After the appearance in latest generation smartphones and mobiles, there are many who seek to insert a fingerprint reader to their projects or gadgets. This is very useful for projects or uses that need a high level of security. That is why the maker Joshua J. Engelsma decided to use all the free hardware that existed to improve and enhance the fingerprint reader.
Thus, Joshua was trying to create a fingerprint reader that was proof against forgeries and false detections, but also that users could create a basic and totally free fingerprint reader for Free Hardware projects.
This is how the RaspiReader project, a project that creates a complete and secure fingerprint reader with several cameras, a glass, LED lights and a Raspberry Pi 3.
The latter is used not only to store fingerprints but also to process the fingerprints that they can use and be able to know if it really is an original fingerprint or just a fake. Therefore, when Raspberry Pi receives the image of the fingerprint, the program looks for errors or possible folds that exist in the image and that indicate that it is a fake.
Joshua J. Engelsma has used the RaspiReader project to your obligations to the University of Michigan but fortunately the project is publicly available, so we can create a fingerprint reader like RaspiReader, not only in terms of Hardware but also in terms of Software, since in the github repository We can find all the libraries and programs written in python that automate the entire RaspiReader process.
The most interesting thing about this project is that RaspiReader is fully compatible with other Free Hardware projects, that is, we can use it as security to open doors, to open accesses such as internet access or simply to start any vehicle that we build. And you Do you dare to build your RaspiReader?
