Many people like to publish information on the Internet

Way

Even frequent deletion of text and pictures posted online is still hard to erase, as search engines automatically "comb" the web and write down all the information posted above.

Michael, an expert on information security and cryptography at Saarland University in Germany, said that "you need to prevent data from being automatically stored" if you want to completely erase the information you publish.

According to Baker's Assumption, the German news agency reported 26th, as long as the computer installed a plug-in, on the Internet to publish information can be set a "expiration date."

"A key and expiration date will be stored on the server ... Once the expiration date, the key disappears forever, and the data is never seen again, "he explained.

Prevention

Setting a "failure period" for online information can reassure parents, as many minors lack a sense of privacy, Baker said.

Baker's idea was good, but the effects were questioned.

"The expiration period" does not guarantee that the data will be used by others, and third parties can "copy, store and edit (photos) and put them back online," said Katya Knirim, director of the Jugenschutz.net website.

Knirim and another youth protection worker, Walter Lerichy, urged people to publish too much privacy information on the Internet as much as possible.

Even if the reading information is limited to a circle of friends, "some friends are not always friends," Lerichy said. "No computer software can be foolproof (privacy protection)." ”

Worry

When people publish information on the Internet, they may not be surprised by how the information will affect them in the future. Stefan, a 26-year-old athlete, realized the impact.

Stefan was a good-looking guy who studied in Spain for a semester and had good grades. Handsome he has been hit by a wall when he is looking for a job. Stefan finally realized that trouble was in the picture he had uploaded to the web.

His name makes it easy to search for photos of the parties he had taken during his study in Madrid and for comments made online. Those pictures give the impression that he spends more time in Madrid, and those words are vulgar and distasteful.

Thomas Roubert is head of a job counseling agency in Germany. If a human resource manager sees a male job seeker's bohemian photo with the opposite sex, he says, it may be feared that hiring such a person would upset the other staff.
