Windows Data Privacy Scanner Development

@seefattechnologi

Hey As per description, I have excellent experience building Windows scanning apps with multithreaded crawling, local databases, and pattern-based sensitive data detection. C# with .NET/WPF for filesystem access, multithreading, and Office/PDF parsing. Producer-consumer crawler streaming paths in batches, never loading full list into memory. Configurable thread caps and I/O throttling per mode, file hashes skip unchanged files on rescans. Progress saved continuously to SQLite, restart resumes from last saved point, not zero. Hidden/system files read via .NET file APIs with elevated permissions where allowed, denials logged. PDF via PdfPig/iText, DOCX/XLSX via OpenXML SDK, content read directly without needing Office. Tesseract OCR for images and scanned PDFs, commercial-friendly license. Regex plus checksum validation for SIN/card/account numbers, local NER model for names/addresses, fully offline. No, nothing leaves the machine, all storage stays local in SQLite. SHA-256 hashing flags exact duplicate files. Windows ACL inspection via .NET security APIs flags broad-access folders. Encrypted PST/7Z and corrupted files are hardest, flagged clearly. iText, OpenXML SDK (MIT), Tesseract (Apache 2.0), disclosed with licensing. Yes, full source code delivered. Scope is large, want to align on milestones before a fixed number. Happy to share relevant work in the technical conversation. Plesae ping to discuss the requirement timeframe and the budget also. Thanks!!!

Hi, there. "WINDOWS PRIVACY DATA SCANNER" - you need a local-first scanner that can inspect large file sets, detect sensitive data accurately, and resume safely after interruption. I recommend C#/.NET + SQLite with parallel filesystem scanning, bounded workers and persistent scan states for 1M+ files. I can handle PDF/Office extraction, local OCR, regex/checksum detection, hidden files, duplicates, Windows permissions, pause/resume, performance throttling and masked findings. All document processing can remain fully local, with source code, installer, documentation and dependency licences included. Can you share a small representative test dataset so I can confirm the extraction and OCR approach? Looking forward to working with you.

Hi there, I see you're looking for a comprehensive Windows desktop application to scan for sensitive data across various file types. I recommend using C# with .NET for this project, as it will allow efficient file handling and deep filesystem access. I can implement the deep scanning capabilities you've outlined, ensuring that documents remain local with no uploads to external servers. I'll utilize regular expressions and potentially local NLP techniques to minimize false positives while effectively detecting sensitive content. Your requirement for features like paused/resumed scans and a robust reporting system aligns perfectly with my past experience in Windows desktop development. Happy to discuss the details and propose the best approach for your requirements. Regards, Ali

Greetings, I've read through your project requirements, and it’s clear you need a robust Windows desktop application that can thoroughly scan for sensitive information without compromising user privacy. My approach would involve developing a deep file crawler that efficiently examines all specified file types, utilizing advanced techniques like regular expressions and potentially local AI to minimize false positives. With my experience in Windows desktop development, large filesystem scanning, and handling OCR, I can ensure the application performs well even with substantial data sets. I’ll make sure the app can pause and resume scans effectively, while maintaining a user-friendly interface that includes detailed reporting for the findings. I believe this project aligns perfectly with my skills, and I’m excited about the opportunity to work on it. Best regards, Saba Ehsan

Hello, there Your restart test is where most scanners fail: progress must be saved per file, not per folder or at the end. 1. C# on .NET 10 with WPF, SQLite in WAL mode. 2. Streamed enumeration, never listing all files in memory; a bounded queue feeds worker threads; results batch-written to SQLite. 3. Low Impact runs below-normal CPU and low I/O priority with fewer workers. 4. Every file's status is committed as it finishes; resume continues pending files, skipping unchanged ones by size and modified date. 5. Enumeration skips no attributes; hidden and system files included, access denied logged. 6. PdfPig for PDF, Open XML SDK for DOCX/XLSX/PPTX, NPOI for legacy DOC/XLS. 7. Tesseract, fully local. 8. Regex plus checksums (Luhn for SIN and cards), context keywords, custom rules. 9. No file ever leaves the computer. 10. SHA-256, only for same-size files with findings. 11. Windows ACLs read and groups expanded to count users. 12. PST, MSG, RAR and password-protected files are hardest. 13. PdfPig, Tesseract, NPOI: Apache 2.0; Open XML SDK: MIT. All commercial-safe. 14. Full source code, yes. 15. Fixed price and milestones in chat. 16. I build Windows desktop applications in .NET against SQL Server. 1. Windows 10 and 11 only? 2. Network drives needed in phase 1? 3. Selling to accountants and law firms? Thank you. Ankit

