Fog storage – eliminating the risks of cloud storage
Two Italian IT specialists are proposing a new concept for remote and distributed document storage that can maintain all the benefits of cloud computing but without the security issues involved in putting your sensitive documents on a single remote server.
Instead of storing in the “cloud,” it is better to store the files in the “fog,” propose Rosario Culmone and Maria Concetta De Vivo, of the University of Camerino.
They point out that the technological and regulatory aspects – the legislation of each country – of cloud computing offer opportunities and risks. Having your data hosted on remote servers does away with hardware investment and makes files accessible to remote users more efficiently. However, there are gaps in the security and accessibility of files in the cloud.
That’s why they turned to another meteorological metaphor – fog, or haze – to propose a concept that makes any file entirely immaterial, instead of locating it on a single server. It is this “dilution” of data that lowers the density of the cloud, making it just a haze.
In fog storage, the files are distributed over a public or private network and thus do not have a unique address. In this way, there is not a single server that can target hackers and therefore only legitimate users can access them. Fog computing could bypass security issues and legal issues, putting the files out of the reach of snoops – and the authorities as well.
“Our idea is based on a service that makes information wholly immaterial in the sense that no place on the planet contains the complete information in its entirety in a time span,” writes the duo.
According to what they explain the solution consists of a distributed service – the fog – that uses standard network protocols in an unconventional way, exploiting “virtual buffers” in internet routers to move data packets continuously, without a file reaching the Be recorded in its entirety on a single server.
It’s as if you’re sending a letter with a mail tracking mechanism, but with an incomplete address that simply sends it from one post office to another, then never being delivered.
