Abstract: A system and method for communicating secure, privatized data stored on a first user device with a second user device requesting access thereto includes initiating a timed access gate for receiving verification of authenticating credentials from the second user device, after the first user credentials associated with the first user device are verified. If the second user device is verified within the predetermined period of time, an authentication handshake between the first user device and the second user device is completed. On completion of the handshake, a communication channel is opened for transmitting the first user's privatized data between the first user device and the second user device.

Abstract: A system and method for providing, managing, and accessing a multi-user secure portable database using secure memory cards is provided. The database has a secure portion for storing security keys and a non-secure portion for encrypted data files. Access to the encrypted data files is controlled by assigning access rights through an access control matrix to each encrypted data file according to a hierarchical structure of users. A user requesting access is identified in the hierarchy, associated with a key for allowing the requested access, and the requested access allowed to a file in accordance with the rights allocated through the access control matrix. A patient can selectively grant access to encrypted medical records on his card to a physician. Authentication of the owner/patient is preferably required. Other records required by emergency medical personnel are readable from the same card without requiring permission from the patient.
