IBM awarded patent for blockchain-based security system
IBM has won a new blockchain-based patent that could stop potential security breaches within computer networks and secure critical company data.
The patent was first filed in September 2017 for “a method for determining security breaches within a network” and awarded on Tuesday by the US Patent and Trademark Office (USPTO).
It outlines how a network of monitors in a chain configuration would link with a primary monitor and backup monitors. The plurality of monitors can write to the shared permanent log once a consensus is reached using blockchain technology.
IBM said securing a data log using monitor security protocols may be accomplished with different levels of security, ranging from low security to high security, and have various combinations of hardware and software configurations. Low security may allow open access to the event logs while high security may significantly restrict access to the event logs.
However, it had identified that protecting a monitored system from hackers gaining access to alter the event logs may require a new type of security configuration.
With the new technology, potential intrusions can be detected as events are logged to a network with multiple backups.
The patent states: “Having synchronized monitors set up in a blockchain configuration ensures consensus among the monitors. Since one monitor alone cannot alter the event log in the past or cannot fake the event log in the future, if one monitor is hacked, then there may be no consensus among the synchronized monitors and the event may not get written into the log.”
The aim, according to IBM, is to “create a less vulnerable network”.
