I built a Windows security suite that photographs anyone who guesses your password wrong — ATLOCK v4

Description and use

ATLOCK v4 is a Windows security suite that protects files via NTFS ACLs and captures photos and videos of intruders after failed password attempts, storing evidence in a gallery folder.

Problem

Windows login screens can be brute‑forced and users have no visibility into who is attempting to access protected files.

Outcome

ATLOCK v4 provides system‑level file protection, real‑time intrusion evidence capture, and secure credential handling, improving user awareness and deterrence of unauthorized access.

Workflow

• 1. User protects a file with ATLOCK File Guard, which removes NTFS read permissions for non‑authorized users.
• 2. When an intruder attempts to open the file, ATLOCK intercepts the failed password entry.
• 3. On the first wrong attempt, ATLOCK silently captures a photo via the webcam.
• 4. On the third or fourth wrong attempt, ATLOCK records a 10‑second video and sounds an audible alarm.
• 5. All captured media is saved to Pictures/ATLOCK Security and Videos/ATLOCK Security.
• 6. The user can review the evidence and adjust capture settings in ATLOCK’s settings panel.

Evidence

Three wrong password attempts on a guarded file, and ATLOCK has already taken their photo, recorded 10 seconds of video, sounded an alarm, and dropped the evidence straight into your gallery.

Source

File Guard drops down to Windows NTFS ACL permissions and actually strips read access at the filesystem level.
