Latest Patents

Jaeheung Lee holds a patent for a "Flash memory device having secure file deletion function and method for securely deleting flash file." This invention discloses a flash memory device that features a secure flash file deletion function. The method involves storing data and object headers separately in data blocks and header blocks. The data is encrypted, and a decryption key is included in the object header stored in the header block. When a flash file is deleted, the object header is removed by searching the header block where the decryption key is located. A binary tree structure is utilized to facilitate this search, with a terminal node indicating the least significant bit of a file ID. This innovation is particularly applicable to embedded systems using NAND flash memory as a storage medium.
