The Design and Implementation of Password protection in Android platform
[Abstract] With the Android phones, more and more popular, security and convenience become the focus of users.We need a software that can help users manage a variety of accounts and password,such as: bank cards,credit cards,various VIP cards,micro-blogging,Emails and so on. Password protection software based on Android operating system has the advantage of fast installation and easy operation .This paper discussed how to store user data and its encryption,based on the theory and development experience of Android operating system and Java encryption and decryption. Through the encryption and decryption of the existing ideas and methods of learning to achieve the password management based on Android operating system ; to achieve a database file backup and recovery; to achieve the data encryption and decryption. In the end, the password protection software was tested, showing that we achieved the expected results.
