**Research Problem and Research Question**
**Abstract**
The rapid integration of artificial intelligence (AI) across sectors like finance, healthcare, and law enforcement has raised significant ethical issues related to fairness and transparency. Machine learning (ML) algorithms frequently depend on extensive datasets that may harbor implicit biases, resulting in inequitable predictions based on race, gender, or socioeconomic status. While numerous fairness-oriented ML strategies have been developed to mitigate bias, these often complicate the decision-making process of the models, making them more challenging to interpret. Conversely, explainable AI (XAI) techniques offer clarity regarding model predictions but do not always resolve fairness-related concerns. This research explores the intersection of fairness and explainability in AI-driven decision-making, specifically examining how techniques such as SHAP (Shapley Additive Explanations) and LIME (Local Interpretable Model-agnostic Explanations) can enhance transparency in fairness-aware models. The study will assess the trade-offs between accuracy, fairness, and interpretability to establish a framework that ensures AI models are ethical, transparent, and applicable in real-world scenarios. The results aim to support the development of responsible AI systems that are both equitable and comprehensible, helping organizations deploy AI solutions that comply with ethical and legal standards.
**Research Problem:**
Artificial intelligence (AI) and machine learning (ML) have become increasingly prevalent in decision-making processes across a variety of sectors. Nevertheless, concerns regarding fairness and transparency have emerged, primarily due to potential biases presented in the data used to train these models. AI systems can occasionally yield discriminatory results that adversely impact specific groups, thereby raising ethical and legal issues. While initiatives aimed at enhancing fairness in machine learning models have been introduced, many of these strategies fail to address the challenge of interpretability. Conversely, explainable AI (XAI) methodologies prioritize model transparency but do not inherently guarantee fairness in their decision-making processes. This research seeks to investigate the effective integration of fairness-aware machine learning models with explainable AI techniques to improve both fairness and interpretability, all while ensuring robust model performance.
**Research Question:**
What methods can be employed to combine fairness-aware machine learning models with explainable AI techniques to enhance transparency and mitigate bias within decision-making systems?
**Introduction:**
Artificial intelligence has become a cornerstone of decision-making in various industries, from healthcare to finance, law enforcement, and beyond. AI-driven systems, powered by machine learning, are used to predict outcomes, assist in decision-making, and automate tasks, offering efficiency and precision. However, as the adoption of these technologies grows, concerns about their ethical implications, specifically regarding fairness and transparency, have become more prominent. The reliance on large datasets for training machine learning models introduces the risk of embedding societal biases into these models, which may lead to discriminatory results.
While efforts have been made to develop fairness-aware machine learning models that mitigate bias, these models often face the challenge of reduced interpretability. On the other hand, explainable AI (XAI) techniques focus on making models more transparent and interpretable, but they do not always address fairness concerns. This research aims to explore the intersection of fairness-aware ML models and explainable AI techniques, seeking ways to combine the two to improve both fairness and interpretability without sacrificing model performance.
Despite growing interest in fairness-aware machine learning (ML) and explainable AI (XAI), research that explores their integration remains limited. Fairness-oriented models often lack interpretability, making it difficult for users to understand the rationale behind decisions. On the other hand, explainability techniques typically improve transparency but fail to ensure fairness in AI decisions.

Forensic Toolkit Testing and Validation Report
## Introduction
This document provides a comprehensive review and validation of forensic tools for the examination of digital evidence. The reasonable procedures, test results and verification processes are detailed in this document.
1.
**Evidence Preservation**
**Tool Used: [FTK Imager v4.7.1]**
This section captures the imaging and preservation of digital evidence, to provide verification of the integrity and authenticity of the original data.
The imaging process included creating a forensic image of the target drive using FTK Imager, specifically a raw (DD) image. Part of the process included calculating the MD5 and SHA-1 hash values of the source drive before and after imaging was complete, and those values were compared to confirm that the drive was not altered during the imaging process. The MD5 and SHA-1 hash values were successfully matched (e.g., MD5: Insert Calculated MD5 Hash Value, SHA-1: [Insert Calculated SHA-1 Hash Value]), which confirms that it is an accurate original bit-for-bit copy of the target drive. Once complete, the image was saved to a secure, write-protected location.
