    (a) In General.--Not later than 1 year after the date of enactment 
of this Act, the Director of the National Institute of Standards and 
Technology shall establish a program to provide for creation and 
maintenance of standards for the development and use of computational 
forensic software, to be known as the Computational Forensic Algorithm 
Standards, consistent with the following:
            (1) Standards shall include an assessment for the potential 
        for disparate impact, on the basis of race, ethnicity, 
        socioeconomic status, gender, and other demographic features, 
        in the development and use of the computational forensic 
        software.
            (2) Standards shall address--
                    (A)(i) the underlying scientific principles and 
                methods implemented in computational forensic software; 
                and
                    (ii) if, in the case of a particular method, there 
                are insufficient studies supporting its use, what 
                studies the Director has conducted to do so, and the 
                results of such studies;
                    (B) requirements for testing the software including 
                the conditions under which it needs to be tested, types 
                of testing data to be used, testing environments, 
                testing methodologies, and system performance 
                statistics required to be reported including--
                            (i) accuracy, including false positive and 
                        false negative error rates;
                            (ii) precision;
                            (iii) reproducibility;
                            (iv) robustness; and
                            (v) sensitivity;
                    (C) requirements for publicly available 
                documentation by developers of computational forensic 
                software of the purpose and function of the software, 
                the development process, including source and 
                description of training data, and internal testing 
                methodology and results, including source and 
                description of testing data;
                    (D) requirements for laboratories and any other 
                entities using computational forensic software to 
                validate it for use, including to specify the 
                conditions under which the lab has validated it for 
                their use, requirements for what information needs to 
                be included in a public report on the lab or other 
                entity's validation, and requirements for internal 
                validation updates when there are material changes to 
                the software; and
                    (E) requirements for reports provided to defendants 
                by prosecution produced documenting the use and results 
                of computational forensic software in individual cases.
            (3) Standards shall be issued as a rulemaking under section 
        553 of title 5, United States Code.
            (4) The Director shall consult with outside experts in 
        forensic science, bioethics, algorithmic discrimination, data 
        privacy, racial justice, criminal justice reform, exonerations, 
        and other relevant areas of expertise identified through public 
        input.
    (b) Protection of Trade Secrets.--The Federal Rules of Evidence are 
amended by adding at the end of article V the following:

``RULE 503. PROTECTION OF TRADE SECRETS IN A CRIMINAL PROCEEDING.

    ``In any criminal case, trade secrets protections do not apply when 
defendants would otherwise be entitled to obtain evidence.''.
    (c) Requirements for Federal Use of Forensic Algorithms.--Any 
Federal law enforcement agency or crime laboratory providing services 
to a Federal agency using computational forensic software may use only 
software that has been tested under the National Institute of Standards 
and Technology's Computational Forensic Algorithm Testing Program and 
shall conduct an internal validation according to the requirements 
outlined in the Computational Forensic Algorithm Standards and make the 
results publicly available. The internal validation shall be updated 
when there is a material change in the software that triggers a 
retesting by the Computational Forensic Algorithm Testing Program.
    (d) Requirements for Testing.--The Director of the National 
Institute of Standards and Technology shall establish a Computational 
Forensic Algorithm Testing Program, whose activities include the 
following:
            (1) Testing individual software programs using the testing 
        requirements established in the Computational Forensic 
        Algorithm Standards.
            (2) Using realistic sample testing data similar to what 
        would be used by law enforcement in criminal investigations in 
        performing such testing, including incomplete and contaminated 
        samples.
            (3) Using testing data that represents diversity of racial, 
        ethnic, and gender identities and intersections of these 
        identities in performing such testing.
            (4) Using testing data that tests the limits of the 
        software and demonstrates the boundaries of reliability 
        described in the performance measures defined in the 
        Computational Forensic Algorithm Standards in performing such 
        testing.
            (5) Publishing the results of testing the software online 
        including results under conditions specified in the standards 
        and across diversity of racial, ethnic, and gender identities 
        and intersections of these identities in a publicly available 
        format.
    (e) Testing Frequency.--Retesting shall be conducted when a 
material change is made to the software that impacts its performance 
and may affect its outputs. The Director shall establish requirements 
for determining whether changes are material or nonmaterial.
    (f) Discovery in Criminal Cases.--Rule 16 of the Federal Rules of 
Criminal Procedure is amended--
            (1) in subdivision (a)(1), by adding at the end the 
        following:
