Develop embedded os and java platform

MAKE SURE YOU READ ALL THE DESCRIPTION BEFORE CONTACTING US. The mission that we wish to offer you is divided into 3 parts with a payment during the validation of each milestone. The milestones are the following : A. Develop on the FRDM K64 development board a biometric embedded system on one hand and develop a platform (preferably JAVA) associated with the biometric device and allowing the triggering of the functionalities on the biometric device on the other hand, B. Design a PCB for industrial production, C. Test the PCB after its manufacture in order to validate the entire mission. The description of the project. The project concerns a biometric device allowing to (1) protect against identity fraud, (2) protect data by encryption (encryption functionalities are not to be developed), (3) store encrypted data or not in the computer / Smartphone or in the biometric device, (4) recharge a Smartphone as a powerbank can do. The main functionalities to be developed for the biometric device and the software platform are: 1. User authentication, 2. File transfer via USB from the computer to the biometric device and vice versa (an automatic authentication of the device must be developed with a specific signature between the device and the platform) 3. Allow the user to choose the data encryption method, 5. Allow the user to choose whether the data should be encrypted or not when stored on the computer or the biometric device, 6. Switch on the device or put it on standby (with regard to the specifications described in the specifications) 7. Charge a smartphone with the biometric device (details of the constraints related to battery management in the specifications document). For the mission, a non-disclosure contract must be before the specifications are sent to you. A service contract will be signed with an obligation of result clause. To interest us, share your previous work on similar project, share your resume. No need to discuss if you cannot share those things. Best regards
