Abstract: Presence based content access control techniques are described in which presence of users is used as a basis for enforcing content restrictions. In an implementation, applications are registered to receive feedback regarding users' presence in relation to a presentation of content via a computing device. The presence of users is recognized independently of authentication of the users to access user accounts. For example, an imaging sensor such as camera may be employed for recognition of multiple users engaged with the computing device. In addition or alternatively, presence devices associated with users such as badges, key fobs, or access cards may be detected to ascertain the presence of users. Feedback indicative of the one or more users that are recognized may then be supplied to the registered applications. The feedback enables the applications to control the presentation of content by enforcing content restrictions and/or taking other presence based actions.

Abstract: A system for bootstrap provisioning of a device is provided. A vouching device is provisioned to access a bootstrap account of a bootstrap account provider and a secondary account of a secondary account provider. The bootstrap account provider stores an indication of the secondary account, and the secondary account provider stores verification data to verify a certification of the vouching device. A target device is provisioned to access the bootstrap account of the bootstrap account provider. The target device receives from the bootstrap account provider an indication that the target device is provisioned with the secondary account provider. The target device directs generation of a certification by the vouching device of target authentication data of the target device. The target device then sends the certification to the secondary account provider to effect the provisioning of the target device to access the secondary account.

Abstract: A facility for enrolling a software implementer in a code signing. In one example facility, the facility receives information identifying the implementer, and credentials authenticating the implementer. The facility generates secret state for the implementer. Based on at least one or both of (1) at least a portion of the received credentials and (2) at least a portion of the generated secret state, the facility generates for the implementer a key pair comprising a private key and a public key, and persistently stores the secret state.

Abstract: Techniques and apparatuses for biometric gestures are described herein. In one or more implementations, a computing device includes a biometric sensor, such as a fingerprint touch sensor, that is configured to detect gesture input. When gesture input is received from a user, the biometric sensor detects biometric characteristics (e.g., a fingerprint) of the user and determines a gesture (e.g., a tap, touch and hold, or swipe) based on the gesture input. The user is authenticated if the biometric characteristics correspond to an authorized user of the device. If the user is authenticated, the device transitions to an authenticated user state that is associated with the type of gesture, such as by displaying personal information on a lockscreen of the computing device or opening a quick action center.

Abstract: Described herein are techniques for regulating access to a remote resource using two-factor authentication based on information regarding a host machine of a portable storage drive that stores an operating system that is booted by the host machine. The information regarding the host machine of a portable storage drive may be used as a second factor in a two-factor authentication. Such information regarding the host machine may include, in some embodiments, information retrieved from a secure storage of the host machine, such as from a cryptoprocessor of the host machine. The information may include an identifier for the host machine or may be a user credential pre-provisioned to the host machine to be used in two-factor authentication.

Abstract: The techniques and systems disclosed herein pertain to preventing unauthorized access to computing resources by unauthorized persons by deploying biometric security. To implement biometric security, the computing device, possibly by the OS, may obtain samples of one or more biometric factors unique to the owner. The computing device may construct pattern-matching templates corresponding to the biometric samples, which may be stored for later use when a protected resource is requested. Computing resources may be selected for protection by a biometric security mechanism by an authorized user or by other techniques or default settings. Before allowing certain restricted actions, the OS may request that the user provide one of the previously registered biometric samples. If the biometric sample matches the user's stored pattern-matching template, the OS may grant access to the computing resource, otherwise, the OS may deny access to the computing resource.

The feedback enables the applications to control the presentation of content by enforcing content restrictions and/or taking other presence based actions.

Abstract: Techniques described herein leverage a trusted entity within a domain to enable devices to establish trust with one another so they can securely discover each other and connect to one another. In various examples discussed herein, a device is configured to provide trust information to, and/or receive trust information from, the trusted entity. The trust information may include, for example, a public key of an encryption key pair, a certificate signed by the trusted entity proving authenticity, and/or a hash function and a hash seed used to compute a series of results that form a hash chain. The device may use the trust information to discover another device and to connect to the other device securely and automatically (e.g., with no user involvement or limited user involvement). Moreover, the device may use the trust information to dynamically change a MAC address being used to communicate with the other device.

Abstract: Computing devices utilizing trusted execution environments as virtual smart cards are designed to support expected credential recovery operations when a user credential, e.g., personal identification number (PIN), password, etc. has been forgotten or is unknown. A computing device generates a cryptographic key that is protected with a PIN unlock key (PUK) provided by an administrative entity. If the user PIN cannot be input to the computing device the PUK can be input to unlock the locked cryptographic key and thereby provide access to protected data. A computing device can also, or alternatively, generate a group of challenges and formulate responses thereto. The formulated responses are each used to secure a computing device cryptographic key. If the user PIN cannot be input to the computing device an entity may request a challenge. The computing device issues a challenge from the set of generated challenges.

Abstract: Described herein are techniques for regulating access to a portable storage drive, that stores an operating system securely, using information regarding a host machine. In accordance with some of the techniques described herein, when a portable storage drive that stores an operating system securely is to be accessed by a host machine, information regarding the host machine, such as information regarding the hardware of the host machine, may be retrieved and evaluated to determine whether to grant access to the host machine. When the host machine is granted access, the host machine may access secured data stored on the portable storage drive in any suitable manner. In some cases, accessing the secured data may include decrypting the secured data and transferring decrypted data to another storage of the host machine. The decrypted information may include an operating system that is booted by the host machine.
