A method for controlling access to data of a disc, comprising the steps of determining whether or not information intrinsic to a writable disc has been detected from data that had been read from the disc; when the determined result represents that information intrinsic to a writable disc has been detected, determining that the disc is a writable disc and at least restricting a regular operation of the disc; and when the determined result represents that information intrinsic to a writable disc h...

A method and computer executable program code are disclosed for performing one or more maintenance tasks on a remotely located computer connected to a server computer via a data network.

Packets on a computer network are low pass filtered using a low and slow network reconnaissance detector to generate a spectrum of packets that are anomalous, i.e., are not commonly occurring IP packet traffic on the computer network. The low and slow network reconnaissance detector includes a low-frequency low-amplitude attenuation function module that adjusts an interest level for a particular network event based upon a number of occurrences. The low and slow network reconnaissance detector al...

A method and system for using a key lease in a secondary authentication protocol after a primary authentication protocol has been performed is described. In one embodiment, the primary authentication protocol comprises a strong, secure, computationally complex authentication protocol. Moreover, the secondary authentication protocol comprises a less complex (compared to the primary authentication protocol) and less secure (compared to the primary authentication protocol) authentication protocol w...

A server including a dual channel communications module operable to establish a communication session between the server and a client is provided. The server may be operable to receive a dual channel communication packet from the client. In a particular embodiment, the dual channel communication packet may include a header in a data payload. The header includes a client external IP address, and the data payload includes an encoded port command having a client internal IP address and a client dat...

An agent device is connected with one or more image-forming devices in a local network having a firewall provided therein. A management device carries out remote management of the image-forming devices in the local network through the Internet. The agent device includes a command receiving unit which starts connection with the management device and receives a management command from the management device via the firewall, the command being sent by the management device in response to the connect...

Communication systems and methods transfer information between a client device and a vendor device through a firewall between the client device and the vendor device by using a communications protocol that will normally allows pass through the firewall and/or by e embedding the information in a file format that will normally pass through the firewall. The information can be transmitted using the hypertext transfer protocol, and/or is embedded in an HTTP document or in an e-mail message. If the c...

A method for protecting the identification of a subscriber when a service provider transmits a subscriber request to a content provider in a distributed network environment, such as Internet. After the user sends a request to a service provider to which he has subscribed, the service provider encrypts the user identifier before transmitting this request with the encrypted user identifier to the content provider. Upon reception, the content provider uses an authentication Web Service supplied by ...

In electronic commerce (e-commerce) sites that are executed on a single e-commerce application, a user's session is only associated with a single user identity for e-commerce site domain. Acting under a single identity across the site may not be desired. There may be requirements to associate an individual user with one or more separate identities within parts of the site. Aspects of the invention provide a method, system and computer program product for managing multiple user identities for a u...
