But the blockchain technology can measure the trust. Reading Mike Gault - the CEO of Guardtime - article in Wired magazine:
A keyless signature provides an alternative method to key-based technologies, and delivers proof and non-repudiation of electronic data using only hash functions for verification. By using hash functions, the technology can prove the time, authenticity, and origin (machine, organization, individual) of the input data.
In addition, keyless signature technology provides mass-scale, non-expiring data validation while eliminating the need for secrets or other forms of trust. Thus, it eliminates the need for complex certificate-based solutions which carry certificate management issues, including expiration and revocation.In practical terms:
This technology helps organizations to validate, verify and self-authenticate their big data. The keyless nature of the technology reduces the security and administrative footprint because it removes the need for cipher keys and passwords, which can be lost or mislaid. For data authentication to be align squarely with data authenticity, taking signatures keyless is key in our new brave big data world.
