Abstract: A system and method for providing cryptographic operation service in a virtualization environment. In the system, a configuration subsystem provides an interface for an administrator and a common user to input information about a virtual cryptographic device. A key file storage subsystem stores a key file and protects it with the protection password. A virtual machine operating subsystem obtains a corresponding key file from the storage subsystem according to the input of the configuration subsystem, creates a virtual device for a guest virtual machine, and finally operates the guest virtual machine to provide cryptographic computing service for the guest virtual machine. Thus the administrator/the common user can specify a key file and input a protection password for a guest virtual machine via the corresponding interface to facilitate the creation of a virtual cryptographic device, and can manage the virtual cryptographic device in a user-friendly and centralized manner.

Abstract: The present invention includes a system and methods for image searching. Embodiments of the system integrate textual features and visual features for improved search performance. The system represents text terms in the visual feature space and develops a text-guided weighting scheme for visual features. The weighting scheme infers intention from query terms and enhances the visual features that are significant in light of such intention.
