24358 results about "Internet privacy" patented technology

Internet privacy involves the right or mandate of personal privacy concerning the storing, repurposing, provision to third parties, and displaying of information pertaining to oneself via the Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing.

Access management system and method employing secure credentials

A security architecture has been developed in which a single sign-on is provided. Session credentials are used to maintain continuity of a persistent session across multiple accesses to one or more information resources, and in some embodiments, across credential level changes. Session credentials are secured, e.g., as a cryptographically secured session token, such that they may be inspected by a wide variety of entities or applications to verify an authenticated trust level, yet may not be prepared or altered except by a trusted authentication service. Some embodiments of the present invention associate trust level requirements with information resources. Authentication schemes (e.g., those based on passwords, certificates, biometric techniques, smart cards, etc.) are associated with trust levels, and in some embodiments, with environmental parameters. For example, in one configuration, a login service obtains login credentials for an entity commensurate with the trust level requirement(s) of an information resource (or information resources) to be accessed and with environment parameters that affect the sufficiency of a given credential type. Once login credentials have been obtained for an entity and have been authenticated to a given trust level, session credentials are issued and access is granted to information resources for which the trust level is sufficient. Advantageously, by using the session credentials access is granted without the need for further login credentials and authentication. In some configurations, session credentials evidencing an insufficient trust level may be remedied by a session continuity preserving upgrade of login credential.

Authentication and authorization methods for cloud computing security

An authentication and authorization plug-in model for a cloud computing environment enables cloud customers to retain control over their enterprise information when their applications are deployed in the cloud. The cloud service provider provides a pluggable interface for customer security modules. When a customer deploys an application, the cloud environment administrator allocates a resource group (e.g., processors, storage, and memory) for the customer's application and data. The customer registers its own authentication and authorization security module with the cloud security service, and that security module is then used to control what persons or entities can access information associated with the deployed application. The cloud environment administrator, however, typically is not registered (as a permitted user) within the customer's security module; thus, the cloud environment administrator is not able to access (or release to others, or to the cloud's general resource pool) the resources assigned to the cloud customer (even though the administrator itself assigned those resources) or the associated business information. To further balance the rights of the various parties, a third party notary service protects the privacy and the access right of the customer when its application and information are deployed in the cloud.

System and method for verifying delivery and integrity of electronic messages

A server receives a message from a sender and transmits the message through the Internet to a recipient. The server normally transmits the message in a first path through the Internet to the recipient. When the sender indicates at a particular position in the message that the message is registered, the server transmits the message in a second path through the Internet to the recipient. The sender can also provide additional indications in the message to have the server handle the message in other special ways not normally provided by the server. After learning from the receipt or the recipient's agent through the Internet that the message was successfully received, the server creates, and forwards to the sender, an electronic receipt. The receipt includes at least one, and preferably all: the message and any attachments, a delivery success / failure table listing the receipts, and the receipt times, of the message by the recipient's specific agents, and the failure of other agents of the recipient to receive the message and a digital signature of the message and attachments subsequently. By verifying that the digital signature on the sender's receipt matches the digital receipt at the server, the server can verify, without retaining the message, that the receipt is genuine and that the message is accurate.

Computer services for assisting users in locating and evaluating items in an electronic catalog based on actions performed by members of specific user communities

A Web based system provides informational services for assisting customers in selecting products or other types of items from an electronic catalog of a merchant. Users of the system can create and join user communities, such as communities based on user hobbies, localities, professions, and organizations. The system also supports implicit membership communities that are based on email addresses (e.g., all users having a “” email address), shipping / billing addresses, and other known user information. Using purchase history data collected for online users, the system automatically identifies and generates lists of the most popular items (and / or items that are becoming popular) within particular communities, and makes such information available to users for viewing. For example, in the context of an online book store users of the community may automatically be presented a Web page which lists the bestselling book titles among users, or may be sent email notifications of purchase events or hotselling books within the community. Another feature involves automatically notifying users interested in particular products of other users (preferably other members of the same community) that have purchased the same or similar products. For example, in one embodiment, when a user accesses a book detail page, the detail page is customized to include the names and email addresses of other members of the user's community that recently purchased the same book.
