Network authorization system and method using rapidly changing network keys
A system and method for authorizing a client device to access a host device based on timestamps including preferably at least two time units. Both devices contain multiple sequence tables that relate an order of time units to the value of one of the time units. Both devices also contain multiple string tables that relate strings to values of the time units within the timestamps. When the client device wants to access the host, it generates a first timestamp and sends the host device the first timestamp and the character strings from host tables related to the value of time units of the first timestamp. The host tables are known to all authorized client devices within the network. The strings are ordered according to a sequence table in the client device and the host device. When received, the host device compares the received characters strings to the character strings within its host string table based on an order determined by its host sequence table. If the character strings and order match, the host sends the client a second timestamp and the process is repeated using the second timestamp and sequence and string tables associated with, and known only to, the client device and the host device. In addition, the client, which may be monitored or controlled by the host, is able to request ongoing re-verification of the hosts authorization to detect and prevent unauthorized access from a third party. The rapidly changing timestamps and network keys eliminate recursive efforts to access these protected devices from an unauthorized third party. |

Seamless authentication for an application development platform
Various embodiments concern mechanisms for facilitating communication between network-accessible platforms for developing, hosting, or running hybrid applications that utilize resources hosted across multiple platforms. Hybrid applications cause messages or “calls” to be passed between the platforms that must be authenticated. For example, when a call is placed by a Heroku platform to a Force.com platform, the call must be authenticated for security purposes. If Heroku has not already been authenticated when the call is submitted, an authentication process is invoked. An event listener can be used to register details regarding the initial callout task, and then register or “fire” an event when the authentication process is successfully completed. Registration of the initial callout task completely separates the authentication process from the resource being invoked. Requests can be completed without requiring further user input using at least some of the details registered by the event listener. |

Secure access to individual information
A facility stores a person's personal information (“PI”) on a portable storage device (“PSD”) of the person. In some cases, the PSD bears a fax number mapping uniquely to the person; when a fax containing the person's PI is sent to this fax number, the facility stores an encrypted version of the PI on a relay server (“RS”). When the PSD connects with an access device, the encrypted version of the PI is retrieved from the RS and stored on the PSD. In some cases, the PSD bears a non-textual visual symbol; when its images is captured by a device such as a smartphone, an identifier encoded in the symbol is used to transmit encrypted PI to the RS. In some cases, each access device reports aggregates of personal data to an analysis server.

Distributed management of a storage system
Systems, apparatuses, methods, and computer-readable storage mediums for performing lease-based fencing using a time-limited lease window. During the time-limited lease window, writes to a shared storage medium are permitted, while writes are denied for expired leases. When a successful heartbeat is generated for a primary storage controller, the lease window is extended for the primary storage controller from the time of a previous heartbeat. Accordingly, a prolonged stall between successive heartbeats by the primary storage controller will result in the newly extended lease being expired at the time it is granted. This scheme prevents a split brain scenario from occurring when a secondary storage controller takes over as the new primary storage controller in response to detecting the stall. |

Domain name system CNAME record management
A method and apparatus for managing CNAME records such that CNAME records at the root domain are supported while complying with the RFC specification (an IP address is returned for any Address query for the root record). The authoritative DNS infrastructure acts as a DNS resolver where if there is a CNAME at the root record, rather than returning that record directly, a recursive lookup is used to follow the CNAME chain until an A record is located. The address associated with the A record is then returned. This effectively “flattens” the CNAME chain. This complies with the requirements of the DNS specification and is invisible to any service that interacts with the DNS server. |
