Abstract: A database management system receives a request to perform a transaction. The database management system commits the transaction, and in response to committing the transaction, generates a cryptographic hash based on an attribute of the transaction. The cryptographic hash is stored in a leaf-region of a hash tree. In response to a request to verify the transaction, signatures are retrieved from the tree based on a traversal of the tree to locate the node corresponding to the transaction. The retrieved signatures are used to verify the transaction.

Abstract: A flexible tagging and searching system can be configured to associate tags with the input data to enable a search of the input data. The flexible tagging and searching system can receive user data and determine an identifier associated with the user data. The system can compare the identifier with other identifiers to determine that the identifier is unique. After determining that the identifier is unique, the system can associate a critical tag with the user data and store the critical tag in a database. Then the system can associate a non-critical tag with the user data. In some instances, the system can return query results such as a set of tag data and/or a set of data items.
