In this data receiving apparatus, when a password is not inputted or when an incorrect password is inputted by a user when a display is in a state of password input screen, the display indicates only a received mail list for mails from persons who are identified by personal data sets stored in advance which do not have a secret flag. The display also indicates the number of all the mail data sets, including the mail data sets from persons for which the secret flag is set.
Abstract:
A secure data communication system is shown for transferring digital data from one computer directly to another. The system includes specially adapted switches interconnected by high bandwidth private data lines. Subscribers use low cost, highly specialized computer mailboxes that connect to the switches over the public telephone network and are connected to subscribers' computers. Each mailbox has a unique identification number burned on a PROM located therein. Switches verify the identification of a mailbox both through the unique identification number and by a series of callbacks to the mailbox's registered telephone number to ensure that the mailbox is properly located. A network scheduler receives pending transaction requests and calculates a time when the sending and receiving mailbox are both available for the transfer. The data may be compressed and/or encrypted during the transfer.
Abstract:
A system and method enabling a user to remotely access an electronic calendar using a telephone network is provided. The system includes the electronic calendar for storing a plurality of schedules and a scheduler for accessing the schedules as a function of input signals received over the telephone network. Each schedule contains future appointments and events for either daily, weekly or other data interval periods. The scheduler enables selective retrieval and display of the appointments and events for any selected time period. The system is coupled to interfaces allowing the schedule information to be transmitted as audio information, video information, or e-mail information. The scheduler can compare the schedules to one another to automatically generate common meeting times. The common meeting time can then be transmitted to the various attendees using e-mail, audible instructions or voice mail.
Abstract:
A communications network simultaneously transmits a single message to a number of recipients. This is called a "multicast" transmission. The communications network should have a recipient list database (1302) to receive a list of recipient addresses, a message database (1304) to receive and store the message, and a message delivery system (1306) to send the message to a number of recipients. The communications network may be adapted to collect acknowledgements or responses to a multicast message. If so, the communications network should have a calling record (1308) for storing message delivery information, a response record (1310) for receiving and storing recipient response information, a response processor (1312) for processing the response information, and a response delivery system (1314) for delivering the processed response. The multicast capability may be integrated with other communications network services, such as Personal Location Service, Personal Communications Internetworking, call blocking, etc.
Abstract:
A method of providing a document to a client coupled to a server is provided. The server provides a number of Internet services to the client, including functioning as a caching proxy on behalf of the client for purposes of accessing the World Wide Web. The proxying server includes a persistent document database, which stores various attributes of all documents previously retrieved in response to a request from a client. When a Web document is retrieved from a remote server in response to a request from the client, the database is consulted and the stored information relating to the requested document is used by the server in transcoding the document. The document is transcoded for various purposes, including to circumvent bugs or quirks found in the document, to size the document for display on a television set, to improve transmission efficiency of the document, and to reduce latency. The transcoder makes use of the document database to perform these functions. The document database is also used for prefetching previously requested documents and images and for reducing latency when downloading images to the client.
Abstract:
Computer-implemented methodology is described which allows any user to access a "network client" machine (e.g., PC, ATM machine, cell phone, or the like) which is connected to a network but which does not know the authentication of the user. With only the user's password, the client machine is able to initiate a communication session with a server and identify the user to the server as the person who the server truly expects. The method allows both the client and the server to each identify the other as authentic (not a middle man or imposter)--that is, without compromise in security along the communication link. In this manner, the user can access information from the true server in a secure manner and bring that information down to the local client, for instance, for use in a JAVA application.
Abstract:
A message-sending system provides for entering an identifier uniquely associated with an intended recipient and a message for the intended recipient in a WEB page, and associating the identifier with the intended recipient's pager routing information from a database accessible to a WEB Server providing the WEB page. A successful association leads to formatting a pager message for the intended recipient, and forwarding the formatted message to a pager system serving the intended recipient. In some embodiments success or failure of the pager message is reported back to the original sender.
Abstract:
A local server has a connection to a client and to a remote server over the Internet. The local server receives a request for an audio file from the client and, in response, transmits a requests for the audio file to the remote server. Upon receiving the audio file, the local server transcodes the audio file received from the remote server and then transmits the transcoded audio file to the client. Transcoding may include changing the audio file type, compressing the audio file, reducing the number of audio channels, or reducing the sampling rate of the data. The local server determines the extent and type of transcoding to be performed on the audio file as the audio file is downloaded from the remote server. The extent and type of transcoding are based on the file formats which the client is capable of handling, the size of the requested audio file, the memory capacity of the client, the bandwidth of the connection between the local server and the client, and the desired level of audio quality. Transcoding may be performed on-the-fly while the requested audio file is being downloaded to the local server from the remote server and while the modified audio file is being downloaded from the local server to the client.
Abstract:
A multimedia collaboration system that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data--in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mixing technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.
