Abstract: Technologies for distributed single sign-on operable to provide user access to a plurality of services via authentication to a single entity. The distributed single sign-on technologies provide a set of authentication servers and methods for privacy protection based on splitting secret keys and user profiles into secure shares and periodically updating shares among the authentication servers without affecting the underlying secrets. The correctness of the received partial token or partial profiles can be verified with non-interactive zero-knowledge proofs.

Abstract: Techniques for an image-based CAPTCHA for object recognition are described. The disclosure describes adding images to a database by collecting images by querying descriptive keywords to an image search engine or crawling images from the Internet.The disclosure describes generating the image-based CAPTCHA. The image is retrieved from the database, along with objects having significant values. An object is cropped from its image. The portion on the image where the object has been cropped is filled with image inpainting. The process obtains other objects from the database. The object is mixed among the other objects to from a set of candidate objects. A user is asked to select “the object” from the set of candidate objects that fits or matches the image. The image-based CAPTCHA evaluates whether a response, the selection, is from a human or a bot.

Abstract: Technologies for a human computation framework suitable for answering common sense questions that are difficult for computers to answer but easy for humans to answer. The technologies support solving general common sense problems without a priori knowledge of the problems; support for determining whether an answer is from a bot or human so as to screen out spurious answers from bots; support for distilling answers collected from human users to ensure high quality solutions to the questions asked; and support for preventing malicious elements in or out of the system from attacking other system elements or contaminating the solutions produced by the system, and preventing users from being compensated without contributing answers.

Abstract: A cross-module detection system and method for detecting and monitoring control flow transfers between software modules in a computer system. The system and method detect and monitor control flows entering and exiting the software modules. For a particular module, a checking model is extracted from the binary file of that module. In addition, a relaxed shadow stack is generated. If the module is an original module, meaning that the control flow originated from that module, then the checking model is used to check the validity of the control flow transfer. Otherwise, the relaxed shadow stack is used. An interception module is used to intercept and terminate invalid control flow transfers. If an invalid control flow transfer is detected, then the transfer is terminated. Otherwise, the control flow transfer is allowed to continue.

Abstract: Techniques for generating, updating, and transmitting a structure-based data representation of a document are described herein. The structure-based adaptive document caching techniques may effectively eliminate redundancy in data transmission by exploiting structures of the document to be transmitted. The described techniques partitions a document into a sequence of structures, differentiate between cache-worthy structures and cache-unworthy structures, and generating a structure-based data representation of the document. The techniques may transmit updated structures and instructions, instead of all data of the document, to update previously cached structures at a client device; thereby resulting in higher cache hit rates.
