Abstract: Systems and methods for hashing ordinals under a modified blockchain protocol for blockchain events following ordinal theory. Ordinal identifiers are assigned to unspent inputs for a blockchain event. Content associated with multiple ordinals are embedded into data fields of the unspent inputs, which are then transferred to blockchain event outputs. The blockchain event outputs, including the embedded content associated with the multiple ordinals, are hashed into a block, which is broadcasted for appending to a blockchain data structure according to the modified blockchain protocol.

Abstract: Systems and methods for implementing privacy-preserving aggregation of federated data are disclosed. Clients may share sets of private values encoded in different local domains with an aggregator, where privacy of the local domains is preserved. The aggregator merges the shared sets into an aggregated set that includes non-unique values and derives a global domain for the aggregated set. The aggregator then shares mappings between input sets and the global domain with the respective clients while preserving privacy for the global domain. The clients may then encode private datasets for aggregation using the respective mappings.

Abstract: A video conferencing framework based on face restoration uses information such as pose and expressions instead of using information from different source frames and driving frames. In an embodiment, this information comes from the current target frame. In another embodiment, the proposed system uses a discrete codebook-based representation comprising a generic branch that generates and transmits an integer vector indicating the indices of codewords, from which the decoder retrieves a rich high-quality codebook-based feature based on the same shared codebook with an encoder. An adaptive branch optionally provides additional detailed fidelity and expressive features using a low-quality low-bitrate downsized face input and further aggressively compressed. The low-quality feature is weighted and combined with the high-quality feature for final reconstruction.
