Abstract: An improved search operation includes receiving, by a server computing device, an encrypted search query and cleartext metadata associated with the encrypted search query from a client computing device; performing a search using the encrypted search query to generate encrypted search results; and sending the encrypted search results to the client computing device.

Abstract: A method comprises receiving, from an input device, an input speech signal, encoding the input speech signal to generate a first homomorphically encrypted string, sending the homomorphically encrypted string to a remote device via communication link, receiving, from the remote device, a reply comprising a second homomorphically encrypted string, decoding the second homomorphically encrypted string into an output speech signal, and outputting the output speech signal on an audio output device.

Abstract: A method comprises receiving, from a remote device, a first encrypted data set encrypted using a first encryption scheme, performing a set of computations on the first encrypted data set to generate a first set of encrypted results, encrypting the first set of encrypted results using a second encryption scheme to generate a second set of encrypted results, sending the second set of encrypted results to the remote device, receiving, from the remote device, third set of encrypted results in which the first encryption scheme has been decrypted, and generating a set of decrypted results by applying a decryption algorithm to the third set of encrypted results to decrypt the second encryption scheme.

Abstract: Embodiments of the present invention provide a portable bioelectrochemical electrical signal measuring device that may have at least one anode, at least one cathode, an anode-cathode connector between said at least one anode and said at least one cathode, a load connector between a load and said at least one anode and at least one cathode, and a data meter connected to said load connector wherein the device may measure an electrical signal of a matrix to perhaps determine the microbial activity in the matrix.

Abstract: Graphene oxide (GO) is an emerging material for energy, environmental, and many other applications which in the past has been produced using chemical processes involving high-energy consumption and hazardous chemicals. Embodiments of the present invention focus on bioelectrochemical systems (BES) having microorganism(s), an anode (11) and cathode (14) to produce GO (13) from graphite, coal, and other carbonaceous materials under ambient conditions without chemical amendments. In some embodiments, value-added organic compounds (17) and even H2 (16) can be produced.
