Yes, you read it correctly. We are going to hack a fingerprint scanner using glue, How? keep reading.
It's simplest and most efficient technique to hack a fingerprint scanner. Don't worry you do not need to be a computer science Jedi to hack a fingerprint reader.
To hack the fingerprint scanner we are going to make a replica of your fingerprint.
Step 1: Items You Need
For this project, you don't need much of items. You may already have all the items you need.
- Glue - I use fevicol because it's cheaply available in India. You can also use any kind of white wood glue.
- Sugru or Play clay or m-seal - Something to make a mold of your fingerprint. you can also use epoxy putty. I personally prefer m-seal because after drying it hardens and does not bend like sugru.
- Patience - You definitely need patience, because mold and glue can take a complete day to dry.
Before going to next step, let me tell you that all the procedures in this project require perfection.
Step 2: Preparing the Mold
This step is very crucial because the quality of your mold will define the quality of your fingerprint replica. You can prepare your mold using either play clay or m-seal, both works fine. The only difference is that m-seal becomes solid on drying and can be used to make many replicas using the same mold but play clay never dries. In India, m-seal is easily available in any hardware store and is cheap so I prefer that.
If you are using m-seal to prepare your mold then follow this steps.
- Open up the package and you will find two packages inside with different pastes.
- Mix those pastes in equal amount, uniformly.
- Now spread it and make a flat shape out of it. Smoothen the upper surface so that there won't be any cavity or print on the mold.
Using Play Clay:
If you are using clay to prepare your mold then follow this step.
- In clay, you don't have to do anything. Just make a nice flat shape out of it.
- Smoothen the upper surface so that there won't be any cavity or prints on the mold.
While preparing the mold use plastic sheet beneath it so that it won't stick and become easy to use.
Step 3: Applying Fingerprint on the Mold
This step is even more crucial than the previous one. Follow the instructions and Images to apply a good nice print on the mold.
- You must wash your hand so that it removes any dirt from your finger.
- Wet your finger so that it won't stick on the mold and damages the mold.
- Apply gentle pressure on the mold with your finger and remove slowly. You can see the video for reference.
- If the print is not good enough then again smoothen the surface and repeat the process.
- Do this until you get a satisfactory print like shown in the image.
After printing let the mold dry. Do not touch the fingerprint on the mold and follow the next step until the mold dry. It may take up to 6 hours for mold to dry completely. If you are using play clay then you can follow next step immediately because it will never dry.
Step 4: Pouring the GLUE and Making Fingerprint
This step may seem easy but do not underestimate the power of the glue ;-).
- Pour glue evenly and gently without making any bubble. A bubble can completely damage your final print. If you are using thick glue then be more careful about the bubble because it may not come out and ruin your print.
- Don't be a miser in pouring glue. Apply enough glue so that it is on verge of flowing out of the mold, as shown in the image.
- After pouring enough glue, let it dry and do not shake it until it dries.
- It may take up to more than 24 hours for the glue to dry, depending upon the thickness of the glue.
- If you are using white glue then it would become transparent after drying.
- Now when the glue dries completely, gently peel it from the mold. It might be hard because the glue is glue. Also, peel it from all the sides so that it won't stretch or tear. You can see the final print in the image.
Step 5: Testing and Troubleshooting
If you have done every step deliberately then it will definitely work. After peeling the print apply it on any fingerprint scanner to check whether it's working or not. In my case, it worked pretty effectively.
- If it is not working then try changing the position of the print on the scanner.
- It might also be possible that the print is not sitting completely on the scanner so apply a gentle force while testing.
Spread the Love of open source and Happy Making ;-).
