Title: Innovations of Stephen Peter Legg
Introduction
Stephen Peter Legg is a notable inventor based in Southampton, GB. He has made significant contributions to the field of data storage technology, holding a total of 15 patents. His work focuses on enhancing data security and storage efficiency, which are critical in today's digital landscape.
Latest Patents
One of Legg's latest patents is titled "Method and apparatus for virtually erasing data from WORM storage devices." This invention discloses a storage device capable of selectively rendering certain data irretrievable. The device includes a Write Once Read Many (WORM) storage medium, a key generator, an encrypted write component, an erasable storage medium, and a key deleter. The WORM storage medium is designed to store data that is unerasable and unrewritable. The key generator provides a generated key that can be stored in the erasable storage medium. The encrypted write component writes sensitive data encrypted with the generated key to the WORM storage medium. When a request to delete the sensitive data is made, the key deleter removes the generated key from the erasable storage medium.
Another significant patent by Legg is "Preemptive write-inhibition for thin provisioning storage subsystem." This invention processes write requests from host computers in relation to a thin provisioning storage subsystem. It involves determining whether a first virtual disk assigned to a host computer requires additional physical storage locations for data associated with a write request. If additional storage is needed, the system assesses the quantity of free space remaining unallocated within the physical storage locations. If this quantity meets a policy threshold associated with a second virtual disk, the second virtual disk is write-inhibited, ensuring efficient storage management.
