Publication number: 20160171228Abstract: A method to obfuscate the accurate detection of demographic information of a new user who provides ratings to a digital content service having a recommender system includes training an inference engine to detect the 5 demographic information. The training set includes movie ratings and demographic information from a plurality of other users. The new user inputs ratings, such as movie ratings, and the inference engine determines the demographic information of the new user. An obfuscation engine then adds movie ratings to the recommender system which cause an inference engine in the recommender system to fail to accurately detect the demographic information of the new user.Type: ApplicationFiled: June 10, 2013Publication date: June 16, 2016Inventors: Smriti Bhagat, Udi Weinsberg, Stratis Ioannidis, Nina Taft

Publication number: 20160020898Abstract: A hybrid approach to privacy-preserving ridge regression is presented that uses both homomorphic encryption and Yao garbled circuits. Users in the system submit their data encrypted under a linearly homomorphic encryption. The linear homomorphism is used to carry out the first phase of the algorithm that requires only linear operations. The output of this phase generates encrypted data, in a form that is independent of the number of users n. In a second phase, a Yao garbled circuit that first implements homomorphic decryption and then does the rest of the regression algorithm (as shown, an optimized realization can avoid decryption in the garbled circuit) is evaluated. For this step a Yao garbled circuit approach is much faster than current fully homomorphic encryption schemes. Thus the best of both worlds is obtained by using linear homomorphisms to handle a large data set and using garbled circuits for the heavy non-linear part of the computation.Type: ApplicationFiled: September 25, 2013Publication date: January 21, 2016Inventors: Valeria NIKOLAENKO, Udi WEINSBERG, Stratis IOANNIDIS, Marc JOYE, Nina TAFT

Publication number: 20150339687Abstract: The current methods and apparatus provide a system that learns a private attribute, such as gender, based on at least one iteration of presenting an item to a user and receiving ratings from the user for this item. In an exemplary embodiment, the system may solicit ratings for strategically selected items, such as movies for example, and then infers the user's gender. Based on the assessed confidence in the demographic selected, the system may repeat the selection, presentation and ratings of another item. The proposed system can strategically select the sequence of items that are presented to the user for a rating. By selecting the next item to be rated based on a maximum posterior probability confidence, a demographic with a certain threshold of confidence can be inferred. The inventive arrangements are based on novel usage of Bayesian matrix factorization in an active learning setting.Type: ApplicationFiled: December 12, 2013Publication date: November 26, 2015Inventors: Stratis IOANNIDIS, Udi WEINSBERG, Smriti BHAGAT

Publication number: 20150324820Abstract: Existing recommendation systems leverage user social and demographic information, e.g., age, gender and political affiliation, to personalize content and make recommendations. However, users do not volunteer this information due to privacy concerns or to the lack of initiative in filling out their profile information. The current methods and apparatus provide principles in which the system may learn the private attribute for those users who do not voluntarily disclose them. In an exemplary embodiment, the system receives ratings for items, such as movies, for example, that may be used by a recommendation system. The inventive arrangements are based on novel usage of Bayesian matrix factorization in an active learning setting. Such a system can be carried out using significantly fewer rated items than previously proposed static inference methods. The system functions effectively without sacrificing the quality of the regular recommendations made to the user.Type: ApplicationFiled: December 12, 2013Publication date: November 12, 2015Inventors: Stratis Ioannidis, Udi Weinsberg, Smiriti Bhagat

Publication number: 20150161628Abstract: A method for recommending at least one element of an audio-visual program commences by first determining the success of an audio-visual program composed of a set elements initially selected by a user. Thereafter, a replacement element is substituted for at least one of the initially selected elements and the success of the audio-visual program with the replacement element is determined. Thereafter, the replacement element is recommended for substitution in place of the at least one initially selected element if substituting replacement element in the audio-visual program yields greater success.Type: ApplicationFiled: December 6, 2013Publication date: June 11, 2015Inventors: Udi WEINSBERG, Smriti Bhagat
