More than two decades after the release of primary versions of the web browser, different kinds of web browsing software with various capabilities have become available to users. The fast loading of pages, customizability, and most importantly, proper security, have all led to the success of different companies such as Netscape, Microsoft and Google. Now, after years of dramatic changes and evolving browser versions, IBM has come up with a unique idea for the new generation of browsers. In its new patent, the company introduced a blockchain-based web browser that can guarantee users' data security and privacy.
The new IBM patent which was filed in the US Patent and Trademark Office in March 2017 is granted recently with patent number US10375105. IBM's innovative browser is supported by a peer-to-peer network enabling secure data storage. This information storage system is based on blockchain technology, and the information collected is completely tailored to user type: web browser settings on a work PC are quite different from those for a personal browser. This technique includes wide range of data such as visited websites, bookmarks and even installed plugins. According to IBM, the blockchain-based browser provides information storage in a way that fully protects privacy. With this new blockchain based browser information control is completely done by the user. One of the proposed applications for this system is to counter browser attacks, with providing a backup of all information (peer-to-peer is a term associated with computer networks in which each computer can act as a server for others. This feature enables shared access to information without the need for a central server).
Few years after the emergence of blockchain technology, a wide range of different applications have been developed and commercialized by various companies, including financial services and money exchange, social networking, digital management of additive manufacturing process, and even patent tracking and valuation. It is notable that IBM's blockchain-based browser was not the first case with this subject. Previously, in June 2019, a similar idea provided by the Norwegian company Opera who launched the iOS Opera Touch Browser version with a built-in cryptocurrency wallet. It is built for Web 3.0 and can be integrated with applications such as ERC-20.
