## Abstract

Various exemplary embodiments relate to an anonymous database system. The system includes a plurality of biometric nodes in communication with one another. Each of the plurality of biometric nodes includes a biometric input that receives biometric data from a user. The system also includes at least one central database in communication with the plurality of biometric nodes; and a plurality of institution databases in communication with the plurality of biometric nodes. A first node of the plurality of biometric nodes is configured to receive a message from a second node of the plurality of biometric nodes, the message requesting authorization of data access by the second node. Various embodiments relate to a method for performing an action requiring multiple levels of authentication using an anonymous database system.

## Claims

### Claim 1

A central biometric node requiring multiple levels of authentication, wherein the central biometric node is configured to:
receive a request to perform an action from a first user operating a first biometric node;
receive biometric data from the first user;
determine, using the biometric data, whether additional authorization is required to allow the requested action to proceed;
query a database with the biometric data to obtain a biometric random key;
send the biometric random key to the database to retrieve security clearance information for the requested action;
retrieve the security clearance information for the requested action based on the biometric random key;
determine, based upon the retrieved security clearance information, whether to request additional authorization;
after determining that additional authorization is required, send a request for additional authorization to a second biometric node;
receive authorization data at the second biometric node; and
allow the requested action to proceed.

### Claim 2 (depends on 1)

The central biometric node according to claim 1, where the requested action is selected from the group consisting of aggregating data associated with the first user, gaining access to a restricted area, and transferring funds.

### Claim 3 (depends on 1)

The central biometric node according to claim 1, further configured to:
access the security clearance information to identify the second biometric node that will receive the request for additional authorization.

### Claim 4 (depends on 1)

The central biometric node according to claim 1, wherein the authorization data is second biometric data obtained from a second user.

### Claim 5 (depends on 1)

The central biometric node according to claim 1, wherein the authorization data is received from a card inserted into a card slot of the second biometric node.

### Claim 6 (depends on 1)

The central biometric node of claim 1, wherein the authorization data comprises second biometric data and central biometric node is further configured to:
query the database with the second biometric data to obtain a second biometric random key, the second biometric random key generated during a first enrollment process independently of the second biometric data and stored in association with the second biometric data; and
determine whether the second biometric random key matches the security clearance information.

### Claim 7 (depends on 6)

The central biometric node of claim 6, wherein the security clearance information comprises a biometric random key of a second user required to provide authorization.

### Claim 8 (depends on 6)

The central biometric node of claim 6, wherein the authorized personnel is a healthcare personnel and the information is a medical record.
