I have difficulty to find a practicum idea for computer security or smartphone security.
I need help to find a good idea and to write a proposal for it.
the idea should be like develop a tool for smartphone or to ac computer that deal with a security issue.
Currently mobile security issues directly related to the security of the user data on the device and at the time of transmission or reception. Protection of user data - the best idea for the software from the category of security. There are several variations for implementing such a program.
First, you can develop a protocol for which data will be transmitted in encrypted form. Now already implemented many of these solutions (SSL, HTTPS), therefore, it is necessary to examine their weaknesses and correct them in developing your own software. The result will look like a program for smartphone/tablet , which allows to communicate and transfer files at a secure protocol. It is appropriate here to look in the direction of decentralized networks, ie without connecting the server. Clients there would use p2p etc.
Secondly , it is possible to develop a program designed for the data on the device. Here you can solve backup problems periodically comparing versions of files and uploading them to the server. Also, relevant to lock the device in case of theft or loss, followed by reduction of the data backup and monitoring devices via GPS.
