US Patent 10277561 Database management system shared ledger support

A business application may provide a secure ledger update while maintaining anonymity and security from unauthorized third parties. One example may include receiving a new entry transaction to save data in a database/ledger. The example may also include receiving a request to add a record stored in a database with a new entry, adding the record by inserting the new entry, and enabling the new entry to be unchangeable from subsequent modification attempts based on an immutable attribute.
