Abstract

In one aspect, the invention encompasses a method of storing and retrieving a communication. A communication is stored in a database, and comprises a plurality of sub-components. The communication is stored utilizing software configured to save a plurality of machine-readable identifier codes associated with the communication in the database. The identifier codes identify different sub-components of the communication. Some of the sub-components of the communication are printed together with at least some of the identifier codes as a document. The document does not include all of the sub-components of the communication. The identifier codes are read from the document with a machine configured to extract the identifier codes from the machine-readable format. The identifier codes extracted by the machine are provided to a processor in data communication with the database. The processor is configured to identify all sub-components of the communication. The processor retrieves at least one sub-component from the database that was not printed on the document, and sends the at least one sub-component to an output device.

Claims

1. A method of storing and retrieving a document with different levels of document security provided for different portions of the document, comprising:

creating a data set corresponding to a document and storing the data set in a database, the document comprising a plurality of portions, the storing utilizing software configured to save a plurality of machine-readable identifier codes associated with the data set in the database;

the identifier codes identifying the different portions of the document;

the database being accessible to a plurality of users;

some portions of the document being defined as secure portions and other portions being defined as non-secure portions;

some users having authorization to access non-secure portions of the document and not having authorization to access secure portions of the document;

the users being assigned access codes which identify if the users have clearance to access secure portions of the document;

printing the non-secure portions of the document together with at least some of the identifier codes on a substrate;

providing the identifier codes to a processor in data-communication with the database, the processor being configured to retrieve both the secure and the non-secure portions of the document and to send the retrieved portions of the document to an output device;

the processor being further configured to recognize if an access code provides clearance to secure portions of the document;

requiring a user to input its individual access code to the processor before secure portions of the document are sent to the output device; and

the processor sending secure portions of the document to the output device only if the inputted individual access code indicates that the user has clearance to obtain the secure portions.

2. The method of claim 1 wherein the user is required to input its individual access code before any portions of the document are sent to the output device.

3. The method of claim 1 wherein the user inputs the access code through keyboard or voice input.

4. The method of claim 1 wherein the access code comprises physical information about the user, and wherein the processor is in data communication with a sensor configured to sense the physical information.

5. The method of claim 1 wherein the identifier codes are printed on the non-secure portions of the document in machine-readable format, wherein the identifier codes are read from the substrate with a machine configured to extract the identifier codes from the machine-readable format, and wherein the identifier codes are provided from the machine to the processor.

6. The method of claim 1 wherein the identifier codes are printed on the non-secure portions of the document in user-readable format, wherein the identifier codes are read from the substrate by a user, and wherein the identifier codes are input to the processor by the user.
