A Justice Ministry subcommittee has issued a report on cyber commerce recommending the creation of an electronic certification system to secure electronic transactions, ministry officials said Thursday.

The subcommittee of scholars, lawyers and officials from the financial and communications industries has been discussing since June ways to prevent computer crimes in electronic commerce. The report was released at the end of March.

The officials said domestic and international cyber commerce has increased tremendously, but at times has been abused due to the difficulty of identifying users. Unlike with paper transactions, electronic data can be easily intercepted and falsified by unauthorized parties, they said.

The report calls for the introduction of an electronic certification system based on the existing "tokibo," or corporate registration records. It also calls for the use of notaries public in the electronic system because they are certified by the government and are highly credible.
