Securing Log Files through Blockchain Technology.

Development of secure methods for storing log files is of tremendous importance for cyber security. One of the first actions by a hacker upon penetrating a machine is editing the log files to remove evidence of their presence. We propose to improve the security of these log files through a blockchain based solution. We show how our solution can be used to help organizations to mutually protect their sensitive log data even if some of them are compromised. Our solution allows data confidentiality between the collaborative parties.
