A few days ago an article called “Czech children are threatened by the network cyberbullying and pornography” appeared at iDNES. In the article the experts give their opinion on the issue of risky behaviour of children in cyberspace. What struck me most, however, is a quote from NCBI Lenka Eckert, who commented on the issue of watching pornography by children. Unfortunately, the text showed that she does not evaluate this activity negatively, but she sees pornography as "something that is good ... and what can be perceived as education." Although the quote – according to her, is distorted and taken out of context of the whole interview, it incited me to write at least a short comment.
Extortion of children on the Internet has become taboo matter to a certain extent. On the one hand, it is because of the nature of the materials that are used for extortion, on the other hand there is an effort to conceal the individual cases in order to do no harm to victims, conceal a particular problem, hush up the case and try to solve it on its own.
Cyber bullying is in today´s society perceived as a topic associated with pubescent and adolescent young people, only minimum of discussed cases are adults. Although cyber bullying of adults really exists, it is only little discussed and employers try to cover up these cases, in order not to discredit the institution where these cases take place.
In recent years, in connection with a massive expansion of the number of fake profiles on social networks environment, the need to look for methods that allow you to distinguish the fake from the real information has been increasing. One of the methods to identify false photo from the "modified one" or even "fake one" is the use of EXIF metadata specification.
Very dangerous phenomenon, which we have seen in the last few months on Czech and international social networks and within common communication tools based on instant messengers (ICQ, Skype) are fake videos that are projected to chosen victims (children or adults) instead of real stream from a webcam. The risk of misuse of this technology is really high due to the low awareness. You can judge the way the records are believable.
