    • This is directed to a digital handshake for establishing a secure communications path between two electronic devices. Each device can capture an image of the other device using a camera (e.g., a front facing camera or a back facing camera) and extract, from the captured image, a key or seed associated with the other device. For example, each device can display a seed to be identified from an image taken by the other device. Using the extracted keys or seeds, each device can generate, using a same process, an identical digital handshake key. The digital handshake key can then be used to define a secure communications path between the two devices and share information securely. In some embodiments, a digital handshake key can be shared among several devices to create a multi-device secure communications path. Once a communications path has been established, the devices in the path can be identified and authenticated from the digital handshake key to receive access to secured goods, services or information.
    • 这是针对用于在两个电子设备之间建立安全通信路径的数字握手。 每个设备可以使用相机(例如,面向前的相机或背面照相机)捕获另一设备的图像,并从捕获的图像中提取与另一设备相关联的键或种子。 例如,每个设备可以从由另一设备拍摄的图像显示要识别的种子。 使用所提取的键或种子,每个设备可以使用相同的过程生成相同的数字握手键。 然后,数字握手密钥可用于定义两个设备之间的安全通信路径,并且可以安全地共享信息。 在一些实施例中,数字握手密钥可以在多个设备之间共享以创建多设备安全通信路径。 一旦建立了通信路径,路径中的设备就可以从数字握手密钥中识别和认证,以接收对安全的商品,服务或信息的访问。
