US Patent 11487733 Database journal redaction
Article
A database management system stores an entry in a journal. The journal, upon storage of the entry, comprises a leaf node with a hash value based at least in part on the entry, and a hierarchy of interior nodes based at least in part upon the leaf node. In response to a request to delete the entry, the entry is deleted but the hash value is retained. A cryptographic proof of a second entry stored in the journal is based at least in part on the retained hash value.
