Abstract: Embodiments described herein ensure differential privacy when transmitting data to a server that estimates a frequency of such data amongst a set of client devices. The differential privacy mechanism may provide a predictable degree of variance for frequency estimations of data. The system may use a multibit histogram model or Hadamard multibit model for the differential privacy mechanism, both of which provide a predictable degree of accuracy of frequency estimations while still providing mathematically provable levels of privacy.

Abstract: Embodiments described herein provide a privacy mechanism to protect user data when transmitting the data to a server that estimates a frequency of such data amongst a set of client devices. In one embodiment, a differential privacy mechanism is implemented using a count-mean-sketch technique that can reduce resource requirements required to enable privacy while providing provable guarantees regarding privacy and utility. For instance, the mechanism can provide the ability to tailor utility (e.g. accuracy of estimations) against the resource requirements (e.g. transmission bandwidth and computation complexity).

Abstract: Modifying a notification on one client device can trigger the generation and transmission of a silent notification to another client device that is associated with the same user account. The silent notification can include instructions to query for and modify a similar notification, if present, on the other client device. Silent notifications that are undeliverable can be stored in offline storage and delivery can be reattempted at a later point in time.

Abstract: Systems and methods are disclosed for generating term frequencies of known terms based on crowdsourced differentially private sketches of the known terms. An asset catalog can be updated with new frequency counts for known terms based on the crowdsourced differentially private sketches. Known terms can have a classification. A client device can maintain a privacy budget for each classification of known terms. Classifications can include emojis, deep links, locations, finance terms, and health terms, etc. A privacy budget ensures that a client does not transmit too much information to a term frequency server, thereby compromising the privacy of the client device.

Abstract: Systems and methods are disclosed for a server learning new words generated by user client devices in a crowdsourced manner while maintaining local differential privacy of client devices. A client device can determine that a word typed on the client device is a new word that is not contained in a dictionary or asset catalog on the client device. New words can be grouped in classifications such as entertainment, health, finance, etc. A differential privacy system on the client device can comprise a privacy budget for each classification of new words. If there is privacy budget available for the classification, then one or more new terms in a classification can be sent to new term learning server, and the privacy budget for the classification reduced. The privacy budget can be periodically replenished.

Abstract: An invitation service performs a series of transactions to enable P2P communication between two or more mobile data processing devices. Prior to attempting to establish a P2P network communication channel, the invitation service may first collect network information for each of the mobile devices and use the network information to determine if a direct P2P network communication channel is feasible. If a direct connection is feasible, then the invitation service provides for direct P2P communication, pushing the necessary network information to each of the mobile devices. If a direct connection is infeasible, or an attempted direct connection fails, then the invitation service may identify network information associated with a relay service. The network information may then be used by any pair of mobile devices to establish a connection through the relay service. The invitation service can perform its functions without maintaining per-connection state information for the mobile devices.

Abstract: Registering a client computing device for online communication sessions. A registration server receives a message that has a push token that is unique to the client computing device and a phone number of the client computing device from an SMS (Short Message Service) transit device, which received an SMS message having the push token from the client computing device and determined the phone number of the client computing device from that SMS message. The registration server associates the push token and the phone number and stores it in a registration data store, which is used for inviting users for online communication sessions.
