“SAFE BROWSING PROGRAM”

OUR CHILDREN’S PROTECTION AGAINST THE HARMFUL INTERNET CONTENTS

A new software developed by Hungarian experts can bring a breakthrough in the worldwide struggle against harmful contents on the internet, and also against sexual, paedophile harassment.
The filter software developed for the protection of children is already suitable in its present form to filter the harmful words, expressions and pictures loaded on computer which can hurt the development of children, and the next refreshment will be ready in the near future, that protects against photos on the internet, and also against pictures sent by e-mail.
By preparing various language mutations this filter software can protect children in any country of the world.

The Safe Browsing Program

In 2008 — in the spirit of „Safer Internet” program of the European Union — the Safe Browsing Program was produced in Hungary. The aim of the Program is to show the dangers of the internet for our children, and to offer a solution to the problem.

The most important means of the above mentioned is the education: a recommendation is made for children, parents and teachers, how the internet can safely be used during registration, chatting, buying through internet and forums. And another indispensable means is the new technology: 330 Hungarian education institutes taking part in the Program have been using a special, Hungarian developed filter software.

330 schools with 16,000 computers (10 % of the total Hungarian schools’ computers) have already joined to the Program, and another 5,000 households use the software at home.

The Program is being run by the Safe Browsing Society. The Program is supported by the National Police Headquarters, and the Police Headquarters of Budapest; Symantec Hungary and CERT Hungary are the cooperative partners of the Program.

The filter software

The Hungarian developed filter software called Dolphin Knight does not prevent gathering information but hinders the browsing on undesired sites, downloading harmful contents, joys, illegal software, the harassment of paedophile character as well as the spreading of viruses, worms, spy programs.

The filter software contains almost 300 words, expressions (sexual, pornographic, obscene), however parents, teachers can broaden or tighten them optionally. The essence of the operation of the software is that the sites containing these words and expressions do not appear when using the internet. The innovation is that it filters the sexual harassments and violent manifestations: At first it warns children to the danger and then blocks the conversation.

The software has two versions: one for the home users and another one is the public (net) version. With the help of the software the internet using period can be programmed also by calendar and all computer program can be controlled, disabled or allowed.

Novelty: even pictures can be filtered

The development of the new enhanced variety of the Dolphin Knight arrived at its last phase which can offer an enlarged protection compared to the previous one: the system will be able to filter not only texts but also pictures and to control their use.

With the help of the new picture analysing module it will be possible that

The language mutation of the filter software can assist parents and teachers in any country of the world to protect their children from harmful internet contents.

The special technology: the Dolphin Knight filter software

Dolphin Knight is a network and software protecting as well as complex network filtering system. It enables the common supervision of more computers of the same network. The control also covers the programs to be run on computers, internet contents, pictures on the computer and also pictures which should be loaded on internet. The filtering task set by Dolphin Knight can only be altered by the administrator dealing with the operation of the system (parents, teachers, system operator).

When developing DKC special care was given to filtering of internet contents. Serious attention was paid to the disabling of browsing with keywords, which can be fine tuned with a statistical filtering quite easily with a single click. With this method browsing and downloading of illegal internet contents as well as chatting can be controlled.

The solution

Dolphin Knight consists of four modules, a picture analysing, net filtering, a program disabling and an educational module.

Task of the picture analysing module (test phase):

The picture analysing module controls the contents of pictures on the internet and on the computer. After such analysis it does not allow to load up and display any pictures of sex contents and of provoking character on the internet - parents and teachers can make sure if there are sex pictures on the computer used by children and can also be sure that they cannot load up provoking pictures of themselves on the internet.

Task of the educational module:

The system monitors any attempts to start web browsers. It can allow the use of the browsers only if the user (the child) can correctly answer three questions (the number of questions depends on the setting) in connection with the safe use of internet (the topics and questions can be centrally determined). If the user (child) fails to do this, the system directs the user to the site with the correct answers and cannot allow the use of internet – the users (children) can use internet only if by answering the regular questions they learn well what they have to know.

Task of the program disabling module:

With the program disabling module we can determine the programs that can be used by the children – the child can only play with the games allowed by adults.

There is a possibility of limiting the time when children can use the programs – the child can use programs for a certain time, they have no possibility to play and surf all day long.

Task of the net filtering module:

The net filtration can be realised on the basis of IP, URL and keywords.

Filtering on IP basis:

The network limitation on a determined client can be set with IP address, sub-network mask, port and package type. With these settings also the net access within the intranet can be regulated – children cannot reach servers with illegal contents.

Filtration on URL basis:

The quick and simple setting of reachable or disabled URLs is possible – children can see only the web sites allowed for them by parents or teachers.

Internet content disabling on the basis of keywords:

Filtering and disabling internet contents by keywords enables controlling the perfect internet visiting practices.

On the handling surface those words and expressions can be simply given on base of which web contents can be perfectly filtered.

On base of the set keywords in case of identicality the system stops immediately.

There is a possibility to the fine tuning of the disabling with keywords. Fine tuning is made by setting statistical filtering. The essence of statistical filtering is that the safety levels can be set – everybody can set according to its standards the keywords, the contents belonging to same cannot be seen by children, The words in Dolphin Knight are only proposals they can be cancelled or altered.

Chat controlling with keywords:

Chat controlling with keywords enables the automatic disabling of chatting with a unique solution should the chatting take a wrong direction. The solution is based on the keywords and expressions set on the system. The system continuously follows the course of the used chat rooms and if it finds identicality with the set words or expressions it makes an automatic disabling – the solution ensures acceptable protection for children to prevent harassments.

Advantages of the solution:

parents and teachers can make sure if there are sex pictures on the computer used by children and can be sure that they cannot load up provoking pictures of themselves on the internet
