Technologies for 3D printing digital rights management (DRM) include a 3D printing device communicatively coupled with a 3D model storage server and a rights management server over a network. The 3D printing device may establish a model unlock engine in a first trusted execution environment and a key release engine in a second trusted execution environment. The model unlock engine may extract a content access policy and a content key from an encrypted 3D model and generate a content key request to the key release engine. The key release engine may validate the content key request and decrypt the content key in response to the content access policy being satisfied. The model unlock engine may further decrypt 3D model content included in the 3D model using the decrypted content key to facilitate the printing of the 3D model.

Technologies for determining a confidence of user authentication include authenticating a user of a computing device based on a set of authentication factors and a fusion function that fuses the set of authentication factors to generate an authentication result. A false accept rate and a false reject rate of the authentication result is determined, and an authentication confidence for the authentication result is determined. The authentication of the user is performed passively, without interruption or interruption of the user. If the authentication confidence is below a threshold value, an active authentication procedure may be performed.

Systems and techniques for securely managed location-and-tracking service (LTS) access are described herein. A trusted execution environment (TEE) may establish a connection to an LTS. The TEE may provide verification to the LTS that the connection origination from the TEE. The TEE may request an LTS location for the mobile device from the LTS using the connection. The TEE may provide the LTS location to applications of the mobile device.

A method and apparatus for dynamic provisioning of an access control policy in an input/output (I/O) controller hub are described. In one embodiment, the method includes the establishment of a control channel during evaluation stages of a network access request. In one embodiment, the control channel enables resource enumeration of a hardware platform while disabling data read/write processing of the hardware platform. Once resource enumeration is completed, conditional control settings for each enumerated platform resource are sent to a network policy decision point. Once transmitted, if the conditional control settings identify the hardware platform as having a non-compliant configuration, conditional control settings for at least one enumerated resource of the hardware platform are modified according to a received access control policy to provide compliance of the hardware platform configuration to enable network access. Other embodiments are described and claimed.

A data processing system may include a high integrity storage (HIS) device with a partition or cache that is protected from updates. The data processing system may perform a boot process in response to being reactivated. The boot process may include the operation of executing a boot object. During the boot process, before executing the boot object, the data processing system may retrieve a digest for the boot object from the protected cache of the HIS device. The digest may be a cryptographic hash value for the boot object. During the boot process, the retrieved digest may be extended into a platform configuration register in a trusted platform module of the data processing system. Other embodiments are described and claimed.

A manageability engine or adjunct processor on a computer platform may receive a request for activation and use of features embedded within that platform from a service provider authorized by the manageability engine's manufacturer. The manageability engine may initiate a request for authority through the service provider to a permit server. The permit server may provide, through the service provider, proof of the service provider's authority, together with a certificate identifying the service provider. Then the manageability engine may enable activation of the features on the platform coupled to the manageability engine, but only by the one particular service provider who has been authorized.

An antivirus (AV) application specifies a fault handler code image, a fault handler manifest, a memory location of the AV application, and an AV application manifest. A loader verifies the fault handler code image and the fault handler manifest, creates a first security domain having a first security level, copies the fault handler code image to memory associated with the first security domain, and initiates execution of the fault handler. The loader requests the locking of memory pages in the guest OS that are reserved for the AV application. The fault handler locks the executable code image of the AV application loaded into guest OS memory by setting traps on selected code segments in guest OS memory.

A management engine may be used to trap configuration cycles during the boot process and thereafter in response to operating system enumeration. As a result, a virtual bus device can be created. The bus device may be used to provision software to the platform even when the operating system is corrupted or non-functional.
