Provision of anonymous context information and generation of targeted content

摘要

Embodiments of the present disclosure are directed towards selective disclosure of user or computing environment attributes to facilitate generation and/or provision of targeted content. In various embodiments, a likelihood that disclosure of an attribute of a user or of a computing environment associated with the user will enable identification of the user may be determined based on an associated population count of users or computing environments sharing the same attribute. In various embodiments, the attribute may be selectively disclosed to a content provider configured to provide targeted content, or a recommendation may be selectively provided to the user as to whether the user should disclose the attribute to the content provider, based on the determination and a risk tolerance associated with the user. In various embodiments, a dimension authority may track and make available population counts of users or computing environments having various attributes.

主权项

1. At least one non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by a computer device, enable the computer device to operate a context information manager to manage interactions between computing environments on computer devices, with enhanced privacy protection for a user of one of the computing environments, the context information manager to:
obtain with enforced thread and memory access isolation, from a dimension authority, one or more dimensions, each of the one or more dimensions including an attribute of the computing environment associated with the user and associated population count of computing environments sharing that attribute, wherein the one or more dimensions are signed by the dimension authority using a public key corresponding to a private key; with enforced thread and memory access isolation, authenticate itself to the dimension authority using an enhanced privacy identifier (“EPID”) to facilitate secure provision of the one or more dimensions by the dimension authority to the context information manager without disclosing the user's identity to the dimension authority, wherein the EPID comprises the private key, wherein the private key is provisioned to the computer device during manufacture of the computer device; determine a likelihood that disclosure of the attribute of the computing environment associated with the user will enable identification of the user, based on an associated population count of computing environments sharing the same attribute; and selectively disclose the attribute to a content provider in another computing environment configured to provide targeted content based on the determination and a risk tolerance associated with the user; wherein enforced thread and memory access isolation comprises a sign-and-mac (“SIGMA”) exchange, wherein at least one message in the SIGMA exchange by the computer device is signed with the private key.
