Secure analysis system

A system for analyzing a sample, comprising:

• a sample holder comprising:
• a body comprising a unique holder identifier that is uniquely associated with the sample holder;
• a sample compartment formed in the body and configured to contain the sample;
• a cap configured to attach to the body and seal the sample compartment;
• and
• a tamper-evident feature that provides residual physical evidence when the sample compartment has been accessed after the cap is sealed to the body;
• an analyzer configured to retrieve the unique holder identifier from the sample holder and:
• create a measurement of the sample contained in the sample compartment;
• create a data record of the measurement;
• encrypt the data record and a portion of the retrieved unique holder identifier and an authentication parameter to form an encrypted file;
• and
• provide the encrypted file;
• and
• a server communicatively coupled to the analyzer and configured to:
• receive the encrypted file;
• retrieve an encryption key;
• decrypt the encrypted file using the encryption key;
• analyze the measurement;
• and
• provide a result that is based in part on the analysis of the measurement and comprises the portion of the unique holder identifier;
• wherein the combination of the tamper-evident feature and the unique holder identifier of the holder, the inclusion of the portion of the unique holder identifier in the encrypted file, the authentication parameter of the encrypted file, and the inclusion of the portion of the unique holder identifier in the result provide chain-of-custody evidence that the result is associated with the sample contained in the sample holder.
