10 of expertise identified through public input. 

11 (b) PROTECTION OF TRADE SECRETS.— 

12 (1) There shall be no trade secret evidentiary 

13 privilege to withhold relevant evidence in criminal 

14 proceedings in the United States courts. 

15 (2) Nothing in this section may be construed to 

16 alter the standard operation of the Federal Rules of 

17 Criminal Procedure, or the Federal Rules of Evi18 dence, as such rules would function in the absence 

19 of an evidentiary privilege. 

20 (c) REQUIREMENTS FOR FEDERAL USE OF FOREN21 SIC ALGORITHMS.—Any Federal law enforcement agency 

22 or crime laboratory providing services to a Federal law 

23 enforcement agency using computational forensic software

3 outlined in the Computational Forensic Algorithm Testing 

4 Standards and make the results publicly available. The in5 ternal validation shall be updated when there is a material 

6 change in the software that triggers a retesting by the 

7 Computational Forensic Algorithm Testing Program. 

8 (d) TESTING PROGRAM.—The Director of the Na9 tional Institute of Standards and Technology shall estab10 lish a Computational Forensic Algorithm Testing Pro11 gram, whose activities include the following: 

12 (1) Testing individual software programs using 

13 the testing requirements established in the Computa14 tional Forensic Algorithm Testing Standards. 

15 (2) Using realistic sample testing data similar 

16 to what would be used by law enforcement in crimi17 nal investigations in performing such testing, includ18 ing incomplete and contaminated samples. 

19 (3) Using testing data that represents diversity 

20 of racial, ethnic, and gender identities and intersec21 tions of these identities in performing such testing.

9 from machine learning, statistics, or other data proc10 essing or artificial intelligence techniques, to process, 

11 analyze, or interpret evidence. 

12 (2) MATERIAL CHANGE.—The term ‘‘material 

13 change’’ means an update to computational forensic 

14 software that may affect the performance measures 

15 defined in the Computational Forensic Algorithm 

16 Testing Standards or the use or output of the soft17 ware.
