Proposal of a mobile-phone-based security system for bank applications
With the importance of the applications contained in cell phones, the scenario of Brazilian urban violence and the technological elements already existing in the market, this work aims to relate these three topics to propose a low-cost system that seeks to block financial actions by through the cell phone when the user is not using it near the device, without letting other applications lose their functionality, adding another layer of security to the access. In this way, when approaching a possible assault or theft, the criminal will not be able to carry out any type of banking activity, since the proposed device will not be close to the cell phone. In this way, the bandits can remain in the hands of the device, but without the possibility of carrying out lightning kidnappings or possible momentary coercions, increasing the level of security, at least regarding the values present in the bank account. Currently, there are already devices that carry out this communication, changing some cell phone functionalities as NFC, and this equipment is an opportunity to adapt it to the project proposal.
