for viewing items, discussion groups that you participate in, and so forth. The traces are registered using the same accuracy in which you give out your information. These traces can be used to make detailed summaries and profiles about your characteristics, interests, likes and so on.
When you submit your name and contact information, like your e-mail address or other information to directories, bulletin boards, and discussion groups, the information usually becomes accessible to everybody. It can be transferred to others or used for other purposes than the one you intended the information. Outsiders can monitor your actions in the net and use the results to create browse profiles about you, send you unsolicited messages, advertisements, ”spam” etc.
Any information submitted to the net can end up in unwanted contexts, for instance, in network services and retail, the information you have received about the other party is not necessarily true. The information may not remain unchanged, it is not always stored or deleted in a proper manner.
It is possible to manipulate a workstation over the network, unknown to the owner of the workstation, to automatically download to the workstation programs, services, files or other items with unknown or uncontrolled functionality or content.
It is difficult to control how the duties of parties processing personal data and the rights granted for registered parties, set by data protection legislation, are implemented in data networks.
Earlier, computer viruses were usually transferred from one computer to another via floppy disks. Nowadays most viruses contaminate computers through e-mail, for example, a Word document sent as an e-mail attachment may contain a virus. These kind of viruses are called macro viruses. Viruses can also spread through surfing in the Web and downloads. You can protect your computer against viruses with virus scanner applications and by updating the search strings of these applications regularly. In case of viruses, it is recommendable to make regular backups on floppy disks.