@codeandcommand

Regex based sensitive data detection plus OCR for scanned files is the part that trips people up, false positives pile up fast if the patterns aren't tuned. I would use C# with SQLite to log scan results and store match rules separately so you can tune them later without touching code. Can start today, working scanner in 4 days. Budget and timeline here are based on the post alone. Once we go over which file types and data patterns actually matter, the numbers may shift. Want me to send a quick scope doc so we can get moving?

Hi, This privacy scanner requires a reliable first milestone: a Windows-native foundation that can crawl large file systems, preserve scan status, and clearly report inaccessible or unsupported files without exposing document contents. I would recommend C#/.NET with SQLite, a producer-consumer scanning pipeline, incremental metadata and hashing, cancellation-safe checkpoints, and configurable worker throttling. PDF, Office, archive, and image extraction can be isolated behind format-specific services, with local OCR and masked findings designed around offline operation. Similar work includes privacy-sensitive applications involving local data processing, API boundaries, structured findings, and audit-oriented workflows. The architecture would leave clear extension points for detection rules, duplicate analysis, permissions, reporting, and review actions. I propose delivering the crawler, status database, resumable scan engine, and initial installer-ready desktop shell within seven days, with documentation and a practical milestone handoff. Full source ownership and dependency disclosure can be included. Best regards, Bohdan

Hi, I build Windows desktop tools with local SQLite storage, multithreaded crawlers, and offline content extraction. For this scanner I would use C# .NET with a streaming file walker, metadata and hash checks, and resumable scan state so a restart continues instead of restarting. PDF, Office, image OCR, and archive parsing feed regex, checksum, and local NLP detection, with masked previews and exact page, sheet, or line locations. Findings, duplicates, age flags, permission notes, audit logs, and PDF or Excel reports stay on the machine. Full source, installer, docs, and licence list included. Thanks, Nikhil

Hi, Deep content inspection across a large Windows filesystem risks two failures: excessive false positives from naive regex matching and unacceptable system slowdown if file IO and CPU work are not coordinated. I will build a scanner that extracts text per file type, applies deterministic rules plus a small ML classifier for context scoring, and surfaces findings with file path, risk level, and a confidence score so users can triage quickly. I have built Windows desktop tools that traverse NTFS volumes, parse PDF/Office formats, integrate Tesseract OCR for images, and store results in SQLite with per-file status and audit logs. My work includes multithreaded scanners that respect system load, a quarantine module, and exportable reports. I can reference comparable technical implementations on request. I will start by implementing a lightweight file-type dispatcher that extracts text (PDF/Office parsers, plain text, archives, image OCR) and streams content through the detection pipeline while writing incremental state to SQLite. Scans run in worker pools with prioritized IO and CPU queues to meet low impact requirements. - Which folders/drives and default sensitivity profile should I configure for the first prototype? - Do you prefer integrated Tesseract or a paid OCR engine for higher accuracy on scanned documents? Best regards, @melopgabriel

Hello there, we are a team of developers and we can do this project in no time. Thanks Ashish Kumar.

