System and method for managing historical information on an object on an electronic tag
First Claim
1. A distributed database system for tracking historical information about an entity, the distributed database system comprising:
- a processing system that includes data rules for processing received data;
a data tag associated with the entity, the data tag storing historical data regarding the entity, the historical data stored on the data tag as variable field length encoded data in a plurality of data fields; and
a communication system for transferring the variable field length encoded data between the processing system and the data tag, the processing system receiving the variable field length encoded data from the data tag and decoding the data to retrieve the historical data encoded on the data tag.

Abstract
A distributed database system and associated methods maintain historical data regarding an entity, such as a person or an object, in a tag or other object in association with the entity. The data proper is maintained with the entity and the data rules used to interpret the data proper are maintained at a separate location. The data proper maintained with the entity is stored in a manner to reduce the amount of memory space required. The data proper maintained with the entity is effectively encrypted from parties that do not have access to the data rules. The data proper may be converted to a fixed form, such as a bar code label, and attached to the entity to permit historical information to be ascertained at a later time.

8. A method of tracking historical information about an entity, the method comprising:
-
storing the historical information as variable field length encoded data on a data tag associated with the entity;
reading the variable field length encoded data and decoding the variable field length encoded data to reproduce the historical data;
updating the historical data to include additional information about the entity; and
storing the updated historical data as variable field length encoded data on the data tag associated with the entity. - View Dependent Claims (9, 10, 11, 12, 13)
