US Classification:

705 739, 705347, 345440, 705 711

Abstract:

According to some embodiments, data may be received from a plurality of remote data sources. The received data may be, for example, associated with a plurality of social and traditional media sources. The received data may be aggregated based on an association with an entity and stored. At least two superimposed graphs may then be automatically provided on a user display, including (i) a first graph having an x-axis representing time and a y-axis representing an amount of social networking activity in the aggregated data and (ii) a second graph having an x-axis shared with the first graph and a y-axis representing a financial value associated with the entity.

Abstract:

A method for searching an encrypted file comprises: receiving a query from a first device of a set of devices; tokenizing the query; searching the encrypted file, without decrypting the file, for the tokenized query; aggregating results of the search; and outputting the aggregated results. The searching includes checking a bloom filter of an index of the encrypted file. The index includes a file public secret (R), a proof of work for the file secret (Rproof), a multipart threshold public encryption key (LKe-pub), a multipart threshold public search key (LKs-pub), and the bloom filter. The bloom filter including index values that are elliptic curve paired between a curve-hashed token of the encrypted file and the product of the encrypted file's ephemeral secret value (r) and the multipart threshold public search key (LKs-pub).

Abstract:

A method comprises: tokenizing, at a first device, a search query; creating search requests and send to delegate devices, each search request including a public key encrypted message containing the tokenized search query and index identifiers of indices to be searched; computing search responses to the search requests, each search response comprising a partial trapdoor computed per token per identifier; transmitting the search responses to the first device; recombining, at the first device, the search responses per identifier per token; performing a ranked set of queries against the indices; and returning the search results in order of relevancy.
