基于Android密码管理器的安全输入法研究与实现

Research and implementation of security input method based on Android password manager

移动互联网时代,用户的在线认证密码不断增多,导致记忆困难。移动端密码管理器是帮助用户管理各种密码并实现跳转填充功能的应用软件。已有的众多Android端密码管理器广泛使用系统剪贴板传递和填充密码,这使得信息安全遭受严重威胁。文中基于Android操作系统开发了一种内嵌于密码管理器的安全输入法,该输入法既满足了输入要求,又能够摒弃剪贴板实现密码的安全传递与填充。

In the mobile Internet era, the number of users ＇ online authentication passwords are increasing,resulting in memory difficulties. Mobile terminal password manager is a software which can help users manage a variety of passwords and jump to achieve the fill function. Many existing Android password managers widely use the system clipboard to transmit and fill passwords,which makes the information security to be seriously threatened. Based on the Android operating system,this paper develops a security input method which is embedded in the Android password manager. The input method can not only fulfills the input requirements, but also abandons the clipboard to achieve secure transmission and secure filling of passwords.
