Abstract: Systems and methods for managing keys in a computer memory are described. In some embodiments, location addresses are determined for two key elements. A periodic time interval that is based on a time duration for performing a transaction involving a distance between the key elements is determined. One key element may be stored at a location address and then relocated to another location address after the periodic time interval has passed. In some embodiments, areas the computer memory may remain static during relocation of the key element.

Abstract: Disclosed is technology for storing original work data on a derivative work data blockchain along with code for verifying that derivative work data is derivative of the original work data. The technology involves receiving derivative work data from a submitting entity along with proof data showing that the derivative work is derivative of the original work. If the derivative work data is verified as derivative, then the derivative work data is appended to the derivative work data blockchain.

Abstract: Methods, systems, and media for improving computer security and performance of security are disclosed. In one example, a computer security system comprises a key management monitor, and two key elements comprising a first key element and a second key element. The first key element is stored at a first location address within a computer memory and the second key element is stored at a second location address. The key management monitor is configured to determine or receive a time duration for performing a data dump of contents of the computer memory. In one example, the key management monitor is further configured to control a location of the first key element within the computer memory, wherein the location address of the first key element is changed within a time period that is less than the time duration for performing the data dump of contents of the computer memory.
