摘要： A file system is configured for use with files protected by digital rights management (DRM) content controls and to interact both with applications that are, and are not, DRM aware. The file system may be configured for use by two applications, in a manner that may provide the second application with protected files if the first application was previously allowed access. In one example, a user context cache of DRM-protected files is created. The files in the cache may have been decrypted in response to a request(s) from the first application. Subsequent requests from the second application may be received for files within the user context cache of DRM-protected files. At least one of the files within the user context cache of DRM-protected files may be provided to the second application if the second application has a joint user context with the first application.

摘要： An exemplary system enabling credential roaming among a plurality of different computing devices may include an event handler to receive event notifications such as, e.g., a client logon. The event handler may invoke a management service in response to receiving an event notification. The management service may include a synchronizing module to synchronize a user's credentials with a remote directory service, such as, e.g., Active Directory, so that the user's credentials are available from any of a number of different computing devices.
摘要翻译：允许在多个不同计算设备之间进行凭证漫游的示例性系统可以包括用于接收事件通知的事件处理程序，例如客户端登录。响应于接收到事件通知，事件处理程序可以调用管理服务。管理服务可以包括同步模块，以将用户的凭证与例如Active Directory的远程目录服务同步，使得用户的凭证可从多个不同的计算设备中的任何一个获得。

摘要： Systems and methods for managing multiple keys for file encryption and decryption may provide an encrypted list of previously used keys. The list itself may be encrypted using a current key. To decrypt files that are encrypted in one or more of the previous keys, the list can be decrypted, and the appropriate previous key can be retrieved. To re-key files, an automated process can decrypt any files using previous keys and encrypt them using the current key. If a new current key is introduced, the prior current key can be used to decrypt the list of keys, the prior current key can be added to the list, and the list can be re-encrypted using the new current key.
摘要翻译：用于管理用于文件加密和解密的多个密钥的系统和方法可以提供先前使用的密钥的加密列表。列表本身可以使用当前密钥进行加密。要解密在一个或多个先前密钥中加密的文件，可以解密该列表，并且可以检索相应的上一个密钥。要重新启动文件，自动化过程可以使用先前的密钥解密任何文件，并使用当前密钥进行加密。如果引入新的当前密钥，则可以使用先前的当前密钥来解密密钥列表，可以将先前的当前密钥添加到列表中，并且可以使用新的当前密钥重新加密列表。

摘要： Use of a biometric identification device in a client computer system to subsequently access an authentication system includes receiving biometric sample data which is digitally signed and combining the data with a user ID and PIN. This package of data is then securely transmitted to a biometric matching server to validate the user and the biometric sample. Once validated, the biometric matching server return the data package plus a temporary certificate and a public/private key pair to the client computer. The client computer may then use this information to access an authentication system to subsequently gain access to a secure resource.

摘要： Protecting content. A recipient receives content from a publisher. Some content is managed by an access server. The access server controls the recipient's use of managed content through interaction with a trusted agent at the recipient. The content is encrypted to a content key, and the content is associated with policy information. The policy information includes the content key for decrypting the content. The policy information is encrypted to an access server key allowing the policy information to be decrypted by the access server. The content key is received from the access server. The content key is encrypted to a trusted agent key. The content key is further encrypted to additional factor(s) defining additional content protection beyond that provided by trusted agent. The content key is decrypted using the trusted agent key and the at least one additional factor. The content is decrypted using the content key.

摘要： File system interaction with digital rights management (DRM) is facilitated by enabling one or more file system components to be DRM-aware. These one or more file system components may be part of a computer operating system. An exemplary system implementation includes: one or more processors; and one or more media in operative communication therewith, the media storing one or more file system components that are configured to provide content having DRM controls to a requesting program in either a raw form or a decrypted form in dependence on whether the DRM controls comprise simple DRM content controls or complex DRM content controls. In another exemplary system implementation, the one or more file system components are configured to provide files with simple DRM content controls to requesting applications in a decrypted form and to provide files with complex DRM content controls to requesting applications in an unaltered form.

摘要： One aspect relates to a process and associated device that provides a private key of an asymmetric key pair in a key device. A symmetric master key is derived from the private key of the asymmetric key pair. The symmetric master key is stored in a computer memory location. The symmetric master key is used to encrypt or decrypt a file encryption key. The file encryption key can encrypt or decrypt files. In another aspect, the user can still access the files even if a user deactivates the key device by encrypting or decrypting the file encryption key directly from the symmetric master key.
