Various embodiments provide a method and an apparatus for determining a trust status of a TPM, and a storage medium, and pertains to the field of data security technologies. In those embodiments, a verifier send an unsealing request to a host, so that the host unseals current PCR values in the TPM based on a seal key handle carried in the unsealing request, and sends verification information to the verifier based on the unseal verification key obtained after the unsealing. Therefore, any verifier that establishes an encrypted channel with the host can determine the trust status of the TPM in the host based on a second verification key transmitted on the encrypted channel, and there is no need to pre-deploy a remote attestation server to determine the trust status of the TPM.

Method and apparatus for determining trust status of TPM, and storage medium

An intruder detection method is provided, comprising a security server sending a verification prompt to a device in a controlled-access area, based on an entry indication of an entrant into the controlled-access area, with the verification prompt indicating the entrant should perform a predefined verification action, the security server receiving entrant behavior information, the security server comparing the entrant behavior information to a behavior model of a set of authorized persons associated with the controlled-access area, with the behavior model including the verification prompt, and the security server generating an intruder indication if the entrant behavior information does not match a behavior sequence included in the behavior model.

Intruder detection method and apparatus

A 2D/3D switchable stereoscopic display apparatus includes a display panel, a liquid crystal lens, and a controller. The liquid crystal lens includes a first substrate having a plurality of first electrodes, a second substrate disposed opposite to the first substrate and having a second electrode, a liquid crystal layer constituting liquid crystal molecules disposed between the first substrate and the second substrate, and a plurality spacers. The controller is configured to, when the display apparatus is in a 2D display state, control a first voltage between the first electrodes and the second electrode to generate a first electric field with an equal electric field intensity, which causes the liquid crystal molecules to rotate by a predetermined degree such that a refractive index difference between the liquid crystal molecules and the spacers is within a preset range.

2D/3D switchable stereoscopic display apparatus

A three-dimensional (3D) display apparatus is provided for displaying a 3D image. The 3D display apparatus includes a display panel and a grating device coupled to the display panel. The display panel includes a plurality of display pixels arranged in a two-dimensional array, and each pixel includes multiple sub-pixels. The grating device includes a plurality of grating elements based on liquid crystal to guide lights associated with the plurality of display pixels into predetermined viewing directions. Further, the grating device is one of a lenticular lens grating and a slit grating, and the plurality of grating elements are arranged in parallel. The plurality of grating elements cover the plurality of display pixels and are tilted at an inclination angle with respect to the display pixels, and each grating element comprises a plurality of electrodes arranged at the inclination angle. Further, a width of the electrodes is less than or equal to a width of a sub-pixel and a width between any two electrode is less than or equal to a sub-pixel.

Autostereoscopic display apparatus and method

A method and a system for controlling quality of service of a storage system, and a storage system. The method includes: collecting information about processing capabilities of the hard disks in the storage system and obtaining processing capabilities of the hard disks according to the information about processing capabilities; dividing a cache into multiple cache tiers according to the processing capabilities of the hard disks; and writing, for a cache tier in which dirty data reaches a preset threshold, data in the cache tier into at least one hard disk corresponding to the cache tier. The method avoids a phenomenon of preempting page resources in the cache.
