    • A system for using accelerometer-based detection of physical movement for document sharing provides easy and intuitive ways to securely share documents, even without passwords, between computing devices. The system of the present invention includes: at least two computing devices that each have a motion detection device capable of detecting sudden movements and generating a unique signature. The unique signature can then be used to generate signatures or shared secrets for controlling the transfer of data between devices. The motion detection device is capable of detecting sudden movement such as the tapping of the two computing devices together, tapping a stack of computing devices, tossing a computing device in the air. The system may optionally include an intermediary device such as a server for transferring the documents or files between computing devices such that only a small decryption key and file pointer is needed to share records between computing devices. The present invention also includes a novel method for accelerometer-based detection of movement for transferring data between computing devices.
    • 使用基于加速度计的物理移动检测的系统可以提供简单而直观的方法来安全地共享计算设备之间的文档,即使没有密码。 本发明的系统包括:至少两个计算设备,每个计算设备具有能够检测突然移动并产生唯一签名的运动检测设备。 然后可以使用唯一签名来生成用于控制设备之间的数据传输的签名或共享秘密。 运动检测装置能够检测突然移动,例如两个计算设备的敲击在一起,敲击一堆计算设备,将计算设备折叠在空中。 系统可以可选地包括诸如用于在计算设备之间传送文档或文件的服务器的中间设备,使得仅需要小的解密密钥和文件指针来在计算设备之间共享记录。 本发明还包括用于在计算设备之间传送数据的用于基于加速度计的移动检测的新方法。