**2.System Profiling**
**Tool Used: [Registry Explorer v1.6.0]**
Description: Analyzing registry hives and validating findings using Access Data Registry Viewer to ensure accurate and complete data related to system configuration.
Description: Registry Explorer was employed to acquire key system configuration data from the target systems registry hives (e.g., SYSTEM, SOFTWARE, NTUSER.DAT) focusing on specific keys of interest such as user account data, installed software and system configurations. The findings from Registry Explorer then underwent verification compared to Access Data Registry Viewer; for instance, user account data, obtained through Registry Explorer was verified against the same user account data through Access Data Registry Viewer to ensure accuracy. Any discrepancies between the obtained data was noted and investigated. The use of successful dual verification of registry entries identified as the Insert Registry Key Path and Insert Registry Value, to validate the summarized findings of both tools.
Description: Analyzing registry hives and verifying results with Access Data Registry Viewer.
**3. File Recovery**
**Tool Used: [PhotoRec v7.2]**
Description: Recovery of deleted files using file carving techniques, with a particular focus on identifying and reconstructing fragmented files.
Description: PhotoRec was used to recover deleted files from unallocated space, and the tool's ability to identify files based on file headers and footers, irrespective-file system metadata, proved useful. Rehabilitation efforts primarily focused on specific file types (e.g., JPEG, DOCX, ZIP) both file identification and reconstruction occurred. These recovered files were then validated through the examination of file contents and through comparison with known good copies. For example, when investigating for recovered JPEG images, we opened all images and visually checked each image for image integrity, while hash value comparisons confirmed file similarity with known good JPEG images. Successful and independent validation of Number JPEG files and Number DOCX files, demonstrates the effectiveness of PhotoRec.
**Description: Recovery of deleted files through file carving techniques.**
****4. Internet-Based Evidence****
****Tool Used: [ Autopsy Web Artifacts]****
**Description: Parsing the Web browser history, cookies and cache files and confirming the findings by inspecting the original SQLite databases.**
****
**Description: Autopsy Web Artifacts allowed for parsing the Web browser artifacts from the target system's browser profiles (Chrome, Firefox etc.). The parsed artifacts (browsing history, download history, and cookie information) were verified by directly opening the pertinent SQLite database files via a SQLite browser for several of the artifacts. An example was shown that certain entries in the history.db file were matched by the parsed history in Autopsy to demonstrate the tool was accurately parsing the data. A successful matched entry would have included "Web History: Site Visited https://insertURL here/ at insertTimestamp here", which would verify the parsing of the tool was accurately retrieving the web history data parsed.**
****Description: We parsed web browser history and verified using SQLite.****
****5. Windows Artifacts****
****Tool Used: [LNK Explorer]****
**Description: Analysis of LNK files, prefetch, thumbnail databases, etc.**
****6. Hash Analysis and Filtering****
****Tool Used: [Autopsy Hash Lookup]****
**Description: The process of calculating and filtering hash values against known hash sets (e.g., NIST NSRL), in order to identify known files and remove non-user related data.**
**Description: Autopsy Hash Lookup was utilized to calculate hash values (MD5, SHA-1) of files from the suspect hard drive. The hash values calculated were then compared against the NIST National Software Reference Library (NSRL) hash set. The files with known hash values were accurately and successfully identified and filtered out from the dataset, allowing an enormous reduction of data that needed to be analyzed manually. For instance, by filtering out known operating system files from the dataset using the NSRL hash set, the amount of time it took to analyze the remaining data was drastically reduced. The filtration of *Number* known files verified the functionality of the hash lookup feature of the tool.**
**Description: Hash values were calculated and filtered.**
****7. File Extension Analysis****
****Tool Used:[TrID File Identifier]****
**Description: TrID analyzes the contents of files to determine the file type regardless of the file extension, allowing the accurate determination of files that have been mislabelled or disguised.**
** TrID is a tool utilized to analyze various files with suspicious file extensions or missing file extensions. The ability of the tool to determine the file type by examining the binary signatures of the file was of utmost importance. For example, a file assigned a text file extension, .txt, was examined using TrID and was verified to be a JPEG image file. This capability of being able to have the file type examined and determined to not be a text file avoids potentially misinterpreting the content of the file. Accurately identifying the File Name to be a JPEG file instead of a .txt file extension speaks to the abilities of TrID.**
**## Conclusion**
**This report details the processes that have been used in testing, validating, and documenting using forensic tools for analysis of digital evidence. Each forensic tool has been thoroughly assessed to ensure quality through thorough and detailed testing, from repeated reliability to the ability to be replicated. Validation is essential to maintain the admissibility of the evidence in a courtroom, and performing validation is a formal process that incorporates more than one forensic method, process, and/or procedure that can repeatably use established industry standards. for each process for the proper standard operating procedures outlined in each description, forensic investigators can get accurate photographic results with a varied range of document examiners and or images achieving consistently a reliable process of each investigation. Continuous learning and adherence to forensic standards after documentation of reports is also necessary to maintain the credibility of forensic analysis.**

Forensic Toolkit Testing and Validation Report
## Introduction
This document provides a comprehensive review and validation of forensic tools for the examination of digital evidence. The reasonable procedures, test results and verification processes are detailed in this document.
