Abstract: A novel database query and writing engine for rapidly storing, retrieving and modifying large amounts of data on mobile devices is disclosed. The innovative database engine software comprises the creation of a set of files for each table in a database, wherein CRUD (create-retrieve-update-delete) operations are streamlined for mobile or other devices by organizing memory for efficient read and write operations. The set of associated files segregate fixed length and variable length data types for faster seek, read and write operations, and keep track of changes to values and database table schema changes in terms of deletions and insertions of rows and columns. The innovative database engine manages complexities associated with storage and retrieval of large amounts of data, which comprise CRUD operations. In addition, the database engine introduces a dual buffer system to more rapidly process blocks of database memory.

Abstract: A personal information system allowing users to securely collect, store, and transfer personal information is disclosed. The personal information system provides a central location for users to store information, and allows third parties to securely access the information in accordance with user-defined access rules. By providing a central storage area that may be electronically accessed by third parties, the personal information system facilitates the transfer of user information to these third parties. In order to control access to a user's stored personal information, user-defined access rules define the conditions under which third parties may access the stored information. The system also provides user authentication devices that include biometric recognition components and a touch screen display. The user authentication devices may be installed at third party locations to enable a user to authorize the transfer of personal information to third parties.
