US Patent 11593317 Systems and methods for tamper-resistant activity logging

Systems and methods are provided for monitoring and logging all activity occurring in a system. The logged activity may include keystroke entries input into the system, user and/or application interactions with the system, access restriction conflicts, and the like. The logged activity may be stored in at least two datastores, at least one of which is an immutable, append-only datastore. Storage of the logged activity in the immutable, append-only datastore is performed using hash algorithms. Attempts at manipulating or at hiding malicious or unauthorized activity can be recognized due to all activity being captured in the immutable, append-only datastore.