1.
**Evidence Preservation**
**Tool Used: [FTK Imager v4.7.1]**
This section captures the imaging and preservation of digital evidence, to provide verification of the integrity and authenticity of the original data.
The imaging process included creating a forensic image of the target drive using FTK Imager, specifically a raw (DD) image. Part of the process included calculating the MD5 and SHA-1 hash values of the source drive before and after imaging was complete, and those values were compared to confirm that the drive was not altered during the imaging process. The MD5 and SHA-1 hash values were successfully matched (e.g., MD5: Insert Calculated MD5 Hash Value, SHA-1: [Insert Calculated SHA-1 Hash Value]), which confirms that it is an accurate original bit-for-bit copy of the target drive. Once complete, the image was saved to a secure, write-protected location.
**2.System Profiling**
**Tool Used: [Registry Explorer v1.6.0]**
Description: Analyzing registry hives and validating findings using Access Data Registry Viewer to ensure accurate and complete data related to system configuration.
Description: Registry Explorer was employed to acquire key system configuration data from the target systems registry hives (e.g., SYSTEM, SOFTWARE, NTUSER.DAT) focusing on specific keys of interest such as user account data, installed software and system configurations. The findings from Registry Explorer then underwent verification compared to Access Data Registry Viewer; for instance, user account data, obtained through Registry Explorer was verified against the same user account data through Access Data Registry Viewer to ensure accuracy. Any discrepancies between the obtained data was noted and investigated. The use of successful dual verification of registry entries identified as the Insert Registry Key Path and Insert Registry Value, to validate the summarized findings of both tools.
Description: Analyzing registry hives and verifying results with Access Data Registry Viewer.
**3. File Recovery**
**Tool Used: [PhotoRec v7.2]**
Description: Recovery of deleted files using file carving techniques, with a particular focus on identifying and reconstructing fragmented files.
Description: PhotoRec was used to recover deleted files from unallocated space, and the tool's ability to identify files based on file headers and footers, irrespective-file system metadata, proved useful. Rehabilitation efforts primarily focused on specific file types (e.g., JPEG, DOCX, ZIP) both file identification and reconstruction occurred. These recovered files were then validated through the examination of file contents and through comparison with known good copies. For example, when investigating for recovered JPEG images, we opened all images and visually checked each image for image integrity, while hash value comparisons confirmed file similarity with known good JPEG images. Successful and independent validation of Number JPEG files and Number DOCX files, demonstrates the effectiveness of PhotoRec.

