Abstract: Techniques are disclosed relating to biometric authentication, e.g., facial recognition. In some embodiments, a device is configured to verify that image data from a camera unit exhibits a pseudo-random sequence of image capture modes and/or a probing pattern of illumination points (e.g., from lasers in a depth capture mode) before authenticating a user based on recognizing a face in the image data. In some embodiments, a secure circuit may control verification of the sequence and/or the probing pattern. In some embodiments, the secure circuit may verify frame numbers, signatures, and/or nonce values for captured image information. In some embodiments, a device may implement one or more lockout procedures in response to biometric authentication failures. The disclosed techniques may reduce or eliminate the effectiveness of spoofing and/or replay attacks, in some embodiments.

Abstract: Some embodiments of the invention provide a program for recovering access to a service associated with an account. The program provides a login credential to log into the account to receive the associated service. Next, the program receives an access continuation parameter (ACP) after logging into the account. The program then accesses the service and receives a rejection of a subsequent access to the service. The program then provides the ACP in lieu of the login credential to continue to receive the service.

Abstract: The present disclosure describes techniques for changing a required authentication type based on a request for a particular type of information. For example, consider a situation where a user has asked a virtual assistant “who owns this device?” By default, the device may allow biometric authentication to unlock. In response to identification of the owner by the virtual assistant, however, the device may require one or more other types of authentication (e.g., manual entry of a passcode) to unlock the device. In various embodiments, the disclosed techniques may increase the security of the device by making it more difficult for malicious entities to obtain the sensitive information or to access device functionality once the sensitive information has been disclosed. In various embodiments, this may prevent or reduce unauthorized access to the device.

Abstract: Some embodiments provide an account-access recovery method that receives a request to recover access to an account. The method also assesses recent usage of a device that is associated with the account. The method also, based on the assessment, selects a recovery process from a group of different recovery processes for regaining access to the account. The method also provides the selected recovery process to a party that is requesting the access recovery.

Abstract: In response to a request for launching a program, a list of one or more application frameworks to be accessed by the program during execution of the program is determined. Zero or more entitlements representing one or more resources entitled by the program during the execution are determined. A set of one or more rules based on the entitlements of the program is obtained from at least one of the application frameworks. The set of one or more rules specifies one or more constraints of resources associated with the at least one application framework. A security profile is dynamically compiled for the program based on the set of one or more rules associated with the at least one application framework. The compiled security profile is used to restrict the program from accessing at least one resource of the at least one application frameworks during the execution of the program.

Abstract: The subject disclosure provides systems and methods for application-specific network data filtering. Application-specific network data filtering may be performed by a sandboxed process prior to providing the network data to an application to which the network data is directed. Any malicious or otherwise potentially harmful data that is included in the network data may be removed by the application-specific network data filter or may be allowed to corrupt the application specific network data filtering operations within the sandbox, thereby preventing the malicious or harmful data from affecting the application or other portions of an electronic device. In one or more implementations, a first process such as an application-specific network data filtering process may request allocation of memory for the first process from second process, such as an application, that is separate from a memory manager of the electronic device.
