Method For Detection Of Tampering With System Password Files

Although password files are a necessity for securing computer systems, a password file alone is vulnerable to manipulation by an attacker. This invention detects tampering with the password file by signing the password file utilizing a public/private key system. This adds an additional layer of security that ensures that password hashes cannot simply be replaced when the system is offline.

What we are trying to do?

We are attempting to mobilize the creativity and innovative capacities of the Linux and broader open source community to codify the universe of preexisting inventions in defensive publications that upon publication in the IP.COM database will immediately serve as effective prior art that prevents anyone from having a patent issued that claims inventions that have already been document in a defensive publication. In addition to creating a vehicle to utilize this highly effective form of IP rights management for known inventions, it is hoped that the community will use defensive publications as a means of codifying future inventions should the inventors prefer not to make their invention the subject of a patent disclosure and application.
