Abstract:
A SYSTEM AND METHOD FOR SECURE COMMUNICATION OVER WIRELESS NETWORK IS PROVIDED BY UTILIZING DUTY-SHARED AUTHENTICATED GROUP KEY TRANSPORT TO ENABLE SYMMETRIC-BASED AUTHENTICATED GROUP COMMUNICATION OVER WIRELESS NETWORK. THE SYSTEM (100) INCLUDES AN INITIATOR (102) CONFIGURED TO EXECUTE A SECURE GROUP MANAGER MODULE (108) IN ANNOUNCING GROUP SESSIONS, AUTHENTICATING AND DISTRIBUTING AUTHENTICATED SESSION TOKENS. A PARTICIPANT (104) IS CONFIGURED TO EXECUTED A SECURE GROUP HANDLER MODULE (112) IN AUTHENTICATING, RECEIVING A GROUP SESSION KEY AND JOINING SAID GROUP. A TRUSTED AUTHORITY (106) IS IN COMMUNICATION WITH THE INITIATOR (102) AND PARTICIPANT (104). THE TRUSTED AUTHORITY (106) IS CONFIGURED TO EXECUTE A SECURE GROUP ADMINISTRATOR MODULE (110) IN MEDIATING AND PROVIDING AUTHENTICATED SESSION TOKENS. THE INITIATOR HOST DOES NOT REQUIRE ANY SPECIFIC CONFIGURATION AND CAN BE ANY OF THE PARTICIPANTS. THE SECURE GROUP MANAGER MODULE GENERATES THE GROUP KEY WHILE THE SECURE GROUP ADMINISTRATOR MODULE MONITORS THE SESSION WHICH PROVIDES FOR SEPARATION OF DUTY (INITIATOR-ASSISTED). ENCRYPTION OF THE NONCE AND GROUP SESSION KEY IS PROVIDED BY UTILIZING AUTHENTICATED ENCRYPTION WITH FRESHNESS OF DYNAMIC CREDENTIAL ASSIGNMENT (SESSION IDs). THE MOST ILLUSTRATIVE DRAWING IS FIG. 1.

The system (100) allows audiences or viewers to request for specific or all pages of the document currently being presented over a network. The system (100) comprises of a session module (110), a security module (120), a screen processing module (130), a connection module (140), and an on-demand module (150). The on-demand module (150) includes a document handler module (151), a subscription and notification module (152) and a second main module (153). FIG. 1
Abstract:
The present invention relates to a system (1000) and method for distributing presentation content. The system (1000) comprising a presenter device (100) configured to encode presentation content, a presentation content server (200) configured to decode incoming video into a series of frame, process a plurality of audience request, and distribute frames selectively to a plurality of audience devices (300), and the audience devices (300) configured to request presentation content, download the requested content, and store the content. The presentation content server (200) comprising a dynamic group assignment module (250) configured to arrange the audience devices (300) into different groups for content distribution, a selective content delivery module (260) configured to determine whether the requested frame is beneficial to the audience, and an opportunistic distribution module (270) configured to exploit request variations from the audience devices (300) to allow late joiners and punctual audience are synchronised in terms of the number of retrieved frames.
Abstract:
The present invention relates to a system (10) for authenticating a media content comprising: a main server (1) for distributing the media content; and at least a client (3) connected to the main server (1) for receiving the media content, characterized in that the system further comprising: a verifier generator (4) operating with the main server (1) for generating key parameter values to extract source verifier data from the media content, wherein the generated key parameter values and source verifier data are sent to the client (3) for authenticating the media content; and a verifier extractor (5) operating with the client (3) for extracting client verifier data from the received media content based on the key parameter values generated by the verifier generator (4), wherein the client verifier data are compared with the source verifier data received from the main server (1) for determining the authenticity of the media content.

Abstract:
A method of performing automatic callback notifier on reversed missed calls through network based enabler helps a caller to reach a callee by making reference to the presence status and subscribed to the callback service (115) provided by the network service providers. This method extends the functionality of existing device with a feature that prompts users to auto callback the callee who cannot be reached previously but is currently becoming available. This feature works by determining the presence status of the callee (215). Whenever the callee turns his status presence from "Not available" to "Available", the caller device will be acknowledged. This allows the caller device to automatically prompt the caller to proceed calling back the same callee (225).

Abstract:
The present invention relates to a system (100) and method for screen capturing for real-time transmission. In particular, the present invention relates to a system (100) and method for capturing desktop screen adaptively based on current desktop application or content, local computing resource and local communication resource. The system (100) comprises of a Graphical User Interface (GUI) (10), a Session Module (20), a Security Module (30), a Connection Module (40) and a Screen Analysis Module (50).
Abstract:
A centralized VoIP network system (10) comprises a plurality of endpoints (12a-12f) and a SIP server (11) coupled to said endpoints (12a-12f) in said network (10), said server (11) operable to determine the codec bitrate from the network bandwidth availability based on the predetermined threshold values.
Abstract:
A method (100) for session transfer mechanism between communication devices. The method (100) comprises the steps of triggering a session transfer (102) on an first device having an active session with a corresponding device, identifying a second device (104) from a plurality of devices for the session transfer, transferring the active session (106) transpiring between the first device and the corresponding device to between the second device and the corresponding device, and reclaiming the active session (108) transpiring between the second device and the corresponding device if a session reclaiming is triggered on the first device.
