Abstract: A software trusted platform module (sTPM) operates in a hypervisor, receives trust assurances from specialized hardware, and extends this trust such that the hypervisor performs trust attestation. The hypervisor receives a startup sequence validation from a TPM, or Trusted Platform Module. The TPM performs bus monitoring during a boot sequence of the computer system, records the startup sequence from the bus, and performs a hash on the sequence. The TPM performs an authentication exchange with the hypervisor such that the hypervisor authenticates the attestation of the computer system from the TPM, and the hypervisor, now delegated with trust assurances from the TPM, provides assurances to users via an authentication chain. The ATCB then performs the attestation of the computer system according to the attestation protocol much faster than the TPM. In this manner, the hypervisor operates as a software delegate of the TPM for providing user assurances of trust.

Abstract: An isolation method for a management virtual machine and an apparatus, which resolves problems that performance of communication between service components is deteriorated, more resources are required for running a virtual machine, and security of the service components is relatively low. The method includes: acquiring a guest identifier; searching, according to the guest identifier, the management virtual machine for a kernel virtual machine; when the kernel virtual machine is not found in the management virtual machine, creating the kernel virtual machine in the management virtual machine; dividing a service provided for a guest virtual machine by the kernel virtual machine into multiple service components; and running the multiple service components in execution environments corresponding to permission of the service components, where the kernel virtual machine includes the multiple execution environments, and the multiple execution environment have different permission.

Abstract: The present invention discloses a method, an apparatus, and a system for triggering virtual machine introspection, so as to provide a timely and effective security check triggering mechanism. In the present invention, data that needs to be protected is determined; the data that needs to be protected is monitored; and when it is determined that the data that needs to be protected is modified, virtual machine introspection is triggered. The present invention avoids a performance loss and a security problem that are brought about by regularly starting a virtual machine introspection system to perform a security check, and therefore, the present invention is more applicable.

Abstract: A method, an apparatus, a terminal, and a server for synchronizing a terminal mirror are provided. The method includes: obtaining, by a terminal, multiple input events during running of application software; aggregating the multiple input events to obtain an aggregate event; and transmitting the aggregate event to the server, so that after parsing the aggregate event to obtain the multiple input events, the server processes the multiple input events by using a virtual machine that is of the terminal and set on the server, so as to obtain user data generated during the running of the application software. In the present invention, the terminal transmits the input events to the server in an event-driven manner, so that the server obtains the user data that is the same as that on the terminal that runs the application software, thereby ensuring that the server can back up complete user data.

Abstract: A method and apparatus for screening documents such as bank notes 1 for suitability for continued circulation, in which a damage index is computed for each document from a number of factors comprising a shape factor, an orientation factor, a size factor and a location factor developed for each defect in the document. Shape and rotation factors are obtained by applying Fourier and/or Wavelet transforms to sets of contour signals developed on scanning a document for defects using an optical scanner (6).
