  • Patent number: 7421728
    Abstract: In interactive television, a broadcaster may broadcast triggers to a great many receiver units prompting the receiver units to attempt to send requests to a single destination on the Internet at roughly the same time. Such a large number of simultaneous requests can give rise to throughput problems and server overload. A receiver unit in accordance with the invention, rather than immediately attempting to send a request, waits a period of time (for example, a random period) before sending the request so as not to overload the server. In one embodiment, a trigger is received on an interactive television receiver unit prompting the viewer to select an icon. If the viewer selects the icon, then a browser in the receiver unit retrieves a web page on the Internet identified by a URL in the trigger. The web page includes an indication of a destination, scheduling information, and a form area. The viewer enters user information in association with the form area.

  • Patent number: 7421729
    Abstract: Disclosed is a system for inserting indicators, such as tags and markers, in a video stream. The tags and markers can be inserted automatically using a database, or manually using an operator input station that supplies standard tags and markers for easy insertion. The information can be accessed with the database functioning as a look-up table, or using a comparator that compares a time code with stored table information. Also disclosed is the generation of supplemental video signals that can be combined with a video signal to provide supplemental information that varies on a regional basis. The present invention also discloses the use of indicators to access Internet web sites to generate enhanced video signals. The indicators can be transmitted by embedding them in the streaming video, in the video blanking interval, encoding them as a separate data PID or placing them on a back channel.

  • Patent number: 7421730
    Abstract: A providing computer system may receive a request, via a stateless protocol, to access a resource. An access control application may refer to administrative rules to set validation information associated with the request. Validation information may be in the form of electronic text that is stored in a location such as a cookie or state-table. Validation information may indicate the state of a session associated with a resource, such as whether a session is in a logged-in or logged-out state. When a request is received, validation information and authentication information may be utilized together to determine if access to a resource should be granted. When access to a resource is granted or denied, validation information may be updated to indicate that the state of the session has changed.

  • Patent number: 7421731
    Abstract: A user, by way of a computing device, requests and receives content from a first server at the computing device. An authentication response is also received from the first server at the computing device of the user. The authentication response includes an address of the second server and an executable script. The computing device of the user executes the executable script by issuing a request to the second server for state information corresponding to the user, receiving the state information from the second server; and determining, based on the state information, whether the user is authenticated to the second server. If the user is not authenticated to the second server, the computer device of the user displays a login module that is visually associated with the first server. Such login module collects login information for authenticating the user to the second server.

  • Patent number: 7421733
    Abstract: When a user successfully logs into an account, the user is provided with a first-class login token, which entitles the user to one or more unsuccessful login attempts without experiencing delays the user would otherwise experience. If attempts with a second-class login token or an expired first-class login token is impermissible, a subsequent login attempt is subject to delays the user would otherwise not experience. The delays minimize the effectiveness of dictionary attacks. Additionally, if the user attempts to login without a login token or an invalid login token, the login attempt is impermissible and the user is provided with a second-class login token for use in a delayed, subsequent login attempt.

  • Patent number: 7421735
    Abstract: A method, system and apparatus are described for avoiding the use of a web-server or generic security when providing network administration services remotely to managed entities using wireless technology. Instead a true Proxy device, not operating as a web-server, is used to preprocess all command traffic from wireless input devices (WID). The intervention between the WID and the managed entities of the Proxy isolating the managed entities from the WID, enhanced by encoding using a novel messaging protocol, further enhanced by a novel security model based on multiple pre-shared keys and algorithms together with identifiers and passwords that are not transmitted, achieves several bandwidth and security advantages including the ability to deliver TELNET services across the Internet and behind a firewall.

  • Patent number: 7421737
    Abstract: Evasion detection is disclosed. Techniques are provided for network security, including comparing a received header value to a baseline header value, determining based on the comparison whether a threshold has been satisfied, and generating an alert if the threshold has been satisfied. Header values may be representative of data included in packet headers that, depending upon a data communication protocol in use (e.g., TCP, IP, etc.) may include information such as a time-to-live (TTL) value or IP options. After retrieving a received packet's header value, it is compared to a baseline header value and, in combination with evaluating a flip count threshold, used to detect an evasion attempt.

  • Patent number: 7421740
    Abstract: Transactional access control information extracted from a transactional data source and used by a transactional application program is received at an analytical application program used for analytical processing. Each entry in the transactional access control information identifies a user that is permitted to access a data object that is stored in the transactional data source. The received transactional access control information is translated into analytical access control information for use by the analytical application program. Entries in the analytical access control information identify users that are able to access data objects that are stored in an analytical data store used by the analytical application program and correspond to data objects stored in the transactional data source.

  • Patent number: 7421741
    Abstract: A system and method of encrypting digital content in a digital container and securely locking the encrypted content to a particular user and/or computer or other computing device is provided. The system uses a token-based authentication and authorization procedure and involves the use of an authentication/authorization server. This system provides a high level of encryption security equivalent to that provided by public key/asymmetric cryptography without the complexity and expense of the associated PKI infrastructure. The system enjoys the simplicity and ease of use of single key/symmetric cryptography without the risk inherent in passing unsecured hidden keys. The secured digital container when locked to a user or user's device may not open or permit access to the contents if the digital container is transferred to another user's device. The digital container provides a secure technique of distributing electronic content such as videos, text, data, photos, financial data, sales solicitations, or the like.
