Abstract:
A computer implemented method and system for uniform, consistent, stateless, and deterministic consistent hashing for fixed size partitions. The method comprises receiving server information for a plurality of servers in a server pool; ordering the server information for the plurality of servers; calculating a mean number of partitions per server in the server pool; calculating a first maximum allowed number of partitions for a server by applying a floor function to the calculated mean number of partitions per server in the server pool; in the order of the ordered server information, assigning partitions to servers based on a hashing function, using the first maximum allowed number of partitions per server; calculating a second maximum allowed number of partitions for a server by applying a ceiling function to the calculated mean number of partitions per server in the server pool; in the order of the ordered server information, assigning partitions to servers based on a hashing function, using the second maximum allowed number of partitions per server; and assigning unassigned partitions wherein assigning comprises: for each unassigned partition, mapping the partition to a server with the least number of assigned partitions at a time of the mapping.
Abstract:
A method for providing a proof-of-work challenge based on hash mining for reducing spam attacks comprising: receiving an email message from a client device; determining a level of trustworthiness of the client device; generating a challenge message based on the determined trustworthiness of the client device; transmitting the challenge message to the client device; receiving a response to the challenge message from the client device; and forwarding the email to one or more recipients when the response to the challenge message is correct.
Abstract:
A method of remote correction of invalid contact file syntax is disclosed. The method comprising receiving a file comprising information associated with one or more contacts; attempting to import the received file on a target device; in response to an import failure: depersonalizing the received file of contact information; identifying a location within one or more contacts the depersonalized file which caused the import failure, wherein the location is stored as metadata; transmitting the depersonalized file and the metadata to a remote server for repair; and receiving a repaired depersonalized file; repairing the received file of contacts based on the repaired depersonalized file; and importing the file of contacts on the target device.
Abstract:
Embodiments of the present invention are directed to an improved apparatus, system and method of edition-based redefinition for tables. When a new edition of an application is created, editions on the tables pertaining to the application are created. These tables typically store application configuration/reference data that control what the application does. These tables are altered to contain a new “edition” column. Keys on these tables include the “edition” column. Each table is partitioned on the “edition” column such that cleaning up data used by an edition is easy. Views are created on these tables, which make the “edition” column invisible by the application while ensuring that only data that can be accessed is the data for the correct edition. The current “edition” of the application stays fully operational while the application is upgraded because the configuration data in the tables does not change until the new “edition” is turned on.
Abstract:
A computer implemented method and apparatus for just-in-time transcoding. The method comprises receiving at a media server, video content, wherein the video content comprises a plurality of key frames and delta frames; generating, in response to receiving the video content, metadata, wherein the metadata is a lookup table of the plurality of key frames; storing the video content and the metadata; receiving a first request to view video content; generating a playlist for the video content; receiving a second request to view a video segment of the video content; and transcoding the video segment; and transmitting the transcoded video segment.
Abstract:
Embodiments of the present invention relate to event notifications on an end-user device of events that are important to a user of the device. The user is typically subscribed to a service that pulls events from a plurality of sources indicated by the user. The sources include a native address book on the device, a social network(s), a professional network(s), and/or another remote location(s) on the Internet. Around the occurrence of an event, the service allows for automatically generating an electronic wish and for purchasing a gift to be presented to one or more recipients associated with the event. The service can transmit the content in various forms and can include a monetizing scheme. The service is able to intelligently determine which events are important to the user such to alert the user of only those relevant events, and to intelligently select an appropriate channel for transmitting the content.
Abstract:
A client device is coupled with a server. The client device prompts a user to enter a number associated with a mobile device, which can be the client device, and generates data including a code. The code is typically hidden from the user when the code is generated and is saved on the client device. The client device transmits the number entered by the user and the code generated by the client device to the server, which sends a message, including the code, to the mobile device associated with the number. The client device prompts the user to enter the code included in the message. Validity of the number is based on one or more factors, including the accuracy of the code entered by the user. In addition, validity of the number can also be based on whether the second user input was entered within a predetermined time limit.
Abstract:
A Mobile Content Transfer (MCT) system requires no special equipment or a physical connection to any hardware. The MCT system has no hardware limitation with regard to the number of simultaneous transfers. The MCT system can be used to transfer data from anywhere at any time by anyone without the need to go into a retail location. The MCT system can transfer and store all or some data classes to increase adoption and usage of the MNO Cloud. The MCT system eliminates the need for dedicated personnel allowing more personnel to attend to new sales revenue opportunities. The MCT system eliminates the need to wait for a single machine or individual and empowers the end-user to perform the transfer of their data whenever and wherever they choose. The MCT system provides the option to safely and securely store data in the cloud that can be restored to another device.
Abstract:
Embodiments of the present invention relate to an enterprise address management system. In the enterprise address management system, addresses are imported and consolidated from external sources and stored in a database. The addresses are continuously updated from the same or different external sources while a history for each address is maintained to allow for retrieval and use of previous information. The history of each address is updated as a corresponding address transitions through an address life cycle as defined by a subscriber. The address life cycle typically is represented by a state model. In some embodiments, the enterprise address management system allows each subscriber to define and configure its own address life cycle state model and to control the flow of addresses through that life cycle.
Abstract:
A system and method are disclosed which may include receiving an activation request from a first subscriber device at a communication convergence platform; identifying a service provider associated the first subscriber device; composing a service activation request compatible with a communication protocol for the identified service provider; and transmitting the service activation request from the platform to the identified service provider.
