Variable encryption scheme for data transfer between medical devices and related data management systems
First Claim
1. A computerized method of transferring encrypted data between and among medical data management systems comprising:
- recognizing data to be transmitted by a device;
determining a level of encryption dependent upon the nature of information to be transmitted by the device;
encrypting the data using a first secure key length for sensitive data;
encrypting the data using a second key length for remaining data; and
transmitting the data over a data communications media.

Abstract
The present invention provides for an encryption apparatus, system, and method in which data from an Implantable Medical Device (IMD) and a data center could be transferred based on a differentiated encryption system. The encryption scheme allows for the differentiation, segregation, and classification of data at required or needed levels of security. Before transfer of the data, either from an IMD or any other part of a support network for the IMDs, the encryption device begins to distinguish the data. The variable data is then classified based on various levels of security having distinct encryption protocols. After classification the data is encrypted based on the data'"'"'s level of security. The data is then transmitted. Upon being received the data is then segregated based on whether the data is encrypted. The encrypted data is then de-encrypted and interpreted.

7. An apparatus for variably encrypting and transferring medical data comprising:
-
a classifier having means for receiving an input of medical data from a medical device or a data management system, assigning a classification based upon what the medical data represents, and outputting the classified medical data to a segregator;
a segregator having means for separating medical data into discrete data payloads according to the classification assigned the medical information by the classifier and outputting the segregated medical data to an encryptor;
an encryptor having means for variably encrypting segregated medical data based upon the level of security assigned to a particular payload of medical data and transmitting the variably encrypted data over a data communications media. - View Dependent Claims (8, 9, 10, 11)
