Russian 'codeheads' develop ‘unbreakable’ code

Russian programmers have developed a way to sign digital documents using electronic signatures that can be used to prevent forgery. A unique digital code can be used to sign documents, for example, received through the Internet or in courts for legal docu

Each digital signature is developed privately for every costumer.

The recipient can check its authenticity using a programme that decodes the document.   

The developers say breaking the code could take up to 300 years, which prevents forgery.
