A Web server indicates which device, user, software, and network properties it can use to generate personalized content for a requesting user. The Web server also indicates which properties are actually required for it to generate any meaningful content at all. Using this mechanism, the client can optionally query the user for permission before including requested information in the request. Furthermore, the client device can save network bandwidth by only transmitting information that the server will use.

Methods, systems and apparatus for facilitating access by a user to a resource of an on-line service via a data communications network, the resource being accessible via an entry page of the service. A method includes checking whether a user condition, prestored in the network, is satisfied, the user condition being associated with the user and relating to the resource. If the condition is not satisfied, the entry page is sent to the user via the network. If the condition is satisfied, the entry page is modified by adding an indication relating to the resource. The modified entry page in then sent to the user advantageously, the method also includes transmitting to the user a notification message in response to, and indicative of, the condition being satisfied.

Facilitating access to a resource of an on-line service

A method of establishing a trustworthiness level of a participant in a communication connection between a first communication partner and a second communication partner is proposed whereby the communication behavior is adapted to the established trustworthiness level. The participant is equipped with a trustworthiness certificate and a therefrom separated securely stored participant private key. The first communication partner receives the trustworthiness certificate from the participant wherefrom the trustworthiness level is derived and established. The first communication partner tests whether the trustworthiness certificate belongs to the participant by using the participant private key. In case the trustworthiness certificate is confirmed by the test to belong to the participant, the first communication partner communicates the established trustworthiness level to the second communication partner. Then, at least one parameter of the communication behavior is chosen in dependence of the established trustworthiness level.

A method of transmitting information data from a sender to a receiver via a transcoder is proposed. The information data comprises confidential information data which is encrypted and non-confidential information data. Security information and transcoding-type information is sent together with the partly encrypted information data to the transcoder which uses the security information and transcoding-type information during a transcoding step. The encrypted confidential information data is thereby transcoded without using its content while the non-confidential information data is transcoded, having access to its content.

A method, system, and computer program product for establishing security parameters that are used to exchange data on a secure connection. A piggy-backed key exchange protocol is defined, with which these security parameters are advantageously exchanged. By piggy-backing the key exchange onto other already-required messages (such as a client's HTTP GET request, or the server's response thereto), the overhead associated with setting up a secure browser-to-server connection is minimized. This technique is defined for a number of different scenarios, where the client and server may or may not share an encoding scheme, and is designed to maintain the integrity of application layer communication protocols. In one scenario, a client requests a server to propose a message encoding scheme. If the client has security-sensitive data to transmit with its request, it waits for the proposed scheme before sending this sensitive data to the server. Otherwise, the server may inform the client of the message encoding scheme in the same transmission used to send a response to a client's request.

Methods, systems and computer program products are provided which provide profile information associated with a client to a server by generating, at the client, a profile document containing profile information associated with the client and incorporating in the profile document a designator which indicates that profile information identified by the designator is not provided by the client and is provided by a network intermediary in a path between the client and the server. The designator in the profile document is encrypted utilizing a key associated with the client and the profile document with the encrypted designator transmitted from the client to the server utilizing the path. Method, systems and computer program products corresponding to the network intermediaries are also provided.

A method and apparatus for automated transcoder selection in a data processing system for transcoding content using a set of transcoders. A request is received for the content from a client, wherein the request includes a set of characteristics. A transcoder is selected from the set of transcoders having a best match to the set of characteristics. The content is transcoded using the transcoder to form transcoded content.

Methods and apparatus are provided for transcoding a data message, comprising a plurality of data fields (f-f) and an authentication code (Sgn(h)), to produce a transcoded message for transmission to a destination device (). The transcoding methods can be applied to such a data message which is received from a source device () wherein said data fields (f-f) have been coded in accordance with a first coding system, whereby respective data field codes (h-h) are generated for said data fields (f-f) and a message code (h) is derived from said data field codes (h-h), and wherein said message code (h) has been coded in accordance with a second coding system to generate said authentication code (Sgn(h)). For each data field (f-f) of the received data message it is decided whether to maintain, modify or omit that field. For a field to be maintained, that field is maintained in the transcoded message. For a field to be omitted, that field is coded in accordance with said first coding system to generate an omitted field code dependent upon the data field code (h) for that field, and that field is replaced by said omitted field code in the transcoded message. For a field to be modified, that field is coded in accordance with said first coding system to generate a modified field code dependent upon the data field code (h) for that field, and that field is replaced by a modified field, comprising modified data (f') and said modified field code, in the transcoded message. The received authentication code (Sgn(h)) is also included in the transcoded message. Sufficient information is thereby included in the transcoded message to enable the destination device to verify the transcoding operation.

Transcoding in data communications

A method, system, and computer program product for exchanging supplemental information fields between a client and server. This supplemental information can then be used by the server to complete a client's request for content stored at a particular location. For example, the supplemental information may be used to provide a customized response, or for access control to sensitive data. Preferably, the REDIRECT message of the Hypertext Transfer Protocol (HTTP) or the Wireless Session Protocol (WSP) is used to request the supplemental information, encoding a comma-separated list of attribute names in a request header for the desired supplemental information. This solution is designed to be backward-compatible.