@bojans9

Hello Hope you are doing well I can build this as a C#/.NET Windows desktop application with SQLite, using async/multithreaded incremental scanning, bounded workers and Low/Normal/Maximum resource modes for 1M+ files. Scan checkpoints, metadata/hashes and persistent SQLite state will enable true pause/resume after restart. I’ll enumerate hidden/authorized paths, extract PDF/Office content with local libraries, use Tesseract OCR locally, and combine regex, checksums and configurable rules for detection. Files never leave the machine. SHA-256 will handle duplicates; Windows ACL APIs will inspect permissions. Difficult formats such as encrypted/password-protected PST/MSG/archives will be explicitly reported. I’ll disclose all dependencies/licenses and provide full source. Fixed price: $250 CAD. Timeline: 1weeks across your milestones. Can you confirm whether $250 CAD is the intended fixed budget? Best regards, Bojan

@DeMit19

==============> Hi there, <=============== I can build this as a fully local Windows desktop application using C#/.NET + WPF, SQLite, multithreaded filesystem crawling, Tesseract OCR, local regex/checksum/NER detection, and Windows ACL APIs. Files would remain on-device, with no cloud upload or hidden telemetry. For 1M+ files, I’d use streamed directory enumeration, bounded worker queues, persistent scan checkpoints, metadata/hash caching, configurable CPU/thread limits, and resumable SQLite job state. PDF/Office/image/archive extraction, duplicate hashing, permissions analysis, masked findings, quarantine, reports, audit logs, and installer/source delivery would all be included. Difficult formats such as PST, password-protected archives, and some proprietary document types would be handled separately and clearly reported when unsupported. Timeline : 20 days Question: Should the first release include PST/MSG/7Z/RAR support, or can those be added after the core PDF/Office/image/ZIP scanner is accepted? Best regards, Dejan

Hi, there. "WINDOWS PRIVACY DATA SCANNER" - you need a local-first scanner that can inspect large file sets, detect sensitive data, and resume safely after interruption. I recommend C#/.NET + SQLite with parallel file scanning, bounded workers and persistent scan states for 1M+ files.

Looking forward to working with you.

@carlosd178

Hello, 1. C#/.NET + WPF/WinUI, SQLite. 2. Stream directory enumeration; process files in bounded batches with indexed DB records. 3. Configurable worker count, I/O throttling and Low/Normal/Maximum modes. 4. Persist scan queue/status continuously in SQLite; resume unfinished items and skip unchanged files using metadata/hash. 5. Enumerate hidden/system files through Windows APIs where permissions allow. 6. PDF/Office parsers with page/sheet/cell/paragraph location tracking. 7. Local Tesseract OCR; no cloud OCR. 8. Regex + checksum validation + configurable rules, with optional local NER for contextual detection. 9. Files remain local by default. 10. SHA-256 hashes for exact duplicates. 11. Windows ACLs via .NET security APIs. 12. PST, password-protected archives, proprietary/encrypted formats require extra handling. 13. I’ll provide a complete dependency/licence inventory; only commercially compatible libraries will be selected. 14. Full source, schema, build instructions and documentation included. 15. Given the full scope, CAD $250 is not realistic for a production-ready implementation. I’d propose a paid first milestone/prototype, then a fixed final quote after validating extraction and performance requirements. 16. I can demonstrate the architecture and relevant C#/.NET, local-data and document-processing work during discussion. I’d follow your proposed milestones and preserve strict “not scanned + reason” reporting. Best regards, Carlos.

Duplicates: SHA-256/file hashes, calculated efficiently with metadata/size filtering before hashing where appropriate. Windows permissions: inspect ACLs using Windows security APIs and report potentially broad access as an exposure indicator, not as a legal conclusion. Difficult formats: PST/MSG, encrypted archives, proprietary formats and heavily corrupted documents need separate handling and will be reported explicitly when they cannot be inspected. Libraries/licensing: I’ll provide a complete dependency/SBOM-style list with versions and commercial/OSS licence information before final delivery. Source: full source code, build instructions, schema and deployment/installer configuration are included. Delivery plan File crawler + SQLite scan-state engine PDF/Office/image/archive extraction Detection engine + custom rules Findings dashboard + evidence/location mapping Pause/resume + performance controls Duplicate/age/permission analysis Review workflow + reports + audit log Installer, security hardening and acceptance testing I’d specifically test the restart scenario and your blind test dataset before calling the application complete. Estimated delivery: 10–12 weeks
