Abstract
Abstract A method and apparatus are provided for data management authentication in a clinical analyzer. The clinical analyzer includes a sensor for receiving a user sample to be measured and a processor for performing a predefined test sequence for measuring a predefined parameter value. A memory is coupled to the processor for storing predefined parameter data values. An authentication password is associated with each data transmission by the clinical analyzer and read by an associated computer system to validate each data transmission. The authentication password is generated by the clinical analyzer utilizing predetermined information in each data transfer.

receiving means for performing a predefined test
sequence for measuring a predefined parameter value; memory means coupled to said processor means for
storing said predefined parameter data values; communications means coupled to said processor
means for transferring data to a computer system; each
said data transfer including an authentication password
and said predefined parameter data values; said
authentication password used by said computer system to
validate each said data transfer.
Claim 2
Dependent Claim
25 words
A clinical analyzer as recited in claim 1
wherein said authentication password is generated by
said processor means utilizing predetermined information
in each data transfer.
Claim 3
Dependent Claim
21 words
A clinical analyzer as recited in claim 2
wherein said predetermined information in each data
transfer includes a time stamp value.
Claim 4
Dependent Claim
24 words
A clinical analyzer as recited in claim 3
wherein said time stamp value includes a current date
and time value for said data transfer.
Claim 5
Dependent Claim
23 words
A clinical analyzer as recited in claim 4
wherein said predetermined information in each data
transfer includes a fourteen day average glucose value.
Claim 6
Dependent Claim
42 words
A clinical analyzer as recited in claim 1
wherein each said data transfer includes said
authentication password in a message header and said
predefined parameter data values are included in a
plurality of results records, said results records
following said message header.
Claim 7
Dependent Claim
22 words
A clinical analyzer as recited in claim 6
wherein said message header includes a current time
stamp value for said data transfer.
Claim 8
Dependent Claim
23 words
A clinical analyzer as recited in claim 7
wherein one of said plurality of results records
includes a fourteen day average glucose value.
Claim 9
Dependent Claim
44 words
A clinical analyzer as recited in claim 8
wherein said wherein said authentication password
generated by said processor means is read and compared
with a calculated value by said computer system
utilizing said current time stamp value and said
fourteen day average glucose value.
Claim 10
Independent Claim
96 words
A method for validating each data transfer
from a clinical analyzer to a computer system comprising
the steps of: providing the clinical analyzer with a sensor for
receiving a user sample and a processor for performing a
predefined test sequence for measuring a predefined
parameter value; storing said predefined parameter values, and transferring stored data to a computer system; each
said data transfer including the step of calculating an
authentication password, and transferring said
authentication password and said predefined parameter
data values; said authentication password used by said
computer system to validate each said data transfer.
