| 20140241187 | SYSTEMS AND METHODS FOR AVOIDING INTERFERENCE FOR A PEER-TO-PEER NETWORK CONNECTION - Systems and methods are described herein for avoiding interfering with 5 GHZ frequency band signals with a peer-to-peer wireless local area network connection. A peer-to-peer client is notified of radar signals in proximity to the client over a master-to-client wireless local area connection with an enterprise access point. If the notification includes a non-interfering radar channel, the peer-to-peer client resets the peer-to-peer channel to the non-interfering radar channel. If the notification does not provide a non-interfering radar channel, the peer-to-peer client resets the peer-to-peer network connection to a non-dynamic frequency selection channel and may disconnect the Wi-Fi connection with the enterprise access point. | 08-28-2014 |
| 20140281477 | Secure Cloud Storage and Encryption Management System - An embodiment of the invention allows a user to back-up/store data to a cloud-based storage system and synchronize that data on the user's devices coupled to the storage system. The devices have secure out-of-band cryptoprocessors that conceal a private key. The private key corresponds to a public key that is used to encrypt a session key and information, both of which are passed to and through cloud based storage, all while remaining encrypted. The encrypted material is communicated from the cloud to another of the user's devices where the encrypted material is decrypted within a secure out-of-band cryptoprocessor (using the private key that corresponds to the aforementioned public key) located within the device. The embodiment allows for secure provisioning of the private key to the devices. The private key is only decrypted within the cryptoprocessor so the private key is not “in the open”. Other embodiments are described herein. | 09-18-2014 |
| 20140281486 | COMMUNITY-BASED DE-DUPLICATION FOR ENCRYPTED DATA - Technologies for de-duplicating encrypted content include fragmenting a file into blocks on a computing device, encrypting each block, and storing each encrypted block on a content data server with associated keyed hashes and member identifications. The computing device additionally transmits each encrypted block with an associated member encryption key and member identification to a key server. As part of the de-duplication process, the content data server stores only one copy of the encrypted data for a particular associated keyed hash, and the key server similarly associates a single member encryption key with the keyed hash. To retrieve the file, the computing device receives the encrypted blocks with their associated keyed hashes and member identifications from the content data server and receives the corresponding member decryption key from the key server. The computing device decrypts each block using the member decryption keys and combines to blocks to generate the file. | 09-18-2014 |
| 20140331315 | EYE MOVEMENT BASED KNOWLEDGE DEMONSTRATION - Embodiments of methods, apparatuses, and storage mediums associated with eye movement based knowledge demonstration, having a particular application to authentication, are disclosed.
