摘要： A data protection policy is implemented on a computing device, the data protection policy indicating how organization data on the computing device is to be protected. Protection of the organization data includes encrypting the organization data, and allowing the organization data to be decrypted only by particular programs and/or under particular circumstances (as indicated by the data protection policy). When implementing a data protection policy, files already stored on the computing device are encrypted using a passive encryption technique. The passive encryption technique can include one or more of an encrypt on close technique, an encrypt on open technique, an encrypt without exclusive access technique, and an encrypt location technique.

摘要： Content on a device is encrypted and protected based on a data protection key corresponding to a particular identity of the user of the device. The protected content can then be stored to cloud storage, and from the cloud storage the protected content can be transferred to various other ones of the user's devices. A data protection key that is used to retrieve the plaintext content from the protected content is maintained by the user's device. This data protection key can be securely transferred to other of the user's devices, allowing any of the user's devices to access the protected content.

摘要翻译： 设备上的内容基于对应于设备用户的特定身份的数据保护密钥进行加密和保护。 受保护的内容然后可以被存储到云存储器，并且从云存储器可以将受保护的内容传送到用户的各种其他装置。 用于从受保护内容中检索纯文本内容的数据保护密钥由用户设备维护。 该数据保护密钥可以安全地传输到其他用户的设备，允许任何用户的设备访问受保护的内容。