****4. Internet-Based Evidence****
****Tool Used: [ Autopsy Web Artifacts]****
**Description: Parsing the Web browser history, cookies and cache files and confirming the findings by inspecting the original SQLite databases.**
****
**Description: Autopsy Web Artifacts allowed for parsing the Web browser artifacts from the target system's browser profiles (Chrome, Firefox etc.). The parsed artifacts (browsing history, download history, and cookie information) were verified by directly opening the pertinent SQLite database files via a SQLite browser for several of the artifacts. An example was shown that certain entries in the history.db file were matched by the parsed history in Autopsy to demonstrate the tool was accurately parsing the data. A successful matched entry would have included "Web History: Site Visited https://insertURL here/ at insertTimestamp here", which would verify the parsing of the tool was accurately retrieving the web history data parsed.**
****Description: We parsed web browser history and verified using SQLite.****
****5. Windows Artifacts****
****Tool Used: [LNK Explorer]****
**Description: Analysis of LNK files, prefetch, thumbnail databases, etc.**
****6. Hash Analysis and Filtering****
****Tool Used: [Autopsy Hash Lookup]****
**Description: The process of calculating and filtering hash values against known hash sets (e.g., NIST NSRL), in order to identify known files and remove non-user related data.**
**Description: Autopsy Hash Lookup was utilized to calculate hash values (MD5, SHA-1) of files from the suspect hard drive. The hash values calculated were then compared against the NIST National Software Reference Library (NSRL) hash set. The files with known hash values were accurately and successfully identified and filtered out from the dataset, allowing an enormous reduction of data that needed to be analyzed manually. For instance, by filtering out known operating system files from the dataset using the NSRL hash set, the amount of time it took to analyze the remaining data was drastically reduced. The filtration of *Number* known files verified the functionality of the hash lookup feature of the tool.**
**Description: Hash values were calculated and filtered.**
****7. File Extension Analysis****
****Tool Used:[TrID File Identifier]****
**Description: TrID analyzes the contents of files to determine the file type regardless of the file extension, allowing the accurate determination of files that have been mislabelled or disguised.**
** TrID is a tool utilized to analyze various files with suspicious file extensions or missing file extensions. The ability of the tool to determine the file type by examining the binary signatures of the file was of utmost importance. For example, a file assigned a text file extension, .txt, was examined using TrID and was verified to be a JPEG image file. This capability of being able to have the file type examined and determined to not be a text file avoids potentially misinterpreting the content of the file. Accurately identifying the File Name to be a JPEG file instead of a .txt file extension speaks to the abilities of TrID.**
**## Conclusion**
**This report details the processes that have been used in testing, validating, and documenting using forensic tools for analysis of digital evidence. Each forensic tool has been thoroughly assessed to ensure quality through thorough and detailed testing, from repeated reliability to the ability to be replicated. Validation is essential to maintain the admissibility of the evidence in a courtroom, and performing validation is a formal process that incorporates more than one forensic method, process, and/or procedure that can repeatably use established industry standards. for each process for the proper standard operating procedures outlined in each description, forensic investigators can get accurate photographic results with a varied range of document examiners and or images achieving consistently a reliable process of each investigation. Continuous learning and adherence to forensic standards after documentation of reports is also necessary to maintain the credibility of forensic analysis.**

First, choose and define an audience for your training program. This could be your spouse, your children, fellow soldiers or sailors, your grandparents, your community or church volunteers…a group of whoever you feel would benefit from learning about food safety.
You can either record yourself teaching this lesson to your audience using the classroom video tools or you can prepare a narrated PowerPoint presentation with slides created for each topic. **Be sure you are also submitting a written “script” of what you say in your presentation in the event the audio does not work or is unclear.** _**This script MUST be a separate word document.**_ The script should be divided into the subtopics listed below.
The topics you should teach are listed below. The entire training presentation should be about 3-5 minutes long. Keep in mind the purpose of this activity is to show what you have learned about food safety.
– Title page/introduction – Begin by defining your audience (who are you teaching?)
– Introduction to food safety (basic definitions)
– How a food handler can contaminate food in a home kitchen
– Safe preparation practices. Address general information and make sure to identify one specific hazard related to one food item (such as raw chicken)
– Explain how the food supply is a global, interconnected market and the implications of economic conditions or infrastructure on food safety.
– Define one element of food defense such as tampering, bioterrorism, or food fraud, and provide an example.
– Any general food safety topics you want to include – resources for additional education, educational games, recall notices, etc.
– The last slide does not have to be narrated but it should list all your references. APA format should be used for your reference list. If you are recording yourself rather than slides, be sure to include a reference list (in APA format) on your submitted script.
If you are creating a narrated slide show, 6 topic slides would be sufficient, plus a title/intro slide and a reference slide. The presentation/training session should be between 3 and 5 minutes.
